What do a 15-year-old hacker, Julian Assange, inattentive administrators, and the War Thunder forum have in common? They were all involved in data leaks from the Pentagon. This article will explore several of the most prominent examples of leaks linked to one of the world's most secure agencies, as well as discuss the experience of interaction between the U.S. Department of Defense and ethical hackers.

Jonathan James

According to the U.S. Department of Defense, the first hacking of the Pentagon occurred in 1999 by a 15-year-old named Jonathan James, known among hackers as C0mrade. Jonathan found a server with a backdoor that allowed anyone to connect. He connected to the server, installed a sniffer, and gained access to all the traffic. This server belonged to a unit of the Department of Defense. Within a month, the boy intercepted numerous credentials, which he used to access the Department of Defense computers and download a vast amount of emails from Pentagon employees' mailboxes. Jonathan did all this not for personal gain but out of simple curiosity. Naturally, the intrusion was noticed, investigated, and the juvenile perpetrator was found. Jonathan's case is unique because he became the first minor in the U.S. to go to jail specifically for hacking.

Gary McKinnon

Two years after Jonathan James's story, another young hacker managed to breach this fortress alone. In January 2001, Gary McKinnon, a systems administrator from London, first broke into the American military computer system. Instead of wondering "how to hack the Pentagon," he simply found a flaw in the security system. Gary created a Perl program that identified administrator-status computers without a password. To the U.S. military ministry's embarrassment, there were many such machines. For 13 whole months, Gary studied the contents of Pentagon and later NASA computers unpunished. He was searching for evidence of extraterrestrial life and, according to him, found it. A year after his first intrusion, Gary was exposed, but he managed to avoid responsibility because a wave of protest arose, and the UK authorities did not extradite him to the U.S.

Julian Assange

Discussing whether the Pentagon was hacked, one cannot overlook Julian Assange, the founder of WikiLeaks. Since 2006, the portal has been publishing classified materials from the Pentagon and other U.S. law enforcement agencies. It is not known for certain whether Assange hacked government servers himself or if he received documents from third parties. But as the creator and distributor of information, he faces numerous charges, with a total criminal sentence of 175 years of imprisonment.

Edward Snowden

To extract and publicize classified Pentagon documents, hacking is not always necessary. Sometimes the danger lies within the employees themselves, who disagree with the methods of the military ministry. The most striking example is Edward Snowden. In 2013, he was an employee of the military system and had access to classified documentation. He learned about the massive U.S. surveillance of citizens of various countries around the world. Deciding to disclose the data, Snowden downloaded nearly 2 million secret documents onto a flash drive and took it out of the NSA office hidden in a simple Rubik's Cube. Then came the publications in the world media, major disclosures, accusations of espionage, fleeing the country, and a safe haven in Russia. It should be noted that there was also no selfish motive in this case.

Case of Jack Teixeira

In 2023, a loud scandal erupted related to the leak of classified Pentagon documents. Their photos appeared on the Discord platform, the 4Chan forum, Twitter, and some Telegram channels. Initially, it was thought that the Russians had hacked the Pentagon, but it later turned out that the leak was again related to a person working in the system and having access to secret information. Later, the world was shocked by footage of the arrest of Jack Teixeira—an Air Force pilot in red shorts being led by heavily armed American special forces. The information published by Teixeira contained secret documents concerning the conflict in Ukraine and revealing U.S. surveillance of partner countries. Jack was accused of espionage and now faces many years in an American prison.

Curious Cases

There have been many curious cases in the history of the Pentagon and similar agencies that led to the disclosure of official information. For example, last year a story surfaced about a typo that caused letters from the U.S. Department of Defense to go to mail addresses in Mali for years. Confidential information about U.S. (and French) military technology often surfaced on the War Thunder game forums so frequently that moderators had to publicly explain why their forum became a treasure trove of secret drawings. The U.S. military department did not overlook careless administrators either. Data can be found on at least one case when an unprotected Pentagon server with sensitive information was "shining" online for a long time. There are probably more such unpublicized incidents.

Pentagon and ethical hackers

If the human factor problem is solved by tightening internal policies toward employees, the Pentagon website and the entire U.S. Department of Defense infrastructure are protected by ethical hackers. As early as 2016, a government vulnerability search program called Hack the Pentagon was launched on the HackerOne platform. More than 100 potential breaches in ministry defense were discovered, and over 1,400 pentesters participated in the project. The number of participants is easily explainable. First, hacking the Pentagon online is the dream of any hacker. Secondly, the first bug bounty program of the Ministry of Defense was conducted on a paid basis. Individual payouts ranged from $100 to $15,000, with a total budget of $75,000. The next program was conducted in 2018 and focused on publicly accessible websites of the Ministry of Defense. 

By the end of 2020, the department was hacked more than 12,000 times, but within controlled tests. Hackers were no longer paid for finding vulnerabilities but were awarded points on the HackerOne platform. The start of the third bug bounty program of the Pentagon was announced in 2023. But this time, hackers were invited to try to penetrate systems that control mechanical operations, such as heating and air conditioning in the main building, the Pentagon's heating and cooling installation, a modular office complex, and a parking lot. The task of the hackers is to identify weaknesses and vulnerabilities and provide recommendations for improving and strengthening the overall security situation.

Conclusion

It is naive to think that in the modern world there are objects that simply cannot be hacked. And the Pentagon is no exception. Today we have told only a few stories related to hacking and data leakage from the U.S. military department. But there are many more incidents that have not been publicly disclosed. Meanwhile, the Pentagon does not close itself off and actively uses external specialists to find vulnerabilities and weak spots in the system. This is the right tactic that helps the ministry improve its cybersecurity and respond more intelligently to attempts at penetration.

Kindernothilfe (KNH) is a German non-profit organization dedicated to supporting vulnerable children in impoverished and underprivileged regions worldwide. Founded in 1959, it has made significant contributions as one of Europe’s largest charities dedicated to child aid. Operating in over 30 countries, Kindernothilfe emphasizes the importance of ensuring children’s rights and providing access to education, healthcare, child protection, and community development initiatives, all aimed at enhancing children’s living conditions and eradicating poverty.

The challenge: Finding a secure and user-friendly solution for global teams

Before choosing Passwork, Kindernothilfe relied on KeePass, a solution that limited scalability and lacked user-friendly features essential for a globally operating organization. With over 300 employees across more than 30 countries, the organization required a secure, scalable, and intuitive password management solution.

Doing so was crucial to meet the growing demands of its international team, especially for enhancing password sharing and access management capabilities for remote employees.

The solution: Switching to Passwork for improved security and simplified user access

Kindernothilfe opted for Passwork for its robust self-hosting capabilities, ensuring optimal data control and security. The seamless integration with SAML2 for Single Sign-On (SSO) streamlined access management across multiple platforms.

Furthermore, Passwork’s intuitive interface, along with its mobile app and browser extension, made it possible to manage passwords effortlessly from any device. The secure password-sharing features enhanced team collaboration, significantly reducing human error and improving overall security protocols.

The implementation: Gradual rollout and building a secure infrastructure

The implementation process took approximately two months. It was primarily focused on establishing and thoroughly testing the infrastructure to ensure Passwork met Kindernothilfe’s security requirements. The integration of SAML2 for Single Sign-On (SSO) was smooth and completed within a short timeframe.

To facilitate the successful implementation of Passwork, Kindernothilfe opted for a phased rollout rather than deploying the password management solution organization-wide all at once. They began with a smaller group of employees to showcase the benefits of the system and gradually promoted its use.

While organizing various promotional and educational activities, such as “Lunch and Learn” events, the organization encouraged employees to engage with Passwork. The goal was to achieve the point where at least 50% of the staff actively used Passwork before expanding the system to the entire organization.

The results: Increasing operational efficiency for cross-border teams

Currently, approximately 50% of the staff are actively using Passwork—a centralized, secure, and user-friendly solution for password sharing. This incremental approach not only ensured higher user engagement but also significantly strengthened security protocols across the organization.

By improving password management processes, Kindernothilfe increased its overall operational efficiency, especially for cross-border teams. Educational initiatives, such as “Lunch and Learn” sessions, were instrumental in raising awareness about Passwork and facilitating its successful adoption throughout the organization.

The introduction of children to technology is happening at an increasingly younger age. This early exposure to the digital world, while beneficial in many ways, also carries significant risks due to the evolving tactics of cybercriminals. Parents must stay updated on the latest cybersecurity threats targeting young internet users to ensure their safety. 

Today, we aim to shed light on various cybersecurity trends and provide practical advice for parents to safeguard their children's online presence.

AI and its impact on young users

Artificial Intelligence (AI) is rapidly transforming numerous industries, and its applications are becoming a part of daily life, from chatbots to personalized online shopping experiences. This technological advancement naturally attracts the curiosity of children, who often use AI tools for educational purposes or entertainment. A UN study indicated that approximately 80% of young participants interact with AI multiple times daily. However, these interactions are not without risks, including data privacy breaches, exposure to cyber threats, and inappropriate content.

Children often use AI applications for seemingly innocuous activities like photo editing. These apps might prompt users to upload personal photos, which could then be stored in unknown databases or used in ways the user did not intend. Parents must guide their children in using these applications cautiously, ensuring no personal information is visible in the background of photos or shared through the app.

AI chatbots, while useful, can sometimes provide content that is not age-appropriate. Imagine a scenario where a parent has installed an AI chatbot on their child's smartphone to assist with homework and answer educational questions. One day, the child decides to ask the chatbot a seemingly innocent question about birds. However, instead of receiving a child-friendly response, the chatbot generates inappropriate content related to adult topics or includes explicit language, causing the child to stumble upon content that is not age-appropriate.

In this example, the AI chatbot, though designed to be helpful, has failed to filter or moderate its responses properly, leading to a potentially harmful and inappropriate experience for the child.

The world of gaming and its hidden dangers

Gaming is a popular activity among children, with statistics showing that 91% of children in the UK aged 3-15 play digital games. This vast digital playground, however, also exposes them to potential attacks from cybercriminals. In 2022 alone, security solutions identified over seven million attacks related to popular children's games, marking a significant increase from the previous year. Games designed for younger children, such as Poppy Playtime and Toca Life World, were targeted.

The gaming environment often includes unmoderated voice and text chats, which can be a breeding ground for cybercriminals. These criminals can build virtual trust with young players, similar to how they would in person, by offering gifts or promises of friendship. Once trust is established, they can extract personal information, encourage clicking on phishing links, or even groom the children for more sinister purposes.

Moreover, when children can't find an app or game in their region, they might look for alternatives, which often turn out to be harmful copies. This danger exists even on trusted platforms like Google Play. Between 2020 and 2022, the research identified over 190 apps infected with the Harly Trojan on Google Play, secretly signing up users for paid services. The downloads of these apps are estimated at 4.8 million, but the real number of victims could be higher.

Both children and adults are vulnerable to this trend. Understanding cybersecurity basics is crucial. For instance, it's vital to examine the permissions an app seeks when you install it. Consider a basic flashlight app – it has no reason to request access to your text messages or camera. Being alert to these details is crucial for maintaining online security.

Fintech for kids: Opportunities and risks

One emerging trend is the development of financial products and services tailored for children as young as 12. These specialized offerings, such as bank cards and digital wallets designed for kids, present both promising opportunities and notable risks for young consumers and their parents.

Opportunities:

• Financial Education: Fintech products for kids can be powerful tools for teaching financial literacy from an early age. 
• Parental Control: Fintech solutions designed for children often come with built-in parental control features. These features allow parents to monitor their child's spending, set spending limits, and receive real-time notifications of transactions. 
• Digital Payments: In an increasingly cashless society, introducing children to digital payments and financial technology at a young age can help them adapt to the changing financial landscape.

Risks:

• Cybersecurity Threats: As fintech products for children gain popularity, they become attractive targets for cybercriminals. Cybersecurity risks include phishing scams, identity theft, and data breaches. 
• Social Engineering: Cybercriminals may use social engineering tactics to manipulate children into revealing sensitive information or making unauthorized transactions. 
• Financial Implications: While fintech products offer financial education opportunities, they also expose children to the risk of overspending or making unwise financial decisions. 

Navigating online privacy with growing children

As children mature, they develop a greater understanding of personal space and privacy, which extends to their online activities. With the internet becoming more accessible, children are increasingly conscious of these aspects. Therefore, when parents decide to install digital parenting apps on their children's devices, the reaction from the kids might not always be positive.

This situation necessitates that parents develop the ability to effectively communicate with their children about their online experiences and the significance of using digital parenting tools for their safety, while also respecting their personal space. It's important to set clear boundaries and explain the purpose of these apps to the children. Regularly checking in with them and modifying the app's restrictions as the child grows and becomes more responsible is also crucial for maintaining a healthy balance.

A quick note on smart home devices

As a final thought, to ensure that this article is comprehensive, it’s important to note that the rise of smart home devices has made life more convenient but also more vulnerable to cyberattacks. Children, who are often users of these devices, can unknowingly become targets for cybercriminals. For example, some security studies on a popular smart pet feeder uncovered serious vulnerabilities that could allow unauthorized access and data theft. Parents must ensure the security of these devices and educate their children on safe usage practices.

Final thoughts 

In conclusion, as technology continues to advance, so do the challenges and risks associated with its use, particularly for young users. Parents play a critical role in educating and protecting their children from these evolving cyber threats. By staying informed and engaging in regular discussions about online safety, parents can help ensure a safer digital environment for their children.

The technology of virtual reality, which has spread relatively recently, is rapidly evolving and gaining popularity. Manufacturing companies are actively developing and experimenting with this new technology. Virtual reality is used not only in the entertainment industry but also in science, education, medicine, architecture, and others. For cybercriminals, access to such data can become an attractive target.

At present, cases of hacking VR headsets and glasses are not widespread, but as virtual reality technologies develop and their popularity increases, it can be expected that such attacks will become more relevant for cybercriminals. Examples of cases may include vulnerabilities in the software of VR devices, which can be used for remote control or for collecting confidential information. In the future, with an increase in the number of VR technology users, the likelihood of such device hacks may increase.

VR technology

Virtual reality is a technology that allows users to immerse in a three-dimensional virtual world using technical means. A person can either simply observe another reality through glasses—watching 360-degree videos—or interact with it by playing games using controllers.

A full VR set includes a headset, controllers, and cameras. The headset creates the sensation that the player is in another reality—he or she can see and hear it. Motion sensors and accelerometers provide additional opportunities to fully immerse in the game. With controllers, one can perform actions and control their movements in the game, while cameras additionally collect information—reading the player's movements and warning if the player approaches set boundaries in real life, for example, a wall or furniture.

It's also important to highlight the capabilities of devices operating in augmented reality mode, where a person simultaneously sees both the good old "analog" world and virtual interfaces with which they can also interact.

Risks and information security threats when using VR

Cybercriminals may be interested in users' confidential data. By finding vulnerabilities in a VR application and hacking it, they can gain access to cameras and microphones.

Hacking VR headsets is a serious violation of users' privacy and security. Hackers can exploit vulnerabilities in the software or hardware of devices to access users' personal data, including location information, physiological parameters, and even video and audio recordings of virtual reality sessions. This can lead to various negative consequences, including theft of personal information, blackmail, privacy breaches, and even physical danger.

Cybercriminals can also deploy VR exploits to gain control over players' devices. In this case, they have access to the PC, can activate the microphone to eavesdrop, monitor user actions, and collect various information, including bank transactions, logins, and passwords.

If malicious software replicates itself, it can infect all visitors in a virtual room. This allows for collecting data about many people at once, monitoring their actions, encrypting files on their PCs, and then blackmailing them for ransom to restore access. When using a VR headset or set in business, hacking will have more serious consequences. A computer connected to a VR device becomes an entry point for cybercriminals into the corporate network.

Data protection and ensuring virtual reality security

To protect devices from hacking, it's necessary to understand the threat level and take security seriously. Here are some recommendations for protection. 

Regularly update the VR headset software to eliminate identified vulnerabilities and provide protection against new types of cyber threats. Connect only to secure Wi-Fi networks with data encryption (such as WPA2). Also, avoid open and unreliable networks to prevent interception of personal information.

It's important to protect access to the VR headset with a password or other authentication methods to prevent unauthorized access to the device. VR headset applications should be downloaded only from official stores to avoid installing malicious software. Finally, if possible, configure access rights to the device's data and functions to limit third-party applications' access to personal information. Following these measures will reduce the risk of cyber threats and ensure the safe use of VR headsets online.

Also important not to neglect updating your devices' software, as cybercriminals are constantly looking for new ways to access others' devices. Companies, in turn, promptly fix vulnerabilities in their products. For example, Apple released the first security patch fixing a zero-day vulnerability for Apple Vision Pro the day after journalists published reviews.

Conclusion

The use of virtual and augmented reality is rapidly evolving. New ways of applying it are found in various fields. There are not many cases related to the hacking of VR headsets and VR sets. However, experts predict an increase in attacks by cybercriminals in the future, proportional to the spread of VR technologies.

Using vulnerabilities in VR devices, cybercriminals can collect confidential data, record audio from microphones, and video from cameras, and even gain control over PCs and access corporate systems. To avoid this, it's necessary to take precautions: update software in time, not share access data with anyone, connect only through reliable Wi-Fi networks, and install VR applications only from official stores.

Neural networks are increasingly penetrating various spheres of our lives: from big data analysis, speech synthesis, and image creation to controlling autonomous vehicles and aircraft. In 2024, Tesla developers added neural network support for autopilot, AI has long been used in drone shows to form various figures and QR codes in the sky, and marketers and designers apply AI in their work to generate illustrations and text.

After the release of ChatGPT at the end of 2022 and its popularity, various companies have been actively developing their services based on GPT models. With the help of various services and AI-based Telegram bots, neural networks have become accessible to a wide range of users. However, if information security rules are not followed, the use of various services and neural networks involves certain risks. Let's discuss these in more detail.

Risks of using neural networks

The euphoria caused by the discovery of GPT chat for many people has been replaced by caution. With the emergence of numerous services based on language models, both free and paid, users have noticed that chatbots can provide unreliable or harmful information. Particularly dangerous is incorrect information regarding health, nutrition, and finances, as well as data on weapon manufacturing, drug distribution, and more. 

Moreover, the capabilities of neural networks are constantly expanding, and the latest versions can create remarkably believable fakes, synthesizing voice or video. Fraudsters use these features to deceive their victims by forging messages and calls from acquaintances and videos with famous personalities.

The main threat is the emerging trust many users have in neural networks and various chatbots in particular. Surrounded by an aura of accuracy and impartiality, people forget that neural networks can operate on fictional facts, provide inaccurate information, and generally make erroneous conclusions. It has been shown repeatedly that mistakes happen. If you ask frivolous questions, the damage will likely be minimal. But, if you use chatbots to resolve issues in finance or medicine, the consequences can be quite destructive. Moreover, often to get a response from a neural network, you must provide some data.

A big question is how this data will then be processed and stored. No one guarantees that the information about you that you included in the queries will not subsequently appear somewhere on the darknet or become the basis for a sophisticated phishing attack.

In March 2024, bug hunters at Offensive AI Lab, thanks to a data encryption feature in ChatGPT and Microsoft Copilot, found a way to decrypt and read intercepted responses. Regardless of how quickly OpenAI was able to patch this hole, its existence is a prime example of how malicious actors might use vulnerabilities in APIs to steal confidential data, including passwords or corporate information. In addition, vulnerabilities make it possible to conduct DDoS attacks on the system and bypass protection.

There are several types of attacks on AI, and it is important to be able to distinguish them. For example, evasion attacks (modification of input data) are potentially the most frequent. If the model requires input data for operation, it can be modified appropriately to disrupt the AI. On the other hand, data poisoning attacks have a long-term character. A Trojan present in the AI model remains even after it is retrained. All this can be combined into adversarial attacks – a way to deceive a neural network to produce an incorrect result.

Neural networks are still not sufficiently protected from attacks, data falsification, and interference in their operation for malicious purposes, so users should be vigilant and follow certain rules when working with chatbots.

Precautions and recommendations

The technology of large language models is rapidly developing, penetrating deeper into everyday life, and gaining more users. To protect yourself and your data from potential threats, it is important to adhere to some rules when working with neural networks:

• Do not share confidential information with chatbots;
• Download neural network applications and services from reliable sources;
• Verify the information provided by the chatbot.

Moreover, the main recommendation when working with public neural networks is not to assume that your dialogue with it is private. It's better to avoid a situation where the questions asked contain any private information about you or your company. The exception is if you are working with an isolated instance of a neural network, located in your environment and for which your company is responsible.

Also, carefully check the services through which you interact with the neural network. An unknown Telegram channel promising free work with all known LLM models definitely should not be trusted.

Companies, whose employees use neural networks at the workplace, should be especially cautious. The interest of malicious actors in corporate data is higher, and they hunt for sensitive organizational information first and foremost.

The best way to protect against cyber threats is to implement ongoing cybersecurity and AI training for employees. This is an important component of any work process, especially in Russia, where there is a shortage of qualified cybersecurity specialists. Only 3.5% fully meet the current requirements for a worker in this field. Through training, it is possible to improve specialists' skills and, consequently, reduce the number of attacks by more than 70%.

Additional measures should also be taken to enhance the overall IT security of the company. First of all, it is necessary to develop improved AI training algorithms considering its potential vulnerabilities, which will make the model more reliable by 87%. It is also necessary to "train" the neural network: to allow it to cope with artificially created cyber attacks to improve the algorithm's performance. This will help reduce the number of hacks by 84%. Moreover, it is necessary to constantly update the software to reduce the number of vulnerabilities by more than 90%.

Conclusion

Both businesses and ordinary users have already managed to "taste" the benefits of neural networks. In a large number of areas, they help solve everyday tasks and save effort and money. For example, generative neural networks have significantly affected the cost of producing movies, TV series, and other videos where graphics and processing are needed. At the same time, roughly the same neural networks have caused a wave of deep fakes, such as the new variation of the Fake Boss attack. 

Every user must understand that the neural network is vulnerable. Just like a messenger, mailbox, or work task planner – it can be hacked or subject to other failures, so it is important to approach working with it consciously.

Web browsers stand as gatekeepers of information, offering a semblance of privacy through a feature widely known as "Incognito mode." This mode, known variably as "Private" in Opera, "InPrivate" in Internet Explorer and Microsoft Edge, and simply "Incognito" in Google Chrome, suggests a veil of confidentiality. These names suggest a level of confidentiality, which can mislead some users about the actual capabilities of this mode. In this article, we have shed light on what Incognito mode really does, how it protects data, and how to maintain privacy online.

Understanding incognito mode

Incognito mode is a browser feature designed to hide certain online activities from other users of the same device. When activated, the browser stops saving:

• The history of search queries and visited pages;
• Cookies and site data;
• Information entered in forms;
• Passwords for autofill purposes.

Moreover, files downloaded while in Incognito mode won't appear in the device's download history. However, it's important to note that the websites you visit, your system administrator, and your internet service provider can still track your actions.

Myths surrounding incognito mode

One of the most pervasive myths about Incognito mode is its supposed ability to render users invisible to internet service providers (ISPs), governments, and malicious software. Contrary to popular belief, Incognito mode does not make one's online activities invisible to ISPs or shield against government surveillance. Nor does it offer any protection against viruses or malware. The mode merely ensures that the local browsing history, cookies, and site data are not stored on the user's device once the session is ended.

Another dangerous misconception is the belief that Incognito mode can protect users from all forms of online tracking. While it does prevent the storage of cookies and browsing history on the device, it does not hide the user's IP address or encrypt their internet traffic. Websites visited, as well as network administrators and ISPs, can still track online activities. This misunderstanding can lead users to overestimate the protection Incognito mode offers, potentially engaging in risky online behaviors under the false assumption of complete anonymity.

Appropriate uses for incognito mode

Despite its name, Incognito mode cannot guarantee complete privacy or data protection on the internet. Users should keep this in mind when using it. However, Incognito mode does offer several convenient features:

• It can keep your browsing interests hidden from family members or colleagues;
• It allows you to log into multiple accounts simultaneously by opening additional sessions in Incognito mode;
• It makes it harder for websites to collect information about your preferences for targeted advertising;
• It enables you to access your accounts on shared devices without leaving your account open to others. 

We recommend considering more reliable protection measures than just Incognito mode. If you're the sole user of your device, Incognito mode might not be particularly useful. Focusing on more effective measures such as antivirus protection, using a VPN, and controlling app permissions is advisable. If you're concerned about your data, consider regular backups and encryption.

Built-in VPNs and incognito mode

Some browsers offer built-in VPNs when using Incognito mode. Unfortunately, these are only partial measures that provide relative security for user information online. While Incognito mode can hide your browsing history within the browser, a built-in VPN might not be as reliable as a standalone application. For instance, a VPN provider can be hacked, or it might share user data with third parties. 

Free VPN services might collect user data for analytics or severely limit the performance of such solutions. It's also important to be wary of "dangerous" VPN servers that steal personal data, as they sit between the user and the web resource. Additionally, some VPNs may come bundled with malicious modules (e.g., miners) that financially benefit the VPN or browser owner at the expense of unsuspecting users.

Wrapping up – maintaining privacy online

For robust data protection and complete confidentiality, Incognito mode is insufficient. Additional tools are necessary. One solution for ensuring anonymity online is using a VPN from trusted vendors. A Virtual Private Network encrypts your data and hides your IP address. Other protective measures include:

• Using secure, up-to-date browsers;
• Installing and regularly updating antivirus software on your devices, as well as antivirus plugins for browsers to prevent visiting malicious sites and downloading suspicious files;
• Using complex and unique passwords for each account, along with two-factor authentication where possible;
• Exercising caution when opening and downloading files from unreliable sources to avoid malware;
• Only using VPN services from trusted vendors;
• Carefully reviewing the privacy policies of websites and services to understand how they handle user data.

Remember the importance of common sense and digital hygiene. Avoid downloading files indiscriminately, clicking on unknown links, or entering sensitive information on suspicious websites. While Incognito mode is a convenient feature, it's most effective when used correctly and with an understanding of its limitations.

Cybersecurity — as complex as it sounds — is an essential concept that we all need to be aware of in this day and age. Computers, phones, and smart devices have become an extension of our bodies at this point, which makes their security paramount. From your family photos to your bank details and social media handles, everything lives inside these devices. That’s why a security breach could have potentially life-changing consequences. With viruses and malware getting more advanced than ever, it’s no longer just a programmer’s job to care about cybersecurity. Every user should have at least a basic understanding of it to be able to implement it onto their devices. 

But, most of us aren’t too tech-savvy, so we can’t even understand the most basic computer terms. That’s why the first step is to get familiar with cybersecurity jargon so that you can easily grasp and follow tutorials online. In this article, we’re covering some of the most common cybersecurity terms and phrases. We’ve handpicked the most important ones, so read till the end and don’t miss any. Let’s get into it!

Phishing

Phishing is a malicious way to get unsuspecting users to click on shady links or attachments, or get them to reveal sensitive information by posing as a legitimate organization or business. Some attempts can be spotted easier than others depending on how sophisticated the setup is, and the user’s level of awareness.

Trojan

Sometimes, harmful code can be disguised as a legitimate program, application, or file, which is called a Trojan. 

Keylogger

A keylogger is a software tool that can monitor and record all keystrokes entered by a user. Through the data gathered by a keylogger, hackers can easily steal sensitive information like login details, credentials, OTPs (one-time passwords), private texts, and much more.

Account hijacking

Account hijacking is where a hacker takes control of a user’s account with malicious intent like stealing sensitive information or sharing problematic content through their platform. You could see it as a form of online identity theft, making it one of the biggest cybersecurity threats faced by celebrities and influential personalities.

DevSecOps

DevSecOps seem like gibberish at first glance, but it’s a combination of the words “development,” “security,” and “operations.”

The combined term refers to a software development approach that integrates security solutions into the development process right from the get-go. It’s ideal because, with cybersecurity threats, prevention really is better than cure. 

Digital footprint

As an online user, anything you do online creates a “footprint” consisting of your activities on the internet. For instance, what you post, what you like, the purchases you make, or simply the web pages you browse through. That’s your digital footprint. 

Cyber insurance

It’s a type of insurance that helps large organizations cover the risk of financial losses that may occur as a result of data breaches or cyberattacks.

Threat vector

Hackers or cyber attackers use a certain method or path to get into their target device, network, or system, referred to as the “threat vector.” 

IP address

An Internet Protocol (IP) address consists of a series of numbers associated with WiFi routers, servers, computers, and just about anything that’s connected to the Internet. Just like your standard home address, an IP address specifies the location of a system or device, letting users find it anywhere on the global network.

Malware

Malware is one of the most common words used within the cybersecurity space. It’s short for “malicious software,” and can be any code that’s meant to cause harm to systems or computers. Depending on how dangerous it is, it can steal, delete, and spy on information, or even destroy a system altogether.

Virus

A computer virus is a specific type of malware that’s designed to corrupt, change, or delete information from a system. Like viral diseases, a computer virus also passes onto other systems through in-built multiplication means like sending out emails with malware as attachments, etc. 

Antivirus software

Antivirus software, as the name suggests, is a computer program that’s responsible for preventing, detecting, and getting rid of malware. Getting a strong antivirus service for your Mac or Windows PC is the most important step you can take to reinforce your cybersecurity defenses as an average user.

VPN

Most of us already know or use VPNs, without ever even knowing what it stands for. It’s an acronym for “Virtual Private Network,” whereby the user’s actual IP address gets replaced by the VPN’s — granting them digital anonymity and making a cyber attacker’s life much harder. 

Cryptojacking

Cryptojacking is another modern threat for unsuspecting users where hackers can start using your computer’s processing power to mine cryptocurrency in an unauthorized manner. This slows down performance and starts jacking up your utility bills while the user has no clue.  

Data encryption

Data encryption is the process of encoding data such that no third party can access it unless they have a decryption key. 

Data protection

Data protection is an umbrella term that consists of many different practices designed to prevent private info from getting exposed to the wrong eyes. Data encryption, for instance, is one of the examples of data protection. 

DDoS attacks

Distributed Denial of Service (DDoS) is a method used by attackers to render a server or site unusable. It involves overwhelming it with bots or malicious traffic in volumes that are way over the capacity it’s meant to handle.

Worm

A worm is a particularly nasty type of malware that can reproduce itself just to spread to other networks and computers. They can either slow down the computer by compromising its resources or steal data.

Conclusion

Now that you know some of the most commonly used cybersecurity jargon, you can hopefully start to educate yourself on this crucial topic. This vocabulary should allow you to comprehend basic cybersecurity tutorials to perform regular tasks like installing an antivirus program, performing a scan, and quarantining or removing threats from your computer. All the best!

The issue of data residency is becoming increasingly critical in 2024, especially concerning data stored in cloud environments. 

This concern is primarily driven by stringent data protection frameworks like the General Data Protection Regulation (GDPR), which mandates strict guidelines for handling personal data within the European Union and European Economic Area. 

The GDPR has necessitated a comprehensive reassessment of how organizations manage, protect, and govern personal data, underscoring the need for robust and dynamic data governance practices.

Let’s take a closer look. 

The global Impact of GDPR and beyond

The introduction of the GDPR has catalyzed a global movement toward stronger data privacy protections. Countries across the globe, including Australia, Brazil, Canada, Japan, South Africa, and the UAE, have responded by enacting their data protection laws. This worldwide legislative trend highlights a growing consensus on the importance of data privacy, reflecting an international commitment to safeguarding personal information against misuse and breaches in the digital era.

The consequences of failing to comply with data protection regulations are severe, with the potential for substantial financial penalties and reputational damage. The case of Meta, Facebook's parent company, being fined $1.3 billion by the EU for GDPR violations in May 2023, exemplifies the tangible risks organizations face. This incident not only underscores the financial implications of non-compliance but also highlights the broader reputational risks, emphasizing the critical need for stringent adherence to data privacy standards.

Concepts of data residency 

Ultimately, the idea of Data Residency involves the physical or geographical location of data, with legal mandates often requiring that data be stored within the country or region of its collection to comply with local privacy laws. However, there are two further definitions to consider. 

Data localization
Extending beyond residency, data localization imposes stricter controls on data, mandating that it remains within a specific jurisdiction. This approach reflects a desire for greater control over data movement and access, aiming to enhance data security and sovereignty.

Data sovereignty
This aspect focuses on the governance of data based on the laws of the country where it is stored and processed. Data sovereignty emphasizes the principle of national authority and control over data, highlighting the legal complexities and challenges of international data management.

Navigating cloud computing challenges in depth

The advent of cloud computing has revolutionized the way organizations store, process, and manage data. However, this revolution brings with it specific challenges, particularly when it comes to ensuring data residency. The dynamic and distributed nature of cloud services, while offering unprecedented flexibility and scalability, introduces complexities in adhering to data residency, localization, and sovereignty policies. The essence of cloud computing—its ability to seamlessly scale and distribute resources across geographical boundaries—stands in contrast to the rigid requirements of data residency regulations.

Moreover, the diversity in cloud deployment models adds another layer of complexity. Public clouds, offering services over the Internet, present challenges in controlling where data is stored and processed. Private clouds, operated solely for a single organization, offer greater control but require significant investment and expertise to manage effectively. Hybrid clouds, combining elements of both public and private clouds, offer flexibility but necessitate sophisticated strategies to manage data residency effectively. Each model presents unique risks and considerations for data security, from the potential for unauthorized access.

In this context, our company, Passwork, offers a self-hosted solution that addresses these challenges head-on. By providing a secure, self-hosted password management system, Passwork enables organizations to maintain complete control over their data, ensuring that it resides within their infrastructure. This approach not only aligns with data residency, localization, and sovereignty requirements but also enhances data security by keeping sensitive information out of third-party hands. 

Our solution is designed to meet the needs of businesses seeking to navigate the complexities of data protection in the cloud era, offering peace of mind through enhanced control and security. 

The pivotal role of Data Security Posture Management (DSPM) platforms

In the quest for robust data residency compliance, Data Security Posture Management (DSPM) platforms have emerged as indispensable tools. These platforms offer unparalleled capabilities for the continuous monitoring, detection, and management of data across cloud environments. With DSPM platforms, organizations gain detailed visibility into the location, movement, and activities associated with their data, enabling them to effectively navigate the complexities of data protection regulations.

DSPM platforms are instrumental in the proactive identification and classification of sensitive data, facilitating the implementation of appropriate protection measures. By leveraging these platforms, organizations can ensure that they are not only compliant with current data protection regulations but are also prepared to adapt to future changes in the regulatory landscape. The ability of DSPM platforms to provide real-time insights and alerts about potential risks and vulnerabilities is invaluable, enabling organizations to address compliance issues swiftly.

Conclusion

As we move forward in the digital age, the importance of data protection and privacy continues to grow. 

Organizations worldwide must recognize the critical need for effective data management and protection strategies, including the adoption of advanced technologies like DSPM platforms. By embracing these strategies, organizations can not only ensure compliance with international data protection standards but also protect sensitive information, maintain their reputational integrity, and avoid significant financial and legal repercussions. 

The journey toward global data privacy is ongoing, and it requires a committed, proactive approach to navigate the challenges and opportunities it presents.

Many users today worry about their private information being stolen or misused, whether by cybercriminals hacking into databases or government agencies reading personal messages. 

Yet, despite these fears, people often voluntarily leave a significant digital footprint online by sharing sensitive information through social media posts, filling out forms, and agreeing to data processing terms without a second thought. 

This behavior, while seemingly harmless, can lead to various consequences, from minor annoyances like spam calls to more invasive disruptions such as persistent targeted ads.

In this article, we will explore what kind of data is being collected, who is collecting it, how it is done, and why this practice has become so widespread.

Who collects your data and why

In today’s data-driven world, information, especially user data, has become a highly valuable resource. Companies and organizations use it to make informed decisions, and, in many cases, monetize it. 

This data includes not just credit card numbers or sensitive financial details but also more seemingly innocuous information, such as your age, relationship status, interests, and even your location. 

Companies use this information to better promote their products and services, tailoring advertisements to match your specific interests. In contrast, scammers use this data to refine their fraudulent activities, targeting individuals more accurately based on their online behavior and preferences.

From the user’s point of view, the collection of this data is often seen as the price of using free services. It's important to recognize that free online platforms generally stay afloat through advertising revenue, which depends heavily on reaching the right audience. 

Without web analytics, companies wouldn’t be able to tailor their content and offerings effectively, which is why data collection has become so integral to their business models. 

That said, many users don't fully grasp the risks of their data being stolen or misused. While it might seem that leaking data on your browsing history or online shopping habits poses little risk, even this seemingly unimportant information can be used against you. For example, it could make you a target for phishing schemes or other forms of cyberattacks.

Entities collecting user data can include:

• Browsers and websites: Using cookies, tracking tools, and local storage to gather data on your browsing habits, preferences, and interactions. This data helps improve user experience and allows companies to personalize advertising content.
• Government agencies: They may collect data for purposes like national security, law enforcement, or monitoring for potential threats. Often, this involves social media monitoring and large-scale data analysis.
• Private companies: Firms track user behavior to better understand consumer preferences, enabling them to offer targeted ads and refine their marketing strategies.
• Cybercriminals: Through illegal methods such as phishing, criminals can gather sensitive data to carry out fraud, identity theft, or other illicit activities.

Data is collected for various reasons, ranging from enhancing service convenience to outright breaches of privacy. Being aware of what data is collected and how it's used can help minimize risks and safeguard personal information.

How data Is collected

The internet is an open source of information, and much of your personal data can be collected from publicly available platforms like social media profiles, professional websites, and online forms. Even without explicitly sharing sensitive information, companies and malicious actors can build a detailed profile of your interests, habits, and identity based on the digital trail you leave behind. 

Analytics services and web tracking tools monitor your online activities, from the websites you visit to the products you search for or purchase.

Companies use various tools to gather user data, including:

• Web analytics platforms such as Google Analytics, which offer detailed insights into user behavior on websites.
• Customer Relationship Management (CRM) systems, which store and analyze customer data to better manage business-client relationships.
• Social media analytics, which track user interactions like likes, comments, and follows to build an understanding of user interests.
• Feedback mechanisms, such as reviews, surveys, and polls, that provide direct information from users about their preferences and satisfaction levels.

These tools enable companies to refine their products and services, ensuring they meet consumer demands while simultaneously improving the effectiveness of their marketing strategies.

Risks and threats

While marketing tools are generally used to create personalized ads and improve service quality, there are risks associated with data collection.

• Privacy concerns: Even anonymized data carries the risk of being de-anonymized.
• Data security: Companies must protect user data from leaks and cyberattacks.
• Purpose of data use: Users may be unaware of how their data will be used, leading to potential misuse.

For instance, in 2018, Telegram agreed to share user data with authorities if users were suspected of terrorism. Additionally, users can lose control over how their personal data is used, which could lead to spam, unwanted calls, or more serious consequences like identity theft or account fraud.

Final thoughts

Practicing good digital hygiene is crucial in reducing the risks of personal data collection. Users should carefully review the privacy policies of websites and apps they use and limit sharing personal information to trusted platforms.

Legally, data collection on the internet must comply with strict regulations concerning personal data protection. Companies should publish privacy policies, seek user consent for data processing, and adhere to rules on data usage and sharing. In turn, users have the right to know how their data is used and to control its processing.

The distribution of malware alongside cracked games or applications is one of the oldest tricks in the cybercriminal playbook. Surprisingly, even in 2024, there are still naive victims who believe in modern-day Robin Hood and assume that downloading cracked paid programs and games from pirate sites is perfectly safe. However, while this threat is old, criminals continuously invent new methods to deliver malware to the victim's computer to bypass security solutions.

A recent campaign of this kind was discovered targeting Apple computers with the latest versions of macOS (13.6 and above), utilizing the features of the Domain Name System (DNS) service to download malicious payloads. Victims are offered free downloads of cracked versions of popular applications. 

But what awaits those who succumb to temptation?

Fake activation

After downloading a disk image supposedly containing a cracked program, the victim is prompted to copy two files into the Applications folder: the application itself and an "activator" program. If only the application is copied and launched, it will not work. The instructions state that the cracked program must be "activated”. Analysis revealed that the activator's function is primitive—it removes a few initial bytes in the application's executable file, after which the application starts working. Essentially, the criminals took an already cracked application and modified it so that it could not be launched without the activator. Of course, the activator has an unpleasant additional function—upon launch, it requests administrator rights and, using them, installs a script loader in the system. This script downloads additional malicious payloads from the Internet—a backdoor that regularly requests commands from criminals.

Connection through DNS

To download the malicious script, the activator turns to a rather exotic and innocently appearing tool—the Domain Name System (DNS). It has an interesting technical feature. Each DNS record not only links the internet name of a server to its IP address but can also contain an arbitrary textual description of the server, known as a TXT record. The criminals exploited this by placing fragments of malicious code in TXT records. The activator downloads three TXT records from a malicious domain and assembles them into a ready script.

This seemingly complex scheme has several advantages. First, the activator does nothing particularly suspicious—accessing DNS records is a common activity for any internet application, and it is a necessary first step for any communication session. Second, by changing the domain's TXT records, criminals can easily update the script to modify the infection scheme and the final malicious payload. Third, removing malicious content from the network is not so simple due to the distributed structure of the domain name service. For internet providers and companies, it's even difficult to notice a policy violation, as each such TXT record is only a fragment of malicious code, which in itself does not pose a threat.

The final round

Thanks to the periodically launched script downloading scenario, criminals can update the malicious payload and perform any actions they need on the victim's computer. At the time of our analysis, they were interested in stealing cryptocurrency. The backdoor automatically searches the victim's computer for Exodus or Bitcoin wallets and replaces their applications with trojanized versions. The infected Exodus wallet steals the key phrase (seed phrase), and the infected Bitcoin wallet steals the encryption key that encrypts the private keys, allowing the attackers to sign transfers on behalf of the victim. Thus, by "saving" a few dozen dollars on cracked applications, one can lose an order of magnitude more in crypto.

Other famous cases of cryptocurrency hacking

One of the most high-profile cases in the history of cryptocurrencies is the 2014 hack of the Mt. Gox exchange, which resulted in the theft of around 850,000 Bitcoin. This incident highlighted the importance of cryptocurrency exchange security and led to stricter security measures in the industry. The Mt. Gox hack showed that even the largest platforms are not immune to attacks and that the importance of storing cryptocurrency in a secure wallet cannot be overstated.

Another famous case is the DAO (Decentralised Autonomous Organisation) hack in 2016 when over $50 million in Ether was stolen due to a vulnerability in a smart contract. This case highlighted the risks associated with technological innovation and the need for careful auditing of smart contract codes.

How to protect yourself from an attack on your crypto wallet

Let's state the obvious: to avoid the threat and not become a victim of criminals, download applications only from official app stores. If you want to download an application from the developer's site, ensure you are on the real site, not one of the many fake sites. If you are thinking about downloading a cracked version of an application—think again. "Honest and trustworthy" sites with pirated products are as rare as unicorns and elves.

It is also worth applying these safety measures:

• Cold storage. Storing cryptocurrency in a wallet that is not connected to the internet is considered one of the most secure methods of protection. Cold wallets can be in the form of hardware devices or paper wallets.
• Two-factor authentication. (2FA): Using 2FA to access cryptocurrency wallets and exchanges greatly increases security by adding an extra layer of verification.
• Regular security audits. Regular security audits and software updates for wallets and exchanges help identify and address vulnerabilities.
• Education and awareness. Understanding basic cybersecurity principles and being aware of current threats helps prevent many attacks.

These protections, while not guaranteeing complete security, greatly reduce the risk of losing your cryptocurrency to hacker attacks or fraud. It is important to remember that in the world of cryptocurrencies, security must come first, and every user is responsible for protecting their investment.

Every year, billions of people go to the polls to determine their next political leaders. The results of elections around the world, from India to the United States to Europe, shape the geopolitical situation for years to come. Cybercriminals love to exploit important and large-scale events, and elections are no exception.

With every election, there are warnings about disinformation, deep fakes created by artificial intelligence, and possible interference in the electoral process in different countries. However, not only are government agencies and political parties targets, but millions of voters also actively read political news and discuss hot topics online.

This article examines the multifaceted goals of election cyberattacks. 

Goals of cyber attacks during elections

One of the primary objectives of cyber attacks during elections is to manipulate public perception. Disinformation campaigns, spearheaded by state-sponsored actors or independent hacker groups, aim to sow discord and confusion among the electorate. These campaigns often employ social media platforms to spread false information, create fake news, and amplify divisive narratives.

During the 2017 French Presidential Election, hackers leaked a trove of emails from Emmanuel Macron's campaign just days before the election. The data breach, known as "MacronLeaks," involved the theft and public release of thousands of internal documents. While the attack did not ultimately alter the election outcome, it demonstrated the potential for cyber espionage to disrupt and influence electoral processes.

Beyond shaping public opinion, cyber attackers often target the technical infrastructure that supports elections. This can include voter registration databases, voting machines, and election management systems. The goal here is to disrupt the electoral process, either by causing delays, creating confusion, or directly altering vote counts.

Cyber attackers frequently aim to steal sensitive information during elections. This information can include voter data, internal communications of political parties, or confidential documents. The stolen data can then be used for various purposes, such as blackmail, further disinformation, or direct financial gain.

Another significant goal of election-related cyber attacks is to undermine voter confidence in the electoral system. By creating a perception of insecurity and vulnerability, attackers aim to diminish public trust in the legitimacy of election results. This can lead to lower voter turnout, increased skepticism towards elected officials, and overall democratic destabilization.

In some cases, the explicit aim of cyber attacks during elections is to directly influence the outcome. This can involve hacking into voting systems to alter vote counts or manipulating voter registration databases to disenfranchise specific groups of voters.

Cyber attacks during elections can also target political campaigns themselves. By hacking campaign websites, stealing sensitive strategy documents, or launching denial-of-service attacks, malicious actors aim to disrupt the operations and effectiveness of political campaigns.

Lastly, cyber attacks during elections can serve broader economic and geopolitical objectives. By destabilizing a rival nation's political landscape, state-sponsored attackers can gain strategic advantages. This can involve weakening the targeted nation's international standing, creating favorable conditions for economic negotiations, or simply asserting dominance in the cyber domain.

Combating cyber attacks on elections

To combat these multifaceted threats, governments and organizations worldwide have implemented a range of strategies and technologies. Here are some key measures:

Strengthening cybersecurity infrastructure
Investing in robust cybersecurity infrastructure is critical. This includes deploying advanced intrusion detection systems, encrypting sensitive data, and regularly updating software to patch vulnerabilities. Many countries have established dedicated cybersecurity agencies to oversee these efforts. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) plays a crucial role in protecting election infrastructure. CISA collaborates with state and local election officials to provide guidance, resources, and real-time threat intelligence. By fostering partnerships and promoting best practices, CISA helps bolster the resilience of election systems.

Enhancing public awareness
Educating the public about the tactics used in disinformation campaigns is vital. Media literacy programs and public awareness campaigns can help voters identify false information and reduce the impact of manipulative content.

International cooperation
Cyber threats often transcend national borders, making international cooperation essential. Sharing intelligence, collaborating on cybersecurity research, and developing common frameworks for election security are crucial steps in addressing the global nature of these threats. The European Union Agency for Cybersecurity (ENISA) works to enhance the cybersecurity capabilities of EU member states. ENISA provides expertise, conducts training exercises, and facilitates cooperation among nations to improve the security of electoral processes across Europe.

Implementing auditable voting systems and promoting transparency
Adopting voting systems that provide a verifiable paper trail can help ensure the integrity of election results. Post-election audits can detect and address any discrepancies, bolstering public confidence in the electoral process. Transparency in the electoral process is essential to maintaining public trust. Governments and election officials should communicate openly about the measures in place to secure elections and the steps taken to address any incidents. Estonia is a pioneer in digital voting, having implemented a secure online voting system since 2005. The system uses advanced encryption and authentication methods to ensure the security and integrity of votes. Additionally, Estonia provides transparency through public access to audit logs and extensive voter education.

Final thoughts 

Cyber attacks during elections are a real threat to democratic processes worldwide. Understanding the diverse objectives of malicious actors, from manipulating public perception to disrupting electoral infrastructure, is crucial for developing effective defenses.

By strengthening cybersecurity infrastructure, enhancing public awareness, fostering international cooperation, implementing auditable voting systems, and promoting transparency, we can better protect the integrity of elections. As technology continues to advance, so too must our strategies to safeguard our most fundamental democratic processes from cyber threats.

If you have access to the internet, you’ve likely heard about “Hamster Kombat,” a game that has caused quite a stir worldwide. Alongside its not-so-obvious financial prospects and the risk of wasting your time, there are significant cybersecurity risks to be aware of. This article delves into the cybersecurity risks that users of Hamster Kombat and similar clicker games face.

What are clicker games and what makes them unique?

Clicker games, also known as incremental games, revolve around the repetitive action of tapping the screen to earn in-game currency. The coins you collect can be spent on upgrades that speed up the earning process or even automate it entirely. When the game runs in the background without any player input, it is often referred to as an “idle game.” These games are designed for endless progression and level advancement without demanding constant attention.

The appeal of clicker games dates back to 2013, when they first captured the public’s interest due to their simplicity and ability to provide a welcome distraction from daily life. Fast forward to 2024, and we see the resurgence of this genre with the introduction of Hamster Kombat, popularly known as the “hamster game.” 

The creators promised that the in-game currency could eventually be exchanged for real money once the Hamster Kombat coin was listed on a cryptocurrency exchange. Other clicker games like Yescoin, Blum, TapSwap, BIRD, 1WIN Token, and MemeFI have also emerged, each offering potential earning opportunities.

The risks faced

One of the main risks is phishing by the developers of clicker games. There have been instances where individuals join such projects and are asked to authenticate on phishing sites to “verify their Telegram account.” This can compromise the user’s Telegram account, exposing personal conversations and potentially leading to further phishing campaigns. For example, the compromised account could be used to send phishing links to all contacts.

In some projects, users are asked to enter their seed phrase to recover access to their cryptocurrency wallet. This is often presented as necessary for linking the wallet and withdrawing cryptocurrency. Unfortunately, this results in users losing all the cryptocurrency stored in the compromised wallet.

Another risk involves installing malicious software disguised as tasks or upgrades for the game account. Users may be prompted to “install an app on your smartphone to mine 30% more coins.” 

Such software can compromise the security of the user’s device, leading to data theft or unauthorized access to personal information.

In the least harmful scenarios, fraudulent projects result in wasted time and pointless task completion. Players receive no payments, while scammers profit from their subscriptions to external Telegram channels.An illustrative example is Hamster Kombat, where a hacker claimed to have exploited a vulnerability. By manipulating the game’s web version on Telegram, the hacker was able to earn all the in-game currency instantly by inputting the desired values into the browser console. This exploit highlights the importance of robust security measures and the potential risks associated with online games.

Information security threats in mobile gaming

Mobile gaming is not immune to cyber threats. There are several ways cybercriminals can attack users, categorized into risks related to users and those associated with irresponsible developers.

User-related risks include phishing, social engineering, malware, and client-side attacks. Phishing involves tricking users into divulging personal information by pretending to be a legitimate service. Social engineering manipulates users into performing actions or sharing confidential information. Malware can be introduced through malicious apps or updates, compromising the device’s security. Client-side attacks exploit vulnerabilities in the user’s device or applications.

Developer-related risks involve non-compliance with information security standards, unethical data collection, lack of security updates, exploitation of known vulnerabilities, and selling user data to third-party companies. 

Indeed, developers may not adhere to industry standards for data protection, leading to vulnerabilities. Unethical data collection practices can result in excessive user data being harvested and sold. A lack of security updates can leave applications vulnerable to attacks. 

Known vulnerabilities may be exploited if not addressed promptly, and user data may be sold without consent.

Additionally, game developers themselves may be dishonest and share user data with third parties. Popular games attracting hundreds of thousands of users are an enticing target for cybercriminals.

How to protect yourself

Using strong passwords is a fundamental step in protecting your online accounts. Ensure your passwords are complex and unique to each account, making them harder to guess or crack.

Enabling two-factor authentication (2FA) provides an additional layer of security. Where possible, enable 2FA for your accounts. This adds a second step to the login process, typically involving a code sent to your phone or email, making it more difficult for unauthorized users to gain access.

Avoiding suspicious links and offers is crucial. Be cautious of links and offers that seem too good to be true. These can often be phishing attempts designed to steal your personal information or credentials. Regularly updating your operating system and apps is essential for mitigating known vulnerabilities. Software updates often include security patches that protect against the latest threats. Ensure your devices and applications are always up to date.

Verifying the authenticity of requests for personal information or credentials can prevent phishing attacks. Always double-check the source of such requests and ensure they are legitimate before providing any information. Installing reliable antivirus software can help detect and prevent malware infections. Choose a reputable antivirus solution and keep it updated to protect your device from malicious software.

Additional cybersecurity measures

Using a Virtual Private Network (VPN) can add a layer of security by masking your IP address and encrypting your internet connection, making it harder for cybercriminals to track your online activities. VPNs are especially useful when accessing public Wi-Fi networks, which are often less secure.

Regularly backing up your data ensures that you have copies of your important information in case of a cyber attack or data loss incident. Store backups in a secure location, separate from your main devices, to protect against ransomware and other threats.

Always use secure, encrypted connections (HTTPS) when entering personal information online to protect your data from being intercepted. Check for the padlock icon in the address bar to ensure the connection is secure.

Staying informed about the latest cybersecurity threats and how to counter them is crucial. Participate in cybersecurity training and stay updated with reliable sources of cybersecurity news. Knowledge is a powerful tool in protecting yourself from cyber threats. Regularly monitor your accounts for any suspicious activity. Early detection can help mitigate the damage caused by unauthorized access. Set up alerts for unusual account activity and review your account statements regularly.

The future of clicker games and cybersecurity

As clicker games continue to evolve, so will the methods used by cybercriminals. Developers and players alike must remain vigilant and adopt robust security practices. The integration of blockchain technology in these games presents new opportunities and challenges. While blockchain can enhance security through decentralized and transparent processes, it also introduces complexities that require careful management.

One emerging trend is the use of smart contracts in blockchain-based games. Smart contracts can automate and secure transactions, but they are also susceptible to vulnerabilities if not properly coded. Ensuring that smart contracts are audited by cybersecurity experts is essential to prevent exploits.

Final thoughts 

Clicker games, while entertaining, come with a variety of cybersecurity risks. Users must remain vigilant and practice good cybersecurity hygiene to protect their personal information and devices. By being aware of these risks and taking proactive measures, players can enjoy these games without compromising their security.

Wi-Fi networks have seamlessly integrated into our lives, becoming as commonplace and expected as electricity flowing through an outlet. They're found everywhere: in homes, cafes, shopping centers, offices, public transport, and even in nature, with our phones often serving as personal hotspots. However, it's easy to overlook that Wi-Fi networks can be a vulnerable point through which cybercriminals might gain access to our devices.

In the context of home Wi-Fi, attackers often aim for personal data such as passwords, banking details, or personal information. Moreover, compromised home Wi-Fi networks can be leveraged for illicit online activities, including downloading pirated content or launching cyberattacks against other systems.

For business Wi-Fi networks, the stakes are higher. Attackers might target confidential corporate information, including financial records, customer data, or proprietary secrets, potentially disrupting business operations. Such breaches can lead to significant consequences, including data leaks, financial losses, or damage to the company's reputation.

The process of Wi-Fi hacking

Wi-Fi hacking can be as simple as a neighbor or someone in a nearby office building not wanting to pay for their internet and attempting to use someone else's. Their goal isn't necessarily malicious; often, they just need the router's password, which can be obtained using specialized hacking software. It's important to note that accessing a network without permission is illegal, and such software should only be used for testing the security of one's own network.

Wi-Fi hacking tools typically employ a brute force attack, trying every possible combination of letters and numbers to crack the password. The complexity of the password directly affects the time required to breach it.

In homes, routers connect a wide array of devices, making them a prime target for hackers. Gaining access to a router can open up numerous possibilities for malicious activities, such as data theft, surveillance, or even using the devices for DDoS attacks or covert cryptocurrency mining.

If direct password cracking fails, attackers might exploit security protocol vulnerabilities or create fake access points. For instance, vulnerabilities in WPA-2 security technology were exploited using Key Reinstallation Attacks (KRACK), and in 2024, new vulnerabilities were discovered in Wpa_supplicant software and the iNet Wireless Daemon (IWD).

Another method to gain network access involves social engineering, such as asking for the Wi-Fi password by pretending to be a client or employee.

Identifying a compromised network

The challenge of detecting a hacked network varies significantly between home and corporate environments due to the scale and complexity of the networks involved. For home networks, signs of unauthorized access can often be quite apparent. A sudden decrease in internet speed can indicate that outsiders are consuming bandwidth. Additionally, unfamiliar devices appearing in the router's connected devices list is a telltale sign of a security breach. These indicators are relatively easy to monitor and can quickly alert homeowners to potential security issues.

Corporate networks, however, present a more complex challenge. The sheer volume of devices and the breadth of network activity can obscure the signs of unauthorized access. Yet, there are nuanced indicators that IT professionals can monitor. Unexpected software installations can be a red flag, especially if the new software is unknown or unauthorized by the company's IT department. Similarly, unusual spikes in network traffic or abnormal data flows can indicate that an intruder is siphoning data or exploiting the network for malicious purposes. Monitoring for these signs requires a sophisticated approach, often involving advanced network monitoring tools and a keen understanding of normal network behavior to spot anomalies.

Fortifying Wi-Fi security: strategies and best practices

The first line of defense in network security is the router, serving as the gateway between the internet and the devices on the network. The market offers a wide range of routers, from basic models suitable for home use to advanced routers designed for the complex needs of businesses. The choice of router should be informed by the specific needs and security requirements of the user or organization.

For home networks, security experts advise against the complacency of sticking with the default settings provided by the router manufacturer. One of the simplest yet most effective security measures is changing the default password to a complex, unique one. This step alone can thwart a significant number of unauthorized access attempts. Renaming the network SSID to something generic that doesn't reveal personal information or the router model can also deter potential attackers. Additionally, disabling network discovery and enabling MAC address filtering can further secure the network by making it invisible to casual scans and ensuring that only devices with approved MAC addresses can connect.

Corporate networks require a more layered approach to security, given the higher stakes involved. Routers with advanced security features that can be integrated into a broader security framework are essential. These routers often come with the capability for regular security updates and can be configured to work with Security Incident and Event Management (SIEM) systems, providing real-time monitoring and analysis of security alerts generated by network hardware and applications. For businesses, the security of the router and the network it supports is not just about protecting data; it's also about safeguarding the company's reputation and financial well-being.

Beyond the technical configurations, both home users and businesses must adopt a proactive stance on network security. This includes staying informed about the latest security threats and trends, regularly updating router firmware and network security software, and educating all users about the importance of security practices such as using strong passwords and recognizing phishing attempts.

Conclusion

In 2024, the importance of securing our Wi-Fi networks cannot be overstated. The convenience and connectivity offered by these networks come with inherent risks, making them prime targets for cybercriminals. By understanding the methods employed by hackers and implementing robust security measures, individuals and businesses can significantly mitigate the risks associated with Wi-Fi usage. In the end, the key to safeguarding our digital domains lies in a combination of advanced technology, vigilant monitoring, and an unwavering commitment to cybersecurity.

In May 2024, Microsoft introduced a new feature for Windows 11 called Recall. This feature allows users to "remember" everything they've done on their computer over the past few months. 

By typing general queries like "photo of the red car someone sent me" or "which Korean restaurant was recommended" into the search bar, users receive results that include links to applications, websites, or documents, along with thumbnail images of their computer screen at the moment they viewed the subject of the query.

How Recall works

To enable this advanced search, Recall takes screenshots of the entire screen every few seconds and saves them in a folder on the computer. These images are then analyzed by AI in the background, extracting information and storing it in a database, which is used for intelligent searches by the AI assistant.

Security concerns

Despite being performed locally on the user's computer, Recall has raised significant security concerns. Initially, the implementation of Recall was barely encrypted and accessible to any computer user. 

Under pressure from the cybersecurity community, Microsoft announced improvements to Recall before its public release, now delayed to late autumn 2024. However, even with promised enhancements, the feature remains controversial.

The risks of Recall

One of the primary risks of Recall is the aggregation of all sensitive data—medical diagnoses, password-protected conversations, bank statements, and private photos—in one place on the computer.

If an unauthorized person gains access or the machine is infected with malware, all this critical information can be stolen by copying a single folder. While stealing screenshots is more challenging due to their volume, the text-based information can be exfiltrated in seconds.

If an attacker manages to extract the database with screenshots, they can almost second-by-second reconstruct everything the user has done on their computer over the past few months. Recall can save up to 3 months of history if the allocated space (default is 10% of the storage, up to 150 GB) is not filled sooner.

The initial version of Recall stored screenshots and the database in an unencrypted format. Cybersecurity experts demonstrated how to bypass OS restrictions and access Recall's databases and screenshots. To address this, Microsoft promises to encrypt the databases and decrypt them "on the fly." However, the effectiveness of this implementation remains unverified, and decryption on the local computer may be straightforward.

Microsoft notes that passwords, financial data, and other sensitive information displayed on the screen will be saved in Recall's database. If Recall is not paused, only private windows in browsers like MS Edge, Chrome, Opera, or Firefox and DRM-protected data are excluded. Recovery codes, disappearing messages, or deleted emails will remain in the database, visible to anyone with access to the unlocked computer.

Managing Recall risks

Users who frequently store sensitive information, are legally required to protect work data, share their computer, suffer from aggressive monitoring, or find AI search unhelpful should disable Recall entirely. Opening settings can do this, navigating to Privacy & Security -> Recall & Snapshots, disabling Save Snapshots, and clicking Delete All to remove previously saved snapshots.

For users who don't want to disable Recall, it's crucial to configure it properly. Exclude applications and websites where sensitive information is viewed, such as banking sites, government services, insurance and medical organizations, password managers, work-related apps, and cryptocurrency-related sites.

Ensure comprehensive cybersecurity protection is installed, as specialized malware could steal months of activity history. Consider:

• Enabling Bitlocker full-disk encryption.
• Protecting accounts with strong passwords and biometric access.
• Setting up and using screen lock when away from the computer.
• Creating separate accounts or using guest accounts for other users.

Additional considerations

Recall's comprehensive data collection can significantly impact personal privacy. For individuals in challenging situations, such as dealing with overbearing managers or overly curious household members, the detailed activity logs provided by Recall can be particularly concerning. They might be used to track work efficiency, personal communications, and even personal movements over time, leading to potential misuse of sensitive information.

The very features that make Recall useful also make it a potential goldmine for cybercriminals. If cyber attackers gain access to Recall's data, they can gather extensive information about a user's activities, preferences, and sensitive data. This could lead to targeted phishing attacks, identity theft, and other forms of cybercrime. Moreover, the ability to reconstruct a user's activity timeline could be exploited for blackmail or surveillance purposes.

Initially, Microsoft intended for Recall to be enabled by default. However, public pressure led to a change, and now users must opt-in during Windows setup. This opt-in approach gives users control over whether they want to use Recall, but those receiving pre-configured systems, such as from workplaces, should check and manage Recall's settings themselves.

Currently, Microsoft states that Recall will be available only on Copilot+ computers equipped with a special NPU AI chip and Windows 11. However, experts have successfully run Recall on other computers, particularly those with ARM processors, and even on x86 architecture machines and Azure virtual machines. 

This indicates that Recall doesn't require unique hardware, suggesting it may soon be offered to all sufficiently powerful Windows computers. Given Microsoft's tendency to automatically activate new features, users might find Recall enabled without explicit consent.

Recall is not available on Windows 10 or earlier versions. On Windows 11, users can check for Recall by typing "Recall" in the Start menu search bar. If the application appears in the search results, it indicates that Recall is installed and requires configuration or disabling.

Final thoughts

While Microsoft's Recall promises to enhance user experience by providing a comprehensive search and recall capability, it also poses significant privacy and security risks. 

Users must remain vigilant, properly configure the feature, and implement strong cybersecurity practices to mitigate potential threats. Balancing the convenience of Recall with the need to protect sensitive information will be crucial as this feature rolls out more broadly.

Telegram, known for its openness and anonymity, has long been a leading platform for information dissemination. However, this freedom brings challenges: fake news, scam projects, and manipulation thrive in the unregulated flow of messages.

To tackle this issue, Telegram has announced the introduction of a fact-checking feature. Today, we'll examine whether this can be a real shield against misinformation or just a decorative addition.

The stream of news and fact-checking

Millions of users worldwide use Telegram for messaging, news updates, and participating in groups and channels. However, amidst this information flow, false news, political propaganda, and fake videos often slip through.

In recent months, there have been increasing instances where official Telegram channels have spread unchecked information, which later turned out to be false. Public channels chase speed, aiming to be the first to publish "hot" news, often at the expense of fact-checking. 

False information can cause real harm by manipulating public opinion, undermining trust in sources, and even pushing people toward dangerous actions. Thus, combating misinformation has become a pressing necessity.

Fact-checking involves verifying the accuracy of information, identifying factual errors, distortions, and manipulations. It includes analyzing information, comparing it with authoritative sources, and checking facts.

Fact-checking in social media and messengers

The idea of verifying information before publication is not new. Telegram is not the first to implement such a feature in a messenger or social network.

Similar mechanisms already exist in other messengers and social networks. Here are some examples:

Meta
Introduces labels "Verified by independent fact-checkers" for posts containing verified information and blocks the distribution of materials recognized as fake.

X
Uses a fact-checking system where users can report suspicious posts, which are then verified by experts.

Google
Includes "Fact-checking" labels in search results, allowing users to see verified data immediately.

TikTok
Develops algorithmic systems for content ranking and identifying potentially dangerous materials, including deep fakes.

The effectiveness of these tools in combating fake information is ambiguous. On one hand, they raise awareness, helping users critically assess information and spot fakes. On the other hand, their efficiency is limited due to the vast volume of information online.

Telegram’s plans 

A few weeks ago, a fact-checking option was spotted in Telegram's source code. The concept is as follows:

• Telegram grants local authorities permission to join the fact-checking system.
• Representatives of local authorities (agencies or authorized individuals) verify posts.
• After verification, they add a "Fact-check" label, where additional context or information can be included.

According to Telegram's founder, the news in a channel or chat will remain unchanged for all users. However, the fact-check label with additional context will be visible only to citizens of a specific country. This affiliation will be determined by the phone number linked to the Telegram account.

Information security in fact-checking 

While the fact-checking feature can be useful, it does not guarantee full protection against deepfakes. It will notify users about the risks of spreading deep fakes, for instance, by warning about the inaccuracy of videos or images. However, there are downsides — deep fakes are often difficult to distinguish from real videos or images, and fact-checking cannot always be certain of its results. From an information security and hygiene perspective, this feature is not very beneficial for users.

The focus here is more on processing and analyzing textual information. To protect against scammers and recognize deep fakes, a different approach is needed, as these involve media data: voice, video, or photos.

The most effective features from an information security standpoint are SCAM labels and anti-fraud measures that detect suspicious account activity. This is useful when, based on the IP address from which the user is logged in and their behavior, the account is temporarily blocked. Another useful feature is identifying suspicious links that may be potentially dangerous, such as phishing links.

Collaborating with independent fact-checking organizations

Collaborating with independent fact-checking organizations is a key strategy in combating misinformation. These organizations provide unbiased and thorough analyses of questionable claims circulating online. 

By integrating their databases and verification methods, Telegram can offer users a reliable way to cross-check information within the platform. Research has shown that users are more likely to trust and engage with content that has been independently verified. For instance, Facebook’s collaboration with third-party fact-checkers has significantly reduced the spread of false news stories. Implementing similar partnerships can enhance the credibility of information on Telegram, helping users to make more informed decisions.

More than just fact-checking

A key point in protecting against misinformation is improving users' media literacy. It's important to teach people to independently analyze information and distinguish truth from fiction. This requires developing critical thinking: learning to ask questions, analyze sources, and check facts. Additionally, developing media consumption skills is necessary: distinguishing news from entertainment materials, identifying advertisements and propaganda. And, of course, educating about digital technologies: understanding social media algorithms and mechanisms for spreading information.

Another important element is the development of independent fact-checking organizations. They play a crucial role in combating misinformation by conducting in-depth analysis of information, using a wide range of sources, experts, and verification methods. They publish the results of their work, providing an evidence base, helping to debunk myths and false claims. Furthermore, they also educate users, promote critical thinking, and contribute to media literacy development.

Smart medical devices represent one of the most significant advancements in healthcare technology, offering the potential to significantly improve patient care, enhance the efficiency of healthcare delivery, and enable new forms of treatment that were previously unimaginable. However, as with any technology, particularly those that are interconnected and data-dependent, they also bring a set of risks, especially concerning security and privacy. This dual nature raises a crucial question: Are smart medical devices indispensable, or are they a security risk? This discussion delves deep into this topic, exploring the benefits, risks, and the complex interplay between indispensability and vulnerability in the context of smart medical devices.

The indispensability of smart medical devices

Smart medical devices have revolutionized healthcare in myriad ways, fundamentally transforming the landscape of medical treatment and patient care. These devices, ranging from wearable fitness trackers to advanced implantable technology, have ushered in a new era of healthcare where real-time monitoring and personalized medicine are not just ideals but realities.

For patients with chronic conditions like diabetes or heart disease, smart medical devices have been nothing short of transformative. Smart insulin pumps, for example, can continuously monitor blood glucose levels and adjust insulin doses accordingly, offering a level of fine-tuned management that was previously unattainable. Cardiac monitors and other wearable devices can detect irregularities in heart rhythms and alert patients and doctors to potential issues before they become critical. This continuous monitoring not only provides a comprehensive picture of the patient's condition but also empowers them to manage their health proactively.

The advent of telehealth and remote patient monitoring, especially accelerated by the COVID-19 pandemic, has underscored the indispensability of these devices. Patients no longer need to make frequent hospital visits, which can be both time-consuming and costly. Instead, they can receive high-quality care from the comfort of their homes, reducing their exposure to potential infections and other health risks. This shift not only makes healthcare more accessible but also more patient-centric, with treatments tailored to fit the individual's lifestyle and needs.

Furthermore, smart medical devices are at the forefront of personalized medicine. By gathering and analyzing data over time, healthcare providers can gain a deep understanding of a patient's unique health profile, enabling them to tailor treatments more effectively. This data-driven approach can lead to better health outcomes, fewer adverse drug reactions, and a more efficient healthcare system overall.

The security risks

The quantity of interconnected medical devices is surging, with predictions suggesting that the international medical IoT market could exceed US$600 billion by 2028. This proliferation of connected medical technology broadens the potential targets for cybercriminals, offering them increased opportunities to breach networks. Particularly concerning are ransomware attacks, which can paralyze networks, hinder access to vital patient information, and disrupt the functionality of connected devices.

The healthcare sector's reliance on essential medical technologies like MRI machines and insulin pumps makes it especially susceptible to these cyber threats, as any disruption can directly impact patient care and potentially endanger lives. Even systems that support these technologies, like appointment scheduling software, are at risk and can cause significant operational disturbances.

Cybercriminals are acutely aware that healthcare providers are often in a desperate position to regain system functionality, making them prime targets for extortionate ransom demands. This places healthcare providers in the precarious situation of having to decide between potentially financing future cybercriminal activities or endangering patient welfare.

Moreover, adversaries frequently aim to pilfer patient data, a valuable asset on the dark web, which can be used for blackmail, extortion, or to orchestrate further targeted cyberattacks. A notable example is the Barts Health NHS Trust in the UK, which fell victim to the notorious BlackCat group, resulting in the theft of over 70 terabytes of sensitive data.

Why does the healthcare sector find it challenging to secure IoT devices?

The inherent nature of connected devices introduces security complexities across all industries. Introducing smart technology typically means integrating numerous new devices into the network, each with its own set of proprietary software and management requirements. Many of these devices, especially older models, weren't initially designed with robust security measures, and activities such as applying security patches can be cumbersome.

Healthcare providers encounter more obstacles than most due to the inclusion of high-cost equipment like CAT scanners and MRI machines in their IoT arsenal. These expensive assets are not easily replaceable as they age, and the constant use they undergo makes routine security maintenance challenging.

Consequently, managing a network of connected medical technology demands substantial resources from IT and security teams who already face extensive responsibilities.

How can healthcare organizations enhance IoT security with finite resources?

Healthcare institutions are experiencing significant budget constraints, particularly NHS Trusts. Therefore, healthcare executives face the challenge of enhancing IoT security without incurring prohibitive costs.

Cybersecurity competes for funding within a tight budget, but considering the average cost of a healthcare data breach was US$11 million in 2022, it's an area that can't be overlooked. This places a premium on achieving a high return on investment in cybersecurity, focusing on strategies that maximize coverage and effectiveness while minimizing expenses.

One strategy is to secure the broader IT network rather than trying to fortify each connected device individually. An emerging network security paradigm, known as Unified Secure Access Service Edge (SASE), offers a solution by consolidating various security services into a single platform. This approach simplifies the process of securing an increasingly complex array of connected medical devices without substantially increasing costs.

Final thoughts 

While smart medical devices are indeed indispensable for modern healthcare, they are not without their security risks. The key is not to shun these devices out of fear but to understand and mitigate the risks they pose. By working together, manufacturers, healthcare providers, regulators, and patients can harness the incredible potential of smart medical devices while ensuring they are safe and secure for all who rely on them. The future of healthcare is smart, but it must also be secure.

When employees find the standard security measures of their organization cumbersome and annoying, it can significantly increase the risk of internal threats. For example, a recent report by Gartner stated that 69% of employees regularly ignored cybersecurity recommendations within their organization. This does not mean that such individuals deliberately create security risks to spite management. More often, it means they simply want to do their job without unnecessary distractions, considering cybersecurity measures as needless and time-consuming hassles.

Can cybersecurity inherently be combined with a pleasant user experience? 

Passwords are a prime example of the clash between cybersecurity and user experience. The average office worker might have up to 190 different login and password combinations. Naturally, remembering such an overwhelming number and matching them in one's mind to the required services is practically impossible.

61% of employees admit to reusing passwords as a way to cope with this situation. At the same time, most of them are acutely aware that such an approach can have dire consequences for the company's security. So, how can IT departments improve password security in their organizations, knowing that users are already burdened by these endless digital defense measures and have long prioritized convenience and speed, consciously sacrificing security.

Although many tech giants are currently actively promoting passwordless access technologies, eliminating passwords is unfortunately not yet a viable option for most organizations. That is why it is extremely important to choose the most effective security methods that can simultaneously provide a pleasant user experience. Below, we will explore four of the best ways to engage end-users in more responsible password use, in a way that they might even enjoy.

Key phrases for creating strong and memorable passwords

Hackers often use brute force methods to quickly try many different options in a row in an attempt to crack a specific account's password. They frequently combine these methods with dictionaries of known vulnerable passwords, including sequential passwords like "qwerty" or "123456," which users often apply. Shorter and less complex passwords are much more vulnerable to this method of attack, so the standard advice is to create longer passwords of certain complexity.

Of course, such requirements are a headache for users, who now need to remember a multitude of long and complex passwords, ideally consisting of 15 characters and above. One way to simplify this task is to suggest using key phrases instead of traditional passwords.

A key phrase is three or more random words strung together, for example, "Pig-Lion-Window-Night." At first glance, such a password may seem fairly simple and insecure, but even it contains 19 characters, special characters, and capital letters. These factors are enough to make brute force attempts take a vast amount of time. If a few more special characters or numbers are added, one can confidently assert that hackers stand no chance of success. The main thing is to use words that are not related to the company's activities or the personal data of a specific user.

Overall, key phrases are an excellent way for endpoint users to create longer and more complex passwords without increasing their cognitive load.

Recommendations and feedback

Asking an employee to create a new password often makes them feel as if all basic knowledge has left their mind, leading to a lengthy thought process that can take hours. "What password should I create that is both convenient and secure?" the user might think.

It is very important to be in touch with colleagues during such a difficult moment: to give clear recommendations and answer questions. No one should feel as if they are left to their own devices when taking steps directly affecting the security of the entire organization. Ideally, of course, an exhaustive memo with all recommendations and examples should be created so that the password creation process is quick and painless. But even such memos often do not cover all the needs and questions of users.

Providing dynamic feedback during the creation of a password is not only a learning opportunity for the user but also an instant check to see if the password meets the security policy requirements. By consulting with an IT specialist, employees can understand in real time whether their new password complies with the company's policy, and if not, why, and quickly correct it.

Password expiry based on its length

No one likes it when work is stalled due to the need to change a work password again. Sometimes this moment comes too quickly and even greatly irritates the most conscientious employees who take security very seriously. However, using passwords with an indefinite validity period is simply unacceptable in today's realities, as such passwords open many doors for cunning hackers. That's why the regular changing of passwords is so widely used by many organizations.

But why not turn a potentially negative user experience associated with the forced change of a password into a promising opportunity?

Password expiry depending on its length provides end-users with a choice. They can create a relatively simple and easy password that only partially meets the organization's requirements, but they will need to replace it again, for example, in 90 days. Or they can extend the length of the password and not touch this issue for as long as possible, for example, the next 180 days.

Instead of all employees facing a forced password reset every 90 days, a flexible validity period based on its length rewards users who choose longer and safer passwords. This solution provides the best balance between security and ease of use.

Continuous monitoring of compromised passwords

The previously discussed methods are quite effective in helping end-users create more reliable passwords and provide them with greater transparency and understanding of their organization's security policies. However, even reliable passwords can be compromised. And it's impossible to be 100% sure that company employees aren't using the same passwords to authorize themselves in several services at once. That's why it's necessary to have a way to promptly detect compromised passwords and quickly block potential routes for attacks.

Many cybersecurity solutions have the ability to periodically check user passwords against leaked lists of compromised credentials, but these solutions are not perfect, as monitoring is not conducted in real-time. The optimal solution would be to choose a security solution that continuously scans passwords for leaks and immediately notifies the administrator, or even automatically resets such a password, to not give hackers a second for potential compromise. The market for information security solutions is currently very diverse, so finding a product with such functionality should not be difficult.

Conclusion

Passwords do not necessarily have to provoke indignation and irritation. As we have seen above, by choosing the right approach to interaction between the IT department and users, this problem simply disappears on its own.

Using Passwork, the issues aforementioned evaporate. This tool helps organize the storage and access to passwords, making the process more manageable and secure. Key password phrases, feedback during password reset, length-dependent expiry, and continuous scanning for compromised passwords are excellent solutions that can significantly enhance the security of any organization.

The popularity of push notifications can be easily explained – marketers have noticed that customers are more likely to read short messages that don't need to be opened and are more likely to click on links contained within them. Therefore, various companies have long adopted and actively used this communication channel with customers. However, malicious actors use push notifications for phishing, spreading malware, and other cyber threats. This article discusses the schemes used by malicious actors, what service developers need to consider, and how not to become a victim of fraudsters.

How malicious actors use push notifications

A push notification resembles an SMS, consisting of a title and a short message, an icon with the sender's name, and it may also include an image and buttons to perform a certain action, such as clicking a link. Additionally, the differences between push notifications and SMS include that the latter are received on any model of mobile phone and are delivered through mobile operators. Receiving push notifications requires a smartphone that supports this feature, the installation of applications, and internet access. Users can manage notifications themselves: prohibit, fully allow, or partially allow. Push notifications are usually stored in the personal account on the website, in the application, or in the notification center if the phone is on iOS and in the notification log if you have Android 10 and above.

The most common methods include sending push notifications that masquerade as official notifications from banks, online stores, or other services to prompt users to enter personal data or bank card details on phishing sites. One of the freshest instances involved a victim showing their screen to fraudsters, who posed as a bank security service and saw all push notifications with confirmation codes, allowing them to rob the victim.

From the users' perspective, push notifications seem convenient. A person receives dozens of pushes a day – from media, banks, marketplaces, and messengers. The short texts inform about discounts, new stock arrivals, promotions, and reminders. Moreover, push notifications deliver alerts about funds being debited or credited, codes for authentication, and access to one's account or personal cabinet on various services and sites. Malicious actors exploit this – due to the large amount of incoming information and often, lack of attention, a victim of fraud can easily click on a link in a pop-up "push."

Among relatively new attack methods is the ‘Fatigue’ attack, another form of social engineering. The essence of this method is to send the user a large number of login confirmation requests, thereby catching him off guard and scattering his attention. Eventually, the person is likely to accept the request to eliminate the "spam" on their phone or decide that the system is broken and that they need to "press the button" to fix everything.

The attack targets users whose first factor, most often a password, has already been compromised, although this is not such a big problem, considering the size of leaked password databases. By overcoming the two-factor authentication system in this way, malicious actors penetrated some corporate systems of Uber, Microsoft, and Cisco, and in 2024, Apple users faced this issue. Since successful attacks on large corporations continue, it can be concluded that businesses are not yet ready to repel such attacks.

In late February 2024, The Washington Post published an article about a new method the FBI uses to surveil suspects using push notifications. The agency filed more than 130 orders to disclose data of push notifications in 14 states. This became possible thanks to a feature of "pushes." When a user registers in an app, Apple and Google servers create and store a unique identifier - the "push token." This token can later be used to identify a person using the app based on device information.

Data protection advocates are concerned that this capability poses a threat to users' privacy from both the state and malicious actors. To send a victim push notifications, a fraudster must infect the device with malware. For example, the banking trojan Ginp was discovered by Kaspersky Lab. In addition to the standard set of abilities for a banking trojan: transmitting the entire contact list to its owners, intercepting SMS, and overlaying the screen with fake pages, the malware uses fake push notifications to convince the victim to open a phishing page.

Recommendations for service developers

Before connecting push notifications to a service, it's recommended to study their weaknesses and plan for data protection from leaks. Limit the information transmitted to the push notification service, including metadata.

There are several security measures. Firstly, do not use Push notifications to access valuable digital resources. Instead, use other protection tools for login, such as TOTP or physical tokens with a built-in password generator or digital certificate.

Secondly, implement throttling mechanisms in server systems for sending Push notifications. A well-designed push factor should offer the user options to reduce automatic responses. For example, it displays several options with numbers, and the user must choose what they see on the device they are logging in from.

Thirdly, report attack attempts to SOC and make quick decisions on temporarily blocking compromised accounts. Also, the importance of encryption when working with push notifications cannot be overlooked. And remind users of cybersecurity rules to prevent illegitimate actions by malicious actors.

For user protection, developers should follow several principles:

Сontent validation
Before sending a notification, ensure it doesn't contain potentially dangerous links or requests;

Use of secure protocols
All communication between the app and server, as well as the push notification server, should use encryption (e.g., via HTTPS);

Regular updates and dependency control
Used libraries and dependencies should be regularly updated to avoid known vulnerabilities;

User education
Provide information about notification settings and the dangers of fraudulent messages.

Protection measures

To avoid becoming a victim of fraudsters, users need to follow several rules, including being vigilant not automatically accepting offers, and not thoughtlessly clicking on links from ‘Pushes’. For security when using push notifications, users should only download official bank apps from their official websites and avoid installing apps from unverified sources.

Be cautious with push notifications about transactions and password change requests – verify such information through official communication channels with the bank.

Push notifications can appear on device lock screens, allowing unauthorized access to information in push notifications if the device falls into the wrong hands. Add a screen lock and configure the allowable information to be displayed on the screen for push notifications.

It's better to simply disable unnecessary notifications, and delete unnecessary apps from the phone. When "pushes" can be sent by a limited number of services, it's easier to notice a suspicious message.

Wrapping up 

In summarizing our exploration into the realm of push notifications, it's evident that these alerts occupy a significant role in our digital ecosystem. They serve as efficient conduits for information, offering immediate updates on transactions, sales, and various notifications directly relevant to our daily activities. However, this convenience also presents an avenue for malicious entities to exploit, using these notifications as a means to deploy phishing attacks, distribute malware, or engage in identity theft.

Despite these vulnerabilities, there is a concerted effort from the development community to enhance the security and integrity of push notification systems. Through the adoption of encryption and the implementation of more rigorous security protocols, developers are creating a more resilient framework to protect users from potential threats. Additionally, there is an emphasis on user education, encouraging individuals to exercise discretion and vigilance when interacting with push notifications.

For users, adopting a proactive approach to digital hygiene can significantly mitigate the risks associated with push notifications. This includes verifying the authenticity of apps before downloading, being cautious about the personal information shared within apps, and utilizing the security features provided by their devices. Periodically reviewing and customizing notification settings can also prevent unauthorized access to sensitive information, further safeguarding against fraudulent activities.

Ultimately, push notifications represent a dual-faceted feature of modern technology – providing essential information swiftly while posing potential security risks. By fostering a culture of awareness and implementing robust security measures, both developers and users can navigate these challenges effectively. As we continue to integrate these notifications into our daily lives, maintaining a balance between convenience and security will be paramount. In doing so, users can leverage the benefits of push notifications without compromising their digital safety.

The name "Bluetooth" is derived from the name of Harald Bluetooth, a king who was known for uniting Danish tribes in the 10th century. Similarly, bluetooth technology, developed in the late 1990s, was created as a wireless alternative to RS-232 data cables, unifying various communication protocols into a single universal standard. 

However, mass unification comes with its risks. Indeed, the recent discovery of a significant Bluetooth vulnerability across several operating systems, including Android, macOS, iOS, iPadOS, and Linux, has raised alarms in the tech community. 

This vulnerability, discovered by security expert Mark Newlin, opens the door to potential contactless hacking of devices without any action required from the device owner. It poses a serious threat, especially considering the widespread use of Bluetooth technology in modern devices. Today, we’ll be discussing some of Bluetooth’s vulnerabilities with the help of Newlin’s report. 

Counterfeit keyboards

The crux of the problem lies in the ability to compel a vulnerable device to establish a connection with a counterfeit Bluetooth keyboard, all without requiring user confirmation. This is achieved by circumventing the Bluetooth protocol's authentication checks, which, in specific implementations of Bluetooth stacks in popular operating systems, allow an attacker to exploit this inherent mechanism. Subsequently, this connection can be exploited to issue commands, granting the attacker the capability to perform actions on the compromised device on behalf of the user, without any additional authentication, such as a password or biometrics (e.g., fingerprint or facial recognition). Newlin, the security researcher who unearthed this vulnerability, emphasized that a successful attack does not necessitate a specialized setup; even a standard Bluetooth adapter on a Linux-based laptop can be used for exploitation.

It's worth noting that the attack's practicality is limited by the proximity requirement between the attacker and the victim, as Bluetooth connections typically have a short range. While this restricts mass exploitation, it does pose a potential threat to individuals who may be targeted by attackers for specific reasons.

Android 

Android devices have been subjected to rigorous scrutiny with regard to the aforementioned vulnerability. Newlin conducted tests on seven different smartphones running various Android versions, ranging from Android 4.2.2 to Android 14. Remarkably, all of them exhibited vulnerability to Bluetooth hacking. In the case of Android, the only prerequisite for a successful hack is that Bluetooth is enabled on the target device.

The researcher promptly alerted Google to this discovered vulnerability in early August. Consequently, Google has already developed patches for Android versions 11 to 14 and shared them with smartphone and tablet manufacturers that rely on this operating system. These manufacturers are expected to release corresponding security updates for their customers' devices in due course. It is imperative for users to install these patches as soon as they become available for their Android 11/12/13/14-based devices. For older Android versions, no updates will be forthcoming, leaving them perpetually susceptible to this attack. Thus, turning off Bluetooth remains a prudent precaution until the end of these devices' life cycles.

MacOS, iPadOS, and iOS

In the case of Apple's operating systems, the researcher had a more limited range of test devices at his disposal. Nonetheless, he was able to confirm the presence of the vulnerability in iOS 16.6, as well as in two versions of macOS: Monterey 12.6.7 (x86) and Ventura 13.3.3 (ARM). It is reasonable to assume that a broader spectrum of macOS and iOS versions, including their counterparts, iPadOS, tvOS, and watchOS, could potentially be susceptible to a Bluetooth-based attack.

Regrettably, Apple's enhanced security feature, known as Lockdown Mode, introduced in the past year, does not provide protection against this particular Bluetooth vulnerability. This applies to both iOS and macOS.

Fortunately, a successful attack on Apple's operating systems necessitates an additional condition, in addition to Bluetooth being enabled: the device must have the Apple Magic Keyboard paired with it. As a result, the risk of an iPhone being compromised through this vulnerability appears to be minimal.

Linux

This attack is also applicable to BlueZ, a Bluetooth stack that is included in the official Linux kernel. Newlin verified the Bluetooth vulnerability in various versions of Ubuntu Linux, including 18.04, 20.04, 22.04, and 23.10. The bug that enabled this attack was identified and patched in 2020 (CVE-2020-0556). However, the fix has been deactivated by default in most popular Linux distributions, with only ChromeOS having it enabled (based on information obtained from Google).

The Linux vulnerability discovered by the researcher is designated as CVE-2023-45866 and is rated at 7.1 out of a possible 10 (CVSS v3) with a "moderate" threat status, according to Red Hat. A successful exploit of this vulnerability requires just one condition to be met: Bluetooth discovery or connectivity must be enabled on the Linux device. The good news is that a Linux patch addressing this vulnerability is already available, so it is strongly recommended to install it as soon as possible if it has not been done already.

Final thoughts 

In conclusion, the discovery of a critical Bluetooth vulnerability affecting popular operating systems such as Android, macOS, iOS, iPadOS, and Linux highlights the ongoing risks associated with modern technology. However, it's essential to note that many of these companies have responded promptly to the issue, releasing patches and updates to address the vulnerability. This demonstrates their commitment to enhancing security for their users.

While this story underscores the constant vigilance required in the ever-evolving landscape of cybersecurity, it also serves as a reminder that hackers are not dormant, they continuously seek new vulnerabilities to exploit. As technology advances, the responsibility to remain proactive in protecting our devices and personal information becomes increasingly crucial.

In the digital era, where the internet and electronic devices dominate every aspect of our lives, the importance of data security cannot be overstated. Zip archives, a common format for compressing and storing data, are no exception to the need for stringent security measures. Typically, passwords are employed to protect the contents of these archives. 

However, challenges arise when one forgets the password to a zip file or seeks to evaluate the robustness of their data encryption. 

This article delves into the motivations behind zip archive password cracking and the prevailing methods. Additionally, it offers valuable advice on safeguarding your data against unauthorized access.

Understanding the motivations for cracking zip archive passwords

The act of cracking zip archive passwords can stem from both legitimate and malicious intentions. On the legitimate side, the most common scenario involves individuals attempting to regain access to their own archives after forgetting the password. This forgetfulness is a natural human trait, especially when dealing with numerous passwords for different files and services. On the other hand, the conversation around archive cracking often highlights two main concerns. The first is the ability to crack a password-protected archive to retrieve its contents. The second, more alarming issue, involves exploiting vulnerabilities in the archiving software to gain unauthorized access to a user's computer system.

Fortunately, the current landscape of archive cracking offers a silver lining. Attackers are primarily limited to brute-force attacks, where they attempt to guess the password by trying numerous combinations. This method's effectiveness heavily relies on the complexity of the password. A sufficiently complex password can significantly enhance the security of your data. However, the situation becomes more complicated when considering the vulnerabilities within the archiving software itself. These vulnerabilities can be discovered periodically, making it imperative for users to keep their software updated to prevent potential exploitation by hackers.

Cybercriminals have various motivations for wanting to crack zip archives. These include gaining unauthorized access to confidential information, circumventing copyright protection, bypassing security restrictions and policies, and modifying or destroying data. Such actions can lead to significant breaches of privacy and financial loss. To mitigate these risks, it is advisable to use reputable archiving software and ensure that all necessary updates and patches are applied promptly.

Methods for cracking zip archives

Gaining access to a zip archive without the password involves eliminating and guessing. The unlimited password attempts feature of zip archives makes them vulnerable to brute-force attacks. Various tools and techniques are available for this purpose, each with its own set of strategies:

Full brute-force attack
This method is applicable when no information about the password is known. It involves trying every possible combination within a specified range, allowing for customization based on known password characteristics.

Brute-force attack with extended mask
When some information about the password's structure is known, this method allows for a more targeted approach, reducing the number of guesses needed.

Dictionary attacks
These are effective when the password is suspected to be a common word or phrase. Unfortunately, the tendency of users to choose simple, easily guessable passwords makes many archives vulnerable to this type of attack.

Tools such as John the Ripper, Advanced Archive Password Recovery, KRyLack ZIP Password Recovery, and ZIP Password Cracker Pro are among the most popular for cracking archive passwords.

Enhancing the security of zip archives

The relative ease with which zip archives can be cracked necessitates the adoption of additional protective measures. A robust password is the first line of defense, ideally incorporating a mix of characters, numbers, and symbols to increase complexity. Such passwords are significantly more challenging to crack, providing a strong barrier against unauthorized access.

Beyond passwords, the level of protection should be tailored to the value of the data being secured and the user's knowledge of information security. Encrypting files before sharing them over the internet adds an extra layer of security. For instance, using a zip archive with a strong password for encryption, and then sharing the password through a separate communication channel, can prevent unauthorized access even if the primary transmission method is compromised.

In addition to the fundamental security measures previously discussed, adopting advanced security practices can significantly enhance the protection of zip archives.

Implementing Multi-Factor Authentication (MFA) can dramatically increase the security of your zip archives. While not a standard feature for archive access, integrating MFA through secure storage solutions or encrypted file systems adds a critical security layer. MFA requires users to provide two or more verification factors to gain access, combining something they know (like a password) with something they have (such as a security token or a mobile phone confirmation). This method ensures that even if a password is compromised, unauthorized access to the archive remains highly unlikely.

While zip archives support password-based encryption, users seeking higher security levels should consider additional encryption layers. Tools like VeraCrypt or BitLocker offer robust encryption for files and folders, including zip archives. By encrypting the entire storage container that holds the zip archive, users can protect against both unauthorized access and more sophisticated attacks that target file-level encryption vulnerabilities.

Conducting regular security audits and vulnerability assessments of the systems storing zip archives can identify potential security weaknesses before they are exploited. This proactive approach involves scanning for vulnerabilities, assessing the risk level of identified vulnerabilities, and implementing necessary patches or security enhancements. Regular audits ensure that both the software used for archiving and the broader system environment remain secure against emerging threats.

Finally, educating users on security best practices plays a crucial role in safeguarding zip archives. This includes training on creating strong passwords, recognizing phishing attempts, and safely sharing sensitive information. A well-informed user is the first line of defense against many common cyber threats, making education a vital component of any comprehensive security strategy.

Final thoughts 

In conclusion, while zip archives offer a convenient means of compressing and storing data, their security is not infallible. Users must employ strong passwords, take advantage of encryption options, and keep their software up to date to protect their data effectively. Additionally, it's crucial to remember that unauthorized cracking of archives not only violates legal statutes but also infringes on the privacy and confidentiality of individuals. By adopting a proactive approach to data security, users can safeguard their information against the evolving threats in the digital landscape.

The counterfeiting of well-known apps remains a popular tool for spreading malicious software. For instance, in 2022, a counterfeit version of the popular messaging app WhatsApp tricked thousands of users into downloading it from unofficial sources, leading to the harvesting of personal data and intrusive ads. 

Cybercriminals employ various tactics to deceive users into downloading fake apps through email, dangerous websites, and social media. This article will provide recommendations to help you identify a fake app before downloading and completely remove it from your smartphone. Let's take a look today at the dangers they pose, their prevalence, and the steps you can take to protect yourself against these threats.

The dangers they pose

Installing malicious software on your phone can expose you to numerous threats, ranging from slowing down your device to spying on you. One of the most common risks is the theft of confidential and personal data. Malicious apps can steal your private information, such as contacts, photos, and messages, which can then be sold to other fraudsters or used for identity theft. Another significant threat is financial theft, where cybercriminals can access your financial information, such as banking apps and cryptocurrency wallets, to steal your money.

Malicious apps can also cause performance issues on your device, leading to slower operation, overheating, or rapid battery drain due to background processes. Additionally, these fake apps may display a large number of ads, known as adware, which can be intrusive and significantly reduce the usability of your device.

Spying is another critical threat posed by malicious apps. These apps can eavesdrop on your conversations, read your messages, and monitor your activities, severely compromising your privacy. If you use your smartphone for work, malicious apps can engage in corporate espionage by stealing corporate data, which can lead to potential business losses and security breaches.

The prevalence of fake apps

In recent years, these threats have become increasingly common. Some target a wide range of users, while others are more specific. Notable examples of malicious fake apps include counterfeit versions of WhatsApp and Telegram, spread through dozens of fake websites. Once installed, these fake apps intercepted victims' chat messages to steal their confidential information and cryptocurrency.

Another example is the spread of BadBazaar spyware disguised as Signal and Telegram by hackers linked to China. Both types of fake apps passed official verification and were available on Google Play and the Samsung Galaxy Store.

How to prevent fake apps from reaching your device

To reduce the likelihood of installing threats on your device, it is crucial to take several preventive measures. Always install the latest versions of your operating system and software, as threats often exploit vulnerabilities in older versions. Before downloading any app, verify the developer's reputation online and check for any reviews of the app to ensure its legitimacy. It's also essential to use official app stores, as they have strict vetting processes to prevent threats from reaching the platform.

Removing any apps you don't use can help you monitor what is on your device more effectively. Be cautious about clicking on links or attachments, especially if they appear in unsolicited social media messages or emails and offer to download something from third-party sites. Similarly, avoid clicking on ads on the internet, as they may be part of a scam aimed at redirecting you to a counterfeit app.

When installing new apps, be cautious when granting permissions that are unrelated to the app's functions, as this could be a sign of malicious software trying to access your data. Using biometric data for login instead of simple passwords in your accounts can also enhance your security.

Lastly, employing security solutions that provide enhanced protection with effective threat detection, blocking malicious websites, safeguarding online payments, and managing passwords. By following these steps, you can significantly reduce the risk of installing fake apps on your device and protect your personal and financial information from cyber threats.

It's also important to monitor unusual activity on your device if malicious software does manage to infiltrate it. For example, be alert if your battery drains faster than usual. Also, if your device runs slower, it may be due to malicious software. Pay attention to persistent pop-up ads, as this could indicate that you have installed adware. Watch for any unusual icons appearing on your screen.

10 additional tips and tricks 

1. Educate Yourself on Common Threats
Understanding the various types of malware and how they typically operate can help you stay vigilant. Common types include trojans, spyware, adware, and ransomware. Each has distinct characteristics and signs that can alert you to their presence.

2. Regularly Update and Patch Software
Make sure all your apps, not just the operating system, are regularly updated. Developers often release patches for known vulnerabilities, so keeping your software current is crucial in preventing exploitation by malicious actors.

3. Monitor App Permissions
Review the permissions of apps already installed on your device. Apps should only have access to the information and functions necessary for their operation. For instance, a flashlight app should not need access to your contacts or messages.

4. Utilize Multi-Factor Authentication (MFA)
Wherever possible, enable MFA for your accounts. This adds an extra layer of security, making it harder for unauthorized users to gain access even if they obtain your password.

5. Backup Your Data Regularly
Ensure you have regular backups of your important data. This practice can save you from losing vital information if your device is compromised. Use cloud services or external storage devices for these backups.

6. Be Skeptical of Free Offers
If an app promises something that seems too good to be true, it probably is. Be cautious of free versions of popular apps that offer the same functionality without any apparent revenue model. These could be traps to lure you into installing malware.

7. Use Strong, Unique Passwords
For each of your accounts, use a unique password that combines letters, numbers, and symbols. Avoid using easily guessable information like birthdays or simple sequences. Password managers can help you keep track of your passwords securely.

8. Regularly Scan Your Device for Malware
Use reputable antivirus and anti-malware software to scan your device regularly. These tools can detect and remove many types of malware before they cause significant harm.

9. Stay Informed on the Latest Threats
Cybersecurity is an ever-evolving field. Stay informed about the latest threats and trends by following trusted sources. This knowledge can help you recognize and avoid new types of attacks.

10. Use Secure Networks
Avoid using public Wi-Fi for sensitive transactions, such as online banking. Public networks can be less secure, making it easier for attackers to intercept your data. Use a virtual private network (VPN) to add a layer of security when connecting to public Wi-Fi.

Conclusion

Today, smartphones and tablets are our gateways to the digital world. But this world must be protected from unwanted guests. By following these simple steps and additional measures, your finances and personal data will be better protected. Stay vigilant, stay informed, and take proactive steps to secure your digital life.

By incorporating these practices into your daily routine, you can create a robust defense against the ever-present threat of fake apps and other forms of cybercrime. Your digital safety is paramount, and with the right knowledge and tools, you can navigate the digital world securely and confidently.

The world has grown accustomed to social media, where users upload millions of images and videos daily. However, not everyone realizes that an innocent-looking selfie at work could be used by malicious actors to break into a company or that a hotel photo might lead to blackmail.

With the advancement of technology and the expansion of geospatial information systems, cybersecurity threats have also increased, demanding more careful consideration of the data being published. This article explores what GEOINT is, how criminals use your photographs for their purposes, and why people scrutinize Google Maps.

What is GEOINT?

GEOINT, short for "Geospatial Intelligence," involves the analysis and use of imagery and geospatial information to gain insights into activities on Earth. It combines several disciplines: cartography, charting, image analysis, and imagery intelligence. While traditionally associated with the military, geospatial intelligence is increasingly utilized by civilian sectors, including telecommunications, transportation, public health, safety, and real estate, to enhance daily life quality. In broader applications, geospatial intelligence is used for emergency planning, crime and security monitoring, and protecting critical infrastructure.

Technological advancements have brought a new era in geospatial intelligence. The advent of powerful analytical software, ubiquitous geolocation data, far-reaching broadband connections, rapidly developing computational power, affordable cloud storage, advanced analytics, and artificial intelligence have all played a role in the revolution of geospatial intelligence.

GeoGuessing

In the context of geospatial intelligence, the phenomenon of geo guessing is worth mentioning. The term comes from the name of the browser game GeoGuessr, launched in 2013. The game uses Google Street View maps, requiring players to guess the location of a street/alley/highway worldwide by marking it on Google Maps. Since 2015, the game has also been available as an iOS app.

The game has become so popular that competitions and tournaments are held. In 2023, the GeoGuessr World Championship finals were held in Stockholm with a prize pool of $50,000. Clues include road markings, languages on signs and plaques, animals and people in the frame, and other details. The most professional players can recognize a location on the map by a 3D image within seconds, requiring extensive time studying maps.

How criminals use GEOINT

An example of careless handling of personal information is found in an interview with Michael Oren, a former Israeli ambassador to the U.S. Attentive viewers noticed a note with login credentials in the background during the shoot from his home. Imagine the damage a criminal could cause in such a situation. 

Be vigilant and cautious when sharing your photos on social media. Like any other information obtained through theft or leakage, data from open sources can be used by malicious actors. Here are some ways they exploit this information:

1. Phishing using geolocation
By determining your location, criminals can personalize phishing messages. For instance, if you're at a resort, you might not ignore a message supposedly from emergency services warning of dangerous weather conditions in the area.

2. Physical threats
Criminals can locate server centers or critical infrastructure and plan physical intrusions.

3. Espionage and surveillance
Malicious actors can use geodata to track people or organizations, monitor their movements, connections, habits, and even plans to exploit this information for their gain, such as crafting more convincing social engineering attacks or blackmail.

Overall, the use of geospatial intelligence by criminals poses a severe threat to data security, personal information, and critical infrastructure.

Law enforcement and GEOINT

On the flip-side, law enforcement agencies use GEOINT for investigations and apprehending criminals. For example, in 2019, Sacramento authorities arrested a drug dealer who sent potential buyers photos of marijuana on his hand. The fingerprints visible in the photo led to his identification. 

Photographs can indeed serve as evidence in criminal cases. In spring 2023, a data leak from the Pentagon put U.S. National Guard member Jack Teixeira under suspicion. An investigation revealed that the leaked photos were taken in his home, as the edges of the photographs matched the interior.

The most frequent method of geospatial intelligence is analyzing images or videos to determine their location. Almost anyone can conduct basic geospatial intelligence using the internet and various services. For example, a jealous wife might deduce from her husband's social media photos that he is not on a business trip but visiting a lover. 

Tools and services for GEOINT

Various services and tools are used for collecting data from open sources in geospatial intelligence. Here are some examples:

• Google Maps. A web mapping platform from Google offering satellite photos, aerial photography, street maps, interactive street views in 360°, and real-time traffic conditions.

• OpenStreetMap. An open collaborative project to create a free editable geographic database of the world.

• Soar Earth. A service for collecting and exploring satellite images, aerial photographs, and drone images.

• GeoHack Tools. This service provides a list of OSINT resources for the selected area on a map, including maps/satellite images, photographs, real-time weather, flight and maritime tracking, railways, peaks, and even fitness device data.

The range of geospatial intelligence tools is vast and continually expanding.

Final thoughts — protecting oneself 

As we have explored, even innocent photos shared on social media can be exploited by malicious actors, leading to severe consequences such as unauthorized access, blackmail, or even physical threats. To safeguard against these threats, it is essential to:

1. Be vigilant with personal information
Avoid sharing sensitive data in photos, such as login credentials or identifiable locations, that can be exploited by criminals.

2. Control privacy settings
Regularly review and adjust the privacy settings on social media platforms to limit the visibility of your posts to trusted individuals.

3. Use geotagging wisely
Disable geotagging on your devices when sharing photos publicly, as location data can be a significant security risk.

4. Leverage security tools
Utilize available security tools and services to monitor and protect against unauthorized use of geospatial data.

By taking these proactive steps, individuals and organizations can better defend themselves against the growing threats posed by the misuse of geospatial intelligence.

Every year, blockchain technology unveils new possibilities in the realm of digital transactions and decentralized applications. One of the latest additions to this ecosystem is the smart account—advanced accounts capable of automatically performing predefined functions and operations.

Imagine a digital wallet that automatically allocates funds among various investment portfolios based on predetermined rules or market conditions. Or consider a smart contract managing the supply of goods in real-time, based on demand and supply.

While smart accounts offer unprecedented flexibility and automation in managing cryptocurrencies, they also introduce unique security challenges that must be addressed to protect valuable digital assets and ensure the stability of decentralized systems.

What is a smart account?

Before delving into security issues, let’s clarify what smart accounts are and their role in the blockchain ecosystem. In traditional blockchains like Bitcoin, accounts are addresses linked to specific balances and transactions. However, smart accounts, as seen on platforms like Ethereum, have far broader functionality.

Smart accounts are unique accounts tied to executable code known as smart contracts. These contracts define the conditions under which the smart account can perform certain actions, such as transferring funds, performing computations, or interacting with other contracts. For instance, a smart account could be programmed to automatically send monthly rent payments from your cryptocurrency funds.

Unlike regular accounts that merely hold funds, smart accounts are autonomous agents capable of making decisions and performing complex operations based on embedded logic. It’s akin to a bank account that can independently transfer funds at specific intervals and under certain criteria.

Security issues of smart accounts

The unique security challenges of smart accounts are a significant concern, especially as protecting digital assets in the dynamic blockchain environment becomes critically important with the mass adoption of cryptocurrencies. Key security issues include code vulnerabilities, cyberattacks, and problems with access management and permissions. Any bugs or vulnerabilities in the code can have catastrophic consequences, such as the Genesis DAO project’s loss of $50 million in 2016 due to a smart contract vulnerability.

Several high-profile blockchain security breaches involving smart contracts have raised serious concerns, particularly among those actively engaged with blockchain technology. For instance, the infamous DAO hack led to the Ethereum network's hard fork, resulting in a new version of the blockchain—Ethereum Classic.

Once a smart contract is deployed on the blockchain, its code becomes immutable, making it extremely difficult to correct errors and vulnerabilities. This underscores the importance of thorough testing and code auditing before deployment. Otherwise, mistakes can lead to disastrous outcomes, as seen with CryptoKitties and Cryptozombies, where bugs in smart contracts resulted in the loss of valuable digital resources.

Best practices for smart account security

Given the risks associated with smart accounts, it’s crucial to follow best security practices throughout the lifecycle of smart contracts. Security should be an integral part of the smart contract design process, with careful consideration of contract logic, access structures, key management, and other critical aspects. For example, MakerDAO implemented a multi-tier permission structure and voting mechanism for managing its collateralized stablecoin system with security in mind.

Secure development of smart contracts involves using formal verification methods and proofs to ensure code correctness, engaging independent experts to audit the code before deployment, and applying secure programming patterns and standards, such as OpenZeppelin and Solidity Security Best Practices. Even after deployment, continuous monitoring of smart contract security is essential, as new threats and vulnerabilities can emerge at any time.

The future of smart account security

As blockchain and smart contract technologies evolve, new approaches and tools are emerging to enhance smart account security. AI and machine learning are being used for automatic vulnerability detection and error identification in smart contract code. Zero-Knowledge Proofs (ZKPs) are maintaining transaction privacy, and Secure Multi-Party Computation (MPC) is protecting confidential data by allowing computations on encrypted data without revealing the data itself. Formal verification provides mathematical proof of smart contract code correctness.

While quantum computers are still in early development stages, they may pose a future threat to the cryptographic algorithms used in blockchains. Malicious actors with sufficiently powerful quantum computers could potentially break traditional cryptographic systems used in blockchains. Smart contract developers should monitor this development and adapt their security systems using quantum-resistant algorithms.

Open-source communities play a crucial role in raising smart contract security standards. Collaboration, knowledge sharing, and tool improvement contribute to a more secure ecosystem. Examples of such communities include OpenZeppelin, the Ethereum Security Community, and Ethereum Cat Herders.

Education and awareness in smart account security

Ensuring the security of smart accounts involves education and awareness. This includes training developers, auditors, users, and other blockchain ecosystem participants on security best practices, threats, vulnerabilities, and prevention methods.

Smart contract developers should be well-versed in secure programming principles, security threats, and prevention techniques. This includes understanding common vulnerabilities like buffer overflows, coding errors, and access management issues, as well as using tools and methodologies for detecting and fixing such vulnerabilities.

Smart contract security auditors should be trained in using specialized tools and methodologies to analyze smart contract code, identify vulnerabilities, and recommend fixes. They should also stay updated on the latest threats and trends in blockchain security.

Users of smart accounts and decentralized applications also play a crucial role. They should be aware of security risks and best practices. This can include training on the secure storage and use of private keys, understanding phishing risks and other fraud types, and using tools and services to monitor the security of their smart accounts.

Conclusion

Smart account security is critically important in the era of digital transactions and decentralized applications. From secure development and auditing of smart contracts to education and awareness, compliance with regulatory requirements and security standards, and continuous monitoring and evaluation of security—all these aspects are key to ensuring the security of smart accounts.

Cybersquatting, i.e., the registration of domain names similar to a trademark already owned by someone, has existed for about as long as the Internet itself. However, even today, many companies are new to encounters with individuals who want to make money from the similarity of domains.

To successfully combat cybersquatters, it's important to consider their possible interest before registering a domain name for your website. What should you think about and what actions should you take? We explain in this article.

What is cybersquatting?

A person who registers domains that are consistent with someone else's trademarks is called a cybersquatter. Their non-cybersquatter counterpart, the common squatter, occupies a vacant building and asserts rights to it.

The principle remains the same, while the object is the humble ‘Domain’. Is there a company or brand name, but the domain consonant with it is somehow free? Then it needs to be occupied, sat on comfortably, and held until the owner who needs this domain name pays a ransom for it.

Simply put, cybersquatting is a type of entrepreneurial activity. Its goal: to be the first to find a potentially needed domain, register it for a standard symbolic value, and then resell it at a much higher price.

Types of cybersquatting

With many people wanting to make money on your website's domain or another company’s web resource, several types of cybersquatting exist:

Typosquatting or counting on user error involves registering a name one letter different from the original. If there’s a website example.com, registering exemple.com means some visitors will land there due to the typo. By displaying ads before they realize their mistake, you can make money.

Branded cybersquatting or counting on fame. A company has registered the domain example.ru, but it didn’t use example.com or example.biz. These will be registered by a cybersquatter.

Unsuccessful cybersquatting. An entrepreneur wants to launch a new product and announces his plans on social networks without registering the domain. The cybersquatter will get there first and the entrepreneur will have to pay more for the domain.

Cybersquatting with a trademark, which by law is worth more than the registered domain name. A site without a registered trademark finds a cybersquatter, who registers the TM for himself and, voilà, can now legally take away the domain through the court.

Drop domain cybersquatting involves domains not renewed in time by the rightful holder. Such a domain falls into a special section of the registrar's site, where the most promising quickly pass into the hands of entrepreneurs. When the owner remembers that the domain has not been renewed, it already belongs to another person.

Another phenomenon often confused with cybersquatting is called domaining. In this case, entrepreneurs use popular words in various industries without claiming a specific unique domain name. This is done expecting that someone wanting to create a new site will buy a favorable and easy-to-promote domain at a higher price.

For domains, words like business, photo, market, shop, and others are often used in various combinations. They also often take the surnames of famous people and names of settlements. The domain ivanivanov.ru could interest an entrepreneur with this name. Cityname.com with the name of a particular city is suitable for the site of its administrative structures or tourist portal.

How cybersquatters choose domains

Registering hundreds and thousands of unique domains with all kinds of typos and similar names is expensive. To keep his business afloat, it's important for a cybersquatter to choose successful combinations. To do this, entrepreneurs specializing in the resale of domain names often:

• Monitor situations in companies. For example, rumors of a merger between companies A and B. Therefore, a name containing fragments of each of their names is likely needed. Cybersquatters can register these before employees of the new large organization.

• Look for companies that already exist but don't have their own website yet. For example, those finding customers through social networks and other marketing channels. Domains consonant with their names are also bought for the future.

• Check the registration of a trademark on the company's domain name. The scheme of taking the domain from the owner is not always possible, but it still works.

Cybersquatting is real

Companies often believe those wanting to register a domain and resell it more favorably exist in a parallel universe. However, companies all over the world regularly encounter them.

Not all disputes over a domain arise for personal gain and fit the definition of cybersquatting. Sometimes the reason is the consonance in the names of two companies. For example, in 2014, the recruitment portal HeadHunter sued the Russia-based company HH&HR over the use of the domain hh-hr.ru. The court sided with the portal and ruled to seize the domain name in its favor. At that time, HeadHunter had no intention of using the domain name for commercial purposes.

But in 2017, Google sued Vitaly Popov over a case more akin to cybersquatting. The domain secret.ɢoogle.com was used to send messages saying "Vote for Trump" during the US election. The name differed from Google by just one letter. It started with an uppercase but small Latin "G", i.e., "ɢ", which in Unicode is denoted by the symbol 0262.

The battle between Italian clothing brand Lotto Sports Italy and Canadian David Dent for the domains LottoStore.com and LottoWorks.com ended with the latter winning. However, it was an epic two-part duel. The Canadian resident bought the two domains and planned to create gaming-themed websites. The clothing brand sued Dent and initially won. The court ordered the transfer of the domain names to the company. The Canadian appealed, and Lotto Sports Italy was eventually found guilty of reverse domain seizure. The company paid $237,000.

Cybersquatters and the law

No matter how dubious the activity of some squatters may seem, it doesn't negate the fact: cybersquatting is entirely within the legal field. It's not illegal to register domains and trademark names.

Yet the world is trying to combat cybersquatters. The main arbiter of domain disputes is the WIPO (World Intellectual Property Organisation), which unites 157 member countries. It has developed the UDRP — Uniform Domain Dispute Resolution Policy.

There are two ways for companies and brands that have faced domain name seizure: pay the amount demanded by the cybersquatter or go to court, where it's necessary to provide justification for their claims to the domain. For those slow to act, there's a third option: wait. If the domain name is rare and doesn't cause other market participants particular interest, the cybersquatter might eventually reduce the price. However, this is a path with unpredictable results.

Summing up: How to fight cybersquatting

It's important not only to know what cybersquatting is but also to think in advance about how to protect yourself from this phenomenon. A few simple rules will help:

• Check for a domain that matches the name of the company or brand before finalizing the name. Using an original, "off-the-beaten-path" name reduces the risk of domain disputes due to conflicts of interest.

• Don't publicize the brand or company name before the domain name is officially registered. Cybersquatters don't sleep! — Don't limit yourself to one domain when registering. It's better to choose several similar ones in different popular domain zones. This reduces the risk of someone creating dubious content on a similar domain.

• Register a trademark on the selected domain name immediately. This isn't a panacea, but in most domain disputes, its presence becomes a decisive argument for the court.

• Make timely payments for domain renewal to avoid dealing with squatters who quickly re-register drop domains to themselves.

If you can do all of this — it’s safe to say that you’ll be safe from the squatters!

A simple file or photograph shared with a colleague might encompass data that the sender didn't plan to divulge. For instance, a snapshot of a cat, besides the visible content, might inform the recipient about the location and time it was captured, and even the gadget utilized.

This holds true for social media platforms — an image uploaded online harbors details that might not only jeopardize the user but also disclose, perhaps, their whereabouts. Moreover, e-commerce transactions and various online actions create such digital traces. However, not everyone is acquainted with the concept of file metadata at present.

In this piece, we will elucidate the potential hazards of file metadata, ways to safeguard it, and how to individually eliminate undesired data embedded in transmitted images and other files.

The dangers of metadata

All our online activities — sharing images, and files, posting articles, curating music playlists, shopping, and so forth — create so-called digital traces besides the conveyed information. These are generated mainly due to metadata. Frequently, this reality is overlooked by the general populace, escalating the risk of unauthorized activities.

By analyzing, say, images on social platforms, a malefactor can deduce a victim's regular routes, favorite spots, and preferences. Utilizing this data, they might orchestrate a phishing scheme or employ social engineering tactics.

It's vital to note that corporations are equally, if not more, vulnerable compared to individual users when metadata falls into the wrong hands. Metadata can often assist criminals in decoding pilfered data. Hence, without comprehending the file's content and its potential use, cyber criminals resort to metadata, facilitating a quicker comprehension and monetization of the stolen assets. Alternatively, they might exploit metadata to ascertain the software utilized by a firm and plan a more targeted assault.

Metadata is generated automatically, without user intervention. Typically, it encompasses details about the creation time and place, attributes, author's remarks (if added to the file), and information about the software version used during creation. This data is quite personal and sensitive, given that in certain scenarios, metadata can narrate the history of file transfers and modifications.

The purpose of metadata

Primarily, metadata facilitates license restriction implementation and author identification. Furthermore, it aids websites and apps in organizing and recognizing content. And, for telecom operators, it helps in monitoring user engagement on specific platforms.

Any targeted marketing, audience segmentation based on preferences, location, habits, and professional sphere, stems from analyzing user metadata, or more precisely, the digital imprints left on social platforms and the broader internet. Metadata enables marketers to discern not only your smartphone model but also alarmingly accurate search queries.

Securing and erasing metadata 

Metadata is safeguarded similarly to conventional data, particularly concerning organizations rather than individual users. For the layman, the optimal approach is to erase metadata prior to file transmission to prevent the dissemination of unnecessary data and avoid leaving digital traces.

On an iPhone, it's straightforward to remove photo metadata:
• Launch the Photos application and choose the image you wish to strip of metadata
• Tap the "Share" symbol at the lower right corner and opt for the "Do not retain metadata" feature
• Press the "Done" button

To view a file's metadata on Android, Google Photos needs to be downloaded, and for deletion, a third-party application is required. Numerous choices are available in the store; it's advisable to scrutinize the description and additional features while selecting.

Additional tools and tips

Also, websites offering metadata removal services are excellent tools where you can effortlessly upload files prior to sending them, without the necessity to download anything or alter device settings. It should be noted that free versions impose file size restrictions, generally up to 5MB.

As per experts, the supreme strategy for metadata protection is to eliminate any metadata that might disclose sensitive details before dispatching a document anywhere. Moreover, if required, app software can be pre-configured to prevent metadata storage in documents altogether.

In the context of work-related files, metadata can be discarded when sharing them externally, but internally and when collaborating with contractors, metadata serves as a crucial component. Metadata functions as a historical record, aiding in understanding the preceding data, especially if older datasets are preserved.

Sensitive EXIF data encapsulates vital technical specifics about an image. It can reveal the camera or phone's brand and model, the creation time, and even the camera and flash configurations.

This data can be effortlessly deleted in Windows via Explorer. You need to launch it, navigate to the desired image, right-click on it, and choose "Properties," followed by the "Details" tab, where properties and personal information can be easily removed.

Conclusion

You can remove metadata using applications, online utilities, fundamental device configurations, and settings during transmission. However, remember that metadata can be beneficial, particularly concerning work-related matters. For instance, metadata can assist in identifying the software and editor used to create a file, its initial title, and creation date. This might facilitate file conversion or its utilization in a new system. Moreover, even a regular user might need to recall the time and place of file creation or image capture.

But it's essential to remember that if metadata isn't safeguarded, the same details can be accessed by an adversary and used against you. For instance, knowledge about the software version and other device specifics can be highly valuable for cyber criminals when choosing tools for.

2023 was characterized by an evolving array of cyber threats and a significantly broadened spectrum of digital vulnerabilities, pushing organizations to reassess and strengthen their cybersecurity infrastructures. Despite a widespread yearning for a break from the relentless tide of phishing, ransomware, and credential stuffing incidents, cybercriminals are gearing up to use their proven strategies from this period to orchestrate even more intricate and damaging campaigns in 2024. It’s become increasingly imperative for those in the cybersecurity realm to forecast and brace for the predominant challenges and trends that will define the cybersecurity landscape in 2024.

The following are key prognostications intended to serve as vital strategic insights for IT and cybersecurity professionals, aiding them in effectively prioritizing their efforts to navigate and mitigate the rapidly evolving threat landscape

Compromised credentials

The ongoing reliance on traditional usernames and passwords for access control and authentication has perpetuated the issue of compromised credentials. This has been a consistent weak spot, often exploited in cyberattacks. Detailed analyses of data breaches repeatedly pinpoint compromised credentials as a principal attack vector. Intriguingly, a study by the Identity Defined Security Alliance (IDSA) highlights that identity-related cyberattacks are both widespread (with 94% of respondents experiencing such attacks) and largely preventable (with a 99% prevention rate). Despite these alarming statistics, a significant number of organizations remain underprepared, lacking crucial identity-related security measures. This is particularly concerning given the rise of non-human identities stemming from digital transformations, such as in DevOps, cloud computing, and IoT (Internet of Things). Therefore, the expectation for 2024 is a continued emphasis on enhancing identity security, with organizations encouraged to intensify their implementation of Zero Trust models and decrease their dependency on traditional password-based systems.

Ransomware

Ransomware has proven to be a lucrative venture for cybercriminals, who exploit vulnerabilities within organizations to execute devastating attacks. Examples of these include high-profile breaches involving entities like the Kansas Court System, Yamaha Motors, and Western Digital. The emergence of Ransomware-as-a-Service has simplified the process of launching such attacks. Over the past year, ransomware tactics have evolved into complex extortion schemes, involving not just data encryption but also data exfiltration and threats of public disclosure if ransoms aren't paid. This trend was exemplified by the Alphv/BlackCat ransomware group's SEC complaint against MeridianLink. With new SEC disclosure regulations mandating prompt reporting of major cybersecurity incidents, such tactics are expected to gain even more traction. Therefore, enterprises are advised to enhance their ransomware preparedness, with a specific focus on the recovery of endpoints and essential infrastructure like Active Directory.

Hacktivism amidst global conflicts

The intersection of global conflicts and the upcoming 2024 Presidential elections in the United States is expected to create a fertile environment for hacktivism. Hacktivists, often self-identified as defenders of free speech, may seek to disrupt the controlled flow of information during times of conflict or elections by exposing sensitive data or initiating cyberattacks. This could lead to a blurring of lines between state-sponsored hacking and independent hacktivist activities. The role of hacktivists in influencing public opinion through various cyber operations, including the potential use of deepfake technologies, is expected to be significant in 2024.

Vulnerability management 

In response to the increasing exploitation of zero-day vulnerabilities by cyber adversaries, the White House's National Cybersecurity Strategy, released in March 2023, has redirected focus towards organizations' responsibility to secure their software. This strategy underscores the importance of comprehensive vulnerability management, which involves identifying, assessing, prioritizing, and mitigating security vulnerabilities. This increased emphasis on liability for independent software vendors is anticipated to drive technological advancements in vulnerability management tools and bring renewed attention to this critical aspect of cybersecurity.

Transformation in security awareness training

The realm of security awareness training is poised for a significant transformation in 2024. With the widespread adoption of generative artificial intelligence in the sphere of cyber threats, traditional training methods are becoming obsolete. Future training programs are expected to integrate continuous breach and attack simulations (BAS) to test and enhance the effectiveness of user-focused controls. These programs will also likely focus on equipping software developers with secure coding practices to preemptively address vulnerabilities.

Conclusion

In summary, the year 2024 emphasizes the crucial need for a delicate balance between robust cybersecurity measures and the resilience to adapt to cyber threats. As IT and security professionals prepare for the challenges ahead, prioritizing the continuous visibility, protection, and management of the entire digital attack surface is paramount. Protecting mission-critical assets and developing the capability to anticipate, withstand, recover from, and adapt to various cyberattacks will remain at the forefront of effective organizational cybersecurity strategies.

Of course, losing access to your Google or Gmail account is going to be upsetting. If you've forgotten your password, or if someone has hacked into your account and changed it, Google provides a list of actions that you may take to regain access to your account. Indeed, they may come in handy at times, but the methods of password recovery for Google accounts tend to change from time to time and relying on them as a fallback is never a good idea.

Not only have we provided all the necessary links in the “Password recovery” section down below for those who have lost access to certain accounts, but we’ll today be focusing on what can be done to ensure you never lose access to your account again. Here are some things to consider:

Regularly backup your data

If you have a current backup of your data, it will be less of a blow if you ever lose access to your account. Takeout is the name Google has given to the feature that allows you to download your data. You may download all of the data from all of your Google applications, or just part of the data from some of them. You might even decide to download the data from a single app, such as Gmail, from your Google account.

For each sort of data, the download formats are different. For example, MBOX files may be imported to Gmail or most other email services and applications.

Keep your old passwords

Keep a copy of your old passwords in case you forget your current one. Google uses this method to verify your identity if you ever lose your password. In the event that you haven't updated your password in a while, you may not be able to recall your old password. It's a good idea to maintain a copy of your previous Google passwords in a secure place when you change your password.

When using a password manager such as Passwork, you can keep track of your previous passwords. Because of that, we strongly recommend using one. When you establish a new password on an app or website, most password managers only allow you to update the current entry; however, with a password manager, you may create a new password and then go back and change the name of the old one to something like "Gmail — old password". By the way, this is also a problem with Apple Keychain — when you change your password, it asks whether you would like to update your old password. You’ll obviously press “Update”, and bam, your previous password is lost in the void. So keep an eye on that.

Why is this important? Well, as we’ve hinted at, Google asks you to enter the previous password in some cases as a fallback plan.

Fill in the recovery info

Google provides you with many ways to recover your password:

1. Go to your Google account and choose "Security" from the left-hand column
2. Scroll all the way down to "Ways that we can verify that it’s you"
3. Fill them in
4. PROFIT

Now, Google will use those options to recover your password when needed, or just to verify it’s you when weird login behaviour is detected. Among all the options, the ‘Recovery phone’ is the most convenient one — trust me, you’ll forget that ‘Security Question’ in just a few days. ‘Recovery email’, to be honest, isn't secure enough — we, Earthlings, tend to use weak passwords, so your account might be compromised if a hacker manages to guess your ‘NicknameDateOFBirth’ password.

Remember the day you registered

If everything else fails, Google may ask you to provide an estimated date of when you created the account. The best way to get this date is by searching for a Gmail welcome email.

To locate the welcome email, go to the ‘All Mail’ folder on your computer (to see it, you may need to click ‘More’ to expand the folders). You may also hover your cursor over the page information in the upper right-hand corner and choose ‘Oldest’.

This will move the email you received first to the top of the list. If, on the other hand, you imported non-Gmail emails into your inbox from before 2004, the welcome email will not appear at the top of the inbox hierarchy. Also, if you haven’t imported all of your emails, you’ll encounter some problems.

The email may also be found by searching for "welcome," "Gmail team," "[email protected]," or "[email protected]," among other similar words and phrases.

However, when I personally tried it, I couldn't find it. This is because I delete all the mail on my account once a year. For people like myself, there’s a weird hack — your POP settings might show the date on which you created your Gmail account.
To access them, click the gear icon in the top right-hand corner, select See all settings, then click Forwarding and POP/IMAP.

Look for the Status line in the POP download section. If you're fortunate, you'll come upon the following information:

“Status: POP is enabled for all mail that has arrived since [Here is your date]”

Important:

If you’ve ever changed your POP settings, the date on which you created your Gmail account won’t be shown.

Password recovery

There’s only one place where you can recover your password — it’s this “Google Recovery” page. Everything else is likely phishing scams. The only other alternative option, in case of an adversary like losing your password, is the “Can’t sign into your Google Account” page.

Basically, you should follow the instructions on screen and pray to Google's mothership that hope shall be restored.

If your prayers haven’t been heard, and all pages cycle through a loop with a “Please try again” message, visit the “Tips to complete account recovery steps” page — it helped me several times to understand exactly what Google wants from me.

The last page you can visit, if everything else fails, is “Create a replacement Google Account”.

Conclusion

If you have important data stored on any cloud: Gmail, Google Drive, Docs, etc. — back them up using offline storage. Use two-factor authentication to always keep your mobile phone as a recovery option. Keep hold of your password change history and remember the date you registered your account.

If you’ve ever set up a wireless router on your own, you’ve probably heard of WPS. You might come across this term in the router’s configuration menus or see it on the backside of your router — but do you know what WPS actually means and how it works? If you can’t answer these questions yourself, then you’re in the right place.

What is WPS?

WPS stands for WiFi Protected Setup. It’s effectively a wireless network security standard that speeds up and simplifies the process of connecting your device with a router. It helps to do it quickly without entering a Wi-Fi password. To enable WPS you should find a tactile button located on the backside of your router or switch it on in the configurations menu of the router. When you turn it on, WPS mode allows you to connect your various devices to your router using the WPS password, also known as the WPA-PSA key.

In fact, WPS is not responsible for the Wi-Fi connection at all. It’s designed solely to send the connection data between the router and the wireless device. Remember, that’s an important distinction.

WPS was an idea of the nonprofit ‘Wi-Fi Alliance’. The alliance is effectively an association of the largest companies that create computers and Wi-Fi devices. More than 600 members take part, including companies such as Microsoft, Samsung, and Intel. Alliance was founded in 1999 to promote Wi-Fi technologies and certificate Wi-Fi products around the world. This standard was created in 2007 to simplify the connection process and since that time, most Wi-Fi systems around the world have adopted it.

How does WPS work?

If you want to connect your wireless device, you have to know the password to the Wi-Fi network. This process isn’t difficult but it takes some time to get the essential data. WPS makes it easier and a bit quicker.

There are some different ways to do it. First of all, WPS can be a workaround for connecting to Wi-Fi without a password. To do so, you should hit the WPS button on your router to enable device detection. Then, take your device and choose the network you need to connect to. The connection will be immediately available and the system won’t ask you to enter the password.

Some wireless electronic equipment like printers also has a WPS button that can be used to make rapid connections. All you have to do is to push both buttons, on the device and on the router, to get access to the wireless network. You don’t need to enter any data here, as the WPS delivers the password automatically. Also, that device will be able to connect to the same Wi-Fi router without pushing WPS buttons in the future as the password will be remembered.

The other option requires one to use the eight-digit PIN code. When WPS is enabled on a router, a PIN code is produced automatically. The WPS PIN can be found on the WPS setup page. Some devices that lack a WPS button will require the PIN. If you enter the wireless network, they verify themselves and connect to it.

The last option also can be done by using that eight-digit PIN. Some devices do not have the WPS button but also support WPS, so they will produce a client PIN that will be used by the router to connect the device to the network. You should just enter the PIN in the settings of your router to get access.

Unfortunately, methods that require using a PIN code don’t have any benefits in the speed of the connection process. You spend the same amount of time entering the router’s password and the WPS PIN, so you should just choose the way that’s more comfortable for you.

Which devices work with WPS?

WPS is supported by a wide range of devices, most commonly, wireless routers. However, you can also find a WPS button on wireless printers, Wi-Fi Range Extenders and Repeaters, which commonly provide WPS capabilities as well. Finally, the WPS functionality is available on a few higher-end laptops, tablets, smartphones, and 2-in-1 devices, where it’s usually implemented via software rather than physical buttons.

What are the advantages and disadvantages of WPS?

Despite the fact that WPS is embedded in most Wi-Fi equipment, the benefit of this standard is still a controversial issue. Some professionals opt for using it as it makes the connection to the router easier and quicker while others opt against it as WPS mitigates the security of the connection process.

Advantages:

1. It's quick, especially if both the router and the client device have the WPS button.

2. It's simple and requires no technical knowledge. There is no more primitive way of connecting Wi-Fi than pressing the WPS button on both the router and the client device.

3. Support is relatively strong. WPS is supported by all routers and most networking devices. WPS can also be used to establish rapid Wi-Fi network connections on the most common operating systems like Windows, Android, and Linux.

Disadvantages:

1. It isn't really safe. WPS connections using PINs appear to be particularly sensitive to brute-force attacks. A successful WPS attack allows an attacker to obtain access to your Wi-Fi network, and disabling WPS is the only viable remedy.

2. WPS can be used by anyone who has physical access to the router. So any person who is aware of the router’s location can connect it without your permission.

3. WPS is not supported by Apple. You can't connect to Wi-Fi using WPS if you have a Mac, an iPhone, or an iPad. This is because Apple has determined that WPS is insufficiently secure, and thus WPS isn’t not supported by any of the devices.

Conclusion

As we’ve found out, the WPS network’s security standard has both benefits and limitations. On the one hand, it helps us to avoid remembering the Wi-Fi password and connect quickly. On the other hand, WPS is not secure enough to foster user confidence across the board. So, it’s up to you to decide on using WPS or not. In any case, you can disable the function at any time you want by simply switching off the WPS button.

In Passwork 6.3, we have implemented numerous changes that significantly improve organization management efficiency, provide more flexible user permission settings, and increase security:

• Administrative rights
• Hidden vaults
• Improved private vaults
• Improved settings interface

Administrative rights

Available with the Advanced license

Now there is no need to make users administrators in order to grant them specific administrative rights. This option is a response to one of the most frequent requests from our customers.

Administrators can grant only those rights or permissions that are necessary for users to fulfill their duties and flexibly customize access to settings sections and manage Passwork. For instance, you can grant employees the right to create and edit new users, view the history of user activity, track settings changes, while restricting access to organization vaults and System settings.

You can configure additional rights on the Administrative rights tab in User management. There are four settings sections to flexibly customize Passwork for your business:

General

In this section, you can grant users access rights to manage all existing and new organization vaults, view the history of actions with settings and users, access license info and upload license keys, view and modify the parameters of SSO settings and Background tasks.

User management

In this section, you can grant users access rights to view and modify User management parameters. This includes performing any necessary actions with users and roles, such as creating, deleting, and editing users, changing their authorization type and sending invitations.

System settings

In this section of settings, you can grant users the right to view and modify specific groups of System settings.

LDAP settings

In this section, you can grant users the right to view and modify LDAP parameters which include adding and deleting servers, registering new users, managing group lists, viewing and configuring synchronization settings.

Activity log

The event of changing user administrative rights has been added to the Activity log. All changes are now recorded in the Activity log, that includes the users who initiated such changes as well as each setting that was modified with its previous and current values.

Interface improvements

Users with additional administrative rights are marked with a special icon next to their user status.

Some items remain unavailable until the necessary settings have been activated. When hovering your cursor over such items, a tooltip with information regarding dependent settings will be displayed.

Hidden vaults

In the previous versions of Passwork only organization administrators were able to hide vaults. Also, only organization vaults could be hidden. In this new version, all users can hide any vaults. Hiding makes vaults invisible only to the users who choose to do it and does not affect others.

Hidden vault management is now carried out in a new window, which is available directly from the list of vaults. You can view the list of all available vaults and customize their visibility there.

Private vault improvements

Displaying private vaults in User management

Besides hiding private vaults, employees with User management access can now see all vaults which they administer (including private vaults). The new feature which makes it possible to add users to private vaults has also been added to User management.

Logging of events in private vaults

Private vault administrators can view all events related to their vaults in the Activity log.

Other changes

• Fixed an issue which prevented users from changing their temporary master password
• Fixed an issue which prevented users from setting the minimum length for authorization and master passwords
• Fixed an issue in User management which made administrator self-deletion possible
• Minor improvements to the settings interface

Self-signed certificates are widely used in testing environments and they are excellent alternatives to purchasing and renewing yearly certifications.

That is of course if you know how and, more importantly, when to use them. Remember, that A self-signed certificate is not signed by a publicly trusted Certificate Authority (CA). Self-signed certificates are considered different from traditional CA certificates that are signed and issued by a CA because self-signed certificates are created, issued, and signed by the company or developer who is responsible for the website or software associated with the certificate.

You are probably reading this article because for some reason, you need to create a self-signed certificate with Windows. So, we’ve tried to outline the easiest ways to do that. This article is up-to-date as of December 2021. By the way, we’re referring to Windows 10 for all the following tutorials. As far as we know, the processes for Windows 11 are identical.

So what are our options?

Using Let’s Encrypt.

These guys offer free CA certificates with various SAN and wildcard support. The certificate is only good for 90 days, but they do give an automated renewal method. This is a great alternative for a quick proof-of-concept. Other options would require more typing, for sure.

But this option works only if you want to generate a certificate for your website. The best way to start is by going to Getting Started, the instructions thereafter are very easy to follow.

Other one-click option:

We’ve reviewed different online services that allow you to easily generate self-signed certificates. We’ve sorted them from one-click to advanced, and the first one is:

Selfsignedcertificate.com

Just enter your domain name — and you are ready to go:

Getacert.com

Fill out the following fields:

Press “Next”, then confirm your details, and get your certificate:

It’s that easy!

Сertificatetools.com

Among the online services that allow you to generate self-signed certificates, this one is the most advanced; just look at all available options to choose from:

Now let’s continue with offline solutions, that are a bit more advanced:

PowerShell 4.0

1. Press the Windows key, type Powershell. Right-click on PowerShell and select Run as Administrator.

2. Run the New-SelfsignedCertificate command, as shown below.

$cert = New-SelfSignedCertificate -certstorelocation 
cert:localmachinemy -dnsname passwork.com

3. This will add the certificate to the locater store on your PC. Replace passwork.com with your domain name in the above command.

4. Next, create a password for your export file:

$pwd = ConvertTo-SecureString -String ‘password!’ -Force -AsPlainText

5. Replace password with your own password.

6. Enter the following command to export the self-signed certificate:

$path = 'cert:localMachinemy' + $cert.thumbprint 
Export-PfxCertificate -cert $path -FilePath 
c:tempcert.pfx -Password $pwd

7. In the above command, replace c:temp with the directory where you want to export the file.

8. Import the exported file and deploy it for your project.

Use OpenSSL

1. Download the latest OpenSSL windows installer from a third-party source;

2. Run the installer. OpenSSL requires Microsoft Visual C++ to run. The installer will prompt you to install Visual C++ if it is already not installed;

3. Click Yes to install;

4. Run the OpenSSL installer again and select the installation directory;

5. Click Next;

6. Open Command Prompt and type OpenSSL to get an OpenSSL prompt.

The next step would be to generate a public/private key file pair.

1. Open Command Prompt and create a new directory on your C drive:

C: >cd Test

2. Now go to the new directory:

C: Test>

3. Now you need to type the path of the OpenSSL install directory followed by the RSA key algorithm:

C: Test>c:opensslbinopenssl genrsa -out privkey.pem 4096

4. Run the following command to split the generated file into separate private and public key files:

C: Test>c:opensslbinopenssl ssh-keygen -t rsa -b 4096 -f privkey.pem

Once you have the public/private key generated, follow the next set of steps to create a self-signed certificate file on Windows.

1. Go to the directory that you created earlier for the public/private key file:

C: Test>

2. Enter the path of the OpenSSL install directory, followed by the self-signed certificate algorithm:

C: Test>c:opensslbinopenssl req -new -x509 -key privkey.pem -out cacert.pem -days 109

3. Follow the on-screen instructions;

4. You need to enter information about your organization, region, and contact details to create a self-signed certificate.

We also have a detailed article on OpenSSL – it contains more in-depth instructions on generating self-signed certificates.

Using IIS

This is one of those hidden features that very few people know about.

1. From the top-level in IIS Manager, select “Server Certificates”;

2. Then click the “Create” button on the right;

3. This will create a self-signed certificate, valid for a year with a private key. It will only work for “localhost”.

We hope this fruit bowl of options provides you with some choice in the matter. Creating your own self-signed certificate nowadays is trivial, but only until you begin to understand how they really work.

Our option of choice is, of course, OpenSSL — after all, it is an industry-standard.

Are you having trouble remembering your passwords or accessing your account? Perhaps you’re stressing out that you may have been hacked? Well, in any case, restoring your Facebook account utilising reliable Facebook account recovery solutions shall be covered by this article, so buckle up!

In order to regain access to your Facebook account, you can use one of several automated methods. Many are based on the information you provided when you set up your account, which isn’t helpful if you can’t remember the most important piece of information you provided when you set up the account — your password. Also, some information will be out of date, like your recovery phone number or your active email address.

And even if all methods listed below fail, we’ve got an alternative for you right at the very bottom of the article.

Firstly, make sure that you aren't still logged into Facebook somewhere else!

Android and iOS Facebook apps, as well as mobile browsers may all be used to access the site, so you might be logged in on them.

If you are logged in, you can ‘recover’ your account by simply changing the password, and it can be done without a confirmation reset code!

But if you are not logged into Facebook on other devices or browsers — try Facebook's Default Account Recovery Methods.

If at all feasible, log into your Facebook account using the same internet connection and computer or phone that you've used on a regular basis in the past. If Facebook detects your network and device, you may be able to reset your password without having to provide any extra information to Facebook. But first and foremost, you must authenticate your account.

Find and recover your account by providing contact information

The best option is to directly go to the Facebook Recovery Page.

To sign in, enter an email address or phone number that you previously associated with your Facebook profile. When looking for a phone number, test it both with and without your country code, for example, 1, +1, or 001 for the United States; all three variants should work just fine. Even if it doesn't explicitly say so, you may use your Facebook credentials to log in — instead of your mobile number or email.

Your profile will be summarised once you have successfully identified your account, as seen in the screenshot below. Please double-check that this is indeed your account and that you still have access to the email address or phone number mentioned before proceeding. The option of choosing between email or phone recovery may still be available to you.

If everything appears to be in order with the contact information that Facebook has on file for you, though, click Continue. A security code will be sent to you by Facebook.

Retrieve the code from your email or phone (depending on whatever method you used), input it, and rejoice in the knowledge that you have regained access to your Facebook profile.

At this point, you have the option of creating a new password, which we highly advise you to do.

If you don't receive the code via email, check your spam folder, or make sure you can receive text messages from unknown senders if the code doesn't arrive to your mobile.

If you are still unable to receive the code, choose Didn't get a code? from the drop-down menu. You can return to the previous screen by clicking the X in the bottom-left corner of the Enter Security Code box.

Maybe you'll get lucky and discover that you don't, in fact, have access to the account at all!

Log back into your Facebook account

You should immediately reset your password and update your contact information if you have regained access to your Facebook account after a suspected hijacking.

To keep your Facebook account safe, follow two simple rules. Don't forget to get rid of any email addresses or phone numbers that you no longer have access to. Also, enable two-factor authentication on all of your social media accounts in order to prevent a loss of access in the future.

Don’t forget, the Facebook Help Community is a great place to find answers to your issues.

If all else fails, creating a new Facebook profile might not be as bad as you think

Over the past few years, we've received a large number of letters from users who were unable to regain access to their Facebook accounts, despite following each and every one of the instructions listed above.

Typically, their contact information was out of date, the recovery codes offered by Facebook were ineffective, or the corporation never responded to their request for identification verification. And at that point, you’re pretty much out of options.

You have to accept the fact that you must move on. Even though it's painful, you must learn from your mistakes and register a new user account.

Always include legitimate contact details, don’t forget to up the security on your Facebook account, and completely re-create your profile from the ground up. Despite the inconvenience, it’s a better option than doing nothing. Not to mention, you won’t have any of those embarrassing old photos, and you can only add people as friends that really matter to you now.

In Passwork 6.2 we have introduced a range of features aimed at enhancing your security and convenience:

• Bin
• Protection against accidental removal of vault
• Protection against 2FA brute force
• Accelerated synchronization with LDAP
• Improved API settings
• Bug fixes in role management

Bin

Now, when deleting folders and passwords, they will be moved to the Bin. If needed, they can be restored while preserving previously set access permissions. Vaults are deleted without being moved to the Bin — they can only be restored from a backup.

Who can view deleted passwords and folders in the Bin?

Inside the bin users can see the deleted items from those vaults in which they are administrators. For instance, an employee who is not an administrator of organization vaults will only see the deleted passwords and folders from his personal vaults when opening the Bin.

In addition to object names, the Bin also displays the usernames of people who deleted data. You can also see the initial directory name and the deletion date.

Object restoration

Objects from the Bin can be restored to their initial directory if it has not been deleted or moved. Alternatively, you can choose any other directory where you have edit and higher access levels.

When restoring deleted folders to their initial directories, user and role access levels will also be restored exactly as they were previously manually set in these folders. Other access permissions will be set based on the current permissions in the initial directory.

When restoring folders to a directory different from the initial, access levels will always depend on the current permissions in the selected directory.

Additional access to deleted passwords

If passwords have been shared with users, moving them to the Bin will remove them from the “Inbox” section, and any shortcuts or links to these passwords will become nonfunctional.

Restoring additional access

When restoring from the Bin, it is possible to regain additional access levels to passwords. Passwords that were shared with users will reappear in their “Inbox” section, access to passwords through shortcuts will be restored, and links that have not expired will become functional again.

Bin cleanup

You can delete selected items from the Bin or use the "Empty Bin" button to remove all items contained inside.

It's important to note that in the Bin you only see the items which were deleted from the vaults where you are an administrator. Objects from other vaults are not visible, and clearing the Bin will not affect them.

In future, the option to configure automatic Bin cleanup will be added.

Protection against accidental removal of vault

To confirm the deletion of a vault, you now need to enter its name. It will be permanently deleted along with all the data inside. Additionally, if there are passwords or folders from this vault in the Bin, they will also be removed.

Protection against 2FA brute force

Protection against 2FA brute-force attacks has been added. After several incorrect attempts to enter the 2FA code, the user will be temporarily locked. The number of attempts, input intervals, and the lockout time are set in the config.ini file.

Other changes

• LDAP synchronization has been accelerated
• Descriptions of parameters and minimum allowable values for API token expiration time and API refresh token expiration time have been added to the API settings section
• Automatic assignment of "Navigation" to parent folders in role management has been fixed
• The issue when a vault administrator could not add roles to a vault and manage its permissions has been fixed
• The issue with showing additional access rights to passwords when moved to another vault has been fixed

Over the past decade, data has transitioned from mere information to a precious asset. Numerous enterprises thrive on data, while others crumble with its loss. Customer personal information, analytics, financial transaction records and more hold monetary value. Yes, there's an abundance of informational "clutter" around, but even amid hard-to-spot data, a skilled cybercriminal can discover a gold mine. 

The acceleration of information technology is rapid, with fresh information emerging and being processed every moment. Often, companies simply lack the time to sift the "wheat" from the "chaff" and, as a result, release sensitive data, like customers' home addresses for delivery, into the open. 

Most firms have mastered data collection, some have ventured into processing it, and a fewer number into analyzing it, but not all have grasped how to safeguard it. In this article, we’ll explore what qualifies as sensitive data, how to shield it, and the primary blunders made while handling sensitive data.

What sets apart ordinary data from sensitive data? 

With the trend of data accumulation in the market, corporations have embraced it wholeheartedly. This opens up numerous avenues for growth, business broadening and optimization, and introducing new offerings to the market. For instance, by scrutinizing customer conduct, you can present them with the products they need at the opportune moment. Or, simply, knowing customers' birthdays, send a discount coupon as a present, encouraging a new purchase. The possibilities are myriad, and they stem from entirely diverse data types. That's why enterprises amass data even before understanding its use. It's for the just-in-case scenario. 

Similarly, it's not always feasible to instantly determine the significance of data and the extent of protection required. Some opt for overcaution, storing data securely from the outset, while others leave it in public view, thus risking it. The sensitivity of data can be gauged by asking — what’s the fallout if it’s pilfered? 

Two outcomes exist. Nothing occurs — the data isn't sensitive. The offender, directly or indirectly, could inflict harm on the business or customers. For instance, by pilfering personal data, like full names and phone numbers, and releasing them online, the company’s reputation takes a hit. Or, by stealing an individual’s data — their address, purchasing tendencies, and, say, date of birth, orchestrate a social engineering assault.

Sensitive data encompasses information that could potentially jeopardize its possessor. For regular folks, it’s mainly personal and financial data, medical details, relationship data, personal visuals, and data on preferences. For companies, it includes internal business records, customer and employee databases, confidential documents, market evaluations, and the like. 

Recognizing sensitive data 

The theft or exposure of sensitive data undermines a company's customer privacy, triggers financial setbacks, and could even threaten an organization’s security. Hence, distinguishing sensitive personal data from common data is crucial. This involves carrying out a data classification and risk assessment. 

This could encompass evaluating potential damage in case of a data breach, as well as examining legal mandates for specific data types. Primarily, anything related to sensitive information and personal data should be guarded. However, the task of identifying data types doesn’t conclude here. For instance, trade secrets can be shielded under 21 orders or at your discretion, but personal data must be classified and shielded by law. Information security experts opine that to pinpoint sensitive company data, the IS division, along with representatives from various sectors — accounting, legal, HR, and marketing — should formulate guidelines to identify sensitive information. The primary focus here would be potential financial or reputational harm from information leakage. Yet, the potential threat indicator of a data breach may not always be objective. Numerous cyber incidents involving social engineering demonstrate that even seemingly harmless data about a person can be utilized to perpetrate a crime.

Key blunders in handling sensitive data 

Both enterprises and users can be culpable for sensitive data leakage. On the corporate side, the usual culprit is a basic disregard for information security norms. For instance, unprotected corporate networks, operating on outdated operating systems, or absence of antivirus protection. On the user side — unawareness of cyber hygiene norms and a lack of understanding of what data might be sensitive. Common errors enabling sensitive data leakage: 

• Inadequate password and account safeguards
• Lack of data categorization within the firm
• Improperly set up security systems
• Absence of data encryption
• Employees are untrained in cyber hygiene 

Moreover, information is often undervalued by both corporations and individuals. For instance, a person may deem their passport information crucial but be indifferent about sharing their health information on social networks. Like any other domain of information security, elementary measures are paramount. For example, remembering updates, prompt training of staff in cyber hygiene, and employing protective software.

Conclusion 

The subject of sensitive data is steadily gaining traction, as only in recent times have assailants learnt to actively exploit personal or corporate data to commit offenses. For larger and more technologically advanced companies, the issue is being addressed at a more sophisticated level, as they have not only learnt how to analyze and segment data but also how to defend it. However, there's another facet to consider - the company service users themselves. They may possess minimal awareness of the worth of their personal data and trigger leaks.

In 2024, the digital finance landscape is increasingly challenged by sophisticated forms of fraud, particularly carding. This type of credit card fraud, involving the unauthorized use of stolen card information, poses significant risks to both individuals and financial institutions. This comprehensive exploration delves into the mechanisms of carding, its evolutionary trajectory in the realm of financial fraud, and the multi-faceted strategies being employed to protect bank accounts in this digitally-dominated era.

Understanding carding

Carding is a complex process initiated by the illicit acquisition of credit card information. This can occur through various methods: 

• Sophisticated hacking operations that breach financial databases
• Phishing schemes designed to deceive individuals into divulging their details
• Large-scale data breaches at major retailers or financial institutions

Once fraudsters acquire this data, they test it to verify its legitimacy and then use or sell it for unauthorized transactions, often leveraging the anonymity of the dark web. The speed and stealth with which carding operations are conducted make them a particularly pernicious and challenging form of financial fraud to counteract.

The evolution of financial fraud

Financial fraud has undergone a significant transformation over the years.

In the current digital landscape, where we frequently engage in conversations without visual context, our reliance on audio cues to verify the identity of our conversational partners has intensified. Our brains have developed an astonishing ability to discern and recognize the intricate details in someone’s voice, akin to an auditory signature that is unique to each individual. These vocal signatures, composed of elements such as pitch, pace, timbre, and tone, are so distinctive that we can often identify a familiar voice with just a few spoken words. This remarkable auditory acuity serves us well, but it is under threat by the advent of advanced technologies capable of simulating human voices with high accuracy—voice deep fakes.

What are deep fakes? 

The term 'deepfake' has quickly become synonymous with the darker potential of AI. It signifies a new era where artificial intelligence can manipulate reality with precision. Early deepfakes had their tells, but as the technology has progressed, the fakes have become almost indistinguishable from the real thing. 

The entertainment industry's experimentation with deep fakes, such as the lifelike replicas of celebrities in a TV show, serves as a double-edged sword. It showcases the potential for creative innovation but also hints at the perils of AI in the wrong hands, where the distinction between truth and fiction becomes perilously thin.

The creation of voice deep fakes is rooted in complex AI systems, particularly autoencoders, which can capture and replicate the subtleties of human speech. These systems don't just clone voices; they analyze and reproduce the emotional inflections and specific intonations that make each voice unique.

The implications are vast and varied, from actors giving performances in multiple languages without losing their signature vocal emotion, to hyper-personalized virtual assistants. Yet, the same technology also opens avenues for convincing frauds, making it harder to trust the unseen speaker.

The dangers of convincing voice deep fakes

Crafting a voice deepface is a sophisticated endeavor. It involves a series of complex steps, starting with the collection of voice data to feed into AI models. Open-source platforms have democratized access to this technology, but creating a voice deep fake that can pass for the real thing involves not just the right software but also an expert understanding of sound engineering, language nuances, and the intricate details that make each voice distinctive. This process is not for the faint-hearted; it is a meticulous blend of science and art.

The misuse of deepfake technology has already reared its head in various scams, evidencing its potential for harm. Fraudsters have leveraged these fake voices to imitate CEOs for corporate espionage, mimic government officials to spread disinformation, and even duplicate voices of family members in distress as part of elaborate phishing scams. These incidents are not simply one-off events but indicative of a troubling trend that capitalizes on the inherent trust we place in familiar voices, turning it against us.

The path that deepfake technology is on raises profound questions about the future of trust and authenticity. Currently, the most advanced tools for creating deep fakes are closely held by technology companies and are used under strict conditions. But as the technology becomes more accessible, the ability to create deep fakes could fall into the hands of the masses, leading to widespread implications. This potential democratization of deepfake tools could be a boon for creativity and individual expression but also poses a significant threat in terms of misinformation, privacy, and security.

The defense against deep fakes: a multifaceted approach

To tackle the challenge of deep fakes, a robust and varied approach is essential. Researchers are developing sophisticated detection algorithms that can spot signs of audio manipulation that are imperceptible to the human ear. Legal experts are exploring regulatory measures to prevent misuse. And educational initiatives are aiming to make the general public more aware of deep fakes, teaching them to critically evaluate the media they consume. The effectiveness of these measures will depend on their adaptability and continued evolution alongside deepfake technology.

Awareness is a powerful tool against deception. By educating the public on the existence and methods behind deep fakes, individuals can be more vigilant and less susceptible to manipulation. Understanding how deep fakes are made, recognizing their potential use in media, and knowing the signs to look out for can all contribute to a society that is better equipped to challenge the authenticity of suspicious content. This education is vital in an era where audio and visual content can no longer be taken at face value.

Navigating the ethical landscape of deepfake technology is critical. The potential benefits for creative industries, accessibility, and personalized media are immense. Yet, without a strong ethical framework, the negative implications could be far-reaching. Establishing guidelines and best practices for the responsible use of deepfakes is imperative to prevent harm and to ensure that innovation does not come at the cost of truth and trust.

Conclusion

As voice deep fakes become more advanced, they pose a significant challenge to the trust we place in our auditory perceptions. Ensuring the integrity of our digital communications requires not just caution but a comprehensive strategy to navigate this new terrain. We must foster a society that is equipped to recognize and combat these audio illusions—a society that is as critical and discerning of what it hears as it is of what it sees. It is a complex task, but one that is essential to preserving the fabric of trust that binds our digital and real-world interactions together.

Information security (IS) courses are needed not only for IS department employees and not even only for certain employees of a company but for everyone. Information security training in today's world, where virtually all areas of life have been digitized, should be on par with fire safety and other fundamental rules that employees are required to observe in the workplace.

Even the most ordinary employee today has access to corporate email or other means of communication within the company, as well as internal information systems and archives. If they do not know the basic rules of cyber hygiene or do not update them in a timely manner, they can become a springboard for attackers to access sensitive company data.

In this article, we will discuss the importance of cyber hygiene in the enterprise, why this knowledge needs to be updated, the pros and cons of in-house and third-party cyber security courses, and what should be included in a cyber hygiene course.

Why cyber hygiene training matters

Almost every aspect of modern business operations has been transformed by the digital revolution. From communication to data storage, the modes have shifted from tangible to virtual platforms. This transition has been a boon in many ways. However, the virtual world, much like its physical counterpart, is not devoid of threats.

Previously, threats were physically visible, like a fire, necessitating measures like fire drills. Today, threats are more intangible, often lurking behind an innocent-looking email or website link. This paradigm shift means that cyber safety has become as crucial as any other workplace safety protocol. It is here that cyber hygiene courses play a significant role.

Most employees, regardless of their designation or role, interface with digital tools like emails, messaging platforms, and digital databases. This widespread access to digital tools, while indispensable, poses a significant risk. If employees are not equipped with basic cyber hygiene knowledge, even unintentional actions can expose the entire organization to threats.

A deep dive into the essentials of cyber hygiene training

Every company has a diverse set of employees, from those in HR and marketing to IT professionals, legal experts, and database managers. While their roles vary, their interaction with the company's IT infrastructure is common, necessitating cyber hygiene training for all in the following categories:

Awareness of threats. The digital realm has a vast array of threats, from phishing attacks to malware and deceptive social engineering tactics. Comprehensive training ensures employees can identify these threats, mitigating potential risks.

Password protocols. A strong password can often be the first line of defense against cyber-attacks. Employees need guidance on creating robust passwords and the benefits of two-factor authentication.

Data protection. Data is often referred to as the 'new oil.' In a business context, data can include everything from company secrets to customer details. Understanding the importance of data and the protocols for its protection is paramount.

Incident management. Not every threat can be prevented. However, swift action can often limit the damage. Employees should be trained to recognize unusual activities and report them promptly.

The in-house vs. third-party training dilemma

Recognizing the need for training is only the beginning. The subsequent challenge is determining the optimal delivery method. The question arises: should businesses lean on their established in-house IT teams, or would it be wiser to seek the expertise of external professionals?

When considering the Advantages of Engaging External Specialists, several factors stand out:

Proficiency. Firms in the cybersecurity domain naturally offer a reservoir of specialized knowledge. Their immersion in the field ensures that they bring a high degree of expertise to the table.

Bespoke solutions. Each business has its nuances. Recognizing this, external specialists are adept at fashioning strategies that are uniquely tailored, focusing on a company's specific requirements and vulnerabilities tied to their industry.

State-of-the-art tools. Another compelling reason to consider them is their familiarity with the latest in the cybersecurity landscape. These experts have their fingers on the pulse, utilizing cutting-edge tools and being aware of evolving threat scenarios. This ensures training remains pertinent and forward-thinking.

Yet, it's essential to balance these benefits with potential drawbacks. Among the challenges of relying on external expertise are the costs involved, which can stretch the budget, especially for larger organizations. There's also the concern that an external perspective might miss nuances inherent to a company's internal processes and culture.

On the other hand, the Benefits of Internal Training are manifold:

Personalization. An internal approach offers a distinct advantage in its adaptability. Companies can sculpt the training, ensuring it's laser-focused on their infrastructure and unique challenges.

Autonomy. Having in-house training offers an unparalleled level of control. Every stage, from conception to delivery, remains under the company's purview.

The economic perspective. While the outset might require considerable investment, the long-term financial implications of in-house training can often skew towards being more economical.

Yet, as with all strategies, there are inherent challenges to consider. Relying solely on in-house capabilities can sometimes lead to gaps in expertise. Limited resources might also become a constraint, and the time commitment to design and implement robust training modules shouldn't be underestimated.

Ensuring periodic refreshers

Experts recommend holding awareness courses at least once a year to update employees' knowledge and skills. Whenever new technologies are introduced or new security threats emerge, separate training should be conducted. This is to ensure that knowledge is up-to-date and to avoid compromising the effectiveness of the company's defenses.

Employees who have already taken a full course do not need to retake the same course every year. Testing can be done to determine if the employee has lost knowledge, as well as new training on updates and new attack techniques. For those employees who have forgotten some of the topics and have difficulty with them, a shortened version of the training can be scheduled. Also, knowledge should be updated after a cyber incident and a case study should be conducted.

The bottom line

Cybersecurity today has become an important part of human security. While in the past it was more common to steal money in the underground or on the street, today it is increasingly being done online. Whereas in the past, attackers only had physical opportunities to harm a business, today any company can be attacked online.

Statistically, the most common cause of a cyberattack is human error. That's why employee cyber hygiene training is the foundation of all the basics in a company's information security. No matter how advanced anti-viruses are installed, no matter how professional the IS department is, one small mistake by an ordinary manager and the company's database is in the hands of attackers or a malicious program enters the company's network.

Regular sessions on cyber security not only prevent such incidents but can also help raise threat awareness and strengthen the security culture of an organization.

Augmented Reality (AR) has made a huge impact on various sectors, ranging from gaming and entertainment to healthcare and industrial applications.

Indeed, these elements collectively render banking apps a lucrative target for attackers. Therefore, it is imperative for financial institutions to fortify their mobile apps to safeguard user data and assets. Having understood the vulnerabilities, let's now explore the specific threats that mobile apps are exposed to.

Identifying common vulnerabilities in banking apps

Cybercriminals are perpetually scouting for weaknesses in these apps to exploit and gain unauthorized access to user accounts. Despite the security protocols in place to shield user data, here are some prevalent vulnerabilities that could undermine mobile banking security:

Inadequate data protection. Mobile banking apps sometimes store sensitive details like user credentials and transaction histories on the device itself. If not encrypted or securely stored, this data can be an easy target for attackers.

Interception attacks. Man-in-the-middle (MITM) attacks happen when a hacker intercepts the communication between the user's device and the app's server, allowing them to view and alter the transmitted data, including login details and financial transactions.

Weak authentication protocols. Insufficient authentication methods, such as basic passwords or lack of multi-factor authentication, can facilitate easy access to user accounts for attackers. Hence, robust lockout systems, along with multi-factor authentication, should be implemented to prevent brute-force attacks.

Service sharing. Mobile banking apps sometimes share services with other apps on a device, creating potential security risks if those apps are susceptible to attacks.

Flawed encryption techniques. Encryption is vital for safeguarding sensitive data. However, if a banking app employs weak or improperly implemented encryption algorithms, it can be easily bypassed by attackers. Code Manipulation Attackers might alter the app's code by adding or modifying malicious code, enabling them to access confidential data or seize control of the app.

Exploiting app vulnerabilities. Attackers might exploit vulnerabilities in the app itself, arising from insecure coding practices or outdated software components. A notable instance is the 2016 incident where hackers siphoned off $81 million from the Bangladesh Central Bank by exploiting a flaw in the SWIFT payment system utilized by the bank.

These vulnerabilities can severely compromise mobile banking security, potentially leading to financial losses and identity theft. Hence, it is vital for app developers to establish stringent security protocols.

How to fortify your mobile banking apps?

To guarantee the integrity of mobile banking apps, it is essential to adopt potent security strategies. In this segment, we will outline some of the most effective security protocols to shield against common app vulnerabilities:

Data encryption. Encrypting data is a potent security strategy that renders the data unintelligible to those without the decryption key, thereby thwarting attempts to misuse encrypted sensitive data.

Multi-factor authentication (MFA). MFA necessitates users to furnish multiple forms of verification before accessing their accounts, adding an additional security layer to mobile banking apps.

Application strengthening. Application strengthening involves altering the app's code to hinder reverse engineering attempts. This includes code obfuscation, data encryption, and incorporating anti-tampering mechanisms, making it challenging for attackers to retrieve sensitive data or alter the app.

Hence, utilizing platforms like GuardRails can facilitate easier vulnerability detection and rectification, streamlining the process for both security and development teams.

Conclusion

While mobile banking apps have transformed financial management, they have introduced significant security concerns. Given the growing reliance on mobile apps for banking transactions, safeguarding mobile banking security is paramount to prevent financial and reputational damage. It is incumbent upon both individuals and organizations to comprehend the risks and adopt necessary precautions against potential threats. Banks and financial institutions must establish robust security protocols to protect customer data and finances. We have highlighted some prevalent banking app vulnerabilities and potential mitigation strategies. Regular security assessments, staff training, and customer awareness are crucial to maintaining a resilient mobile banking security stance. By adopting these strategies, banks can substantially diminish the risk of cyber-attacks, safeguarding customer assets and data, and ensuring that the convenience of mobile banking does not compromise security.

In the interconnected world of the 21st century, social media platforms have seamlessly integrated into our daily lives. They have revolutionized the way we communicate, share information, and even conduct business. These platforms, while fostering global connections and instant communication, also present a double-edged sword, especially for corporate entities. The delicate balance between accessibility and security is a tightrope that many companies grapple with, often finding themselves at a crossroads.

The allure and perils of unrestricted access

The digital age has ushered in an era where information is at our fingertips. The modern employee, driven by a desire to stay connected and informed, often finds the allure of unrestricted access to social media hard to resist. While tools like anonymizers, VPNs, and TOR provide gateways to this vast world, they also inadvertently open Pandora's box of cyber threats. These backdoors, often overlooked, can be exploited by seasoned cybercriminals, leading to catastrophic data breaches, significant financial losses, and irreparable damage to reputations. This begs the question: at what cost does this unrestricted access come?

The digital footprint

Every click, post, like, share, or comment on social media platforms contributes to an extensive digital trail. This trail, visible to anyone with the right tools, can be a goldmine for cybercriminals. By meticulously combing through this data, malicious entities can construct detailed profiles, targeting not just individuals but entire corporate hierarchies. The weaponization of this information can manifest in various sinister ways, from spear-phishing campaigns targeting specific employees to broader, more devastating attacks on a company's digital infrastructure. The depth and breadth of this footprint often go unnoticed until it's too late.

Historical context: lessons from past breaches

History is replete with examples that underscore the vulnerabilities tied to social media. The 2013 breach of the Associated Press's Twitter account serves as a grim reminder. Hackers disseminated false information about a terrorist attack, causing widespread panic and a temporary stock market crash. Similarly, the 2011 attack on RSA, a renowned system developer, highlighted the dangers of seemingly innocuous phishing emails. These emails, sourced from data harvested from social media, contained malicious links that, once clicked, wreaked havoc on the company's systems. More recent incidents, like the one faced by Elara Caring in 2020, further emphasize the ever-present and evolving nature of these threats.

The multifaceted nature of social media threats

The digital realm is vast, and so is the spectrum of threats emanating from social media. Phishing attacks, where cybercriminals don the guise of trustworthy entities, are becoming increasingly sophisticated. Corporate espionage, where competitors or rogue actors siphon confidential information for financial or strategic advantage, adds another layer of complexity. Even actions that seem benign on the surface, like an employee sharing a casual photo from their workstation, can inadvertently disclose confidential information. The ripple effects of such breaches can be far-reaching, affecting not just the immediate organization but also its stakeholders.

Towards a comprehensive security strategy

In the face of such multifaceted threats, a piecemeal approach to security won't suffice. Companies need a comprehensive, holistic strategy. This involves regular employee training not only to equip employees with the tools to recognize potential threats, such as phishing emails but also to instill a culture of vigilance and best practices for online behavior. The nuances of password security, the importance of two-factor authentication, and the need for restricted access rights are foundational pillars that need to be emphasized.

However, human vigilance alone isn't enough. The rapid advancements in technology have armed companies with powerful tools like AI and machine learning. These technologies, capable of analyzing vast datasets swiftly, offer a proactive approach to security. They can detect anomalies, identify potential threats in their nascent stages, and even block malicious attempts, such as phishing emails before they reach their intended targets.

The collaboration further strengthens this security framework. In the vast expanse of the digital realm, no company stands alone. By forging strategic alliances with external partners, including cybersecurity firms and industry peers, companies can share insights, pool resources, and present a united front against cyber threats. This collaborative ethos ensures that knowledge and expertise are continuously exchanged, enhancing the collective security posture.

Lastly, adaptability is key. The digital threats of today might not be the same as those of tomorrow. A robust security strategy is dynamic, evolving in response to new challenges and threats. Feedback mechanisms, where employees can promptly report suspicious activities, coupled with regular audits and assessments, ensure that security measures remain agile and ahead of potential threats.

Conclusion

The intricate dance between social media and corporate security is a testament to the challenges and opportunities of the digital age. While the threats are formidable, a proactive, informed, and collaborative approach can keep them at bay. In this ever-evolving landscape, security is not just an IT concern; it's a collective responsibility. By fostering a culture of awareness, vigilance, and collaboration, corporations can navigate the digital realm confidently, reaping its benefits while ensuring their assets remain secure.

Within the spheres of information systems and software development, the role of test servers is undeniably essential. Test servers are purpose-built environments designed to experiment, examine new features, and test software updates without posing any threat to the stability and continuity of the main operational systems.

However, the nature and purpose of these test servers inherently introduce an array of information security risks. In this more extensive discussion, we will delve deeper into the central cybersecurity issues associated with the operation of test servers, and propose potential countermeasures and protective strategies.

Unpacking the core problem

A prevalent misconception among developers and IT professionals is that test servers represent an insignificant component within the larger company infrastructure. Consequently, they often exhibit a level of nonchalance towards these servers' security, believing that any attack, compromise, or system failure will not impact the primary infrastructure's operation.

Simultaneously, the Information Security (IS) departments within organizations often relegate test server security to a lower priority, given the servers' perceived secondary status compared to the primary, production-grade infrastructure, which typically enjoys robust technical and organizational protection measures.

However, despite this dismissive attitude, test servers frequently handle sensitive data during the testing and debugging process. This data can range from main infrastructure configuration elements to the personal data of clients or employees. The result is a precarious situation where developers are utilizing sensitive data in an environment with minimal control and oversight, and the IS department is without the necessary resources and technical wherewithal to guarantee the security of this process. Given this scenario, an incident becomes not a matter of if, but a matter of when it will occur.

Incidents of note involving test servers

Due to their generally weaker protection measures compared to the main infrastructure, test servers can become attractive targets for cyber attackers. Malevolent actors can exploit these servers as a backdoor into the main infrastructure or gain unauthorized access to sensitive company data. This risk is clearly exemplified in several high-profile incidents:

Uber, in 2016, was subjected to a significant security breach related to their test server. Intruders were successful in accessing Uber's GitHub repository that stored archived files of application code. As a direct consequence of this incident, the perpetrators were able to access sensitive data, including comprehensive user and driver details.

Facebook, in 2013, fell victim to a data breach caused by insecure configuration and setup of a test server. The attackers managed to access a test server loaded with various development and testing tools. As a result, the personal data of over 6 million users were compromised, showcasing the potential harm from such incidents.

British Airways, in 2018, suffered a security breach that impacted their test server. Attackers intercepted data, including the personal and financial information of over 380,000 customers, by injecting malicious code into the airline's test server.

These incidents not only underscore the fact that the issues surrounding test servers can affect a wide array of industries but also emphasize that a security breach does not always necessitate an external hacker or intruder.

Pressure points and their protective measures

Test servers are generally configured to favor the IT department's ease of use, thus inadvertently leading to conventional security issues such as weak passwords and a lack of access restrictions. While such configurations might provide comfort to developers, they pose serious implications for overall information security. Some common issues related to test server security are:

Data sensitivity. It's common for companies to overlook the necessity to disguise or mask data used for testing. Similarly, it's not unusual for passwords for the test infrastructure to remain unchanged for extended periods.

Protection levels. Regular servers typically have more robust protection measures such as firewalls, intrusion detection systems, and intrusion prevention systems. On the contrary, test servers, which are meant for simplified operation and testing, frequently lack these powerful security mechanisms. These servers usually belong to a separate network infrastructure that offers a lower level of protection.

Access control. In the case of test servers, all users commonly have the same high-level permissions, making the infrastructure susceptible to breaches due to weak or duplicated passwords.

Vulnerabilities and bugs. Test servers, being the platform for new features and updates, may often contain older software versions, potentially brimming with exploitable vulnerabilities.

To tackle these issues, one primary protection method is to never use sensitive data in its unprocessed form on test servers. Data masking, despite being resource-intensive, can significantly decrease the severity of a potential leak.

In addition, the importance of a well-structured regulatory framework cannot be overstated. Even with minimal resources, adhering to a set of clear, structured regulations can greatly enhance the security of the test infrastructure.

Final thoughts

Security measures for test servers form a vital part of the overall development and testing process. Although dealing with test servers carries inherent risks that can have severe consequences for the company and its users, implementing appropriate security measures can greatly minimize these risks.

Key steps towards secure test servers include the isolation of test servers on a separate network, deployment of robust authentication and authorization mechanisms, regular server updates and configurations, restrictions on access to test data, and frequent vulnerability checks.

Security should not be an afterthought, but rather an integral part of every phase of development and testing. By instilling strong security measures, adhering to industry best practices, and regularly updating your security policies in line with the latest information security trends, the risks associated with test servers can be substantially mitigated. This ensures that data confidentiality and integrity are preserved, protecting your company from potential threats and incidents associated with test servers.

When it comes to investing in company security, there are different approaches. Some organizations allocate substantial funds to proprietary solutions offered by vendors, while others opt to develop their own SIEM (Security, Information and Event Management systems) using open-source code.

The question arises: which option is more cost-effective in practice? Should one pay for a proprietary solution or rely on open-source alternatives? In this article, we delve into the realm of free SIEM solutions used in companies today, as well as the reasons why information security specialists often exhibit reluctance towards them.

A closer look at open-source SIEM systems

The appeal of open-source solutions increases with fewer restrictions. The most popular free SIEMs possess the ability to handle any number of users and data, offering scalability, and garnering support from the IT community.

Among the top-tier open-source SIEM systems, you’ll find:

AlienVault OSSIM SIEM. A version of AlienVault USM, a leading solution in this domain worldwide. Users gain access to a free framework encompassing intrusion detection systems, network and host monitoring, vulnerability scanning, and other open-source tools.

MozDef. Developed by Mozilla, MozDef is a SIEM system created from scratch. Similar to AlienVault OSSIM SIEM, it is built upon tried and tested open-source projects. The developers claim that MozDef can handle over 300 million events daily.

Wazuh. Originally developed within another open-source SIEM system called OSSEC, Wazuh evolved into a standalone product. It is capable of simultaneously collecting data through agents and system logs. Wazuh boasts a modern web interface, REST API, and an extensive set of rules.

OSSEC SIEM. Often referred to as the older sibling of Wazuh, OSSEC SIEM is widely recognized in the information security community as a reliable free intrusion detection solution.

Sagan. This SIEM tool specializes in real-time analysis of network inputs and the evaluation of their correlations. Its high performance stems from a multi-threaded architecture.

Prelude OSS. Serving as an open-source counterpart to the paid Prelude SIEM system from French developer CS, Prelude OSS supports various log formats and seamlessly integrates with popular open-source tools developed by others.

Additionally, companies often employ other free products like ELK SIEM, Snort, Suricata, SecurityOnion, Apache Metron, and more to construct their own systems. Many of these options are limited versions of proprietary software offered by vendors to familiarize users with their core systems.

When open source code is appropriate

One popular reason for implementing open-source SIEM today is to test-drive commercial systems, even with a minimal set of features. Free open-source versions allow professionals to evaluate expensive products in a live environment and gain insights into their inner workings.

Moreover, an open-source SIEM system becomes a viable choice when an organization can engage a large team of programmers. Any open-source solution necessitates further development and adaptation to fit seamlessly within the company's IT infrastructure. If there is no team available to handle these tasks, the utilization of free solutions loses its purpose.

One of the main challenges faced by companies employing open-source software is the lack of qualified specialists. Developing and maintaining such SIEM systems requires experienced Linux administrators, analysts, and experts proficient in connecting new sources, developing correlation rules, designing dashboards, and more. Given that freeware often comes with minimal features and customization options out of the box, significant work is involved, particularly during the initial months post-implementation.

These factors can impact the total cost of ownership of a system. Consequently, Open Source SIEM is a viable choice only for those who possess a thorough understanding of their requirements and have the necessary resources.

Challenges in open-source SIEM

There is a saying that "Linux is only free when you don't value your time." The same holds true for open-source SIEM tools. Difficulties in product improvement contribute to the compromised security of open-source products. Addressing identified vulnerabilities can often take weeks or even months, providing an opportunity for cybercriminals to exploit them.

There are other notable considerations when it comes to open-source SIEM. Specifically, an open-source system. For example, it lacks official technical support: User queries regarding installation and maintenance of free solutions are typically addressed by fellow users, rather than a dedicated owner-developer of the software. Moreover, it may simply cease to exist. Indeed, even if a community actively supported a product yesterday, it may be abandoned the next day, leaving users without crucial updates.
Next, it’s not a ready-to-use solution. To ensure proper functioning with data sources, connectors are required to convert incoming events into a compatible format for further processing.

These challenges are inherent to open-source SIEM systems and cannot be completely avoided. It is up to each company to determine whether they are willing to accept these risks.

Conclusion

Open Source SIEM systems are not universally suitable for every company. On one hand, adapting open-source code to align with specific requirements necessitates a team of highly skilled IT professionals and significant financial resources. On the other hand, regulatory requirements often dictate the installation of certified software in most cases.

However, dismissing open-source tools entirely would be unwise. They can be employed as references when establishing requirements and preferences for paid SIEM solutions.

This latest update demonstrates our focus on refining user experience and enhancing collaborative password management.

No longer will you need to create password copies in various vaults — we've introduced shortcuts. With these handy labels, you can easily organize access to passwords from different directories.

The new enhanced settings provide administrators with more control over configurations and user rights, and all changes require approvals, preventing any unintentional actions.

LDAP user management has now become simpler with its cleaner interface and background data updates.

In addition to that, Passwork 6.0 brings new notifications and interface improvements. All these enhancements contribute to a more comfortable user experience while ensuring the security of passwords and sensitive data.

Shortcuts

Shortcuts are a new way to share passwords, enhancing collaboration flexibility. There's no need for creating password duplicates in different vaults — instead, create multiple shortcuts in required directories. All changes to original passwords are reflected in shortcuts, keeping your team up to date. Users can view or edit data via shortcuts according to their access rights.

Sending passwords without granting partial access to vaults

Previous versions of Passwork encrypt passwords at the vault level. This type of encryption gives users partial access to vaults even when a single password is shared with them. Now, when users access passwords via their "Inbox" or a shortcut, they receive keys to specific passwords, but not their vaults.

Administrators can clearly see who has vault access rights, and who can only work with specific passwords.

LDAP

The LDAP interface is now cleaner and more intuitive, with a reimagined user management logic. Adding new LDAP users is simpler and safer, especially with the client-side encryption enabled.

Previously, admins had to add an employee and provide a master password. Now, users set their master passwords upon the first login, and admins confirm them afterwards.

The "Users" tab shows registered users, and there is a separate window for adding new ones. LDAP user data updates take place in the background, allowing admins to navigate elsewhere without waiting for data refresh.

Passwork now provides more detailed security group information. The groups that are linked to roles are marked with special tags, and the groups which were not loaded from LDAP during the last update are marked as "Deleted", alerting admins to adjust the search settings or remove such groups. Also, you can now see the members of each security group.

Improved settings

We've redesigned all settings sections for a unified visual style and enhanced functionality, reimagined the logics of some settings.

Rights for links, tags, and password sharing. Previously, these settings were applied individually to each user. Now, they are applied to everyone with a certain level of vault access. For example, anyone with the “Edit” access rights or higher can create hyperlinks to passwords. These parameters are located in the system settings under the “Global” tab.

Change confirmation. We've added “Save” and “Cancel changes” buttons in system settings. Now, any changes to settings must be confirmed — this helps to prevent accidental actions.

Custom auto-logout time. Users can now set these parameters individually, and admins specify the maximum inactivity time period before automatic logout.

Language selection. In the new version of Passwork, admins can allow employees to choose their interface language.

Interface enhancements

Improved drag and drop. Now, when dragging and dropping passwords and folders into desired directories, Passwork displays selectable actions — move, copy, or create a shortcut.

Other improvements

Separate windows for access to the safe and additional access. Vault access info is now split into two easy-to-read windows. One window shows users who has access to a specific vault, and the other displays alternative ways passwords from this vault can be accessed — shortcuts, hyperlinks, or shared passwords.

Redesigned password action buttons. On the password panel, we've added the "Edit" button and grouped together all actions for additional password access via shortcuts, links, or direct user sharing.

Additional fields for password import and export. Passwork 6.0 supports the use of custom fields, that means you can transfer not only login and password but also additional information stored within password cards.

New notifications. Administrators will receive notifications about new unconfirmed users, and employees will be notified of new passwords in the "Incoming" section.

Symmetric algorithms, forming the backbone of modern cryptography, offer a secure method of encrypting and decrypting data utilizing a single shared key. They have been widely adopted for their unmatched speed and efficiency. Like any other technology, symmetric algorithms come with their own set of benefits and drawbacks. This article seeks to offer a comprehensive review of the pros and cons of symmetric algorithms, providing a deeper understanding of their integral role in data security and the potential challenges they entail.

Pros of symmetric algorithms

Unrivaled efficiency

Symmetric algorithms are best known for their superior efficiency in handling large volumes of data for encryption and decryption. The use of a single key significantly reduces the demand for computational resources, setting symmetric algorithms apart from their asymmetric counterparts. This makes them an excellent fit for applications that demand high-speed data processing, including secure communication channels and real-time data transfers.

Impressive speed

Symmetric algorithms, by virtue of their simplicity, can process data at a much faster rate than asymmetric algorithms. Without the need for complex mathematical operations, such as prime factorization or modular arithmetic, symmetric algorithms can encrypt and decrypt data rapidly, reducing latency. This speed advantage is particularly beneficial for applications requiring swift data encryption, including secure cloud storage and virtual private networks (VPNs).

Key distribution

Symmetric algorithms simplify the key distribution process. Given that both the sender and receiver utilize the same key, they only need to execute a secure key exchange once. This offers increased convenience in scenarios where multiple parties need to communicate securely, such as within large organizations, military operations, or corporate communications.

Computational simplicity

Symmetric algorithms are relatively straightforward to implement due to their computational simplicity. This allows for efficient coding, making them ideally suited for resource-constrained devices that possess limited computational capabilities, such as embedded systems or Internet of Things (IoT) devices. This simplicity also contributes to easier maintenance and debugging, reducing the potential for implementation errors that could compromise security.

Cons of symmetric algorithms

Complex key management

The management and distribution of shared keys are significant challenges inherent to symmetric algorithms. The security of these algorithms is closely tied to the confidentiality of the key. Any unauthorized access or compromise of the key can lead to a total breach of data security. Consequently, robust key management protocols are essential, including secure storage, key rotation, and secure key exchange mechanisms, to mitigate this risk.

Lack of authentication

Symmetric algorithms do not inherently provide authentication mechanisms. The absence of additional measures, such as digital signatures or message authentication codes, can make it challenging to verify the integrity and authenticity of the encrypted data. This opens the door for potential data tampering or unauthorized modifications, posing a considerable security risk.

Scalability

Symmetric algorithms face challenges when it comes to scalability. Since each pair of communicating entities requires a unique shared key, the number of required keys increases exponentially with the number of participants. This can be impractical for large-scale networks or systems that involve numerous users, as managing a vast number of keys becomes complex and resource-intensive.

Lack of perfect forward secrecy

Symmetric algorithms lack perfect forward secrecy, meaning that if the shared key is compromised, all previous and future communications encrypted with that key become vulnerable. This limitation makes symmetric algorithms less suitable for scenarios where long-term confidentiality of data is crucial, such as secure messaging applications.

An in-depth analysis of symmetric algorithms

Symmetric algorithms, including the widely adopted AES, DES, and Blowfish, are favored for their speed and efficiency. However, their robustness is largely dependent on the size of the key and the security of the key during transmission and storage. While larger keys can enhance security, they also increase the computational load. Thus, selecting the appropriate key size is a critical decision that requires a careful balance between security and performance requirements.

One of the standout strengths of symmetric encryption is its application in bulk data encryption. Because of their speed, symmetric algorithms are ideally suited for scenarios where large amounts of data need to be encrypted quickly. However, they may not always be the best solution. In many cases, asymmetric encryption algorithms, despite their higher computational demands, are preferred because of their additional security benefits.

It's also crucial to note that cryptographic needs often go beyond just encryption and decryption. Other security aspects, such as data integrity, authentication, and non-repudiation, are not inherently provided by symmetric algorithms. Therefore, a comprehensive security scheme often uses symmetric algorithms in conjunction with other cryptographic mechanisms, such as hash functions and digital signatures, to provide a full suite of security services.

Final thoughts

Symmetric algorithms occupy a pivotal place in the realm of cryptography. Their efficiency and speed make them an invaluable asset for many applications, especially those involving large-scale data encryption. However, the limitations inherent in symmetric algorithms, including key management complexities, lack of authentication, and absence of perfect forward secrecy, necessitate meticulous implementation and the incorporation of additional security measures.

The marvels of modern computing are, in part, thanks to advances in artificial intelligence. Specific breakthroughs in large language models, such as OpenAI's GPT-4 and Google's BERT, have transformed our understanding of data processing and manipulation. These sophisticated models masterfully convert input data—whether it be text, numbers, or more—into a form that machines can understand. This intricate process, known as data encoding, serves as the foundation for these models to comprehend and generate human-like text. Let's delve deeper into the intricacies of data encoding and how it powers the magic of AI language models.

The secret code of machines

The beginning of the journey involves comprehending how GPT-4 or BERT processes sentences typed into them. Contrary to human processing capabilities, these models can't directly interpret words. Instead, they employ something known as word embeddings. This complex yet efficient technique transforms each word into a unique mathematical form—akin to a secret code decipherable only by machines. Each encoding is meticulously performed to ensure that semantically similar words receive comparable codes. The aim is to create a rich, multidimensional landscape where each word's meaning is determined by its location relative to other words.

The role of positional encoding in context understanding

While individual words carry their importance, the structure of language extends beyond isolated entities. The sequence of words, the context, can drastically alter the meaning of a sentence. To illustrate, consider the phrases "Dog bites man" and "Man bites dog." The same words are used, but their arrangement creates entirely different narratives. That's where positional encoding enters the picture. By assigning each word an additional code indicating its position in the sentence, positional encoding provides models with a vital understanding of language structure and syntax.

The attention process: making words context-aware

After word and positional encoding, these mathematical representations, or word embeddings, undergo an 'attention' mechanism. Here, each word embarks on a figurative group discussion with all the other words in the sentence. During this interaction, each word decides the importance it should attribute to the others. For instance, in the sentence "Jane, who just moved here, loves the city," the word "Jane" would assign significant attention to "loves."

These 'attention' weights are then used to compute a new representation for each word that is acutely aware of its context within the sentence. This batch of context-aware embeddings journeys through multiple layers within the model, each designed to refine the model's understanding of the sentence. This systematic processing prepares the model to generate responses or predictions that accurately reflect the intended meaning of the sentence.

GPT-4: writing text one word at a time

GPT-4 has adopted a unique approach when it comes to generating text. It operates on a "one word at a time" principle. Beginning with an input, it predicts the next word based on the preceding context. This predicted word is then included in the context for predicting the following word, and the process repeats. This strategy allows GPT-4 to produce text that is not just grammatically coherent, but also semantically relevant, mirroring the way humans write one sentence after another.

BERT: a 360-degree view of sentence context

BERT, on the other hand, possesses a distinct capability that sets it apart from other models. It can process and understand text in both directions simultaneously. BERT does not limit itself to considering words before or after a given word. Instead, it absorbs the entire context at once, effectively offering a 360-degree view of the sentence. This bidirectional understanding enables BERT to comprehend the meaning of words based on their complete context, significantly enhancing the model's ability to interpret and generate nuanced responses.

The versatility of data encoding

While language forms a significant chunk of these models' use cases, they aren't confined to it. An exciting feature of models like GPT-4 and BERT is their ability to work with any kind of sequential data. This characteristic opens up a universe of possibilities for diverse fields, from composing harmonic music to decoding complex genetic sequences, predicting stock market trends, or even simulating game strategies. By analyzing patterns in the sequential data, these models can unearth hidden insights and produce creative outcomes, making them an invaluable asset in numerous areas beyond language processing.

Expanding horizons: applications and future prospects

The wonders of data encoding do not stop with text generation. In fact, the potential applications of these AI models are continually expanding. They can be used to aid human decision-making in complex scenarios, such as medical diagnosis or legal analysis, by digesting massive amounts of textual data and making informed suggestions. In the field of research, they can help summarize lengthy academic papers or generate new hypotheses based on existing literature. The entertainment industry isn't left out either, as these models can create engaging content, ranging from writing captivating stories to generating dialogues for video games.

Moreover, GPT-4 and BERT's remarkable abilities to understand and manipulate language are catalyzing research into other AI models. Researchers are exploring ways to combine the strengths of various models and reduce their limitations, which promises an even more exciting future for AI.

Conclusion

In conclusion, data encoding in AI models like GPT-4 and BERT can be likened to watching a symphony of processes working in perfect harmony. From word embeddings and positional encoding to attention mechanisms, these models leverage a series of intricate techniques to decode the hidden patterns in data, transforming it into meaningful information. The incredible capability of these models to understand context, generate human-like text, and adapt to diverse data types is revolutionizing the field of artificial intelligence, paving the way for a future brimming with AI innovations.

The intricate dance between spies and encryption has been played out over thousands of years, and its rhythm continues to quicken. As we delve deeper into this dance, we see a confluence of technology, secrecy, and intelligence that has shaped the course of history and continues to impact our world today.

A brief history of encryption

Encryption, in its essence, is about transforming information into a code that is unreadable to anyone except the intended recipient. The Ancient Greeks and Romans were among the first to understand this concept. They used simple substitution ciphers, where each letter in a message would be replaced by another letter. The Caesar Cipher, used by Julius Caesar for secure military communications, is a classic example. This cipher was a simple shift of the alphabet, and while it was easy to break, it underscored the vital principle of encryption: the ability to shield information from prying eyes.

Fast forward to the World Wars, and we see the stakes rising. Encryption technology became more advanced and intertwined with the art of espionage. The Enigma machine, utilized by the Germans during World War II, is a well-known example of this progression. The Enigma was an electromechanical device that used a set of rotating disks to scramble plaintext messages into complex ciphertext. The machine's complexity made it a powerful tool for clandestine communication, and cracking its code was a task that required immense intellectual prowess.

The British cryptanalysts at Bletchley Park, led by Alan Turing, took on this monumental challenge. Their efforts to break the Enigma code were not just a victory for cryptography but also a critical factor that contributed to the Allied victory. It was espionage and counter-espionage at its finest, with encryption at the heart of the battle.

The Cold War saw the battleground shift, but the importance of encryption remained the same.

Cryptic case studies

In the last few years, we've seen several noteworthy instances where spies have used encryption and other covert tactics to achieve their goals. Let's explore five recent cases:

1. Walter Glenn Primrose and Gwynn Darle Morrison were apprehended for a most unusual crime: the theft of deceased infants' identities. The case took a peculiar twist when a photograph was discovered featuring the duo dressed in what was purportedly KGB uniforms. The objective behind this odd photograph remains shrouded in ambiguity. However, this case casts a spotlight on the extraordinary lengths to which spies will resort to obfuscate their true selves, potentially utilizing encryption as a tool to further conceal their covert activities.
   
2. In another instance, the veneer of Russian intelligence's machinations to sway U.S. elections was peeled back with the indictment of Alexandr Viktorovich Ionov. This indictment served as a window into the operational mechanics of the Russian FSB, divulging their deployment of an array of stratagems, including the use of encryption and disinformation campaigns, to sow seeds of chaos within the United States and undermine the foundations of global democracy.
   
3. A narrative involving U.S. nuclear engineer Jonathan Toebbe and his spouse, Diana, unfolded as the pair tried to profit from selling purloined U.S. Navy nuclear documents and designs in exchange for cryptocurrency. Their surreptitious operation was derailed by an FBI sting operation, underscoring the pivotal role of counterintelligence mechanisms and encryption in the intricate world of modern espionage.
   
4. In 2022, European nations initiated a large-scale crackdown on Russian intelligence operations that resulted in the expulsion of 556 Russian intelligence officers and diplomats. This widespread ejection served to hinder Russia's influence operations on European soil and stifle their capacity to manage and support their spy networks. This incident underscores the concerted global efforts being taken to neutralize encrypted espionage activities.
   
5. China remains a prominent figure on the stage of global espionage, relentlessly targeting Western technological knowledge and silencing dissent within the Chinese diaspora. One particularly significant case involved Yanjun Xu, an intelligence officer who set his sights on the U.S. aerospace sector. Xu's subsequent 20-year prison sentence serves as a sobering testament to China's long-haul espionage strategy, the role of encryption in facilitating covert operations, and the international cooperative efforts required to counteract such threats.

Reflecting upon both historical and contemporary instances, one can see the intricate duality that encryption presents in espionage. As a tool, it simultaneously serves as a means for covert agents to veil their communications, maintaining the secrecy that their roles require. Simultaneously, it is the shield that protects sensitive data from falling into the wrong hands, acting as a safeguard against the very spies who would employ it for their own purposes.

As technology surges forward, the tactics and techniques of spies and cryptographers mirror this progression. This perpetual cycle of action and counteraction — the relentless pursuit to devise impenetrable codes on one hand, and the counter-effort to decode them on the other — encapsulates the ongoing relationship between espionage and encryption. This dance, marked by strategic maneuvering, continuous adaptation, and intellectual rigor, escalates in intensity with each passing moment, as each side ceaselessly strives to outsmart the other.

Summing up

In conclusion, the interplay between espionage and encryption is a nuanced ballet of complexity and evolution. Encryption serves dual roles in this dance: as a tool that facilitates the clandestine operations of spies, and as a defense mechanism against such covert activities. As we continue to ride the wave of technological advancement, the ties between espionage and encryption will undoubtedly become more intricate, more convoluted, and more pivotal. Whether the scenario involves state-sponsored cyber-espionage aiming to disrupt nations or individuals attempting to monetize state secrets, encryption remains a critical element in these engagements, forming the core of this ongoing battle.

Prioritizing data security is crucial for establishing trust, preserving patient privacy, and upholding the highest standards of healthcare.

Wearable technology has become increasingly popular in recent years, with devices like the Apple Watch, Fitbit, and Xiaomi gaining significant market share. These devices offer a wide range of features, from tracking fitness goals to monitoring health data and staying connected with the digital world. However, with the rise of wearable tech, concerns have been raised about how secure these devices are and whether they put user data at risk.

Challenges

The types of data that wearable tech collects vary from device to device. Some devices, such as fitness trackers, collect basic health data such as heart rate and activity level. Other devices, such as smartwatches, can collect more sensitive data such as location, messages, and emails. This data is typically stored on the device and synced to the cloud, making it accessible from any device that the user is logged into.

One of the most significant concerns with wearable tech is the security of this data. If the device or cloud storage is not properly secured, the data could be accessed by hackers who could use it for malicious purposes. For example, hackers could use location data to track users' movements or steal their identity by accessing their personal information.

To protect user data, most wearable tech companies implement security measures. For example, the Apple Watch uses encryption to protect data stored on the device, and it requires a passcode or biometric authentication to access the device. Similarly, Fitbit and Xiaomi use encryption to protect user data and offer security features such as two-factor authentication.

Despite these measures, data breaches in wearable tech have unfortunately become more common in recent years, highlighting the need for continued vigilance when it comes to security measures. For example, in 2017, researchers discovered a vulnerability in the Bluetooth communication protocol used by many wearable devices. This vulnerability, known as BlueBorne, allowed hackers to take control of devices and steal sensitive data.

In 2019, it was discovered that several popular fitness apps had inadvertently exposed sensitive user data. The apps, which were used in conjunction with wearable fitness trackers, had failed to properly secure user data, leaving information like usernames, passwords, and exercise routines vulnerable to attack.

Another example of a wearable tech data breach occurred in 2018 when hackers stole sensitive data from the Polar fitness app. The data, which included location data, was collected by the app's users and stored on Polar's servers. However, the servers were not properly secured, allowing hackers to access the data and track the movements of military personnel and intelligence agents in sensitive locations.

How to protect your data and privacy?

To protect your data and privacy when using wearable tech, there are several steps you can take. Firstly, always use strong, unique passwords for your wearable tech accounts, and consider using a password manager to help generate and manage these passwords.

By following the best practices outlined above, individuals and companies can minimize the risks associated with using wearable tech devices and enjoy the many benefits that these innovative devices offer.

Digital Rights Management (DRM) is a technology that is used to control the use and distribution of digital content, including music, movies, e-books, and software. The primary purpose of DRM is to ensure that digital content is only used in ways that are authorized by the copyright owner. DRM technology works by placing restrictions on the use of digital content, which are then enforced through encryption, digital signatures, or other methods.

DRM systems typically involve the use of software that is integrated with the content. This software is designed to control how the content is used and to prevent unauthorized access to the content. DRM systems can also be integrated with hardware devices, such as DVD players or e-book readers, to ensure that the content is only used in authorized ways.

One of the most common methods of implementing DRM is through the use of encryption. When digital content is encrypted, it is transformed into a code that cannot be understood without a key. The key is typically stored on a server, and it is used to decrypt the content as and when it is needed. DRM systems can also use digital signatures to authenticate the content and to ensure that it has not been tampered with.

DRM systems are designed to be flexible so that they can be customized to meet the needs of different types of digital content and different types of users. For example, a DRM system for music may allow users to play the music on a limited number of devices, while a DRM system for software may allow users to install the software on a single device.

DRM technology is utilized to protect a wide range of digital content, including entertainment media such as books, music, and videos, as well as sensitive business data, database subscriptions, and software programs. DRM helps content creators and copyright holders control how their work is used and prevent unauthorized changes or misuse.

Here are some examples of DRM in action:

iTunes. Apple's iTunes store uses DRM to limit the number of devices customers can use to listen to songs. The audio files purchased from iTunes contain information about the purchase and usage of the songs, which prevents access from unauthorized devices. Additionally, the content in the iBooks store is protected by FairPlay technology, which ensures that books can only be read on iOS devices.

Digital Music. Spotify uses blockchain technology and DRM to identify songs played and pay the right artist through cryptocurrency. The music streaming company acquired Mediachain to assist in this process.

Microsoft Software. before downloading Microsoft software, such as Windows or Office, users must accept the company's user license and enter a key. Microsoft also uses a kind of DRM technology called PlayReady to secure the distribution of content over a network and prevent unauthorized use of its software.

Sensitive Documents. Many organizations use DRM to protect business-critical documents and sensitive information, such as confidential employee data, business plans, and contracts. DRM allows organizations to track who has viewed files, control access, and manage usage, as well as prevent alteration, duplication, saving, or printing.

Regulatory Compliance. DRM is important for organizations to comply with data protection regulations, such as HIPAA for healthcare organizations and CCPA and GDPR for all organizations.

Despite the benefits of DRM, there are also some criticisms of the technology. Some users argue that DRM restricts their ability to use digital content in ways that they feel are reasonable and legitimate. For example, they may feel that they should be able to transfer a purchased song from one device to another or to make a backup copy of a digital book.

Additionally, DRM systems can be vulnerable to hacking and other forms of attack. If a DRM system is compromised, it can allow unauthorized access to the content, which can undermine the purpose of the DRM system. This has led some users to view DRM as an unnecessary restriction on their ability to use digital content and as a threat to their privacy and security.

Another criticism of DRM is that it can make it difficult for users to access their digital content in the future. For example, if a user switches from one device to another, they may find that their DRM-protected content is not compatible with their new device. Additionally, if the company that provides the DRM system goes out of business or discontinues support for the system, users may be unable to access their content.

Despite these criticisms, DRM remains an important tool for protecting the rights of copyright owners and for ensuring that digital content is used in authorized ways. DRM systems have been used by a wide range of companies, including music labels, movie studios, and software publishers, to control the use and distribution of their digital content.

In recent years, some companies have started to move away from DRM, recognizing that it can be a barrier to the adoption of digital content. For example, some music labels have started to offer DRM-free music downloads, recognizing that users are more likely to purchase music if they are not restricted in their ability to use it. Additionally, some e-book publishers have started to offer DRM-free books, recognizing that users may be more likely to purchase books if they are not restricted in their ability to use them.

However, despite these trends, DRM remains an important tool for many companies, especially for those that want to ensure that their digital content is used in authorized ways. DRM is particularly important for companies that are concerned about piracy, as it can help to prevent unauthorized copying and distribution of their content.

In conclusion, DRM is a technology that is used to control the use and distribution of digital content. DRM systems work by placing restrictions on the use of digital content and enforcing these restrictions through encryption, digital signatures, or other methods.

While DRM has its benefits, including the protection of the rights of copyright owners, it also has its criticisms, including restrictions on the use of digital content and the potential for hacking and other forms of attack. Nevertheless, despite these criticisms, DRM remains an important tool for many companies and is likely to continue to be used in the future.

The importance of protecting the safety and security of our digital devices and the data stored on them has grown significantly as technology continues to advance and become more integrated into our everyday lives.

Ransomware

A type of malware that encrypts a victim's files and demands a ransom in exchange for a decryption key.

Phishing attacks

Fraudulent attempts to obtain sensitive information, such as login credentials or financial data, by masquerading as a trustworthy entity.

Zero-day exploits

Attacks that take advantage of previously unknown vulnerabilities in software or hardware, giving developers no time to create and distribute patches.

Advanced persistent threats (APTs)

Long-term, targeted cyberattacks that often involve multiple attack vectors and are typically aimed at high-value targets, such as governments and large corporations.

Because cybercriminals are using more sophisticated strategies, it is essential for antivirus software and other cybersecurity solutions to evolve at the same rate in order to maintain their efficacy.

The limitations of traditional antivirus software

Traditional antivirus software primarily relies on signature-based detection, a method that compares files and programs against a database of known malware signatures. This strategy may be useful against recognized dangers, but it suffers from a number of limitations, including the:

Inability to detect new or unknown malware

Signature-based detection struggles to identify new malware variants or previously unknown threats, leaving users vulnerable to emerging cyber risks.

Slow response to new threats

Updating signature databases to include new malware often takes time, resulting in a window of vulnerability.

False positives and negatives

Signature-based detection can produce false positives (identifying benign files as malware) and false negatives (failing to detect actual malware), affecting the overall accuracy and effectiveness of the antivirus software.

The emergence of next-generation antivirus (NGAV) solutions

To address the limitations of traditional antivirus software and better combat the evolving threat landscape, the cybersecurity industry has developed next-generation antivirus solutions. NGAV products employ a combination of advanced techniques, such as:

The vast majority of individuals look for nearby WiFi hotspots on their laptop computers. The most up-to-date personal computers have the ability to instantly recognize whether a wireless connection is present. But what if you don’t want to go through the effort of unpacking your laptop, starting it up, logging on, and then strolling about with it just to discover that there is no wireless network coverage in the area where you are? Because of this, having a WiFi sniffer on hand may be quite helpful in assisting you in rapidly locating the nearest WiFi network.

What is a WiFi sniffer?

A WiFi sniffer is a portable instrument that can locate the wifi network that is closest to the user. In addition to this, it will assist you in determining the strength of the WiFi signal, and if there are many signals, a WiFi sniffer will prioritize the signals in terms of their strength, which will save the user both time and annoyance.

WiFi sniffers are available in a variety of device formats, either as a stand-alone appliance or as software add-ons that interact with your wireless mobile device. You may get a WiFi sniffer in any of these two ways. The add-ons may often be obtained through the service provider of your mobile device, although standalone WiFi sniffers can be purchased at any store specializing in the sale of computers or electronic goods.

WiFi sniffers are able to handle all kinds of wireless network cards and come included with a Prism2 driver that may assist you in determining the intensity of the signal. WiFi sniffers are developed using C++ programming and operate using an "n-tier" structure. The gathering of data begins at the lowest tier and progresses up to the topmost layer, which is where the user interface is placed.

How does a WiFi sniffer work?

The operation of a WiFi sniffer does not call for a significant amount of technical expertise and may be carried out with relative ease. If you are using the standalone device, which is compact and portable, all you need to do is push and hold down the main button, aim it in any direction where you wish to locate a wireless network, and then use the gadget. This will activate the gadget, and while it is looking for a signal, the device will display lights that revolve in a circular pattern. The indicator light will remain constant after it finds a wireless signal. This means that it has detected a wireless network that is within a range of 300 feet of your device.

In the event that a signal cannot be found, the rotating lights will continue to do so, and it may be required to attempt to look in a different direction. If you are in an area where the wireless signal is poor, it is possible that it may be necessary to make adjustments to the antenna. WiFi sniffers that are add-ons to your mobile device do their functions in a manner that is analogous to that of the standalone device. Nonetheless, their specific capabilities change depending on the sort of mobile device that you are utilizing.

WiFi sniffer features

Just like there are many various brands of wireless devices available on the market, there are also many different brands of WiFi sniffers, each of which has functions that vary depending on the model of the device. While searching for a high-quality WiFi sniffer, one of the qualities you should look for is a device that is capable of avoiding interference from other electronic gadgets and appliances, such as mobile phones, Bluetooth devices, and microwave ovens. The better-grade devices will have the ability to capture a wireless signal regardless of the environment that they are placed in.

The most effective kind of WiFi sniffer often operates on the 2.4GHz frequency band and has the capacity to identify WiFi signals for both 802.11b and 802.11b/g. It needs to be easy to carry around with you, be convenient, and be small enough to fit in your pocket or laptop bag.

WiFi sniffers that have the qualities described above are also useful tools for usage in the house. Whether you are setting up a home office or Internet-ready gadgets, a WiFi sniffer can assist you in determining the areas of your home with the strongest wireless signal so that you can optimize the signal's capabilities and get the most out of your home office or devices.

Isn’t a WiFi sniffer illegal?

No. Stumbling across a wireless network by using a WiFi sniffer is a much simpler process than wireless sniffing, as the two terms refer to quite distinct activities. A WiFi sniffer's sole purpose is to discover the location of the nearest accessible wireless connection; however, it cannot actually join the network itself. Eavesdropping on conversations taking place inside of wireless networks is what's known as wireless sniffing, and it's a technique that's intended to break into a network. The former is permitted but the latter is not, particularly when it is utilized in the commission of illegal conduct.

On the other hand, wireless sniffing is entirely within the law when it is employed by IT employees to monitor network incursions on a business or government infrastructure. This is the case whether the infrastructure is owned by a private company or the government. Monitoring the information packets that are sent over a network is what's referred to as "intrusion detection," and it's used to protect sensitive data from being stolen by hackers and other malicious users of the internet.

There are a few businesses that have made it illegal for customers to use WiFi sniffers, which are devices that randomly search for available wifi networks. Instead, corporations are deploying apps that are based on directories and that can be allowed for usage by mobile employees as well as other people.

Hopefully, the material presented here will assist you in gaining a deeper comprehension of WiFi sniffers and the functions they perform. In short, they’ll help you save time and stress while maximizing the signal strength of your home wireless network.

The majority of individuals don’t put much thought into the kind of web browser that they use. Typically, laptops or smartphones are equipped with a default browser like Microsoft Edge or Safari, leading people to assume it's the finest or sole choice available. Nevertheless, there are several other browser options to select from.

Your web browser is the medium through which you communicate with the majority of the internet, resulting in a substantial amount of personal information being managed by it. It is essential to ensure that you are using a secure browser since this data is highly valuable.

So, how much is your data worth? To marketing firms — quite a bit. Companies can sell your browsing data to third parties for profit, and that's just the start of it. Hackers are always on the lookout for people who are not using a secure browser, and exposing personal data in this manner can be incredibly risky.

Your browser and its ability to protect your privacy and security are critical. As a result, let's go through the top five secure browsers for 2023.

Firefox

In 2023, Firefox is considered one of the best web browsers as it is secure, open-source, and offers numerous customization options. Its high level of customization makes it an excellent choice for advanced users, yet it is also user-friendly, making it a great option for non-tech-savvy users.

Firefox blocks third-party tracking cookies automatically, resulting in faster browsing speeds than other browsers that allow websites to track user activity, like Chrome. It also features various security measures, such as anti-phishing and malware protection, minimal data collection, automatic tracker blocking, and encrypted browsing with DNS over HTTPS (DoH). It is also compatible with third-party security extensions.

Firefox's anti-phishing protections are impressive, as it is highly effective in detecting risky and known phishing sites when tested against a database of such sites. Additionally, Firefox's DoH protections encrypt search queries with CloudFlare or NextDNS's encrypted DNS servers, making it challenging for third parties to steal browsing history.

Although many highly secure browsers compromise convenience for protection, Firefox is simple to use and provides advanced security features. Users can adjust security settings, anti-tracker settings, and anti-phishing protections according to their preferences. Firefox is compatible with Windows, macOS, Android, and iOS.

Tor Browser

In terms of user privacy, Tor Browser is the top choice; however, it is not as fast as most of its competitors.

The name "Tor" is derived from "The Onion Routing," a technology that hides the user's IP address by encrypting web traffic and routing it through multiple servers. As a result, before a user's computer can access a website, their traffic must first pass through Tor's secure server network. Tor has been shown to conceal user activity from ISPs, hackers, trackers, and even governments. The NSA was reportedly unable to hack into the Tor network, as stated in Edward Snowden's leaked documents. Tor Browser is banned in certain countries that censor the internet because it provides users with unrestricted access to the web.

Tor's data collection policy is minimally intrusive, as it only collects usage data to assess browser performance. Despite being an advanced browser, Tor Browser's interface is user-friendly, and it uses the same source code as Firefox, with minor variations. Users can even install most Firefox extensions into Tor Browser. However, browser extensions increase the likelihood of machine identification by network surveillance tools, so users who wish to remain as private as possible should avoid using them.

While Tor Browser is highly secure, its onion routing technology will slow down the internet connection, similar to the effect of using a VPN. When users' traffic bounces off multiple servers, their connection speed is adversely affected. Nonetheless, Tor may be the ideal choice for users with a reliable internet connection who is willing to trade some speed for high security. Tor Browser is compatible with Windows, Android, macOS, and Linux.

Brave

Brave is a web browser that offers a fast browsing experience and comes with built-in ad and tracker-blocking features. With its "Shields" feature, Brave can automatically block ads and trackers, which allows it to load websites much faster than other browsers. This feature also provides an added layer of protection by blocking malicious web scripts that may try to infiltrate your device. In addition, Brave automatically sets up HTTPS connections, which use a secure encryption protocol to protect user traffic.

One of Brave's standout features is its ability to use Tor technology in Private Browsing mode, which encrypts your traffic through the Tor network. This ensures that your browsing activity remains hidden not only from other users on your device but also from your ISP and other network spies.

Brave also has a unique ad-buying program called Brave Rewards, which allows users to earn BAT (a type of cryptocurrency) by viewing or clicking on sponsored ads. These BATs can then be transferred to the sites and content creators of your choice. This program offers a great revenue solution for content creators as Brave ads generate revenue without using trackers, selling user data, or pop-ups that interrupt the browsing experience. Brave is available for Windows, Android, iOS, macOS, and Linux.

Google Chrome

The reason why Google Chrome is the most popular browser in the world is that it is compatible with all major platforms and provides users with an excellent interface as well as thousands of useful extensions. Google, with its large number of staff and resources, constantly updates and patches Chrome more quickly than any other browser developer to patch network vulnerabilities, man-in-the-middle attacks, browser glitches, and exploitable security holes.

Chrome's Safe Browsing feature uses Google's extensive database of unsafe sites to flag suspicious web pages, which is updated daily and detects more phishing sites than most other browsers. Additionally, Chrome uses sandboxing to prevent malicious web scripts and invasive trackers from stealing data or hacking devices. Users can choose DNS over HTTPS (DoH) protection in Chrome's settings for added privacy and protection from ISPs, governments, and network-snooping hackers, which is turned on by default in Firefox but only requires a single click in Chrome.

It's important to mention that Chrome's tracker blocking is limited due to Google's reliance on web trackers to gather user data for advertisers. Chrome collects user data by default, and while much of this data is used to enhance Chrome's security, it's also shared within the entire Google ecosystem, including advertisers and potentially even governments. Despite this, Chrome has many trackers and ad-blocking plugins available for security-oriented users, such as Avira Safe Shopping. Although Chrome may be one of the most secure browsers, it's also one of the worst for user privacy. Google Chrome is available for Windows, macOS, Android, iOS, and Linux.

Microsoft Edge

Microsoft Edge is a vast improvement compared to its predecessor, Internet Explorer. Edge is a user-friendly, Chromium-based browser that boasts robust security tools, including Edge SmartScreen anti-phishing technology, which detects phishing sites more effectively than Chrome in tests.

In addition to its security features, Edge also offers a simple tracker-blocking system that has three levels: Basic, Balanced, and Strict. The Strict setting blocks most trackers and cookies, including those necessary for some sites to function. In contrast, the Balanced setting performed best in tests, detecting and blocking the most invasive cookies. This makes it much easier to manage online privacy than in Chrome, where the options are limited to

"Allow All," "Block Third-Party," and "Block All."

Like Chrome and Firefox, Edge now supports DNS over HTTPS by default, which enhances user privacy when browsing the web. Microsoft Edge is available for Windows, macOS, Android, and iOS.

Conclusion

It can be difficult to determine whether a browser is truly secure or not, but the browsers mentioned in this article offer a good level of privacy. While this is a great start, for the most secure browsing experience, I suggest using a combination of a secure browser and a virtual private network (VPN). A VPN adds an extra layer of protection to your online activity by encrypting your entire Internet connection, making it much more difficult for anyone to intercept your data or monitor your browsing habits.

By using a quality VPN, you can also hide your real location and appear to be browsing from a different location altogether. This can be especially useful for accessing content that may be restricted in your country or region. With a secure browser and a VPN, you can enjoy a more private and secure browsing experience, free from the prying eyes of hackers, governments, and other third parties that may be trying to track your online activity.

In an era where cybercrime is rampant, businesses must take a proactive approach to safeguard their confidential information. In 2021 alone, over 118 million people have been affected by data breaches, and this number is expected to rise exponentially.

In this post, we’ll discuss some of the best practices for businesses to protect themselves from cyber threats.

Always have a back-up

A good backup system is one of the best ways to maintain computers’ security and protect your business’s data. Regularly backing up important files can help ensure that you don’t lose any information if a cyber incident or computer issue occurs. Here are some tips on how to effectively back up your data:

• Use multiple backup methods. Have an effective backup system by using daily incremental backups to portable devices or cloud storage, end-of-week server backups, quarterly server backups, and yearly server backups. Remember to regularly check and test whether you can restore your data from these backups.
• Use portable devices. Consider using external drives or portable devices such as USB sticks to store your data. Store the devices separately offsite, and make sure they are not connected to the computer when not in use to prevent malicious attacks.
• Utilize cloud storage solutions. Cloud storage solutions are a great way of backing up all your important information. Choose a solution that provides encryption for transferring and storing your data and multi-factor authentication for access.
• Practice safe backup habits. Make it a habit to regularly back up your data, not just once but multiple times throughout the week or month, depending on the type of information you’re backing up. Additionally, it’s important to practice safe backup habits, such as keeping your devices away from computers when not in use and regularly testing that your data is properly backed up.

Train your employees

To protect your business from cyber threats, educating your employees about the risks and how to stay safe is essential. Training should focus on identifying phishing emails, using strong passwords, and reporting any suspicious activity immediately to the IT department.

Ensure that everyone is up-to-date with the latest threats and strategies for protection by conducting regular cybersecurity training sessions with all of your employees. Provide helpful resources such as tips for creating secure passwords, methods for spotting phishing attempts, and steps for safely sharing confidential information online.

Putting this emphasis on education and training will help create an environment of alertness so that any potential risk can be identified quickly and addressed appropriately.

Password management

Weak passwords are one of the most common entry points for cyber attackers, so using a secure password and password manager is essential to keep your business safe.

A password manager is a tool that allows you to store and manage all your passwords securely, with only one strong master password needed to access them all. Here are some tips for creating strong passwords and using a reliable password manager:

• Create strong passwords. Choose passwords that include numbers, symbols, upper-case letters, and lower-case letters. Avoid using personal information like birthdays or pet names in your passwords. Additionally, avoid using the same username/password combination for multiple accounts.
• Use a password manager. A reliable password manager will help you create and store secure passwords. Be sure to select a trustworthy provider, as they will be responsible for protecting your data.

An on-premise password manager like Passwork is an excellent option for businesses that need to store passwords on their own servers. Passwork provides the advantage of having full control over your data and features like password sharing and a secure audit log.

• Enable multi-factor authentication. Adding an extra layer of security to your accounts is easy with multi-factor authentication (MFA). MFA requires two or more pieces of evidence to authenticate the user's identity, such as passwords and biometric data. Most password managers can enable MFA for all your accounts, so be sure to take advantage of this feature.

Finally, make sure you update your passwords regularly and always keep them private. Following these tips will help ensure that you are protecting your business from cyber threats.

Securing your network

Using a Virtual Private Network (VPN) effectively protects your business's sensitive data and prevents unauthorized access to your network. A VPN creates an encrypted connection between your device and the internet, making it more difficult for hackers or malicious actors to intercept and access confidential information. Here are some tips on how to leverage a VPN for optimal security:

• Research the best VPN providers for features that best suit the needs of your organization
• Ensure that the provider meets industry standards such as AES 256-bit encryption
• Set up two-factor authentication with users’ login credentials
• Configure the VPN for reliable and secure connections
• Monitor your network for any suspicious activity or unauthorized access attempts
• Make sure to update the VPN software with new security patches regularly
• Train users on the proper internet safety and best practices when using a VPN
• Use an antivirus program and scan all devices connected to the network for malware threats

VPNs are not only important for protecting data and preventing unauthorized access but also for maintaining user privacy. By encrypting the data sent and received over the internet, your organization can ensure that any information stays secure and confidential.

Consistent vulnerability assessments are crucial

Organizations of all sizes must remain vigilant in mitigating cyber threats — and one of the best ways to do this is by conducting regular vulnerability assessments. This will help identify any potential weaknesses or vulnerabilities that could be used by malicious actors to gain access to your system, allowing you to patch and address them before they become a problem.

Here are a few steps to help get you started:

Develop an assessment plan for your organization

Before starting, it’s important to understand the scope and objectives of the vulnerability assessment. Define the overall goals and objectives before identifying any assets or systems that should be included in the assessment.

Identify and document threats

Once you have developed a plan, it’s time to begin searching for potential vulnerabilities within your system. You can use various open-source intelligence techniques, such as scanning public databases and researching known security issues with similar software versions or operating systems that are present in your system.

Create a testing environment

After potential threats have been identified and documented, you should create a safe testing environment to validate the vulnerability assessment results. Doing so will help ensure that any tests conducted do not adversely affect production systems.

Run automated scans

Following the creation of your secure test environment, it’s time to run automated scans on your organization's target systems or assets. This should include both internal and external scanning tools, such as port scanners, web application scanners, or configuration management tools, depending on the scope of the assessment.

Analyze scan results

Once the automated scans have been completed, it’s time to analyze the results and identify any potential issues or vulnerabilities. Assess any weaknesses present in order to prioritize and address them more effectively.

Develop a remediation plan

After identifying potential security issues, you should develop a remediation plan based on the risk level of each issue. This could include patching vulnerable systems, implementing new security measures, or restricting access to certain areas of your system, depending on the severity of the threat.

By conducting regular vulnerability assessments, organizations can stay ahead of cyber threats and ensure their systems remain secure.

Bottom line

Protecting your business from cyber threats should be a top priority for any organization. With the increasing prevalence of cybercrime and data breaches, implementing effective cybersecurity practices is more important than ever.

By regularly backing up important files, training employees on identifying and reporting potential threats, using a secure password manager, utilizing a VPN, and conducting consistent vulnerability assessments, businesses can significantly reduce their risk of falling victim to cyber-attacks.

In recent years, the issue of user privacy has become more critical than ever before. With the rise of social media and other online platforms, companies are collecting vast amounts of user data, which can be used for various purposes. While some of these purposes may be benign, such as improving the user experience or providing targeted advertising, others may be more nefarious, such as selling user data to third parties or engaging in targeted surveillance.

There are now many apps that are activated by code words — they are called " marker words". These words can activate the listening function on your gadget covertly and completely invisibly. It can be not only "OK, Google" or "Hi, Siri", but also other completely unrelated words or sounds.

Perhaps you may have noticed Instagram advertising something you recently talked to your friends about even in real-time without holding your phone. If so, you know you're being bugged.

So, who's eavesdropping on us?

Facebook

Facebook reportedly hired hundreds of third-party contractors to transcribe voice messages but stopped the practice in July 2019 after it was made public. The contractors were not always clear on why they were listening to certain conversations and did not understand how the messages were obtained. Facebook did not inform its users about this development, which involved the potential listening of personal voicemails by unauthorized individuals.

Microsoft

Microsoft's employees were reported to have listened to personal audio recordings made through Cortana and Skype Translator services. However, Microsoft did not deny this claim and instead included the information in the company's privacy policy. Microsoft believes in maintaining an honest relationship with its users and believes they have the right to know that their conversations may be overheard. Nonetheless, Microsoft did not previously disclose this information to its users, and it is possible that the company decided to proactively share the information as they had been listening to audio recordings for some time. This is in contrast to other companies that faced privacy violations but did not disclose their actions to their users.

Apple

It has been reported that contractors who test Apple's Siri voice assistant for accuracy may be listening in on users' private conversations. It should be noted that Siri can be activated by more than just the phrase "Hey, Siri" and can be triggered by similar-sounding words, background noise, or hand movements. This has resulted in Siri being inadvertently activated during private conversations, leading to the collection of personal information and recordings of private conversations, including those between doctors during commercial transactions. These recordings are often accompanied by data that can reveal the location or personal contacts of the users. Apple representatives claim to be working to address these concerns in order to protect users' personal information.

Amazon

Over one thousand Amazon contractors are listening to voice recordings made in the homes and offices of Echo voice assistant owners. These contractors are required to sign non-disclosure agreements and are not allowed to discuss the program publicly. They work nine-hour shifts and analyze up to 1,000 sound recordings per shift, but even if they have concerns about what they hear, they are required to adhere to the non-disclosure policy. Amazon claims to take the security and privacy of its customer's personal information seriously, and employees do not have access to information that could identify a person or account directly. It is important to note that users can disable the use of their personal voice records for the development of new features in Amazon's Alexa privacy settings.

Google

Google employs experts to listen to the voice commands given by users to its voice assistant. These recordings are made after the voice assistant has heard the phrase "Ok, Google" and can be made on smartphones using Google Assistant or on the Google Home smart speaker. Google shares snippets of these recordings between users and linguists around the world to improve the voice assistant, but claims to have access to no more than 0.2% of all user commands. The company has prohibited employees from transcribing conversations or other extraneous sounds. However, in June 2019, it was reported that a significant leak of audio recordings of users occurred, with over a thousand recordings, including personal conversations between parents and children, addresses, and work calls being exposed. Some recordings were made accidentally due to the assistant being activated by mistake. Google attributed the leak to the actions of one linguist and claimed to be investigating the matter.

Conclusion

Despite the concerns that these data collection practices raise, companies often argue that they are necessary to improve user experience and provide more personalized services.

However, many users remain skeptical of these claims and are increasingly concerned about the potential for abuse. For example, data breaches can expose user data to hackers and other malicious actors, potentially putting users at risk of identity theft and other forms of cybercrime. Additionally, governments and other organizations may use user data to engage in targeted surveillance, raising concerns about civil liberties and individual privacy.

In response to these concerns, governments and regulatory bodies have taken steps to regulate the collection and use of user data. In the European Union, the General Data Protection Regulations (GDPR) have strengthened data privacy laws and given users greater control over their data. In the United States, the California Consumer Privacy Act (CCPA) has similarly sought to protect user privacy by requiring companies to disclose what data they collect and allowing users to opt out of data sharing.

Despite these efforts, however, the issue of user privacy remains a contentious one. As technology continues to advance, companies will undoubtedly find new ways to collect and utilize user data, raising new concerns about privacy and security. It is therefore crucial that users remain vigilant and informed about the data collection practices of companies they interact with, and for governments and regulatory bodies to continue to monitor and regulate these practices to protect user privacy.

People frequently utilize various VPN servers at work. Off-the-shelf options are good, but we've come to learn that a personal VPN offers substantial benefits. To appreciate the benefits of creating your own VPN server over purchasing one, consider why VPNs are used in the first place:

•  To prevent others from intercepting your lines of communication

•  To circumvent access limitations to a specific resource in your own nation or a foreign one

•  Conceal personal information from the Internet provider (the owner of the WI-FI access point)

•  Leave your present location unidentified (don't forget time zones — this is the indicator that may readily pinpoint your location)

Everything is quite straight-forward here, so let's get down to the interesting stuff: what are the advantages of utilizing your own service, and how should you go about establishing one?

Well, today you’re in for a treat — to answer these questions, we’ve put together a checklist with step-by-step instructions for setting up and configuring a VPN server.

Advantages of Using a Personal VPN Server

1. Bypassing blocks

Several countries attempt to fight VPNs by blocking them. But, if you use your own VPN, it will not appear in the main list of providers and will almost surely avoid blocks.

2. There are no captchas

All well-known services will request that you choose horses from a set of photographs, locate traffic lights, or identify a word in a picture. Why is this the case? Several others are using a ready-made VPN server at the same time as we are. Consequently, the website will suspect such traffic and assault you with captchas. When you use your own VPN server, however, this problem is avoided since you will have a unique IP address that will look like an ordinary user.

3. High speed

Off-the-shelf VPN servers often have low bandwidth since they typically don't have time to grow their servers and networks for a big number of customers. With a self-hosted resource, you’ll have all the bandwidth you could possibly need.

4. The ability to send all computer traffic through a VPN, not just browser traffic

5.  No need to install third-party software

As you can see, having your own server solves the majority of the problems associated with using a VPN.

Checklist for creating your own VPN server

Take the example of DigitalOcean and its Droplet server.

Registration

If you already have a DigitalOcean account, you may go to the next stage. If not, you must first register (all the steps are intuitive, don’t worry).

Create a new Droplet that will function as a VPN server

Choose a data center from which you intend to connect to the internet. I selected to work with Frankfurt since it is physically closer to my country of residency, which improves working speed.

Choose Marketplace, and Docker on Ubuntu in the Image column. Finally, in the Size column, choose the subscription plan that suits you.

Next, put a name in Hostname, such as ‘vpn-server’. This has no effect and is simply for your convenience. Next, click the Create Droplet button.

Wait for the server to be created. This might take up to a minute. Following that, you will be given your server's IP address.

Connect to the SSH server

Launch Terminal on MacOS/Linux (or PowerShell/putty on Windows) and connect to our server through SSH using the root username and the IP address of our server.

This can be done with the help of:

ssh root@{your-ip-address}

> enter your password

After that, you have to connect.

Create a docker-compose.yml file

Just copy the code from this website and paste it into your file. This is your server configuration file.

You may create a file directly over SSH using console text editors (nano/vim) or with an SFTP client. I used SSH to access the console editor.

In the same SSH window, input the following:

> nano docker-compose.yml

Paste the content. In the added text, change the following parameters for yourself:

•  my-shared-secret — your secret word

•  my-username — your personal login

•  my-password — your password

Take note of how straightforward it is — there are just 14 lines in the file that we want.

Exit by pressing Ctrl+X, then Y, and then press Enter.

Run the container with the recently created server

Use the same SSH window in which we just created the file.

> docker compose up -d

Congratulations! Your VPN server is up and running. So, how do you connect it?

Connect to the created VPN server

We recommend using IPsec because the clients for this VPN are already built into MacOS/Windows and you don't have to install anything locally. You just need to create a new VPN connection with the following parameters:

•  Type: IPSec

•  Server address: enter the IP address of the server

•  Account name: write my-username (or the one you changed it to)

•  Password: add my-password (or the one you changed it to)

•  Shared Secret: write my-shared-secret (or the variant you changed earlier)

For MacOS, you don't need to install anything, just configure it like this:

For Windows, these settings will look a little different:

Unfortunately, Windows is not so simple and you will have to surf the registry and allow NAT-T.

For Linux users, there is also a screenshot with the required settings (I used them in Ubuntu 22.04):

Before setting up, you need to install the network-manager-l2tp-gnome package. This is done through the console:

> sudo apt-get install network-manager-l2tp-gnome

You can also connect from your phone, you don't need to install anything else. The settings on the iPhone look like this:

And that’s it — you're done! Connect and check the IP address, for example, on Whoer via the link. Now, for the whole Internet, you are physically located in the region where you created your VPN server, and the IP is the IP of the server. It's not as scary, time-consuming, or expensive as you might think.

Security recommendations

When it comes to the security of your server, I would, as a final thought, recommend:

•  Using an SSH key instead of a password

•  Changing the SSH-port from 22 to any other

•  Using a complex password and Shared-secret (preferably a randomly generated string)

Natural language processing (NLP) has made considerable strides in recent years, which has led to the creation of effective language models such as ChatGPT. ChatGPT was developed by OpenAI and makes use of cutting-edge machine learning algorithms to produce text answers that appear to have been written by humans. Concerns about its safety and how it may be abused are beginning to surface as its usage becomes more widespread. We’re aiming to provide a complete overview of ChatGPT's security by delving into its safety features as well as the possible threats that are involved with using it.

How ChatGPT works

It is vital to have an understanding of how ChatGPT operates in order to fully appreciate the security features that it offers. In its most fundamental form, ChatGPT has predicated on a deep learning architecture referred to as the Transformer. This design gives the model the ability to discover patterns and correlations in massive volumes of text data. Because the model has been trained on such a large dataset, which includes web pages, books, and articles, it is able to provide replies to user inputs that are pertinent to the context of those inputs.

Security measures in ChatGPT

OpenAI has put in place a number of preventative safeguards to guarantee the confidentiality and morality of the users of ChatGPT. These precautions include the following:

1. Content Filtering: OpenAI has a content screening mechanism in place to prevent the creation of content that is unsuitable or potentially dangerous. This technique eliminates potentially harmful information by employing both computerized algorithms and human moderators, one after the other.
   
2. User Authentication: Applications that use ChatGPT require user authentication, which restricts access to the system to only those who have been granted permission to do so. This precaution helps stop unauthorized access and lowers the possibility of harmful usage.
   
3. Privacy Measures: OpenAI has a strong commitment to protecting the privacy of its users and ensures the safety of all data throughout storage and processing. In order to secure the personal information of its users, the company abides by severe data privacy requirements, such as the General Data Protection Regulation (GDPR).
   
4. Continuous Improvement: OpenAI is constantly looking for feedback from users in order to enhance the safety and security functions of ChatGPT. The organization is better able to recognize possible dangers and take preventative measures to mitigate them if it keeps its lines of communication with the user community open and active.

Potential risks and misuse

Despite the security measures in place, ChatGPT is not without risks. Some of the potential dangers associated with its use include:

1. Generating Misinformation: ChatGPT has the ability to create information that is either purposefully or accidentally misleading or erroneous. This danger is caused by the fact that the model is dependent on training data, which may contain information that is inaccurate or biased.
2. Amplifying Harmful Content: Even if there are methods in place to screen out potentially hazardous information, there is still the risk that some of it may get through. It is possible that as a consequence of this, hate speech, the ideology of extreme conservatism, and other harmful stuff may be amplified.
3. Privacy Breaches: The risk of data breaches continues to exist despite the implementation of stringent privacy protections. There is always the risk that cybercriminals would try to acquire unauthorized access to user data, which might result in privacy breaches.
4. Social Engineering Attacks: ChatGPT's ability to generate human-like responses can be exploited by bad actors to conduct social engineering attacks. These attacks can involve impersonating trusted entities or individuals to manipulate users into revealing sensitive information or performing actions that compromise their security.

Mitigating risks

To minimize the risks associated with ChatGPT, both developers and users can take proactive steps. Some recommendations include:

1. Regularly updating security measures: OpenAI has to regularly update and enhance its security procedures, taking into account comments from users and tackling new risks as they emerge.
2. User education: It is essential to provide consumers with education about possible hazards and to encourage appropriate usage. This involves increasing awareness about disinformation, issues around privacy, and assaults using social engineering.
3. Strengthening of content filtering: To successfully detect and remove hazardous information, OpenAI has to continue to improve the algorithms that power its content filtering system. This should be done by combining machine learning with human moderation.
4. Collaboration with researchers and policymakers: OpenAI should actively collaborate with researchers, industry experts, and policymakers to develop best practices, guidelines, and regulations that ensure the responsible and secure use of ChatGPT. This collaboration can contribute to a broader understanding of the potential risks and help create a safer AI ecosystem.

Conclusion

The ChatGPT language model is a strong one that has a tremendous amount of promise for a wide range of applications. Although OpenAI has taken a significant number of precautions to assure its safety, there is still the possibility of threats. It is possible to significantly reduce the dangers associated with using ChatGPT so long as appropriate precautions are taken, such as providing users with adequate training, enhancing the algorithms used to filter material, and encouraging collaboration between academics and policymakers.

While utilizing ChatGPT or any other technology that relies on AI, it is essential for users to stay aware and practice care at all times. When it comes to ensuring the safe and responsible utilization of these effective instruments, having an awareness of the possible dangers and taking preventative measures to lessen or eliminate them may go a long way. By doing so, we will be able to use the promise of ChatGPT while also efficiently addressing concerns around security.

The digital era has provided us with numerous advantages. Handheld devices that we carry in our pockets allow us to connect instantaneously with people all over the world, shop for necessities, manage our accounts, conduct our jobs, and so much more.

However, because the internet has become so ingrained in our daily lives, it has also become a massive source of risk. Criminals seeking to steal money or information and endanger national security and stability have more tools than ever to use against us.

As a result, governments must examine cyberspace risks and take action to keep their citizens secure. However, as is often the case, certain governments and general society do better than others.

It is critical to learn which countries are doing well and which are not, as this can help you understand the dangers you encounter when traveling and which policies are effective and not.

Today, we've compiled a list of the five most cyber-secure countries and the five least cyber-secure countries.

The top 5 cyber-secure countries

After reviewing several studies on the cybersecurity of nations throughout the world, we found the following five to be the best:

United States

While cybercrime is a problem in the United States, it is also true that the country has the greatest infrastructure to combat it and most cybersecurity companies in the world call it home. When it comes to cybercrime, the United States is cooperative and somewhat structured in its efforts.

The Global Cybersecurity Index granted it a flawless score, although there are a few flaws. The only improvement we could mention is taking better efforts to inform the population of potential cybersecurity threats. Only 2.89 percent of mobile devices are infected with malware, and even fewer are afflicted with banking or ransomware trojans. Attacks are low across the board, propelling the United States higher in prior years' rankings.

Finland

Finland has earned a spot on our list due to its outstanding legislative response to cybercrime. It also has the lowest mobile malware infection rate, at 1.06%. There are also no harmful mailings, and targeted attacks from all angles are rare.

In general, Finland is doing an excellent job, and the government has recently allocated funding and resources to assist businesses in strengthening their cyber defenses in response to a more hazardous environment. This is an effort that we would want to see more governments officially support.

However, because every country has the chance to improve, we would want to see the government become more organized in its battle against cybercrime, both globally and locally. Powerful legislative measures and technological capabilities can only be fully exploited if the action plan prioritizes cybercrime reduction.

United Kingdom

Another high scorer and a country that has continuously been one of the finest in the world when it comes to cybersecurity, the United Kingdom comes in third place in our rankings.

Mobile malware infects a small percentage of devices (2.26 percent), banking and ransomware trojans are minimal if not nonexistent, and the United Kingdom is the source of very few cyberattacks globally. By all accounts, it has a calming effect on the global cybersecurity community.

In some ways, the United Kingdom resembles the United States in terms of its strengths and weaknesses, as while the legal framework and efforts are generally excellent, we would like to see more government efforts to educate its citizens. The best efforts in the world will be in vain if the average person allows malware in through their front door.

South Korea

The Republic of Korea, a country noted for its exceptional technical achievements in the area of computers, is one of the top countries and the leader in the Asia-Pacific region.

Why? It has a robust regulatory structure in place to combat cybercrime, and the technological capacity to do so and is typically cooperative in international efforts. It may benefit from an additional organizational effort to fully leverage its capabilities, but this does not diminish the country's good effect on global cybersecurity.

However, improvements in total infected devices can be made when compared to top scorers. Banking malware and Trojans are an issue, and malware infects around 3.19 percent of mobile devices. South Korean devices are regarded as targets, and this must be addressed regardless of how ineffectual the majority of attempts are.

Denmark

Denmark rounds out our top five, which should come as no surprise. It is technologically advanced, has a solid regulatory framework in place to combat cybercrime, and is well-organized in dealing with threats and ensuring that individuals and businesses are prepared.

The infection rate of devices across the country reflects these efforts. Only 1.33 percent of mobile devices are infected, and Denmark ranks at the top in almost every infection metric.

Studies continuously show zero infected devices, be it with mobile ransomware or mobile banking trojans.

While its broad diplomatic attitude may prevent it from taking substantial steps, Denmark would benefit from a more coordinated worldwide approach to combating cybercrime. It is a worldwide problem because cyber thieves do not recognize or respect boundaries.

Honorable mentions

China

China may not be at the top of the list, but the Chinese government is actively working to strengthen cybersecurity.

According to them, a large-scale strategy for reorganizing the country's industry has been planned for this. As a result, the following will be developed within the framework of this program:

• 5 safety laboratories

• 3-5 national industrial security parks

• 10 demonstration sites for innovative products

• A number of enterprises with international competitiveness in the industry

The Chinese government has predicted that by 2025, cybersecurity investment will equal 22 billion dollars each year.

The top 5 least cyber-secure countries

Algeria

Algeria is still a troubled country in terms of cybersecurity. There is minimal organizational and government support for cybersecurity measures, and the country is fairly isolated in terms of joint efforts (or overall efforts are simply ineffective).

When you combine these issues with high infection rates, it's easy to see why it's ranked first. Malware-infected phones account for 21.97 percent of all phones. There is a banking virus issue as well as a crypto mining issue. Web-based malware has infected a total of 6.22 devices.

It will take time and effort to address Algeria's cybersecurity issues, and we are not seeing any progress in this regard.

Iran

Iran has not been performing well in terms of cybersecurity in previous years, and recent times have been particularly harmful to the country. Infection rates are exceptionally high, with the highest incidence of mobile malware infection worldwide (30.29 percent). 1.6 percent of consumers were targeted by banking malware, while 29.06 percent were infected by local malware. Other sorts of assaults are less common, but they continue to be a problem.

These difficulties might be addressed with patience and care, but the country's leadership is not as cooperative in international efforts as it could be, and the framework and infrastructure are not comparable to those found in the industrialized world. All of these variables combine to make it a hazardous environment for your device.

Tanzania

While Tanzania has made tremendous progress in addressing its cybersecurity vulnerabilities, there are still certain organizational flaws that cause problems and must be addressed.

This alone would not have qualified it for this list, but according to the most recent available statistics, it had one of the highest infection rates for devices worldwide. Although very recent data is unavailable, Tanzania formerly had a mobile infection rate of 28.03 percent and a PC infection rate of 14.7 percent.

Tajikistan

Tajikistan, for all intents and purposes, does not have a cybersecurity apparatus of any sort. As things are, there is limited technological assistance, minimal legislative measures enforcing cybersecurity, and absolutely no cooperation measures, capacity, or progress. People are on their own when it comes to cybersecurity, and the country would be higher on this list if it weren't for the fact that other countries have more infected devices.

Despite this, there aren't many infected devices, maybe because hackers don't see the country as a key target. Despite this, 41.16 percent of computers are vulnerable to malware attacks, and further concerns loom if more gadgets enter the nation. If you are in Tajikistan, be cautious with your equipment and take precautions to protect yourself.

Pakistan

Pakistan has a cybersecurity concern, with 21.18 percent of PCs vulnerable to local malware attacks and 9.96 percent of mobile devices already infected. While infection rates are lower than they were a few years ago, there is still a lot of work to be done, and anyone visiting should take additional precautionary measures.

Pakistan is also a country that is typically uncooperative on an international level when it comes to dealing with cybercrime, which does not help given that it is not a technology powerhouse like some other nations with a more isolationist approach. Things are unlikely to improve in the near future.

Dishonorable mentions

Vietnam

Vietnam has made significant progress in terms of its cybercrime framework, but it still has one of the highest rates of infected devices in the world.

Malware infects many computers, and 9.04 percent of mobile devices. To lower the risk of infection, the government must identify remedies and act upon them.

Conclusion

We hope you now have a better understanding of the global cybersecurity environment and what makes one country more cyber-safe than another. Of course, it is preferable to avoid going to countries with poor defenses, but if you find yourself in one of these areas, commit to good digital practices and you should be secure no matter where you are.

It’s no secret — largely thanks to Hollywood — that releasing a nuclear warhead requires a series of complicated steps, one of which is entering a launch code, which is typically a long string of letters, numbers, and other symbols. However, it’s actually a lot easier.

A chunk of trivia

In 1962, the then-President of the United States, John F. Kennedy made the announcement that, for purposes of national security, the detonation of a nuclear weapon should only be carried out after the entry of a secret code. In order to put this into action, a technology known as PAL (Permissive Action Link) was developed. The president's goal was that by implementing such a system, they would be able to prevent accidental missile launches and reduce the number of employees who are capable of carrying them out.

Despite this, a detail that is both intriguing and humorous is that during the crisis in the Caribbean, the code for firing nuclear missiles was literally eight zeros. This code did not undergo any revisions for the subsequent 17 years. Indeed, this code wasn’t even hidden; the launch instructions for each missile were printed right on them. It wasn't until the year 1977 that true security codes were mandated for use by US rocket scientists. Up to this moment, any group of individuals with even a little amount of access to nuclear weapons could launch a limitless number of nuclear missiles using a code that even an ape could figure out.

The generation of nuclear codes

The process of generating nuclear codes is complex and secure. The codes are created using a random number generator, which is a computer program that generates numbers randomly without any pattern. This code is then encrypted using highly secure cryptographic algorithms that are almost impossible to break. The encryption keys are divided into multiple parts and distributed among people known as custodians. These custodians are typically high-ranking military officials who are responsible for safeguarding the keys and ensuring that they remain secure.

Typically, the keys are created on a physical device that is purpose-built to have a very high level of security. This piece of hardware is referred to as a key-generation device, or KGD for short. The KGD is resistant to tampering and was developed to be extremely difficult to break into. This guarantees that the codes are created in a protected setting, preventing any illegal access to the information.

We live in a digital age, and children must learn about internet safety as a first port of call. They are constantly on their phones and tablets, and many of them complete their coursework online. To secure personal information, all of these services require a password, but the passwords are frequently pre-set for youngsters, who do not get to create their own.

Children will never learn how to create secure passwords if such passwords are never changed. This renders them vulnerable to hacking. It is our responsibility as parents to educate our children about internet safety. This includes not only stopping kids from accessing improper information, but also explaining why. The greatest method for children to learn about computer security is to see adults who are skilled in the field. Continue reading to learn how to teach your children about password security fast and effortlessly.

Make unique and fun passwords

Passwords should be easy for your children to remember but tough for others to guess. That may appear to be an oxymoron, but if you make it fun, your child will be more likely to remember their passwords. Here are some easy ideas to get their creative juices flowing:

• Make up your own sentences or words. If they had a favorite stuffed animal as a youngster, try to integrate it, but don't make it the sole word. Use three or more to create complexity.

• Use basic, popular passwords such as ABCDE, 123455, or "password" instead. Hackers can easily breach them and obtain access to your accounts.

• Use passwords that are at least eight characters long

• Use numbers, uppercase letters, and symbols as needed. Also, avoid using them in apparent ways. Avoid substituting letters for vowels, such as an exclamation point (!) for I and an at symbol (@) for a. These are basic replacements that are easy to understand.

• Create unique passwords for each website. If your password is hacked and you use it in several places, hackers will have access to your children's sensitive information in multiple areas.

Passwords should not be shared

This one may be difficult for your children to grasp. They do, after all, know your phone's password! However, it is critical that your children do not share their passwords with anyone other than their parents—including their siblings. The more people who know their password, the more likely it is that people who should not have access to their accounts will.

Explain some of the scenarios that could occur to your children to ensure that they understand why they should not share their passwords. Listed below are a few examples:

• Someone could steal their identity

• Someone could send hurtful messages and jeopardize friendships

• Someone could open accounts on questionable platforms using their identity

• Someone could change their passwords and keep them from accessing their accounts

• If there are bank accounts attached, someone could spend their money

These are just a few examples, but they should be enough to convince your children not to share their passwords. If they do, they must inform you of who they shared it with and why. You can then decide whether or not to change their passwords.

Remember, as a parent, this does not apply to you. As a precaution, you should have all of your children's passwords who are under the age of 18. This will give you peace of mind because you will know you can monitor their online activity for their safety and security. There are many frightening people out there, and not just those looking to steal their passwords.

Avoid using the same password in multiple places

It may be difficult to keep track of so many different passwords, but it is critical that you and your child develop a unique password for each website, platform, or program. This will assist to safeguard their data:

• If there is a data breach in one place, they simply need to be concerned about that one location

• If you use the same password, they may have access to far more information, which might be harmful

Your child may not be able to use a password manager at school, but there are security services that can assist you in storing passwords across various platforms. They can also generate secure passwords that are difficult to decipher. These are useful tools, but you should not rely only on them for all of your passwords in case you are locked out.

What does a strong password look like?

You may be asking what makes a password strong now that you know what to do and what to avoid while teaching your children password safety. There are several approaches to constructing a secure password, and you must ensure that passwords are simple for your youngster to remember.

One method is to speak to their interests or their sense of humor.

• Use their passions as a source of inspiration. If they enjoy magic, you may perform something like AbramagiCkadabrA#7. This is an excellent password since it includes random capitalization, a number, and a distinctive character.

• Use something amusing for them. For example, because little children are typically delighted by potty humor, you may establish their username @uniFARTcorn3. Again, you've covered all of the possible factors for password requirements, and your kids will have a good time inputting it.

• Make use of meals and pastimes. You might, for example, create their password Apple3picking! EAO. They enjoy apple harvesting, their favorite number, a special character, and strange apple orchard letters or abbreviations.

You want to make your password difficult to guess but easy to remember, so choosing items that will activate your memory or make you smile when your child enters it will increase the likelihood that they will remember it.

It is not suggested to keep a digital file of passwords on your computer, but if necessary, you may write them down for your children until they learn them. Just be careful not to lose track of where you wrote them!

When most individuals hear the phrase "data disposal," they get terrified. The deletion of data on one's computer or mobile device is the last thing most people desire. But, whether you are the owner of a large, medium, or small corporation, or simply a regular user, you will need to delete or replace your obsolete media at some point. After all, you must guarantee that any data contained in this medium is erased and cannot be recovered.

Nobody wants the next owner of their outdated equipment to discover their secrets, which might have serious legal or competitive consequences.

However, few people understand how to properly erase data such that it cannot be retrieved by others.

What are the different forms of data disposal?

Fortunately, there are various methods for disposing of data. Unfortunately, none of these strategies are ideal, nor can they guarantee total success. However, understanding the strategies available can assist you in selecting the one that is best for you or your business.

Delete / Reformatting

As previously stated, removing a file from an electronic device removes it from a file folder but does not delete the contents. The data is saved on the device's hard drive or memory chip.

The same holds true when you attempt to erase data by reformatting the disc. This also does not erase the data. It simply substitutes a new file system for the existing one. It's like ripping out the table of contents from an old cookbook when you really want to get rid of the cookbook itself. There are several programs available on the internet that allow nearly anybody to recover data from a drive that has just been reformatted.

Using approaches like these is a poor, uninspired, and ineffective manner of attempting data disposal.

Wiping

Data wiping is the process of erasing data from an electronic medium so that it can no longer be read. Typically, data wiping is achieved by physically attaching any media to bulk wiping equipment. It may also be done internally by booting a PC from a network or a CD. It is a procedure that allows you to reuse any medium that has been erased in this manner without losing storage capacity.

Wiping data can take a long time, sometimes even an entire day for just one device. Data wiping may be valuable for an individual, but it is impracticable for a company owner who has to clean several devices.

Overwriting data

In a way, overwriting data is similar to wiping data. A series of ones and zeros are written over existing data when it is rewritten on an electrical device. Set patterns may also be employed; the pattern does not have to be random. Most of the time, one overwriting is sufficient to complete the operation. But numerous passes can be necessary if the medium has a high level of security. This makes sure that no bit shadows can be seen and that all data is entirely deleted.

A bit shadow is a piece of erased information that may still be seen under an electron microscope. It resembles writing a note on a notepad. They can take off the top sheet of paper, but what they wrote could still be legible on the page immediately below. High-security organizations are still concerned about bit-shadowing, but low-risk companies certainly don't need to worry too much. Using an electron microscope to recover data is time- and money-consuming.

Perhaps the most typical method of data destruction is overwriting. It can be time-consuming and is only effective if the media being rewritten is undamaged and still capable of receiving data writes. Additionally, it provides no security protection when overwriting. Any hard disk with complex storage management components does not support overwriting. For each piece of media that is being overwritten, you might need a license if you are overwriting a device because of legal obligations.

Erasure

Erasure is another term for overwriting. Erasure should be comprehensive, destroying all data on a hard drive, and delivering a certificate of destruction demonstrating that data on an electronic device has been effectively wiped. Erasure is a terrific concept for enterprises that have acquired off-lease equipment, such as PCs, enterprise data centers, and laptops, or if you want to reuse or redeploy hard drives for storage of new contents.

Degaussing

Degaussing destroys computer data by disrupting the magnetic field of an electronic media with a high-powered magnet. The data is destroyed when the magnetic field is disrupted. Degaussing may swiftly and effectively erase data in a device containing a huge quantity of information or sensitive data.

However, it has two big drawbacks.

When you degauss an electrical device, its hard drive becomes unusable. Degaussing damages the hard drive's connecting circuitry. If you wish to reuse an electrical digital device such as a laptop, computer, or mobile phone, this is not the way to go about it.

Another issue is that there is no means of knowing if all of the data has been erased. You can't tell if all the data has been lost if you make the hard disk useless. In this instance, the only way to verify data destruction is to utilize an electron microscope. However, unless you are destroying high-security information, this method of verifying is both costly and unworkable.

The density of a hard disk can also affect degaussing. As technology advances and hard drives get larger and more powerful, degaussing may no longer be as effective as it once was.

Physical destruction

Many people want to recycle their old equipment but are hesitant because of the information it may hold. These folks frequently take out the hard disk with a hammer and crush it to pieces.

Surprisingly, physical destruction is also a cost-effective method for organizations and corporations of all kinds to remove data. One of the most advantageous aspects of physical destruction is that it provides an organization with the highest possibility that data has been physically deleted.

However, it may be costly, and because it entails the destruction of electronic media, the capital cost is also considerable. It might also be a concern if an organization has a green and sustainable recycling program for obsolete electronic media.

Physical destruction is a type of degaussing. Incineration is another option, although it is less prevalent since it needs destruction to take place away from human areas.

Conclusion

Properly disposing of sensitive information is an essential component of information security. By taking the time to identify what data needs to be disposed of, selecting the right methods for disposal, and having a secure and controlled plan in place, organizations can ensure that sensitive information is protected and kept out of the wrong hands.

This question is indeed controversial, sparking a heated debate in all camps. Regardless of who is right, according to an IBM report from last year, the average data breach is set to cost more than $4.35 million.

That is why, now, more than ever, programmers must be aware of the risks associated with various programming languages and take precautions to protect their code from vulnerabilities. The good news is that known best practices can assist programmers in safeguarding their code against data leaks and attacks.

Continue reading to learn more about programming language vulnerabilities and how to future-proof your code.

Python

Python is a programming language that is widely used because of its user-friendliness and legibility. On the other hand, it’s also one of the most vulnerable languages due to its popularity and the number of libraries available. According to the results of a recent study, more than 46 percent of all Python code contains at least one security issue.

The following are some of the most significant Python risk factors:

Vulnerable libraries
One of the most serious risks associated with Python lies in its libraries. When a new library is released, it may contain flaws that can be exploited by attackers.

Dependencies
Python code frequently relies on third-party components, which can introduce additional risks. A security breach could occur if one of these dependencies is compromised.

Best practices for Python include:

The use of a virtual environment
A virtual environment is a separate development environment that can help to reduce the risk of dependency issues. Install all dependencies in the virtual environment rather than in a global one when using a virtual environment.

Perform software composition analysis (SCA)
The process of identifying and analyzing dependencies in code is known as SCA. Performing SCA, for example, with Kiuwan allows you to identify and mitigate code security risks quickly.

PHP

Because of its ease of use and wide range of available libraries, PHP can be an excellent choice for web development. As a result of its popularity and the number of web applications built with it, it is extremely vulnerable.

The following are some of the most significant PHP risk factors:

SQL injection
SQL injection is one of the most common attacks against PHP applications. By injecting malicious code into a SQL query, attackers can execute malicious code.

Remote code execution
Remote code execution is another common attack against PHP applications. This attack enables attackers to run code on the server, potentially compromising the entire system.

Best practices for PHP include:

Validating user input
It is critical to validate all user input to ensure no malicious code is present. This will assist in preventing SQL injection and remote code execution attacks.

Use prepared statements
By separating data from code, prepared statements can help protect against SQL injection attacks. Even if an attacker is able to inject malicious code, it will not be executed.

Java

Java has long been a popular choice for corporate development because of its platform neutrality with a vast range of accessible libraries. Regardless, Java is susceptible because of the enormous amount of legacy applications.

The following are some of the most significant Java risk factors:

Outdated versions
Many Java applications are built on out-of-date platform versions. As newer versions frequently include security fixes for known vulnerabilities, this can leave them open to attack.

Insecure libraries
There are certain additional dangers while using Java applications because they frequently use third-party libraries. A security breach may occur if any of these libraries are hacked.

Best practices for Java include:

Use a dependency manager
The utilization of third-party libraries can be made safer with the assistance of a dependency manager.

Utilize strong encryption techniques
For any sensitive data being kept or sent, strong encryption should be employed. This will assist in preventing attackers from gaining access to this data, even if they are able to hack the system.

Ruby on Rails

Ruby on Rails is a well-known web development framework that is lauded for how simple it is to implement. Unfortunately, Ruby on Rails is insecure by default and contains harmful functionalities, making it susceptible to attack.

The following are some of the most significant Ruby on Rails risk factors:

Dangerous functions
Some Ruby on Rails functions, such as "eval" and "exec," might be harmful if used incorrectly. If these functions are not appropriately protected, an attacker might use them to execute malicious code on the server.

Unsecured defaults
Many Ruby on Rails settings are insecure, such as the "secret key base" and "session cookie store." If they are not properly set, they may result in data security breaches.

Best practices for Ruby on Rails include:

Disabling dangerous functions
It’s essential to turn off any potentially hazardous features that are not required. Because of this, attackers won't be able to utilize them to carry out the actions required to execute malicious code.

Utilize security best practices
When setting up Ruby on Rails, it is essential to adhere to all of the recommended security best practices. This includes the use of strong passwords and encryption for any data that may be considered sensitive.

C

C was deemed to be the most vulnerable programming language in a recent report. This was owing to the number of significant vulnerabilities that are frequently detected in programs that are based on C.

The following are some of the most significant C risk factors:

Memory corruption
Memory corruptions are possible in C, which opens the door for malicious code to be run on the system and allows hackers to get access.

Buffer overflows
Buffer overflows are a sort of software security issue that is widespread in C. They arise when more data than a buffer can handle is pushed to it, letting attackers overwrite other sections of memory and execute code.

Best practices for C include:

Static application security testing (SAST)
SAST can assist in identifying security flaws in C-based applications. It may provide thorough testing and be integrated into the software development life cycle.

Use a security-focused coding standard
Several coding standards focus on security, such as the CERT C Secure Coding Standard.  Adherence to these standards can assist to decrease the risk of vulnerabilities in C-based programs.

JavaScript

JavaScript, like practically every other programming language, has a range of security flaws. Exploiting JavaScript’s vulnerabilities allows you to change data, redirect sessions, modify and steal data, in addition to a variety of other things. While JavaScript is often considered a client-side program, security flaws with JavaScript can cause difficulties in server-side contexts as well.

The following are some of the most significant JavaScript risk factors:

Source Code Vulnerabilities
Source code flaws are frequently paired with other JavaScript security issues, even side by side. The increasing usage of publicly accessible packages and libraries is another source of source code security flaws. Furthermore, developers frequently install packages for even the most basic of operations, therefore increasing project dependencies. Of course, this can lead to security issues and other far-reaching implications.

Session data theft
Client-side browser scripts may be quite powerful since they have access to all of the material sent to the browser by a web application. This includes cookies that may include sensitive data, such as user session IDs. In reality, a popular XSS attack technique is to provide the attacker with the user's session ID tokens so that the attacker may hijack the session.

Best practices for JavaScript include:

Quality auditing through tools
While monitoring and resolving all potential application dependency vulnerabilities can be time-consuming and challenging, auditing tools can assist in automating and therefore speeding up the process.

Set secure cookies
Set your cookies to "secure," which restricts the usage of your application's cookies to just secure web sites, to guarantee that SSL/HTTPS is in use.

Conclusion

Even though weaknesses in security are frequently shared across many computer languages, certain languages are more susceptible to attacks than others. If they are not set up or utilized appropriately, any one of the top five programming languages is left open to the possibility of being attacked. As a result, it is essential to follow the best practices for each language in order to assist in lowering the hazards.

We have made enormous leaps forward in terms of technology over the past decade. However, the growth of cyberspace brings with it new challenges for cybersecurity; cybercriminals have adapted their techniques to the new environment. Nevertheless, there is a solution to every challenge.

In light of this, let's take a look at some of the most serious cybersecurity threats and the solutions that have been offered for them in 2023.

The biggest threats to cybersecurity today and how to combat them

Adaptation to a remote workforce

Employees encounter one of the most common security threats when working from home. Employees may mistakenly let hackers access their computers or corporate files due to inattention, weariness, or ignorance. However, protecting remote and hybrid working environments will remain the most difficult tasks in the world of cyber security.

Cloud-based cybersecurity solutions that safeguard the user's identity, devices, and the cloud are essential for secure remote working.

Blockchain and cryptocurrency attacks

Attacks on blockchain-based systems can be launched by both outsiders and insiders. Many of these assaults use well-known tactics such as phishing, social engineering, data-in-transit attacks, and those that focus on coding faults.

To defend organizations against cyberattacks, stronger technological infrastructure may be constructed using blockchain-powered cybersecurity controls and standards. Combining the blockchain with other cutting-edge technologies like AI, IoT, and machine learning may also be required.

Ransomware development

Ransomware is a type of virus that encrypts files on a victim's computer until a ransom is paid. Historically, organizations could keep their data fairly safe by using a standard backup procedure. The organization may be able to restore the data held hostage without paying the ransom, but this does not guarantee that the bad guys will not try to take over the data.

As a result, users must prioritize frequently backing up their devices, employing cutting-edge anti-malware and anti-phishing solutions, and keeping them up to date at all times

BYOD policies

Personal devices are more likely to be used to breach company networks, whether or not BYOD is permitted by IT, because they are less secure and more likely to contain security weaknesses than corporate devices. As a result, businesses of all sizes must understand and address BYOD security.

Among the management options are BYOD services, and the process begins with enrollment software that adds a device to the network. Company-owned devices can be configured individually or in bulk.

The dangers involved with serverless apps

For some developers, the event-driven nature of serverless computing and the lack of permanent states are drawbacks. Developers that need persistent data may encounter problems since the values of local variables may not survive between instantiations.

Enlisting the support of your company's cybersecurity expertise may be the best line of action for those who use serverless architectures.

Supply chain attacks are increasing

An attack on the supply chain happens when someone breaches your digital infrastructure by leveraging an external supplier or partner who has access to your data and systems. This type of attack is known as a supply chain assault.

Upkeep and maintenance of a highly secure build infrastructure, fast software security upgrades, and the creation of safe software updates as part of the software development life cycle are all essential.

Preventive social engineering measures

Cybercriminals use social engineering to get critical information from their targets by influencing their psychology. It causes users to make security mistakes and steal sensitive information such as banking passwords, login information, system access, and other similar information.

To avoid cyberattacks, organizations should employ a technology-and-training-based strategy. There is no one-size-fits-all solution to defeating these social engineers; instead, you must adopt an integrated approach that includes multi-factor authentication, email gateways, respected antivirus software, staff training, and other components to thwart such social engineering assaults.

Cyber security challenges in different industries

Cybersecurity issues are common anywhere cyberspace is used. Some significant industries that face specific cybersecurity challenges in business are listed below.

Vehicular communications

As Vehicle-to-Everything (V2X) communication technologies evolve and current cars are able to interface with external infrastructure, the necessity of securing communications becomes increasingly apparent. There is a very real possibility that the vehicles of today may be the targets of cyberattacks that are directed at vehicular communications.

Cybersecurity challenges in the healthcare industry

Cybercriminals continue to develop new methods to attack healthcare cybersecurity policies, whether it be high-value patient data or a low tolerance for downtime that might interfere with patient care. Both of these vulnerabilities present opportunities for cybercriminals. Hackers now have access to a market worth $13.2 billion thanks to the 55% rise in cyberattacks on healthcare providers that have occurred over the past several years. This has turned the healthcare industry into a veritable gold mine.

Banking

Threats are constantly evolving and the cybersecurity landscape is constantly changing. With huge sums of money and the potential for significant economic shocks at stake in the banking and financial business, the stakes are high in this area. A significant hacking assault on banks and other financial institutions might result in severe economic consequences.

Online retailing

Retailers present a favorable and low-risk target environment for those who commit cybercrime. These businesses are responsible for the processing, storage, and protection of the data and sensitive information of their customers. This information may include financial credentials, usernames, and passwords. These details are susceptible to being attacked because of the ease with which they might be utilized in both online and offline operations.

Conclusion

Recent years have demonstrated how the key cyber security issues and threat actors are adapting their techniques to a changing global environment. The greatest strategy to safeguard your organization and plan for cybersecurity in 2023 is to be proactive. A single data breach can cost millions of dollars in lost data, penalties, and regulatory action. Understanding the hazards that are on the horizon will allow you to account for them in your procedures and stay one step ahead of attackers.

Of course you want to keep your data safe. So why are so many security precautions frequently overlooked? Many accounts, for example, are protected by weak passwords, making it easy for hackers to do their work. There is a fine line between selecting a password that no one can guess and selecting a password that is easy to remember. As a result, we will examine this topic in depth today and ensure that you no longer need to click on the "lost password" link.

What exactly is a strong password?

So let's begin with a definition. A secure password is one that cannot be guessed or broken by an intruder.

Computers are utilized by hackers in order to try out various combinations of letters, numbers, and symbols. Passwords that are only a few characters long and consist entirely of letters and digits are easy for modern computers to crack in a couple of seconds. Because of this, it is vital to utilize robust combinations of capital and lowercase letters, numbers, and special characters in one password. There is a minimum length requirement of 12 characters for passwords, although using a longer password is strongly encouraged.

To summarize the attributes of a secure password, they are as follows:

•  At least 12 characters are required. The more complicated your password, the better.

•  Upper and lower case letters, numbers, and special characters are included. Such passwords are more difficult to crack.

•  Does not contain keyboard paths

•  It is not based on your personal information

•  Each of your accounts has its own password

You have undoubtedly observed that a variety of websites "care" about the security level of your password. When you are making an account, you will frequently see tooltips that remind you to include a particular amount of characters, as well as numbers and letters. Weak passwords have a far higher chance of being disapproved by the system. Keep in mind that, for reasons related to your security, you should never use the same password for several accounts.

A secure password should be unique

You may use a strong password for all of your accounts after you've created one. However, doing so will leave you more exposed to assaults. If a hacker obtains your password, they will be able to access whatever account you used it for, including email, social media, and work accounts.

According to surveys, many people use the same password because it is easier to remember. Don't worry, there are several tools available to assist you with managing multiple passwords. We'll get to them later.

While adding special characters in passwords is an excellent approach to increase their security, not all accounts accept all characters. However, in most scenarios, the following are used: ! " #% & *, / : | $ ; ': _? ().

Here are some examples of strong passwords that make use of special characters:

•  P7j12$# eBT1cL@Kfg

•  $j2kr^ALpr!Kf#ZjnGb#

Ideas for creating a strong password

Fortunately, there are several methods for creating unique and secure passwords for each of your accounts. Let's go over each one in detail:

1. Use a password generator/password manager

If you don't have the time to come up with secure passwords, a password generator that can also serve as a manager is a very simple and straightforward solution that you may use.

2. Choose a phrase, not a word

Passwords are significantly less secure than passphrases since they are often lengthier and more difficult to guess or crack. Instead of a word, pick a phrase and use the first letters, digits, and punctuation from that phrase to generate an apparently random combination of characters. Experiment with different wording and punctuation.

Here are some examples of how the passphrases  technique may be used to generate secure passwords:

•  I first went to Disneyland when I was four years old and it made me happy: I1stw2DLwIw8yrs&immJ

•  My friend Matt ate six donuts at a bakery cafe and it cost him £10: MfMa6d@tbc&ich£10

3. Pick a more unique option

Open a dictionary or book and select a random word, or better yet, many. Combine them with numbers and symbols to make it far more difficult for a hacker to decipher.

As an example:

•  Sand, fork, smoke, okay — Sand%fork9smoke/okay37

4. Experiment with phrases and quotes

If you need a password that is difficult for others to guess but easy for you to remember, try variants on a phrase or statement that means something to you. Simply choose a memorable sentence and replace parts of the letters with numbers and symbols.

For example:

•  “For the first time in forever”: Disney’s Frozen: 4da1stTymein4eva-Frozen

5. Make use of emojis

You may always use emoticons to add symbols to your passwords without making them difficult to remember. You can't add emojis, but you can attempt emoticons made out of punctuation marks, characters, and/or numbers.

For example:

•  \_(ツ)_/¯

•  (>^_^)> <(^_^<)

•  (~.~) (o_O)

What should I do after I have created a password?

1. Set passwords for specific accounts

You'll still need to generate a unique password for each of your accounts once you've created a strong password that you can remember. Instead of creating several new ones, you may include the name of the platform you use at the end. For example, if your password was nHd3#pHAuFP8, just add the word EMa1l to the end of your email address to get nHd3#pHAuFP8EMa1l.

2. Make your password a part of your muscle memory

If you want to be able to recall your password, typing it out several times can help you do so. You will be able to memorize information far more easily as a result of the muscle memory that you will develop.

How to keep your passwords safe?

1. Choose a good password manager

Use a trustworthy password manager whether you're setting your own safe passwords or looking for an internet service to handle it for you. It creates, saves, and manages all of your passwords in a single safe online account. All you have to do is put all your account passwords in the application and then safeguard them with one "master password". This means you just have to remember a single strong password.

2. Use two-factor authentication

You've heard it before, but we'll say it again. Two-factor authentication (2FA) adds an additional level of protection. Even if someone steals your password, you can prevent them from accessing your account. This is often a one-time code supplied to you by text message or other means. Receiving an SMS, by the way, is not the most secure method since a hacker might obtain your mobile phone number in a SIM swap fraud and gain access to your verification code.

Apps using two-factor authentication are far more secure. Google Authenticator, for example, or Microsoft Authenticator.

3. Passwords should not be saved on your phone, tablet, or computer

Although it might not be immediately visible, this is a common approach for people to save their passwords. That should not be done. Your files, emails, messenger conversations, and notes may all be hacked.

4. Keep your password confidential

Even if you completely trust the person to whom you are handing your password, sending it in a text message or email is risky. Even if you speak it aloud or write it down on paper, someone who is interested can overhear you and take notes behind you.

Ransomware assaults are something that all of us have been keeping an eye on for some time. According to the most recent findings, over 21 percent of companies throughout the world were victims of ransomware attacks in 2022. 43% of these had a substantial influence on the way in which their business activities were carried out.

It’s true that cybercrime is on the rise, and those who commit these crimes are going after both individuals and businesses. In order to maintain a competitive advantage, it is essential to have a solid understanding of the types of cyber threats that will be prevalent in 2023.

The purpose of this article is to familiarize you with the most important developments in the field of cybersecurity that are expected to take place in 2023. There are a lot of different things to keep an eye on here, from emerging malware to security solutions based on artificial intelligence. In this section, we will discuss the potential effects of these trends on the future of cybersecurity and the steps you can take to better defend yourself.

Top 5 cybersecurity trends for 2023

1. The Internet of Things (IoT) and cloud security

It's critical to stay up to date on the newest cybersecurity developments in an ever-changing technological context. As more firms utilize cloud computing and Internet of Things (IoT) technology, the importance of adequate security measures grows.

When it comes to IoT and cloud security, it is critical to recognize the particular dangers that these technologies entail. One of the most serious concerns about IoT devices, for example, is that they are frequently "always on," leaving them exposed to external assaults. Similarly, if security mechanisms are not adequately established, cloud services might be accessible to hackers.

It is critical to have robust security procedures for your IoT devices and cloud services in order to keep your organization secure. This includes adopting strong passwords on all devices, enabling multi-factor authentication for access control, and ensuring that any data saved in the cloud is encrypted.

2. SaaS security solutions are becoming increasingly popular

As businesses and consumers rely more on cloud computing and software solutions, the requirement for effective security becomes even more critical. When compared to traditional on-premises solutions, SaaS security solutions provide rapid scale-up or scale-out based on demand and cost savings. These solutions are also well suited for working with remote or dispersed teams where several business components may be located all over the world.

Data protection, identity and access management, web application firewalls, and mobile device security are all available through Security as a Service (SECaaS) solutions. They also provide managed services, which allow customers to delegate the monitoring and maintenance of their cloud security systems to qualified specialists. This helps guard against dangers like malware and ransomware while also keeping businesses up to date on the newest security developments.

3. Increased security for remote and hybrid employees

As the world continues to migrate to remote and hybrid work arrangements, cybersecurity must change to meet these new needs. Organizations must safeguard their systems and train their staff with cyberthreat defenses as their dependence on technology and access to sensitive data grows.

Multi-factor authentication (MFA), which requires multiple authentication stages to validate a user's identity before giving access to systems or data, is one security protocol that organizations should consider using. MFA can offer an extra degree of security against attackers who use stolen credentials to gain access to accounts.

Businesses should also consider adopting rules and processes to ensure the security of their workers' devices. This may involve offering safe antivirus software and encrypted virtual private networks (VPNs) for remote connectivity to employees. Employees must also be trained on the significance of using strong and unique passwords for each account, alongside the risks of connecting to public networks.

4. Machine learning and artificial intelligence

Artificial intelligence and machine learning have grown in popularity in the realm of cybersecurity in recent years. AI and machine learning (ML) offer automated threat detection and enhanced security processes, making them effective instruments in the battle against cyberattacks. Organizations may employ AI and machine learning to proactively detect and avoid dangers as these technologies evolve.

AI and machine learning can assist in the rapid and accurate analysis of vast volumes of data, enabling more effective threat identification and prevention. For example, AI may detect harmful or suspicious network activities, such as increased traffic from a certain source or trends in user behavior. Organizations can also use machine learning algorithms to identify abnormalities and prioritize warnings that may signal a possible breach.

Furthermore, AI and machine learning can automate key cybersecurity operations like patch management, malware detection, and compliance checks. Organizations can save time and money that would otherwise be spent on manual processes. Furthermore, the application of AI and machine learning may assist businesses in lowering the risk of false positives and ensuring that only the most critical security incidents are highlighted.

5. Creating a Safe Culture

Businesses in today's environment must cultivate a culture of safety. Security cannot be handled after the fact or as a one-time job. It should be the organization's fundamental value, ingrained in all parts of its operations. This implies that everyone in the business must be informed of current cybersecurity trends and understand how to secure their data.

Employee training and checks and balances should be part of a safe culture. All personnel should be trained in the fundamentals of Internet security, as well as how to utilize systems and software safely. Policies, systems, and processes should be evaluated on a regular basis to ensure they are in compliance with the most up-to-date security guidelines.

Conclusion

As technology advances, cybersecurity risks and patterns will alter. Businesses must keep ahead of the curve by monitoring emerging trends and updating their security measures as needed. Organizations can secure their data and networks from intruders by staying up to date with the newest 5 cybersecurity trends in 2023.

Organizations may maintain the security of their data by keeping with the times on trends and implementing the required safeguards. Furthermore, they should work to educate their personnel on the need to adhere to best practices in cybersecurity. This will aid in the creation of a secure environment and reduce the likelihood of hacking.

The film industry in general isn't recognized for its commitment to truth, and Hollywood's depiction of biometric technology is no exception. The use of technologies such as fingerprint scanners, face recognition software, and iris recognition technology has become increasingly frequent in a variety of films to portray dramatic and high-tech images of the future.

Let's take a more in-depth look at the way biometrics are portrayed in movies, and what of what we see there is science fiction and what is a reality that most people probably know very little about.

Biometrics in Hollywood blockbusters

First, we ought to define biometrics and how biometric characteristics may be used to identify people. Biometrics refers to the identification of a person utilizing a character's unique physical and behavioral features. Each individual has some quantitative and fixed markers that do not vary over time or alter very minimally. These signs are so distinct that they may identify one individual from another.

In addition to the well-known DNA, fingerprints, and face, unique biometric characteristics include the pupil/iris of the eye, palm print, hand print, scent, "pattern" of veins on the fingers and palm, and so on.

Many biometric parameters of a person may be used by modern technology for identifying people, but they vary in cost, speed, and accuracy of usage. Biometric technologies are often used to control access to important objects or to identify criminals. These aspects are well-represented in films, including, of course, Bond movies.

Skyfall

In one of the Bond films — "Skyfall", a security camera in the London Underground is used to search for an individual’s face.

The film shows how the biometric identification system scans and validates faces with security cameras before recommending the "best fit" solutions. Bond was readily located since his face was uncovered, he was facing the crowd, and the camera easily recognized him. However, the situation was more complex while looking for an intruder among the crowd – in a hat pulled practically over the eyes, it is nearly impossible to recognize a person. To calculate its algorithm, the system must "see" the entire face (which includes data such as the distance between the eyes, the distance from the eyes to the lips, etc.). The technology recognizes the intruder when he raises his head and the camera "sees" his eyes.

It should be underlined that this is not only possible, but it already works in reality.

Demolition Man

The amputation of body parts (from one person) to identify and get access to top-secret things by another person or to collect information is the next iteration of biometrics that is frequently exploited in movies. The film "Demolition Man" is one example of an eye being removed and used.

In reality, this doesn't work. Because the majority of today's technologies are created with a "live" identification mechanism (pulse, reflexes, temperature, humidity coefficient, etc.), it is not possible to identify a dead portion of the body using these methods. Those who use fingerprint readers in their day-to-day lives can attest to the fact that the performance of the gadget is significantly diminished during the winter months because the fingers freeze.

In addition to the built-in mechanism that was just described, there is also a biological limitation: a severed finger is considered "invalid" after approximately ten minutes; an amputated eyeball decomposes rather quickly, and the pupil spreads out, making it unsuitable for use as a unique identifier; the eyeball also decomposes rather quickly.

Minority Report

Developing the topic of biometric authentication with the help of the eyes, it is worth noting that an eye transplant procedure is a common approach in filmmaking for changing identity and gaining access to something. The film "Minority Report" is one such example.

Eye surgeons are unlikely to transplant an entire eyeball, owing to the inutility of such a procedure. For the eye to operate, the optic nerve must also work, which cannot be "stitched on" (much as a brain transplant cannot be performed), at least not yet. An eyeball transplant procedure is theoretically conceivable, but this eye will be unable to see, which is why nothing like this is done. We can only guess whether such an eye may be utilized for biometric identification.

Back to the Future 2

One of the most prophetic and reliable films in the field of biometric technology was "Back to the Future 2"

The video depicts the active usage of biometric technology multiple times. To begin, this is the identification of a person using fingerprints (instead of, say, a passport). Remember how the cops fingerprinted Jennifer Parker, who was sedated by Doc prior to "arriving" in 2015? Secondly, the officers used the same fingerprint to enter Jennifer's Hill Dale home. Thirdly, payment for products and services was using biometrics rather than credit cards: elderly Biff pays for a cab by merely putting his finger on a biometric sensor.

Conclusion

In each of these three counts, the authors have made excellent points. You are required to leave your biometric data in order to receive a visa to enter the United States, the European Union, and some other countries. These biometric data might be in the form of fingerprints or retinal scans. Of course, not all US residents have had their fingerprints taken yet.

In addition, payments made using a customer's fingerprint have already started to become more commonplace in the banking industry. The widespread Apple Pay service is a good illustration of this point. To validate the transaction, all that is required of you is to scan your fingerprint by pressing a single button that is located on the front of your smartphone. In newer models, you simply have to scan your face.

Last but not least, a number of firms have already introduced door locks that can be opened using a fingerprint. One of Samsung's many business divisions focuses on "Smart Home" goods, one of which is the production of electronic door locks.

Science fiction from films is clearly becoming a reality; certainly, the imagination and ingenuity displayed by writers and filmmakers may be what pushes scientists to research and bring that vision into reality.

Biometric technology has a bright future. This confirms that the most tempestuous and impossible visions of filmmakers in the early 2000s or the 1980s are not the future; rather, they are becoming normal in everyday life.

Since the time of the Roman Empire, people have been able to use encryption to keep their communications private. When the Roman emperor Gaius Julius Caesar was penning an important message, he would sometimes replace a letter in the source text with another letter that was positioned three characters to the left or right of the original letter in the alphabet. This practice dates back to well before our period. If the communication was intercepted by his adversaries, they would not be able to decipher it since they would think it was written in some other language. This method of concealment was known as the Caesar cipher, and it was categorized alongside the other substitution ciphers. The substitution ciphers' overarching strategy is to change the meaning of a character by using a different character.

However, in encrypted messages, common terms were replaced by a single letter, eliminating the possibility of substitution. In this manner, Mary Stuart, imprisoned in Sheffield Castle, communicated with Anthony Babington about the conspiracy and Elizabeth's death. This is a part of that letter.

Indeed, Elizabeth's counterintelligence department, commanded by Francis Walsingham, intercepted the letter, which was quickly decrypted by Elizabeth's greatest cryptanalyst, Thomas Fellipes. How did he manage it? Through an analysis of frequencies.

All letters appear in the language with varying frequency. As a result, you just need to define the percentage of characters in the text that will be replaced by a certain character, and it will take some time to substitute and test hypotheses. This is called frequency analysis. It only works on somewhat long texts, and the longer the text, the better.

Anthony Babington was hung, drawn and quartered, Mary Stuart was beheaded, and the process of letter replacement was no longer deemed secure. However, an antidote to frequency analysis was discovered immediately. It is sufficient to utilize several encryption methods: encrypt one string with one, and the other with another, and frequency analysis will be rendered ineffective.

Since then, there has been an ongoing race between encryption and cipher cracking.

The cracking of the Enigma cipher machine used by Nazi Germany to safeguard military and political communications is the most notable feat in breaking encryption algorithms. By the standards of the time, it was a superb encryption device, on which the brightest brains in Germany collaborated. But deciphering the encryption required no less of a force: a team of British cryptographers collaborated with the young scientist Alan Turing.

Despite the cloak of secrecy, his name is linked to the selection of the key that could unlock the Enigma. Indeed, the key was a seemingly mundane Hitler greeting, which had to be included at the conclusion of every piece of correspondence. Alan Turing accomplished the impossible by providing his country with a crucial advantage during World War II.

Modern algorithms like AES, Twofish, and Blowfish differ significantly from substitution or the displacement of letters, as well as Enigma ciphers. Furthermore, they have nothing to do with them and are immune to brute-force and frequency analysis attacks. One thing stays constant, however: there are still individuals who wish to hack them and decipher encrypted messages. Nowadays, the availability of such a dependable data protection instrument cannot help but bother those who wish to acquire access to any information of special services.

Methods of attacks on ciphers by intelligence agencies

Today, intelligence agencies use three primary methods to attack ciphers.

Direct key selection to ciphers

Data centers that use brute force to break encrypted data are being created for this purpose. You can crack practically any contemporary encryption by brute force; simply guess the key (which is generally logical: if there is any key, in theory, sooner or later it can be guessed). The only question is how much power you have and how much time you have. For example, whereas a single contemporary computer can check 10,000 keys per second on average, a data center of thousands of machines may match tens of millions of keys per second.

Fortunately, cracking a powerful cipher can take more than a dozen years in a contemporary data center, and it is impossible to envision what has to be done so that a whole data center is engaged in cracking your encrypted data. After all, a single day in a data center costs tens of thousands of dollars. Because of the expense of resources, a basic password selection using a dictionary is generally done.

This was the situation with Daniel Dantas, a Brazilian banker who was detained in Rio de Janeiro in July 2008 on accusations of financial fraud. Five hard discs with encrypted data were discovered during a search of his flat. Local specialists were unable to break them and went to the FBI for assistance. The FBI returned the CDs after a year of futile attempts. The method of picking a password using a dictionary was utilized for hacking. Daniel Dantas devised a strong password that would be immune to dictionary assaults. It is unclear whether this aided him in court, but access to his encrypted data was never acquired. He utilized TrueCrypt, an encryption application, by the way.

Aside from data centers, there is an ongoing development of a quantum computer that has the potential to drastically revolutionize modern cryptography. If cryptographers' forecasts come true, it will be easy to crack any current crypto container very fast following the advent of such a supercomputer. Some scientists believe that such a supercomputer has already been developed and is located someplace in the hidden cellars of the US National Security Agency.

The second attack method is a scientific study of modern encryption algorithms with the aim of breaking them

A lot of money is being invested in this business, and such decisions are truly invaluable for special services and intelligence. Here, researchers compete with intelligence agencies. If researchers break the protocol or discover a weakness early on, the rest of the world is likely to learn about it and switch to more secure methods. If they are discovered by intelligence agencies, they are discreetly utilized to obtain access to encrypted data.

A 768-bit RSA key was regarded as an entirely reliable solution ten years ago, and it was utilized by private users, huge corporations, and governments. However, a consortium of engineers from Japan, Switzerland, the Netherlands, and the United States successfully computed data encrypted using a 768-bit RSA cryptographic key at the end of 2009. The usage of 1024-bit RSA keys was suggested. However, 1024-bit RSA keys are no longer deemed strong enough either.

The third attack method is a collaboration with device, program, and encryption algorithm creators to weaken encryption and add backdoors

It is sufficiently difficult for special services to decrypt a correctly encrypted crypto container, so instead, they try to bargain with firms producing encryption tools so that the latter leaves decryption flaws or degrades the algorithms utilized. The US’ NSA is ahead of the rest of the world in this regard. According to Edward Snowden's allegations, the American creator of cryptographic technology RSA Security was paid $ 10 million by the NSA to build a backdoor into its software. RSA Security provided its clients with the notoriously flawed Dual EC DRBG pseudo-random number generation technique for this money. Because of this flaw, US spy services were able to readily decode communications and information.

We don't know what additional backdoors exist in encryption algorithms today, but we do know that decrypting information is one of intelligence services' top goals. High-level professionals are continually working on it, and governments are pouring money into it. It is well known that the majority of efforts are focused on cracking SSL protocols, 4G security technologies, and VPNs.

The creation of a file made out of human DNA that is capable of retaining terabytes of information is a very real future for scientists.

To this day, humanity has produced around 10 trillion gigabytes of data, and on a daily basis, people generate emails, photographs, films, and other information that add up to another 2.5 million gigabytes. A significant portion of this information is kept in exabyte data centers, which have the footprint of several football fields and have an annual operating cost of one billion dollars. However, researchers have developed an alternate strategy, which consists of a section of DNA that is able to store vast quantities of information in a compact shape.

According to Mark Bath, a professor of biology at the Massachusetts Institute of Technology, you could hypothetically put all of the data in the world into a coffee cup full of DNA.

The DNA molecule is an ideal storage device for digital data

"We need innovative methods to store the massive volumes of data that are growing throughout the world," says Mark Bath. "DNA is a thousand times denser than any flash drive, and it also has the fascinating virtue of not using energy. Anything may be written into DNA and stored indefinitely " he continues.

Text, images, and any other type of information are all encoded as a series of zeros and ones when saved to digital storage devices. The same information may be encoded in DNA using the four nucleotides that make up the genetic code, which is designated by the letters A, T, G, and C. For instance, the numbers 0 and 1 can be represented by the letters G and C, respectively.

DNA possesses various characteristics that make it a good information carrier:

•  DNA is very stable

•  DNA is relatively simple to synthesize and sequence

•  DNA is highly dense, each nucleotide corresponding to two bits is around 1 cubic nanometer. An exabyte can fit in the palm of your hand.

However, there is a drawback. The expense of producing such enormous amounts of DNA is huge. Recording one petabyte of data (1 million gigabytes) now costs $1 trillion. According to Bath, the cost of synthesis needs to be decreased by around six orders of magnitude before creating archives based on a biological polymer becomes economical. According to the expert, this is entirely feasible in 10-20 years.

Another difficulty is obtaining the needed file.

"What happens if technology advances to the point where it is economically feasible to write an exabyte or zettabyte of data into DNA? You'll have a pile of DNA containing millions of photographs, texts, videos, programs, and other data, and you'll need to locate a certain file: how will you accomplish it?" Bath inquires.

It's like looking for a needle in a haystack.

How are files encoded?

At this time, the PCR is the most common method for obtaining DNA files (polymerase chain reaction). Each file contains a sequence that is designed to bind to a particular PCR primer (a primer is a short piece of nucleic acid). Each primer is introduced to the sample individually in order to locate the necessary sequence in order to extract a particular file. However, one of the drawbacks of using this method is that it increases the likelihood of a phenomenon known as crosstalk occurring between the primer and the DNA sequences, which can lead to the loss of some files. In addition, the synthesis process of PCR calls for enzymes and results in the loss of a considerable amount of DNA. You sort of have to burn a haystack to locate a needle.

The problem was solved by Professor Bath and his colleagues when they encapsulated each file in a silica particle measuring 6 micrometers and included a brief DNA sequence that indicated what was contained within the file. The researchers were able to retrieve individual photos that were saved as DNA sequences from a batch of 20 files by using this method, which resulted in an accuracy rate of one hundred percent. It is conceivable to scale up to a sextillion files given the number of potential labels that may be utilized. By the way, a sextillion is a number that consists of one and 20 zeros following it.

Hack DNA to find the right file

The team at MIT devised a novel extraction approach by isolating each file in a silica particle as an alternate option. Each such "capsule" is labeled with a single string of "barcodes" relating to the file's contents, such as "cat", "airplane", and so on. The researchers encoded 20 distinct pictures into DNA segments around 3,000 nucleotides long, which is comparable to about 100 bytes, to show their method in a cost-effective manner. (They also demonstrated that data as large as a gigabit might fit within the capsules).

When the researchers sought to extract a specific image, they deleted the DNA sample and replaced it with primers that matched the labels they were seeking — "cat", "red", and "wild" for a tiger shot, or "cat", "orange", and "domestic" for a domestic cat photo. The primers are then tagged with fluorescent or magnetic particles, making it simple to extract and identify any files while leaving the remainder of the DNA intact for eventual storage. This strategy is comparable to looking for terms on Google.

"So far, the search speed is one kilobyte per second. The size of the data per capsule determines the search speed of our file system. It is also worth mentioning that the speed is constrained by the prohibitively high cost of writing even 100 gigabytes of data per DNA, as well as the number of sorters that may be used concurrently.

"If DNA synthesis gets cheap enough, we can optimize the quantity of data stored", said scientist James Banal.

The researchers created their barcodes using single-stranded DNA sequences from a library of 100,000 sequences, each around 25 nucleotides long, established by Stephen Elledge, a genetics and medicine professor at Harvard Medical School. If you place two of these labels on each file, you may label each one uniquely.

Final words

While DNA may not be extensively employed as a data carrier for some time, there is currently a large need for low-cost, high-volume storage solutions.

The DNA encapsulation approach can be effective for archiving data that is only sometimes accessed. As a result, Professor Bath's laboratory is already hard at work on the formation of a business called Cache DNA, which will provide a method for the long-term storage of information in DNA.

The most frequently-used password globally is "123456”. However, analyzing passwords by country can yield some quite fascinating results.

We frequently choose weak passwords such as "123456" since they are easy to remember and input. The differences between such passwords can sometimes be found in the language itself. For example, if the English have "password" at the top of their list, the Germans prefer "passwort", and the French use "azerty" instead of "qwerty" due to the peculiarities of the French keyboard layout, which has the letter A instead of the usual Q.

When a weak password is driven by culture, things get much more intriguing. The password "Juventus" is likely to appeal to fans of the Italian football team Juventus. This password is also the fourth most popular option among Italian Internet users. The club is from Turin, Piedmont, and is supported by about 9 million people. At first look, the unique password "Anathema" appears to be a typical occurrence in Turkey, where the British band Anathema's name is among the top ten most common passwords.

A weak password is widespread

ExpressVPN together with Pollfish interviewed 1,000 customers about their password preferences in order to learn more about how individuals approach password formation.

Here are some of their findings:

•  The typical internet-goer uses the same password for six different websites and/or platforms

•  Relatives are likely to be able to guess their passwords from internet accounts, according to 43% of respondents

•  When generating passwords, two out of every five people utilize different variants of their first and/or last name

These findings demonstrate a lack of cybersecurity knowledge, despite the fact that 81% of respondents feel confident in the security and privacy of their existing passwords.

According to the survey results, passwords frequently contain personal information. Below, you will find the most shared personal information with the percentage of respondents who revealed that their passwords contained personal information.

•  First Name (42.3%)

•  Surname (40%)

•  Middle Name (31.6%)

•  Date of birth (43.9%)

•  Social security number (30.3%)

•  Phone number (32.2%)

•  Pet name (43.8%)

•  Child's name (37.5%)

•  Ex-partner's name (26.1%)

The most common passwords in various countries

Based on an infographic from ExpressVPN, the picture below illustrates the most often used passwords in various nations, practically all of which are in the top ten in their respective countries. Many are exclusive to these nations and demonstrate how cultural influences impact password creation.

Much of the information presented comes from a third-party study of stolen credentials (which were made public by Github user Ata Hakç). These datasets are based on the language of the individual sites, allowing the information to be distributed by country.

Let's have a look at some interesting variations of passwords. For instance, the phrase "I love you forever" may be deciphered from the password "5201314," which is commonly used by people from Hong Kong. In contrast, users in Croatia make use of the password “Dinamo”, which is derived from the name of an illustrious football team based in Zagreb. Martin is the password that is used by people from Slovakia. In Slovakia, the name Martin has a position as the fourth most common name. The Greeks, on the other hand, chose not to put undue effort into themselves and instead went with the most straightforward password out of the list, which was 212121. On the other hand, Ukrainians use the pretty difficult password Pov1mLy727. Apart from Ukraine, there are other countries where users more often than not create strong passwords. Let’s take a look.

These 10 countries create the strongest passwords

According to the results of the National Privacy Test that was carried out by NordVPN, the greatest marks were obtained by Italians in regard to their understanding of robust passwords. The following is a list of the top ten nations in which people come up with the most complicated passwords.

1. Italy 94.3 (points out of 100)

2. Switzerland 94

3. Spain 93.5

4. Germany 93.3

5. France 92.3

6. Denmark 91.8

7. UK 90.7

8. Belgium 90.4

9. Canada 89.4

10. USA 89.3

The top 10 did not include Australia (88.9), South Africa (86.2), Saudi Arabia (85.7), Russia (81.4), Brazil (81.2), Turkey (73.9), and India (78.4).

"This study demonstrates that individuals from all around the world are aware of how to generate secure passwords. The information is there, but people aren't using it in the right ways," says Chad Hammond, a security specialist at NordPass.

Also in November 2022, NordPass published a study that found out which passwords network users use most often. According to the findings of the survey, the majority of individuals still rely on simple passwords such as their own names, the names of their favorite sports teams or foods, simple numerical combinations, and other straightforward options.

NordPass security specialist Chad Hammond also stated, "Using unique passwords is really crucial, and it's scary that so many individuals still don't." It is critical to generate distinct passwords for each account. "We put all accounts with the same password in danger when we reuse passwords: in the case of a data breach, one account at risk can compromise the others."To summarize, it is reasonable to state that it does not matter where you were born, where you live, or what you are passionate about; you must always use unique passwords. We recommend that you make your password difficult to guess by making it more complicated or by using a password generator. This will increase the level of security provided by your password. In addition to this, we strongly suggest that you take advantage of two-factor authentication wherever it is an option. If you add an additional layer of protection to your accounts, be it in the form of an app, biometrics, or a physical security key, you will notice a significant increase in their level of security.

The truth is, the answer isn’t as straightforward as you might think. A ‘hacker’ is a name that can be ascribed to many different types of individuals — from North Korean crypto bridge drainers to a jealous 16-year-old trying to get into his girlfriend’s Facebook account. That’s why it’s important to understand exactly what a ‘real’ hacker is and what kinds of assaults may be carried out.

As a result of the controversy that surrounds the concept of hacking, hackers frequently get labeled as criminals. The process of obtaining and providing information or data is known as "hacking," and while there are numerous and less severe forms of hacking, "security hacking" is the most common type of hacking. Hacking is, in fact, an interesting component of computer operations that involves obtaining and presenting certain information or data.

The definition "individuals who utilize their knowledge or competence in computer operations to obtain access to systems or defeat Internet security barriers" describes the sort of hacking that falls under this category. "Gaining access" is the fundamental aspect of hacking. Some hackers do it for the thrill of it, while others do it for financial benefit. Some are even driven by political motivations.

Types of security hackers

Black Hat

The average hacker in the headlines and the greatest threat to your company is motivated by monetary gain. Their purpose is to enter your company and steal bank information, private data, and money. The stolen resources are utilized for extortion, illicit market sales, or personal benefit.

White Hat

These hackers are the antithesis of "black hat hackers," since they want to assist companies and support them in their cyber protection efforts either pro bono or in exchange for payment. A firm or an individual that assists with the protection of your organization — in other words. Cyberkite is analogous to a hacker who wears a white hat; they defend the data of your company.

Gray Hat

Personal pleasure drives these hackers. They are aware of everything that white and black hackers are aware of, and they are uninterested in attacking or safeguarding you. Usually, they merely have a good time breaking down fortifications for a test. They seldom do anything damaging, so they cut and go on. They constitute the vast majority of all hackers.

Blue Hat

This hacker is spiteful and hostile. They don't exist unless you make them. As a result, it is worthwhile to follow business ethics and treat consumers and other parties fairly. Because who knows, if you're not playing fair, you enrage them, and one of them turns into a hacker with a blue hat. They frequently modify off-the-shelf attack programs to suit their needs. They then utilize this code to exact vengeance on a company or individual.

Red Hat

Crusaders in cyberspace. They are vigilante superheroes who also serve as judges, juries, and executioners. Their mission is to eradicate black hat hackers from the internet. They employ a slew of black-hat cyberweapons against them. However, you are unaware of their existence since they resemble well-known comic book superheroes. The upside to your business is that they, like white hat hackers, try to defend you.

Green Hat

Inexperienced hackers. They are yet to become full-fledged hackers. They put programming to the test in order to learn. They normally do not assault businesses and instead learn from experienced hackers in internet groups. They don’t usually pose a hazard to your business.

Script Kiddie  

These guys are not like the rest. Of course, they sound like harmless hackers, but their purpose is to cause as much devastation and destruction as possible. They have no desire to steal. They concentrate on scripting and coding but do not create their own software. DoS (denial of service) or DDoS (distributed denial of service) attacks are widespread on their side. As a result, they’ll utilize any sort of assault that might create havoc within your firm, harm your reputation, or result in client loss.

The country with the highest number of hackers

With definitions out of the way, you can be sure of the kinds of hackers we’re talking about. Indeed, China is home to the world's highest number of hackers per capita. It is possible to fall into the trap of believing that everything is predicated just on the size of China's population, which is enormous. However, not everything is as it seems at first glance. The hacker networks or organizations that China employs are among the most advanced and sophisticated in the world. The People's Liberation Army of China (PLAC) backs some of these groups financially and logistically.

Also, in order to achieve domination over other nations in cyberspace, China is encouraging cybersecurity as a culture. This will ensure that its educated youth have an excellent level of cyber literacy. This has also resulted in a rise in the amount of cybercrime. Various estimates suggest that China is responsible for 41% of all cyber assaults that occur throughout the world.

The idea of "network warfare" in Chinese information operations and information warfare is approximately equivalent to the American concept of cyber warfare. According to Foreign Policy magazine, China's "hacker army" numbers between 50,000 and 100,000 members, in addition to other groups and individuals. Chinese hackers might be described as "patient dreamers and social engineers." Asia, the Pacific, and Australia are their favorite locations.

Chinese hackers' typical attacks

A common Chinese hack employs a viral SMS message including a link to gather or install keystroke monitoring software in search of bank account access. It is worth noting that the majority of China's cybercrime infrastructure is based outside the nation, owing to strict government rules. Another factor to consider is that, over the last 20 years, China has swiftly absorbed and overtaken Western nations in the latest technology — for example, the city of Shenzhen is regarded as the world's electronics capital. Furthermore, China's objective cannot be dismissed as a desire to acquire the intellectual property for use in both the business and public sectors. The other is the urge to spy on one's own citizens and those of other nations — yeah, that's right, the surveillance program includes, for example, eavesdropping on Americans online, according to an April 2021 Human Rights Watch report. Will the government take a more active role in combating and preventing cybercrime? Only time will tell.

In contrast to other forms of verification, such as passwords or tokens, biometric authentication relies on an individual's distinct biological traits to confirm their identity. Indeed, it’s harder to fake and is typically more user-friendly since users do not have to memorize passwords or carry about a physical token that may easily be lost or stolen. Additionally, it is more difficult to counterfeit. An essential component of identification is the authenticator.

Analysis of a person's speech may be used for identity verification using a process known as voice recognition, which is sometimes referred to as speech recognition or voice authentication. Airways and soft tissue cavities, in addition to the shape of the mouth and the movement of the jaw, all have an effect on speech patterns and help create a person's distinctive "vocal print."

There’s a kind of speech recognition technology available known as speaker recognition. It’s not the same as voice recognition, which is a technique that is utilized in applications that convert speech to text and in virtual assistants such as Siri and Alexa. Although speech recognition can comprehend spoken words, it cannot verify a speaker's identity based on the speaker's vocal characteristics; however, voice biometrics can.

Methods for recognizing the speaker

There are primarily two methods that may be used for voice authentication:

• Text independent
  Any spoken passphrase or other types of speech material may be used to achieve voice authentication
• Text-dependent
  In both the registration process and the verification process, you will use identical passphrases. This implies that the speaker will be asked to repeat a sentence that has already been decided upon, rather than being allowed to say anything that they would want to affirm. When using static text voice authentication, the password that is used for one verification is utilized for all of the verifications. The user is provided with a passphrase that is completely random, such as a series of numbers, through dynamic text-based voice authentication. Additionally, registration is required for this content.

Registration and confirmation of identity

It is necessary to capture the biometric speech sample and then register it with the microphone in order to generate a reference template that can be used for comparison with samples during subsequent authentication attempts. After that, distinctive aspects of the vocal performance are observed, such as:

• Duration
• Intensity
• Dynamics
• Innings

Examples of voice authentication

The hands-free mobile authentication use case is the most common use for voice authentication. This kind of identification is perfect for use on mobile phones or in other situations where other types of biometric verification, such as face recognition, fingerprint recognition, or iris recognition, are impractical. in automobiles.

Voice authentication may also be beneficial for voice recognition devices like Amazon Alexa and Google Home. There has been a recent uptick in the usage of virtual assistants to carry out activities such as placing orders and doing other tasks that would traditionally demand some kind of verification.

During help desk conversations, speaker recognition may also serve as an authenticator for callers. When compared to supplying personal information to verify identification, such as a driver's license or credit card number, users may discover that this method is not only more secure but also more convenient.

Advantages of voice recognition

Low operational costs

Voice authentication may result in cost savings for call centers as well as financial institutions. They are able to save millions of dollars because of the fact that this technology does away with many of the stages required by conventional verification procedures. During an end-to-end conversation, it is able to validate the customer's identification just by recognizing their voice, eliminating the need for the routine questions that are often asked.

Improved quality of life for the end customer

Voice biometric systems provide a number of benefits, one of which is that they have the potential to significantly enhance the customer experience. However, this potential is sometimes overlooked. It is no longer necessary for callers to provide passcodes, PINs, or answers to challenge questions in order to have their identities verified.

Because of this, speech biometrics are ideal for omnichannel and multichannel deployments. Once a client has been registered, their voiceprint may be utilized across all of a company's support channels, making speech biometrics suitable for omnichannel and multichannel deployments.

Increased accuracy

Voice authentication is more reliable and accurate than using passwords, which are simple to forget, change, or guess. Passwords are also easier to compromise. It's kind of like how fingerprints are the only thing that can identify you. To put it another way, in contrast to passwords, a voice is impossible to forget or imitate. In spite of the fact that the sound might be influenced by a number of factors, it is much more dependable and handy.

Technology that is simple to put into action

The ease of use and implementation that speech recognition biometrics provide is very valuable to a lot of different companies. It may be difficult to implement some forms of biometric technology inside an organization and to get started with these systems. However, due to the fact that speech biometric systems need so little, it is often possible to install them without the need for extra hardware or software.

Because this technology is so easy to use, businesses often have the ability to redeploy employees to other areas of the organization in order to improve both their efficiency and the level of pleasure they provide to their customers.

Conclusion

Voice authentication is an excellent method for verifying a user's identity since it offers extra levels of security, which manual passcodes may not be able to give. Voice authentication is a wonderful approach to verifying a user's identity. Voice authentication is advantageous for both the company and its consumers since it eliminates the annoyance that is associated with laborious login procedures.

There is no good reason, from a technical standpoint, why passwords can't contain scripts in Chinese, Japanese, Korean, or any other language for that matter. If you are able to write in this script, then it is entirely appropriate for you to employ it in whatever endeavors you undertake.

However, if you put this theory to the test, you will discover that many websites, including well-known ones like Google, prevent you from entering a password that contains characters other than A-Z, 0-9, and common special characters.

This brings to mind the early days of the internet when certain websites forbade the use of capitalization and prohibited the use of Latin letters for no discernible reason.

Site issues with passwords including Chinese characters

Users often make use of passwords that are longer than 30 characters, include all of the various character kinds that are usually suggested, and are created at random. If you use a password manager, you should probably make the password as difficult and as lengthy as it can possibly be.

However, if you visit more than 150 websites and change your password each time, you may find that many websites have password rules that do nothing but lower their level of security rather than increase it. This is because these rules are designed to protect users from themselves.

For instance, several websites impose arbitrary restrictions on the maximum length of passwords. They will typically demand passwords with less than 20 characters, in many instances. In certain cases, you can only use a maximum of 12 characters.

Even though it makes the password less secure, certain websites require that you include a number and a special character. This is despite the fact that doing so decreases the entropy of the password. On other pages, one may be restricted to using just the Latin letters; numerals and punctuation are not allowed. On certain websites, one may use punctuation, but you have to choose it from a drop-down menu first, and characters like "&" are not permitted.

This last point ought to give you significant cause for worry. Are these websites capable of sanitizing the password before inserting it into the database? Your database should not be used to store passwords in any way. I'm curious how many times this has been the cause when we consider severe breaches of privacy. You are required to hash the password before saving it.

In any event, the end effect of all of this is that a significant number of websites still verify passwords in an erroneous manner, excluding characters that really should be fully allowed. There is no valid reason why "您未设置安保问题" can’t serve as your password.

So, how safe is such a password?

Entropy is a term used to describe both the difficulty of breaking a password and the complexity of the password itself. In the next paragraphs, we will examine how to compute the entropy of a password.

If we expand the character set to cover everything from a to Z, digits from 0 to 9, punctuation marks, and so on, then we have a pool of 90 characters. This results in an entropy per character of log2(90), which is equivalent to 6.49 bits. If, on the other hand, we expand our character pool to include all Chinese, Japanese, and Korean (CJK) characters (presuming that our character pool has 74,605 characters), then we can calculate the entropy of each character as log2 (74605) = 16.19 bits of entropy per character.

Therefore, a 7-character CJK password such as "正确的马电池钉" would give you 16.19 bits of entropy times 7, which equals 113.33 bits total. I would need a password consisting of 18 characters if I wanted to match this using Latin letters, numbers, and special characters.

The vast majority of people are Chinese-illiterate. They have decided against using any characters that include CJK in their passwords. On the other hand, the effectiveness of a complicated password is comparable to that of vaccination in that it confers herd immunity. Crackers will only conduct brute force or dictionary attacks based on the letter az if individuals only use passwords that include those letters. If people have a habit of using numbers and punctuation, it forces attackers to incorporate those elements into their vocabulary, which in turn slows down their attack. The attacker needs to try all of these additional possible combinations, regardless of whether or not your own password used any of them.

Because roughly one-third of the world's population is able to read and write CJK characters (the populations of China and Japan are enormous), if we permit people to use CJK characters in their passwords, then even if I don't use CJK characters myself, we can all benefit from the increased complexity that this provides.

To reiterate, knowledge of Chinese is not required in order to work with CJK characters. You can keep track of all of your passwords by using a password manager, as was previously suggested. It does not matter whether you are unable to read or write the password as long as the password manager is able to save it and accurately copy and paste it into the password box when it is required.

Conclusion

We’d like to remind everyone that your name, birth date, or any other identifying information should never be used as a password, regardless of the language you use.

In addition, the passwords that are established on other websites might somewhat vary from one another, which makes them easier to remember and prevents the same issue from occurring. In this scenario, it is essential to connect your mobile phone number or email address so that you may easily recover the account in the event that the mobile phone number is lost or stolen.

On the other hand, many people feel that passwords are becoming outdated and that there are now more efficient methods to handle computer security and authentication than by using passwords. Perhaps now is the moment for people to begin shifting their attention to other approaches. In the not-too-distant future, we will find out.

In the new version of Passwork, we have completely redesigned the System settings. They are now divided into three sections:

1. Global — organization settings that determine the operations of most of the Passwork functions
2. Default — the values of the settings that will be used if no other custom settings are specified
3. Custom — settings that can be set for individual users and roles

Now you can set up different interface languages, configure authorization methods, and enable mandatory two-factor authentication for individual users and roles.

To do this, click "Create a new settings group" in Сustom settings, add users or roles and select your desired settings. The newly created group will be added to the top of the list and will get the highest priority.

The following settings are now available:

• Ability to create organization vaults and private vaults
• Ability to create links to passwords
• Mandatory 2FA
• Time of automatic logout when inactive
• Authorization method (by local password, LDAP password or SSO)
• API usage
• Interface language

We're already working to add new settings.

Multi-factor authentication (often known as MFA for short), refers to the process of confirming the identity of a user who is attempting to log in to a website, application, or another type of resource using more than one piece of information. Indeed, multi-factor authentication is the difference between entering a password to gain access to a resource and entering a password plus a one-time password (OTP), or a password plus the answer to a security question. Another example of multi-factor authentication is entering a password plus the answer to a security question.

Multi-factor authentication provides greater assurance that individuals are who they claim to be by requiring them to confirm their identity in more than one way. This, in turn, reduces the risk of unauthorised access to sensitive data. Multi-factor authentication requires individuals to confirm their identity in more than one way. After all, entering a stolen password to get access is one thing; it is quite another to enter a stolen password and then be needed to additionally input an OTP that was sent to the smartphone of the real user.

Multi-factor authentication can be achieved through the use of any combination of two or more factors. Two-factor authentication is another name for the practice of using only two factors to verify a user's identity.

How Does MFA work?

MFA is effective because it necessitates the collection of extra verification information (factors). One-time passwords are one of the multi-factor authentication mechanisms that consumers encounter most frequently (OTP). OTPs are the four-digit to eight-digit codes that you frequently receive through email, SMS, or a mobile application of some kind. When using OTPs, a fresh code will be created at predetermined intervals or whenever an authentication request is sent in. The code is created based on a seed value that is assigned to the user when they first register and some other component, which might simply be a counter that is incremented or a time value. This seed value is used in conjunction with some other factor to generate the code.

The three categories of multi-factor authentication methods

Generally speaking, a technique of multi-factor authentication will fall into one of these three categories:

•  Something you are familiar with: a PIN, password, or the solution to a security question

•  Something you own: an OTP, a token, a trusted device, a smart card, or a badge

•  Something you are, such as your face, fingerprint, retinal scan, or other biometric information

Methods of multi-factor authentication

In order to accomplish multi-factor authentication, you will need to utilise at least one of the following methods in addition to a password.

Biometrics

A method of verification that depends on a piece of hardware or software being able to recognize biometric data, such as a person's fingerprint, facial characteristics, or the retina or iris of their eye.

Push to approve

A notice is shown on someone's smartphone that prompts the user to tap their screen in order to accept or deny a request for access to their device.

One-time password (OTP)

A collection of characters that are created automatically and are used to authenticate a user for a single login session or transaction only.

An SMS

A method for sending a One-Time Password (OTP) to the user's smartphone or other devices.

Hardware token

A compact, portable OTP-generating device that is sometimes referred to as a key fob.

Software token

A token that does not exist in the form of a physical token but rather as a software program that can be downloaded onto a smartphone or other device.

The advantages of multi-factor authentication

Enhancing the level of safety

Authentication that takes into account many factors is more secure. After all, when there is only one mechanism defending a point of access, such as a password, all a malicious actor needs to do to get admission is figure out a means to guess or steal that password. This is the only thing that needs to be done in order to acquire access. However, if admittance additionally needs a second (or perhaps a second and a third) element of authentication, then it becomes far more difficult to obtain access, particularly if the requirement is for something that is more difficult to guess or steal, such as a biometric characteristic.

Providing support for various digital initiatives

Multi-factor authentication is a key enabler in today's business world, where more companies are keen to deploy remote workforces, more customers want to purchase online rather than in shops, and more companies are migrating apps and other resources to the cloud. In this day and age, it can be difficult to ensure the safety of organisational and e-commerce resources. Multi-factor authentication can be an extremely useful tool for assisting in the protection of online interactions and financial transactions.

Are there any disadvantages to multi-factor authentication?

It is feasible to establish a less easy-to-access environment while building a more secure one — and this might be a disadvantage (this is especially true as zero trust, which sees everything as a possible threat, including the network and any apps or services running on it, gains acceptance as a safe access basis). No employee wants to spend additional time each day dealing with several impediments to getting on and accessing resources, and no consumer wants to be slowed down by multiple authentication procedures. The objective is to strike a balance between security and convenience so that access is secure but not so onerous that it causes excessive hardship for those who legitimately require it.

The role of risk-based authentication in multi-factor authentication

One technique to achieve a balance between security and convenience is to increase or decrease authentication requirements based on the risk associated with an access request. This is what risk-based authentication entails. The risk might be associated with either what is being accessed or who is requesting access.

The risk presented by what is accessed

For example, if someone seeks digital access to a bank account, is it to initiate a money transfer or simply to verify the status of an existing transfer? Or, if someone interacts with an online shopping website or app, is it to place an order or to monitor the progress of an existing purchase? For the latter, a username and password may be sufficient, but multi-factor authentication makes sense when a high-value item is at stake.

The risk is presented by the person requesting access

When a remote employee or contractor seeks access to the corporate network from the same city, on the same laptop, day after day, there's little reason to assume it's not that person. But what happens when a request from Mary in Minneapolis arrives from Moscow unexpectedly one morning? A request for extra authentication is warranted due to the possible danger – is it really her?

The future of Multi-Factor Authentication: AI, Machine Learning and more

Multi-factor authentication is always improving to provide enterprises with access that is both more secure and less unpleasant for individuals. Biometrics is an excellent example of this concept. It's more secure, since stealing a fingerprint or a face is difficult, and it's more convenient because the user doesn't have to remember anything (such as a password) or make any other substantial effort. The following are some of the current advancements in multi-factor authentication.

Machine learning (ML) and artificial intelligence (AI)

AI and ML may be used to identify characteristics that indicate if a particular access request is "normal" and as such, does not require extra authentication (or, conversely, to recognize anomalous behaviour that does warrant it).

Online Quick Identity (FIDO)

The FIDO Alliance's free and open standards serve as the foundation for FIDO authentication. It facilitates the replacement of password logins with safe and quick login experiences across websites and applications.

Authentication without a password

Rather than utilising a password as the primary means of identity verification and complementing it with alternative non-password methods, passwordless authentication does away with passwords entirely.

Be certain that multi-factor authentication will continue to evolve and develop in the pursuit of methods for individuals to show they are who they say they are — reliably and without having to jump through an endless number of hoops.

It's possible that you've become familiar with the term "time-based one-time passwords" (TOTP) in relation to "two-factor authentication" (FA) or "multi-factor authentication" (MFA).

However, do you really understand TOTP and how they work?

The Meaning of TOTP

"Time-Based One-Time Passwords” refer to passwords that are only valid for 30-90 seconds after they have been formed with a shared secret value and the current time on the system.

Passwords are almost always composed of six-digit sequences that are changed every thirty seconds. On the other hand, some implementations of TOTP make use of four-digit codes that become invalid after a period of 90 seconds.

An open standard is used in the TOTP algorithm, and this standard is detailed in RFC 6238.

What is a shared secret?

TOTP authentication uses a shared secret in the form of a secret key that is shared between the client and the server.

To the naked eye, the Shared Secret seems to be a string with a representation in Base32 that is similar to the following:

KRUGS4ZANFZSAYJAONUGC4TFMQQHGZLDOJSXIIDFPBQW24DMMU======

Computers are able to comprehend and make sense of information even if it is not legible by humans in the manner in which it is presented.

The client and the server both have a copy of the shared secret safely stored on their respective systems after a single transmission of the secret.

If an adversary is able to discover the value of the shared secret, then they will be able to construct their own unique one-time passcodes that are legitimate. Because of this, every implementation of TOTP needs to pay particular attention to securely storing the shared secret in a safe manner.

What is system time?

There is a clock that is integrated into every computer and mobile phone that measures what is referred to as Unix time.

Unix time is measured in terms of the number of seconds that have passed since January 1, 1970, at 00:00:00 UTC.

Unix time appears to be nothing more than a string of numbers:

1643788666

This small number, however, is excellent for the generation of an OTP since the majority of electrical devices using Unix time clocks are sufficiently synced with one another.

Implementations of the TOTP Authentication Protocol

The use of passwords is not recommended. However, you may increase security by combining a traditional password with a time-sensitive one-time password (TOTP). This combination is known as two-factor authentication or 2FA, and it may be used to authenticate your accounts, virtual private networks (VPNs), and apps securely.

TOTP can be implemented in hardware and software tokens:

•  The TOTP hardware token is a physical keychain that displays the current code on a small screen

•  The TOTP soft token is a mobile application that displays a code on a phone’s screen

It makes no difference whether you use software tokens or hardware tokens. The purpose of using two different forms of authentication is to increase the level of protection afforded to your online accounts. You have access to a one-time password generator that you may use during two-factor authentication to obtain access to your account. This generator is available to you regardless of whether you have a key fob or a smartphone with an authentication app.

How does a time-based one-time password work?

The value of the shared secret is included in the generation of each time-based one-time password (TOTP), which is dependent on the current time.

To produce a one-time password, the TOTP method takes into account both the current Unix time and the shared secret value.

The counter in the HMAC-based one-time password (HOTP) method is swapped out for the value of the current time in the time-based one-time password algorithm, which is a version of the HOTP algorithm.

The one-time password (TOTP) technique is based on a hash function that, given an input of indeterminate length, generates a short character string of fixed length. This explanation avoids getting too bogged down in technical language. If you simply have the result of a hash function, you will not be able to recreate the original parameters that were used to generate it. This is one of the hash function's strengths.

It is essential to keep in mind that TOTP offers a higher level of security than HOTP. Every 30 seconds, a brand new password is produced while using TOTP. When using HOTP, a new password is not created until after the previous one has been entered and used. The fact that the one-time password for HOTP continues to work even after it has been used for authentication leaves hackers with a significant window of opportunity to mount a successful assault.

Authentication using Multiple Factors (MFA)

A user must first register their TOTP token in any multi-factor authentication (MFA) system that supports a time-based one-time password before they can use the device to connect to their account.

Some TOTP soft tokens need the registration of a different OTP generator for each account. This effectively implies that if you add two accounts to your authenticator app, the program will produce two temporary passwords, one for each account, every 30 seconds. A single TOTP soft token (authenticator program) may support an infinite number of one-time password generators. Individual one-time password generators safeguard the security of all other accounts in the case where the security of an account is compromised.

To use 2FA, a secret must be created and shared between the TOTP token and the security system. The security system's secret must then be passed to the token.

How is the shared secret sent to the token?

Typically, the security system creates a QR code and requests that the user scan it using an authenticator app.

A QR code of this type is a visual depiction of a lengthy string of letters. The shared secret is, roughly speaking, part of this lengthy sequence.

The software will string the image and extract the secret when the user scans the QR code using the authenticator app. The authenticator program may now utilize the shared secret to generate one-time passwords.

When registering a TOTP token, the secret is only sent once. Many of the concerns about stealing the private key are alleviated. An adversary can still steal the secret, but they must first physically steal the token.

It works even when you're not connected to the internet!

To use the TOTP technique, you do not need an active internet connection on your smartphone or a physical key.

The TOTP token only needs to obtain the shared secret value once. The security system and the OTP generator may thus produce successive password values without needing to communicate. As a consequence, time-based one-time passwords (TOTP) operate even when the computer is turned off.

Facial recognition is a technology-based method of identifying a human face. Such a recognition system maps facial characteristics from an image or video using biometrics. To identify a match, it compares the information gained to a database of known faces. Facial recognition may aid in the verification of a person's identification, but it also presents privacy concerns.

The facial recognition industry is predicted to expand from $4 billion in 2017 to $7.7 billion in 2022. This is due to the fact that such technology holds several business uses including monitoring and marketing.

But here's where things become difficult. If you value your privacy, you undoubtedly want some say over how your personal information (your data) is utilised. The truth is, your "faceprint" is your personal information.

How does facial recognition work?

You might be adept at identifying people's faces. You probably have no trouble recognizing the face of a family member, friend, or acquaintance. You recognize their facial characteristics — their eyes, nose, and mouth and their facial movements.

That is exactly how a face recognition system operates but on a much larger, computational scale. Recognition technology sees data where you see a face. That information may be saved and retrieved. According to Georgetown University research, half of all American adults have their photos recorded in one or more facial-recognition databases that law enforcement authorities may consult should they wish to.

So, how does facial recognition really work? Although certain technologies differ, most follow a standard procedure:

•  A photograph or video of your face is obtained. Your face might be scanned alone or in a crowd. Your photo might show you gazing straight ahead or almost in a profile view.

•  The geometry of your face is scanned by facial recognition software. The distance between your eyes and the distance from your forehead to your chin are important considerations. The program recognizes facial landmarks — one system even recognizes 68 of them – which are all important in differentiating your face. As a consequence, your facial signature is created.

•  A database of known faces is matched to your facial signature, which is a mathematical formula. Consider the following: At least 117 million people in the United States have photos of their faces in one or more police databases. The FBI has access to 412 million of such pictures for searches, according to a May 2018 report.

•  A decision is made. Your faceprint could match one in a database bringing back a positive result.

How effective is facial recognition?

Experts are concerned that face recognition might result in incorrect identifications. What if a police agency wrongly identifies someone smashing a shop window during a riot as someone who was nowhere near the incident using facial recognition technology? How probable is it that such an incident will occur?

It depends. According to the National Institute of Standards and Technology tests, the top face recognition algorithm has an error rate of under 0.08% as of April 2020. This is a significant improvement from 2014 when the best algorithm on the market had an error rate of 4.1%.

According to a 2020 report by the Centre for Strategic & International Studies (CSI), accuracy is greater when identification algorithms are used to match persons to clear, static photos, such as passport photos and mugshots. When applied in this manner, face recognition algorithms achieved up to 99.97% accuracy on the National Institute of Standards and Technology's Facial Recognition Vendor Test.

In practice, however, accuracy rates are often lower. According to the CSI report, the Facial Recognition Vendor Test discovered that the mistake rate for one algorithm increased from 0.1% when faces were matched to high-quality mugshots to 9.3% when faces were matched against images of people caught in public. When individuals were not looking straight at the camera or were partly concealed by shadows or objects, error rates increased.

Another issue is ageing. According to the Facial Recognition Vendor Test, middle-tier facial recognition algorithms exhibited mistake rates that increased by roughly a factor of ten when attempting to match photographs of participants shot 18 years earlier.

Who employs facial recognition?

Many individuals and organisations utilise face recognition in a variety of settings. Here are a few examples:

Airport administration

In airports, facial recognition technologies can monitor persons entering and exiting. The technology has been utilised by the Department of Homeland Security to identify persons who have overstayed their visas or are under criminal investigation.

Product manufacturers of mobile phones

Apple originally employed facial recognition to unlock the iPhone X, and since, the technology has been carried over to all subsequent models. Face ID authenticates — it ensures that you are who you say you are when you access your phone. According to Apple, the likelihood of a random face unlocking your phone is one in one million.

Websites for social networking businesses

When you post a picture to Facebook, an algorithm is used to detect faces. If you wish to tag others in your images, the social media firm will ask you. If you answer yes, a connection to their profiles is created. Facial recognition on Facebook is 98 percent accurate.

Entrance businesses and restricted zones

Some businesses have abandoned security badges in favour of facial recognition technologies.

Religious congregations at places of worship

Face recognition has been used by churches to scan their congregations to see who is there. It's a fantastic method to keep track of regulars and irregulars, as well as to adapt contribution requests.

Campaign marketers and advertisers

When targeting groups for a product or concept, marketers often consider factors such as gender, age, and ethnicity. Even during a performance, facial recognition may be used to determine such audiences.

The use of facial recognition in police enforcement

Today, facial recognition databases play an important role in law enforcement. According to an Electronic Frontier Foundation investigation, law enforcement agencies frequently collect mugshots from jailed people and compare them to local, state, and federal face recognition databases.

Law enforcement organisations may use these mugshot databases to identify persons in images collected from a number of sources, including closed-circuit television cameras, traffic cameras, social media, and photos taken by police officers themselves.

According to the Electronic Frontier Foundation, police officers may also use their mobile phones, tablets, or other devices to take images of cars or pedestrians and instantaneously match their photos to the faces in one or more facial recognition databases.

In addition, police enforcement has utilised face recognition to identify persons who may be sought in connection with crimes at huge events such as concerts, sports events, or the Olympics.

Several face recognition technologies are available to the federal authorities. Its primary database, however, is the FBI's Next Generation Identification system. This collection comprises over 30 million images.

Conclusion

Opponents of face recognition systems argue that although they give some protection, it is not enough to outweigh a feeling of independence and freedom. Many people believe that the usage of these technologies violates their privacy, but their worries don't stop there. They also emphasise the dangers of identity theft. Even face recognition companies recognize that as the technology becomes more widely used, the probability of identity theft or fraud increases.

As with many emerging technologies, the enormous promise of facial recognition has its downsides, but manufacturers are working to improve the usability and accuracy of their systems every day.

Over the last several years, Chinese smartphones have gained a very lousy reputation when it comes to privacy, owing to a variety of factors including a lack of customer trust and the fact that global political events have not been particularly kind to China. China's worldwide image improved significantly in the mid-2010s, owing mostly to China's entry into the smartphone market and developments in 4G and 5G technology.

The market for smartphones is now one of the most rapidly developing areas of the technology sector worldwide. The number of mobile devices sold around the globe has skyrocketed from 100 million in 2007 to over 1.5 billion, which saw the advent of the smartphone revolution. Because smartphones are the most frequent way of connecting to the internet, companies that operate in this sector are vital to the development of the technology sector.

We saw the original Apple iPhone debut 14 years ago in 2007, which surely signaled the beginning of a new era of information. We've seen huge players like Samsung join the market throughout the years, and more lately, Chinese competitors like Huawei and Xiaomi have been eating up worldwide market share with their low-cost handsets. Moreover, Oppo and Vivo, which have a tiny but consistent market share and are even gaining popularity in the United States, should not be overlooked.

Apple has never been as successful in China as it is elsewhere, owing to the country's preference for domestic produce and local brand loyalty. Having said that, Apple has always been in demand there. Outside of China, however, Apple has controlled the smartphone industry for a long time, and the whole globe often lies in anticipation of their next news conference and the release of their next iPhone. For many years, market supremacy was exchanged between Apple and Samsung, with Samsung ruling the majority of the time.

However, the worldwide smartphone market has shifted recently. With such strong competition (Samsung, Xiaomi, Huawei) on the horizon, as well as Apple's extremely expensive pricing for its current products, Chinese competitors have adapted and established a stable market hold for the foreseeable future. Chinese smartphone manufacturers are now a serious rival for the established giants, offering the similar minimalist design approaches that Apple is renowned for, as well as entirely redesigning their marketing efforts. Finally, the US and EU markets are the most significant target markets for Chinese smartphones.

However, there seem to be severe privacy concerns that are impeding Chinese smartphones and their image.

What is the issue with Chinese smartphones?

There are a number of Chinese companies that are now producing smartphones on the market, with Huawei and Xiaomi being the most well-known and popular brands in countries other than China. The majority of customers may not be acquainted with some of the other "cheaper" businesses, such as Honor and Realme. There are a great number of other Chinese smartphone manufacturers, perhaps too many to list here.

What difference does it make whether you want to buy a Chinese smartphone or if you already own one, given the amount of political tension that exists between the United States and China? Unhappily, Chinese smartphones have been afflicted with a number of privacy and security issues, which may be broken down into the following categories:

•  Spyware already installed

•  Vulnerabilities when it comes to malware

•  Data theft

•  "Backdoors" in Hardware

•  Encryption-related flaws

Moreover, there are extra hazards involved with downloading particularly popular Chinese social networking applications, in addition to the malware that comes pre-installed on Chinese devices. Some examples of these risks include:

•  TikTok

•  WeChat

Conclusions for your smartphone's overall security

Let's not forget, now that we've covered the reasons why there is such a lot of bad buzz about Chinese smartphones and the privacy issues they pose, that a large part of this has to do with the political tensions that exist between China and the United States. Allegations of espionage, hacking, and danger to data have been made an extremely high number of times. In addition to that, there is an additional fact that is more significant for the typical user. Android, which has a far bigger user population and is thus more vulnerable to assaults because of the size of its user base, is the foundation upon which Chinese phones are built.

Let us highlight one thing: certainly, it is difficult to declare that these technologies are safe; but, the question is: what really is safe in this day and age? Should this make you, the regular person, think twice about purchasing a smartphone made in China? It is difficult to say what constitutes "security" at this time, and whether or not governments will try to gain access to your phone depends heavily on who you are and how sensitive your data is.

However, if you are concerned about your privacy, there are a few steps you should take for your own protection and peace of mind, regardless of the device you are using or the nation in which it was manufactured; the following is a list of these steps, which you may read below:

•  Always utilize a reputable virtual private network (VPN)

•  Consider the possibility that iOS is more secure than Android in general

•  Make sure your phone is protected by a strong password

•  Ensure that multi-factor authentication is used at all times

•  If at all possible, avoid sharing critical information online

•  Keep your smartphone's software up to date at all times

•  Never use suspicious applications or access third-party app marketplaces

Most of web3's security is based on the blockchain’s unique ability to be resistant to human intervention. However, because of the associated feature of finality, where transactions are generally irreversible, these software-driven networks are an attractive target for attackers. Likewise, as the value of blockchains — the distributed computer networks that underpin Web3 — grows, they become increasingly appealing.

While web3 differs from previous web iterations, we have seen similarities with prior software security patterns. In many cases, the most serious issues stay unchanged. Advocates, whether they are builders, security teams, or everyday crypto users, can better secure themselves, their projects, and their wallets by learning these areas. Based on people's experiences, we've compiled a list of recurring themes and predictions.

Chase the money

Typically, attackers seek to maximise their return on investment. Because the potential return is bigger, they may devote more time and effort to attacking protocols with a higher "total value locked," or TVL for short.

Hacking groups with the highest amounts of resources are more likely to target high-value systems. New, more valuable exploits are also more likely to target these important targets.

Low-cost assaults, such as phishing, will never go away, and we expect them to become more prevalent in the near future.

Fixing a hole

As developers learn from tried-and-true assaults, they can improve web3 software to the point where it is "safe by default." This frequently entails tightening up application programming interfaces (APIs) to make it more difficult for people to add vulnerabilities by mistake.

Because security is always a work in progress, and nothing is ever immune to hacking, defenders and developers may make attacks more expensive by removing most of the low-hanging fruit for attackers.

The success of the following attacks may be considerably reduced as security policies and tools improve: control attacks, price oracle manipulation, and re-entry problems.

Platforms that cannot provide "perfect" security will have to employ exploit mitigation methods to decrease the possibility of losses. This can deter attackers by lowering the "benefit" or possible benefit component of their cost-benefit analysis.

Attack classification

Attacks on various systems can be categorised based on their similarities. The sophistication of the attack, the extent to which attacks can be automated, and the preventive measures available to fight against them are all defining aspects.

The following are some of the types of assaults that users have observed in the most recent hacks. We've also included our thoughts on the current threat landscape and what we anticipate from web3 security in the future.

Top predators in APT Operations

Advanced attackers, often known as advanced persistent threats (APTs), are a security nightmare. Their motivations and talents vary significantly, but they are usually well-endowed and, as the term suggests, persistent; unfortunately, they are likely to constantly be present. APTs carry out a wide range of operations, but these threat actors are the most likely to actively assault a company's network layer to achieve their objectives.

We know that certain advanced groups are actively pursuing web3 initiatives, and assume that there are others who have yet to be discovered. The people behind the most serious APTs typically reside in countries with no extradition accords with the US and EU, making it harder to punish them for their actions. Lazarus Group, a North Korean gang responsible for the greatest сryptocurrency heist on record, is one of the most well-known APT attackers.

We anticipate that APTs will continue to operate as long as they can monetize their activities or achieve various political objectives.

Social engineers engage in customer phishing

Phishing is a well-known and prevalent issue. Phishers attempt to trick their victims into falling into a trap by delivering bait messages over numerous channels such as instant messengers, email, Twitter, Telegram, Discord, and compromised websites. If you look through your spam folder, you're sure to find hundreds of efforts to deceive you into disclosing personal information or stealing money.

Phishing efforts are targeting web3 users now that it allows people to directly exchange assets like tokens or NFTs quickly. These assaults are the simplest way for persons with little to no technical knowledge to profit from cryptocurrency theft. They remain, however, a viable technique for organised teams with serious goals or advanced groups looking to undertake large-scale wallet-emptying attacks, such as website hijacking.

We anticipate a rise in these attacks because phishing is inexpensive and phishers seek to adapt to and circumvent the most recent security features. Increased education and awareness, better filtering, clearer warning banners, and tighter wallet restrictions can all help to improve user protection.

Vulnerabilities in the supply chain are the weakest links

Third-party software libraries expose a significant surface for attack. This has long been a security concern for pre-Web3 systems, as evidenced by the log4j hack that compromised a popular web server’s software in December. Attackers will search the Internet for known vulnerabilities in order to locate unpatched flaws to attack.

Although the imported code was not built by your engineering team, it must be maintained. Teams must keep an eye out for vulnerabilities in their software components, ensuring that updates are deployed, while staying up to speed on the dynamics and progress of the projects on which they rely. The real and immediate cost of exploiting web3 software vulnerabilities makes communicating these issues to library users challenging. The decision on how and where the teams communicate this in a way that does not mistakenly jeopardise users' monies is still pending.

We expect Supply Chain Vulnerabilities to rise as the dependency and complexity of software systems grow. Random hacking assaults are expected to rise as well until solid, standardised ways for exposing web 3 security flaws are created.

GPS devices have been made accessible to a wider market as technology advances, and the degree to which our daily lives rely on precise location and timing has also increased. For tourists to navigate effectively from one location to another, the use of a global positioning system (GPS) has become standard.

Businesses and people now have access to possibilities that were previously unavailable because of GPS. On the other hand, this is not always a positive thing since spoofing might make GPS systems susceptible to cyber assaults. Let's find out the main things about spoofing and how to keep your GPS safe.

How does GPS spoofing work and what is it?

GPS signal spoofing occurs when an attacker imitates the original GPS signal by substituting a phoney GPS satellite signal. The "false" signal indicates a change in location, navigation, or time to the recipient.

Have you ever driven to the local mall, but your GPS said that you were at the library? If your GPS has ever told you that you are at an incorrect location, you have likely been the victim of GPS signal spoofing.

How does it work?

To understand how spoofing works, we must first understand how global navigation satellite systems operate. The satellites transmit communication signals to our devices while orbiting the Earth in a medium earth orbit at a height of approximately 20,400 kilometres.

Satellite signals are sometimes rather weak as they must travel such a long distance to reach your device. GPS communications are not encrypted and may be read. As a result, they are an apparent target for anybody wishing to record, transmit, or modify them.

The terrestrial radio transmitter imitates GPS signals with a signal strength that exceeds what the genuine system can handle in a GPS spoofing attack. This replaces authentic GPS signals with fake ones.

But how can a GPS signal be tampered with? This usually includes the utilisation of a GPS spoofing device or spoofing technology, such as an app. They change GPS signals; to spoof, the transmitter must be near the GPS-enabled device. It then imitates the signal to fool the GPS receiver into reporting a different location.

Spoofing technology was formerly difficult to get a hold of. It was once a costly technology only accessible to the military. Now, a transmitter of this kind is already widely accessible. GPS jammers can be found online for as little as 100 USD. As a result, nearly anybody can impersonate GPS signals.

Who falsifies GPS signals and why?

Any satellite navigation-based technique is susceptible to spoofing. The technique of spoofing is practically free, readily accessible, and immensely popular. Virtually everyone uses spoofing, from privacy advocates to Uber drivers, and teenagers.

Since GPS is essentially accessible to everyone, its security has become a big problem. There are several reasons to alter the GPS signal. These consist of:

•  Accessibility to country characteristics

Some individuals use spoofing to alter their device's receivers in order to get access to country-restricted material, services, games, applications, and even television programs and movies.

For instance, certain programs on Hulu, Netflix, and other streaming services are only accessible in particular regions. Since it is impossible to fly to another country in order to view programs, spoofing allows you to modify your true location and access country-restricted content. Many individuals utilise VPNs for this reason.

•  For military purposes

Initial plans were for the military to use GPS equipment. Ironically, the military was the first to falsify GPS. The majority of armed forces may utilise GPS to simulate their position and conceal their activity. For tactical navigation, guided weaponry, and command and control operations, the military may also perform GPS spoofing assaults.

•  To avoid motion tracking and conceal locations

Numerous individuals use spoofing to generate a false GPS position, preventing applications from precisely tracking their activities. Most individuals use this to keep some sense of control over their data by instructing their applications to show an incorrect location.

Additionally, teenagers use spoofing to conceal their whereabouts from their parents. This is how easy spoofing has become.

•  To conceal unlawful conduct

Criminals may also employ spoofing to conceal fraudulent acts such as kidnappings, car thefts, and evidence tampering, or to induce public panic by causing accidents by interfering with automobiles. They may even fake a GPS to send victims to online or physical danger zones.

GPS safety suggestions

Here is some advice on how to prevent GPS spoofing attacks:

•  Install phone antennae

Install bogus antennae in a visible location, away from the genuine ones. This guarantees that spoofing attacks do not disrupt real transmissions. A reasonable distance should be at least 300 metres.

•  Carefully consider where to place your antenna

The antenna's optimum placement should offer an unobstructed view of the sky. Signals from the ground or neighbouring public areas are blocked by buildings and other objects.

Install antennas in areas where they are not visible to the general public, or use barriers such as plastic fencing to hide their position while not interfering with GPS signals.

•  Follow internet hygiene guidelines

Individuals and companies should change and update passwords regularly, install security patches and updates, utilise firewalls and virus protection, and consider adopting multi-factor authentication and other cyber defences to avoid spoofing attacks.

•  Turn off any GPS-enabled gadgets that are not in use

Individuals and businesses that utilise GPS-enabled devices should keep them turned off when not in use. This will keep spoofing attempts at bay.

Install two or more antennae at opposite ends of a building or ship to identify faults and switch to backup navigation systems instantly.

GPS monitoring and location sharing offer significant privacy risks. GPS spoofing may be very dangerous for people, corporations, and governments. Regardless, it enables users to safeguard themselves against security risks and dangers. So, a balance must be achieved.

1. Basic Information about SSL

1.1 What Are ‘Certificates’ and Why Are They Needed?

Certificates are text files on a web server, the placement and content of which confirms the identity of the responsible owner of a web resource. Owner confirmation is carried out by specially authorized companies or divisions of an organization – Certification Centers (also referred to as the CC, Certificate Authority, CA).

Additionally, certificates contain the public key required to establish an encrypted connection to work on a network in order to prevent data interception by intruders. The protocols by which this connection is established end with the letter "S", from the English word "Secure" — see HTTP(S), FTP(S), etc. This means that standard internet protocols, such as HTTP and FTP, are used over an encrypted TLS connection, whereas ordinary messages are exchanged over TCP/IP without encryption. TLS (which stands for Transport Layer Security is a protocol that ensures secure data transfer based on SSL (Secure Sockets Layer), which is another cryptographic protocol. This uses asymmetric cryptography to authenticate exchange keys so that a session can be established, symmetric encryption to further preserve the confidentiality of the session, and the cryptographic signature of messages to guarantee the delivery of information without loss. Despite the fact that it is the only TLS protocol that is actually used, due to habit, the entire family of these protocols is called SSL, and the accompanying certificates are SSL certificates.

The use of SSL certificates primarily allows you to prevent data theft by using clones of sites of well-known services, when attackers duplicate the main pages of said sites, employ similar domain names, and forge personal information forms. The user may input personal information about themselves, their documents, and payment details on fake websites. As a result, users' personal information may subsequently be used to gain unauthorized access to other resources or social networks so it can be resold, or used to steal funds from a bank account. Service owners can help customers avoid these problems by configuring HTTPS on their resource and demonstrating the authenticity of their web pages to their users directly in the browser address bar.

As mentioned above, TLS/SSL is used to encrypt traffic from the client to the web server, and this prevents intruders from intercepting traffic on public unsecured networks.

1.2 How Do They Work?

When it comes to TLS /SSL, three parties are involved: the client – the consumer of services or goods on the internet; the server – the provider of these services or goods; and the Certification Center, whose duties include ensuring that the domain name and resource belong to the organization specified in the registration information of the certificate.

The TLS/SSL algorithm works as follows:

1. The owners of the service contact the Certification Center through partners and provide information about themselves.

2. The Certification Center makes inquiries about the owners of the service. If the primary information is verified, the Certification Center issues the owners of the service with a certificate which includes the verified information and a public key.

3. The user launches a browser on a personal device and goes to the service page.

4. The browser, along with other standard operations, requests the SSL certificate while the service page is loading.

5. The service sends the browser a copy of the certificate in response.

6. The browser checks the validity period and validity of the copy of the certificate using the Certificate Centers’ pre-installed root certificates. If everything is approved, the browser sends the corresponding response to the service, signed with the client's key.

7. The service receives confirmation of the client’s verification with their digital signature and they begin an encrypted session.

Session encryption is carried out using PKI (Public Key Infrastructure). PKI is based on the following principles:

1. There is a related pair of non-interchangeable control sequences of almost random characters called keys: public or public and private, also referred to as private.

2. Any dataset can be encrypted with a public key. Because of this, the public key can be freely transmitted over the network, and an attacker will not be able to use it to harm users.

3. The private key is known only to its owner and can decrypt the received data stream into structured information that has been encrypted with a public key paired with it. The private key should be stored on the service and used only for local decryption of messages that have been received. If an attacker is able to gain access to a private key, then procedures for revoking and reissuing the certificate must be initiated to make the previous certificate useless. A leak of a private key is called a compromise.

An SSL certificate from a Certificate Authority is one way of distributing a server’s public key to clients in unsecured networks. After verifying the validity of the certificate, the client encrypts all outgoing messages with the public key attached to the certificate and decrypts incoming messages with the private one, thereby ensuring a secure communication channel.

1.3 Who Releases Them?

Certificates are issued by Certification Centers upon the request of customers. The Certification Center is an independent third–party organization that officially verifies the information specified in a certificate request: i.e. whether the domain name is valid, whether a network resource with this name belongs to a specific company or individual to whom it is registered; whether the site of the company or individual to whom the SSL certificate was issued is genuine, and other checks. The most famous international Certification Centers are Comodo, Geotrust, GoDaddy, GlobalSign, Symantec. The root SSL certificates of these Certification Authorities are pre-installed as trusted in all popular browsers and operating systems.

It is often more cost-effective to purchase certificates not directly from the Certification Center but from their partners instead, as they offer wholesale discounts. In Russia, many companies and hosting providers that have their own tariffs for the SSL certificate service sell certificates from well-known Certification Centers.

2. Advanced Information about Certificates

2.1 Which Crypto Algorithms Are Used?

The following algorithms are used to establish a secure connection:

• Encryption algorithm
• Hashing algorithms
• Authentication algorithms

The most commonly used encryption algorithms for cryptographic operations in TLS/SSL are combinations of the algorithms RSA (an initialism of the names of the creators Rivest, Shamir and Adleman), DSA (which stands for Digital Signature Algorithm, patented by the National Institute of Standards and Technology of the USA) and several variations of the Diffie–Hellman algorithm or DH, such as a one-time DH (Ephemeral Diffie–Hellman, EDH) and DH based on elliptic curves (Elliptic curve Diffie–Hellman, ECDH). These Diffie-Hellman variations, unlike the original algorithm, provide progressive secrecy, i.e. when previously recorded data cannot be decrypted after a certain amount of time — even if it was possible to obtain the server's secret key — because the original parameters of the algorithm are generated again when the channel is re-established after a forced break when the connection has timed out.

Hashing algorithms are based on a family of mathematical functions for calculating the hash SHA (Secure Hash Algorithm). The hash function allows you to convert the original data array into a string of a certain length, and this length determines the amount of processing time and the computing power required. All encryption algorithms today support the SHA2 hashing algorithm, most often SHA-256. SHA-512 has a similar structure, but in it the word length is 64 bits rather than 32, the number of rounds in the cycle is 80 rather than 64, and the message is divided into blocks of 1024 bits rather than 512 bits. Previously, SHA1 and MD5 algorithms were used for the same purpose, but today they are considered vulnerable to attack. Modern services use keys 64 bits long and higher. The current version of the SHA-3 algorithm (Keccak), uses an amount necessary to verify the integrity of the transmitted data — MAC (Message Authentication Code). The MAC uses the mapping function to represent message data as a fixed length value, and then hashes the message.

In modern versions of the TLS protocol, HMAC is used (Hashed Message Authentication Code), which uses a hash function immediately with a shared secret key. This key is transmitted along with the flow of information, and to confirm authenticity, both parties must use the same secret keys. This provides greater security.

The General Algorithm of SSL Operation

1. Handshake protocol. The connection confirmation (handshake) protocol is the order of operations performed directly during the initialization of the SSL connection between the client and the server. The protocol allows the server and client to carry out mutual authentication, determine the encryption algorithm and MAC, as well as secret keys to protect data during a further SSL session. The handshake protocol is used by participants at the stage before data exchange. Each message transmitted as part of the handshake protocol contains the following fields:

• Type is the category of messages. There are 10 categories of messages.
• Length refers to the length of each message in bytes.
• The content is the message itself and its parameters.

During the handshake, the following stages take place:

1.1 Determination of supported algorithms. At the first stage, the connection between the client and the server is initiated and the encryption algorithms are selected. First, the client sends a welcome message to the server, before entering response-waiting mode. After receiving the client's welcome message, the server returns its own welcome message to the client to confirm the connection. The client's welcome message includes the following data:

• The maximum SSL version number that the client can support
• A 32-byte random number used to generate the master secret
• Session ID
• A list of cipher suites
• A list of compression algorithms

The format of the list of cipher suites is as follows:

<1>_<2>_<3>_<4>

Wherein lies:

• The name of the protocol, for example, "SSL" or "TLS".
• Key exchange algorithm (with an indication of the authentication algorithm).
• The encryption algorithm.
• Hashing algorithm. For example, the entry "SSL_DHE_RSA_WITH_DES_CBC_SHA" means that the fragment "DHE_RSA" (temporary Diffie-Hellman with RSA digital signature) is defined as a key exchange algorithm; the fragment "DES_CBC" is defined as an encryption algorithm; and the fragment "SHA" is defined as a hashing algorithm. As will be discussed later in TLSv1.3, the key exchange and encryption protocols are combined into an authenticated encryption algorithm with attached data (AEAD), so the entry there will be shorter. Example: TLS_AES_256_GCM_SHA384. The server response includes the following fields:
• The SSL version number. On the client side, the lowest version number supported by the client and the largest version number supported by the server are compared. Depending on the server’s settings, selection priority can be given to either the client or server.
• A 32-byte random number used to generate the master secret.
• Session ID.
• A set of ciphers from the list of ciphers supported by the client.
• Compression method from the list of compression methods supported by the client.

1.2 Server authentication and key exchange

At the second stage, all messages are sent by the server. This stage is divided into 4 steps:

• The sending of a digital certificate to the client so they can use the server's public key for authentication purposes.
• Key exchange on the server. Depending on the established algorithm, this step may be skipped.
• Client certificate request. Depending on the settings, the server may require the client to send their own certificate.
• A message confirming that the server authentication and key exchange stage is complete, before moving on to the next stage.

1.3 Client authentication and key exchange:

At the third stage, all messages are sent by the client. This stage is divided into 3 steps:

• The sending of the certificate to the server — if the server requested it (this depends on the established algorithm). If the algorithm includes this, the client can authenticate on the server. For example, in IIS, you can configure mandatory authentication of the client certificate.
• Client key exchange (Pre-master-secret) – the sending of the master key to the server, which will later be encrypted using the server key. The client knows the master key and in case of server substitution will be able to terminate the connection.
• Signing a random number to confirm ownership of the certificate's public key. This stage also depends on the algorithm chosen.

1.4 Server shutdown

At the fourth stage, messages are exchanged directly and errors are monitored. If an error is detected, the alarm protocol comes into effect. This stage consists of exchanging session messages: the first two messages come from the client, and the last two come from the server.

2. The Key Generation Process

To ensure the integrity and confidentiality of information, SSL requires six encryption secrets: four keys and two values of the initialization vector (IV, see below). The information’s authenticity is guaranteed by an authentication key (for example, HMAC). The data is then encrypted by a public key, and data blocks are created based on IV. The keys required by SSL are unidirectional, so when a client is hacked, the data obtained cannot be used to hack the server.

3. Record Agreement (Record Protocol)

The recording protocol is used after a connection between the client and the server has been successfully established, and when the client and server have passed mutual authentication and have determined the algorithm they will use to exchange information about the algorithms used. The recording protocol implements the following functions:

• Confidentiality by using the secret key defined at the handshake stage;
• Integrity by analyzing the MAC defined at the handshake.

4. Alarm Protocol

When the client and server detect an error, they send a message recognizing this. If it is a critical error, the algorithm immediately closes the SSL connection, and both sides first delete the session details: the identifier, secret, and key. Each error message is 2 bytes long. The first byte indicates the type of error. If the connection fails, the value is 1, while if a critical error is detected, it is 2. The second byte indicates the nature of the error.

2.2 Versions of SSL (SSL, TLS) — and How They Differ

During the initial installation of a secure connection between the client and the server, the protocol is selected from those supported by both sides from the set of SSLv3, TLSv1, TLSv1.1, TLSv1.2 or TLSv1.3.

Earlier versions of the SSL protocol are not used. The SSLv1 version was never made public. The SSLv2 version was released in February 1995, but it contained many security flaws that led to the development of SSLv3. Various IT companies have begun to attempt to implement their own versions of secure data transfer protocols. In order to prevent disunity and monopolization in the field of network security, the international community of designers, scientists, network operators, and providers (The Internet Engineering Task Force [IETF]), which was created by the Internet Architecture Council in 1986, is involved with developing protocols and organizing the internet, specifically regarding the standardized TLS protocol version 1, slightly different from SSL 3.0.

The technical details of the protocol are recorded by the release of a document called RFC (Request for Comments, working proposal). These documents can be found on the IETF website: www.ietf.org/rfc/rfcXXXX.txt , where XXXX is a four-digit RFC number. Thus, the TLSv1 version is fixed in RFC 2246, the TLSv1.1 version is fixed in RFC 4346, the TLSv1 version.2 in RFC 5246, and the TLSv1 version.3 in RFC 8446. In addition, RFC 3546 defines several extensions for cases when TLS is used in systems with limited bandwidth, such as wireless networks; RFC 6066 defines a number of additional TLS changes made to the extended client greeting format (presented in TLSv1.2); RFC 6961 defines a method for reducing traffic when a client requests information about the status of a certificate from the server; and, finally, RFC 7925 defines what happens to TLS (and DTLS) when it is used in IoT (Internet Of Things) to exchange data between hardware and other physical objects without human intervention.

As mentioned above, the TLSv1 protocol was released as an update to SSLv3. RFC 2246 states that "the differences between this protocol and SSLv3 are not hugely significant, but they are significant enough to exclude interaction between TLSv1 and SSLv3."

In contrast to the TLS Version 1.0, the TLSv1.1 protocol provides:

• Added protection against attacks using CBC (Cipher Block Chaining), when each block of plaintext is associated with the previous block of ciphertext before encryption.
  1. The implicit initialization vector (the original pseudorandom number initiating the calculation of the further cipher, IV) was replaced by an explicit one which is not secret, but nonetheless cannot be predicted in a reasonable timeframe.
  2. A change in the handling of block filling errors when a data packet is expanded to a fixed block size.
• Support for registering server IP address parameters and other network information.

The TLS 1.2 protocol is based on the TLS 1.1 specification. This is the most common at the moment. The main differences include:

• The combination of MD5–SHA-1 hashing algorithms in a pseudorandom function (PRF) has been replaced by the more secure SHA-256, with the possibility of using a set of ciphers, the specified function.
• The hash size in the finished message has become at least 96 bits.
• The combination of MD5–SHA-1 hashing algorithms in the digital signature has been replaced by a single hash agreed upon during the handshake, which is SHA-1 by default.
• The implementation of the function of selecting encryption and hashing algorithms for the client and server.
• The extension of support for authenticated encryption ciphers used mainly for Galois/Counter mode (GCM) and CCM mode for Advanced Encryption Standard (AES).
• The addition of TLS extension definitions and AES cipher suites.
• The ending of backward compatibility with SSLv2 as part of the 6176 RFC. Thus, TLS sessions have ceased to negotiate the use of SSL version 2.0.

The TLS 1.3 protocol is based on the TLS 1.2 specification. Internet services are gradually transitioning to this protocol. The main differences include:

• The separation of key matching and authentication algorithms from cipher suites.
• The ending of support for unstable and less-used named elliptic curves.
• The ending of support for MD5 and SHA-224 cryptographic hash functions.
• The need for digital signatures even when using the previous configuration.
• The integration of the HMAC-based key generation function and a semi-ephemeral DH sentence.
• The introduction of support for a one-time resumption of the receive-transmit session (Round Trip Time or 1-RTT) handshakes, and initial support for zero time for resuming the receive-transmit session (the name of the 0-RTT mode).
• Session keys obtained using a set of long-term keys can no longer be compromised when attackers gain access to them. This property is called perfect direct secrecy (PFS) and is implemented through the use of ephemeral keys during the DH key agreement.
• The ending of support for many insecure or outdated functions, including compression, renegotiation, ciphers other than AEAD-block encryption modes (Authenticated Encryption with Associated Data), non-PFS key exchange (including static RSA key exchange and static DH key exchange), configurable EDH groups, elliptic curve point ECDH format negotiation, encryption modification specification protocol, UNIX time welcome message, etc.
• The prevention of SSL or RC4 negotiation that was previously possible to ensure backward compatibility.
• The ceasing of use of a record-level version number and fixing the number to improve backward compatibility.
• The addition of the ChaCha20 stream cipher with the Poly1305 message authentication code.
• The addition of digital signature algorithms Ed25519 and Ed448.
• The addition of the x25519 and x448 key exchange protocols.
• The addition of support for sending multiple responses to the Online Certificate Status Protocol, OCSP.
• The encryption of all confirmations of receiving and transmitting a block of data after calling the server.

2.3 What Is PKI (Public Key Infrastructure)?

Public Key Infrastructure (PKI) is a system of software, hardware and regulatory methods that solve cryptographic tasks based on a pair of private and public keys. The PKI is based on the exclusive trust of the exchange participants in the certifying center in the absence of information about each other. The certifying center, in turn, confirms or refutes the ownership of the public key to the specified person who owns the corresponding private key.

The main components of PKI:

• The certifying center or Certification Center is an organization that performs, among other things, legal verification of data on participants in a network interaction (client or server). From a technical point of view, the Certification Center is a software and hardware complex that manages the lifecycle of certificates, but not their direct use. It is a trusted third party.
• A public key certificate (most often just ‘certificate’) consists of client or server data and public key signed with the electronic signature of the Certifying Center. The issuance of a public key certificate by a Certification Authority ensures that the person specified in the certificate also owns the private part of a single key pair.
• Registration Center (RC) is an intermediary of the Certification Center that acts on the basis of trust in the root Certification Center. The Root Certification Center trusts the data received by the Registration Center while verifying the information about the subject. After verifying the authenticity of the information, the Registration Center signs it with its own key and transmits the data it has received to the root Certification Center. The Root Certification Authority verifies the registration authority’s signature and, if successful, issues a certificate. One Registration Center can work with several Certification Centers (in other words, it can consist of several PKIs), just as one Certification Center can work with several Registration Centers. This component may not be present in the corporate infrastructure.
• Repository – a repository of valid certificates and a list of revoked certificates that are constantly updated. The list of revoked certificates (Certificate Revocation List, CRL) contains data on issued certificates whose paid period or validity period have elapsed, as well as certificates of resource owners that have been compromised or have not been authenticated. In the Federal Law of the Russian Federation No. 63 "On Electronic Signatures", this component is called the register of signature key certificates.
• A Certificate Archive is a repository of all certificates ever issued (including expired certificates) within the current PKI. The certificate archive is used for security incident investigations, which include verifying all data that has ever been signed.
• The Request Center is the personal account of the Certification Center’s clients, where end users can request a new certificate or revoke an existing one. It is implemented most often in the form of a web interface for the registration center.
• End users are clients, applications, or systems that own a certificate and use the public key management infrastructure.

3. How the Browser Works with SSL Certificates

3.1 What Happens in the Browser When the Certificate Is Checked?

Regardless of any extensions, browsers should always check a certificate’s basic information, such as the signature or the publisher. Steps for verifying Certificate Information:

1. Checking the integrity of the certificate. This is done with the cryptographic Verify operation with a public key. If the signature is invalid, then the certificate is considered fake: it has been modified after it was issued by a third party, so it is rejected.

2. Verifying the validity of the certificate. This is done with the cryptographic Decrypt operation, and by reading the accompanying information. The certificate is considered valid as long as the period for which the client has paid has not elapsed, or the expiration date has not passed. The expiration date of the certificate is the length of time for which the owner’s identity is validated by the Certifying Center that issued the certificate. Browsers reject any certificates with an expiration date that has expired before or started after the date and time of verification.

3. Checking the certificate revocation status. This is done with the cryptographic Decrypt operation, and loading and reconciliation with CRL. A number of circumstances, for example, law enforcement agencies’ appeals, the identification of a change in the source information or confirmation of the fact that the server's private key has been compromised, can make the certificate invalid before its expiration date. To do this, the certificate is added to the CRL on the side of the Certifying Center.

Certification authorities periodically release a new version of the signed CRL, and it is distributed in public repositories. Browsers access the latest version of the CRL when verifying the certificate. The main drawback of this approach is that it limits verification to the CRL issuance period. The browser will be informed of the revocation only after it receives the current CRL. Depending on the policy of the signing Certification Authority, the CRL update period can be calculated in weeks.

When working with TLSv2 and TLSv3, the browser can use the OCSP Network Certificate Status detection protocol described in RFC 6960. OCSP allows the browser to request the revocation status of a particular certificate online (the reply operation). If the OCSP is configured correctly, the verification of certificates in the CRL is much faster and avoids the use of actually revoked certificates until the next CRL update. There is an OCSP Stapling technology that allows you to include a copy of the response to the certificate status request from the Certifying Center in the headers of the HTTP responses of the web server, which in turn increases the performance and speed of data exchange.

4. Verification of the certificate publisher by the certificate chain.

Certificates are usually associated with several Certification Authorities: the root authority, which is the owner of the public key for signing certificates, and a number of intermediary ones, which refer to previous owners of the public key all the way up to the root one.

Browsers check the certificates of each Certifying Authority for being in the chain of trust with the root at the head. For added security, most PKI implementations also verify that the public key of the Certifying Authority matches the key with which the current certificate was signed. Thus, self-signed certificates are determined, because they have the same publisher only on the server where they were issued, or were added to the list of root certificates.

The X.509 v3 format allows you to determine which chain certificates should be checked. These restrictions rarely affect the average Internet user, although they are quite common in corporate systems at the development and debugging stage.

5. Checking the domain name restriction

The certification authority may restrict the validity of the certificate on a server with a specific domain name or a list of the organization's child domains. Domain name restrictions are often used for intermediate Certification Authority certificates purchased from a publicly trusted Certification Authority to exclude the possibility of issuing valid certificates for third-party domains.

6. Checking the certificate issuance policy

The Certificate Issuance Policy is a legal document published by the Certification Authority, which describes in detail the procedures for issuing and managing certificates. Certification authorities can issue a certificate in accordance with one or more policies, links to which are added to the information of the issued certificate so that the verifying parties can validate these policies before deciding whether to trust this certificate. For example, restrictions may be imposed on the region or time frame (for the period of technological maintenance of the Certification Center software).

7. Checking the length of the certificate chain

The X.509 v3 format allows publishers to define the maximum number of intermediate certification authorities that can support a certificate. This restriction was introduced after the possibility of forgery of a valid certificate was demonstrated in 2009 by including a self-signed certificate in a very long chain.

8. Verifying the public key assignment

The browser checks the purpose of the public key contained in the certificate encryption, signatures, certificate signature and so on. Browsers reject certificates, for example, if a server certificate is found with a key intended only for CRL signing.

9. Checking the rest of the chain certificates

The browser checks each certificate of the chain. If the verification data was completed without errors, then the entire operation is considered valid. If any errors occur, the chain is marked as invalid and a secure connection is not established.

3.2 How to View Certificate Information and Check that Everything Is Working Correctly

The security certificate can be checked directly in the browser. All modern browsers display certificate information visibly in the address bar. If a secure connection with a web resource is established, a lock icon is displayed on the left of the browser address bar. In case of an error, the crossed-out word "HTTPS" or an open lock icon will be displayed. Depending on the type of browser and its version, the type of icons and behavior when working with SSL certificates may differ. Below are examples of images for different versions of modern browsers:

Google Chrome

Mozilla Firefox

Opera

Microsoft Edge

Chrome for Android

Safari for iOS

To view the details of the certificate, click on the lock icon and in the subsequent menu, click on the option that outlines the security details. Information about the certificate will appear after clicking on the appropriate button or information link.

Google Chrome

Mozilla Firefox

Microsoft Edge

Chrome for Android

3.3 A Message that the Browser Does Not Trust the Certificate

Most browsers display a security warning. These warnings inform you that the certificate has not been verified by a trusted certificate authority.

There are a number of reasons why an SSL certificate may be considered invalid in the browser. The most common reasons are:

• Errors in the certificate chain installation process, the intermediate certificate is missing;
• The SSL certificate has expired;
• The SSL certificate is valid only for the primary domain, not for subdomains;
• A self-signed SSL certificate has been used, or the root certificate of the Certification Authority has not been added to the trusted list on the current device.

4. Certification Centers

4.1 More Details about the Certification Centers

As mentioned above, the main task of the Certification Center is to confirm the authenticity of encryption keys using electronic signature certificates. The overarching operating principle can be described by the phrase "users do not trust each other, but everyone trusts the Certifying Center."

Any HTTPS interaction is based on the fact that one participant has a certificate signed by the Certification Authority, and the other attempts to verify the authenticity of this certificate. Verification will be successful if both participants trust the same Certification Authority. To solve this problem, the Certification Center’s certificates are preinstalled in operating systems and browsers. If the Certification Authority itself has issued a certificate, it is called a root certificate. A certificate issued by a partner of the Certification Authority with which it has a trust relationship is called an intermediate certificate. As a result, a tree of certificates is formed with a chain of trust between them.

By installing the certificate of the Certifying Center in the system, you can trust the certificates that have been signed with it. A certificate (particularly for HTTPS) that is issued but not signed by a root or intermediate Certification authority is called a self-signed certificate and is considered untrusted on all devices where this certificate is not added to the root/intermediate lists.

According to the distribution level of certificates, the Certification Center can be international, regional, and corporate. The public key management infrastructure’s activities are carried out in accordance with the regulations of the appropriate level: i.e. public directives recorded by the international community of Internet users, the legislation of the region, or the relevant provisions of the organization.

The main functions of the certification center are:

• verifying the identity of future certificate users;
• issuing certificates to users;
• revoking certificates;
• maintaining and publishing lists of revoked certificates (Certificate Revocation List/CRL), which are used by public key infrastructure clients when they decide whether to trust a certificate.

Additional functions of the certification center are:

• Generating key pairs, one of which will be included in the certificate.
• Upon request, when resolving conflicts, the UC can verify the authenticity of the electronic signature of the owner of the certificate issued by this UC.

Browsers and operating systems of devices fix the trust of the Certifying Center by accepting the root certificate into their storage – a special database of root certificates of Certifying centers. The storage is placed on the user's device after installing the OS or browser. For example, Windows maintains its root certificate store in operating systems, Apple has a so-called trust store, Mozilla (for its Firefox browser) creates a separate certificate store. Many mobile operators also have their own storage. Regional and corporate should be added either at the stage of software certification in the country, or by contacting the technical support of the organization.

Regional representatives of the world Certification Centers have the authority to make legal requests for the activities of organizations related to the publication of web resources. For corporate Certification Centers, this is not necessary, since they usually have access to the internal information of the organization. For security purposes, Certification Authorities should not issue digital certificates directly from the root certificate transmitted to operators, but only through one or more Intermediate Certificate Authority, ICA. These intermediate Certification Authorities are required to comply with security recommendations in order to minimize the vulnerability of the root Certification authority to hacker attacks, but there are exceptions. For example, GlobalSign is one of the few certification authorities that have always (since 1996) used ICA.

Certificates come in different formats and support not only SSL, but also the authentication of people and devices, as well as certifying the authenticity of code and documents. Within the Russian legislative framework, such activities must be licensed by the FSB, since they are related to cryptographic operations.

The universal algorithm for obtaining a certificate from the Certification Center:

1. Private key generation
2. Creation of a certificate signing request (CSR request)
3. Procurement of a certificate signed by the Certificate Authority’s root certificate after passing the checks
4. Configuration of the web server for your resource

Since browsers have a copy of the international Certification Authority’s root certificate, as well as a number of intermediate certificates from the chain of trust, the browser can check whether a certificate was signed by a trusted certification authority. When users or an organization create a self-signed certificate, the browser does not trust it as it knows nothing about the organization, so the root certificate of the organization must be manually added to all controlled devices. These certificates will become trusted after this.

4.2 What Are Root Certificates?

A root certificate is a file that contains service information about the Certification Authority. Special software or a library that verifies, encrypts and decrypts information is called a crypto provider (a provider of cryptographic functions). The cryptographer gets access to the encrypted information, thereby confirming the authenticity of the personal electronic signature.

A chain of trust for the certificates is then built based on the certifying center’s root certificate. Any electronic signature issued by the Certifying Center only works if there is a root certificate.

The root certificate stores information with the dates of its validity. The cryptographic provider can also get access to the organization's registry through the root certificate.

4.3 What Is a Certificate Chain?

Historically and technologically, certain Certification Centers are widely recognized among SSL users, and as a result, it was agreed that the certificates they issued would be considered root certificates, and they would always be trusted. Regional Certifying certificates, in turn, can be confirmed by the root Certifying center. In turn, they can confirm other certificates, forming a chain of trust to certificates. The Certifying Center acts as a guarantor-certifier which issues an SSL certificate at the request of the owner of a web resource.

The certificate and the web resource to which it is issued are certified by an electronic digital signature (EDS). This signature indicates who the owner of the certificate is and records its contents, that is, it allows you to check whether it has been changed by someone after it was issued and signed.

The list of certificates of root Certifying centers and their public keys is initially placed in the operating system’s software storage on the users' workstation, in the browser, and in other applications that use SSL.

If the chain of sequentially signed certificates ends with the root certificate, all certificates included in this chain are considered confirmed.

Root certificates located on the user's workstation are stored in a container protected by the operating system from accidental access. However, the user can add new root certificates themselves, and this is a source of potential security problems.

By carrying out certain actions and accessing an attacked workstation, an attacker can include their own certificate among the root certificates and use it to decrypt the data that is received.

The Root Certification Center can be formed by the government of a particular country or the leaders of an organization. In these cases, root Certification Centers will not operate everywhere, but they can nonetheless be used quite successfully in a specific country or within a specific enterprise.

At present, the list of root certification authorities on the user's computer can be automatically changed when updating the operating system, software products, or manually by the system administrator.

Certification centers can issue a variety of SSL certificates linked by what is known as a tree structure. The root certificate is the root of the tree, with the secret key with which other certificates are signed. All intermediate certificates that are at a lower level inherit the degree of trust that the root certificate has. SSL certificates located further down the structure receive trust in the same way from the Certifying Centers located higher up the chain. Using the example of the Comodo Certification Center, the structure of SSL certificates can explained as follows:

1. The root certificate of the Comodo Certification Authority: AddTrustExternalCARoot

2. Intermediate Certificates: PositiveSSL CA 2, ComodoUTNSGCCA, UTNAddTrustSGCCA, EssentialSSLCA, Comodo High-Assurance Secure Server CA

3. SSL certificates for individual domains

5. General Information about Certificate Types

5.1 Paid Trusted Certificates

The purchase of trusted certificates, except in some cases, is a paid service.

5.1.1 Where and How to Buy

In most cases in Russia, web resource hosting companies or partner organizations of international Certification centers provide SSL certificate services. It is possible to purchase certificates directly from Certification Centers, but such certificates are usually more expensive than from partners who purchase them in bulk.

The procedure for purchasing an SSL certificate is no different from purchasing other internet services. It entails:

1. Selecting a supplier and going to the SSL certificates order page.

2. Selecting the appropriate SSL certificate and clicking the purchase button.

3. Entering the name of your domain and selecting the protection option — for one domain or Wildcard certificate for a group of subdomains.

4. Paying for the service in whichever way is most convenient.

5. Continue configuring the service in accordance with the following parameters:

a. The number of domains that the certificate protects (i.e. one or more).
b. Subdomain support.
c. The speed of release. Certificates with domain-only validation are issued the quickest, while certificates with EV validation are issued the slowest.
d. Most Certifiers offer unlimited certificate reissues. This is required if there are mistakes in the organization data.
e. Warranty – for some certificates there is a $10,000 warranty. This is a guarantee not for the certificate buyer, but rather for the visitor of a site that installs a certificate. If a site visitor with such a certificate suffers from fraud and loses money, the Certification Center undertakes to compensate the stolen funds up to the amount specified in the guarantee. In practice, such cases are extremely rare.
f. Free trial period – Symantec Secure Site, Geotrust Rapidssl, Comodo Positive SSL, Thawte SSL Web Server certificates have paid certificates. There are also free certificates.
g. Refund – almost all certificates have a 30-day refund policy, although there are certificates without this.

5.1.2 Approximate Cost

SSL certificates can be separated into different groups based on their properties.

1. Regular SSL certificates. These are issued instantly and confirm only one domain name. Cost: from $20 per year

2. SGC certificates. These support customers with increasing the level of encryption. Server Gated Cryptography technology allows you to forcibly increase the encryption level to 128 bits in older browsers that supported only 40 or 56 bit encryption. Cryptography is used to solve this problem, but it cannot cope with the other vulnerabilities present in unsecure browsers, so there are a number of root Certification centers that do not support this technology. Cost: from $300 per year.

3. Wildcard certificates. They provide encryption of all subdomains of the same domain by mask. For example, there is a domain domain.com; if the same certificate must be installed on support.domain.com , forum.domain.com and billing.domain.com , customers can issue a certificate for *.domain.com . Depending on the number of subdomains that need the certificate, it may be more cost-effective to purchase several ordinary SSL certificates individually. Examples of wildcard certificates: Comodo PositiveSSL Multi-Domain Wildcard and Comodo Multi-Domain Wildcard SSL. Cost: from $180 per year.

4. SAN Certificates Subject Alternative Name technology allows customers to use one certificate for several different domains hosted on the same server. Such certificates are also referred to as UCC (Unified Communication Certificate), MDC (Multi-domain certificate) or EC (Exchange Certificate). Generally, one SAN certificate includes up to 5 domains, but this number can be increased for an additional fee. Cost: from $395 per year.

5. Certificates with IDN support Certificates with national domain support (International Domain Name, such as *.RU, *.CN, *.UK). Not all certificates can support IDN. This must be clarified with the Certification Center. Certificates supporting IDN include:

• Thawte SSL123 Certificate;
• Thawte SSL Web Server;
• Symantec Secure Site;
• Thawte SGC SuperCerts;
• Thawte SSL Web Server Wildcard;
• Thawte SSL Web Server with EV;
• Symantec Secure Site Pro;
• Symantec Secure Site with EV;
• Symantec Secure Site Pro with EV.

As is mentioned above, partners of Certification Centers can provide significant discounts on prices — starting at $10 — or offer service packages.

5.1.3. Certificate Validation

Certificates are divided into the following levels of validation:

1. DV

Domain Validation, or certificates with domain validation. The certification authority verifies that the client who requests the certificate controls the domain that needs the certificate. A network service for verifying the ownership of WHOIS web resources is used to do this. This type of certificate is the cheapest and most popular, but it is not completely secure, since it contains only information about the registered domain name in the CN field (CommonName is the common domain name of a web resource).

2. OV

Organization Validation, or certificates with organization verification. The certification center verifies the affiliation of a commercial, non-profit or government organization to the client, who must provide legal information when purchasing. This type of certificate is seen as more reliable, since it meets the RFC standards and also confirms the registration data of the owner company in the following fields:

• O (Organization – name of the organization);
• OU (Organizational Unit – name of the organization's division);
• L (Locality – name of the locality of the organization’s legal address);
• S (State or Province Name – name of the territorial and administrative unit of the organization’s legal address);
• C (Country Name – the name of the organization's country).

The certification center can contact the company directly to confirm this information. The certificate contains information about the person that confirmed it, but not data about the owner. An OV certificate for a private person is called IV (individual validation/ individual verification) and verifies the identity of the person requesting the certificate.

3. EV

Extended validation, or a certificate with extended validation. The Certification Center verifies the same data as the OV, but in accordance with stricter standards set by CA/Browser Forum. CA/Browser Forum (Certification Authority Browser Forum)is a voluntary consortium of certification authorities, developers of Internet browsers and software for secure email, operating systems, and other applications with PKI support. The Consortium publishes industry recommendations governing the issuing and management of certificates. This type of certificate is considered the most reliable. Previously, when using these certificates in a browser, the color of the address bar changed and the name of the organization was displayed. It is widely used by web resources that conduct financial transactions and require a high level of confidentiality. However, many sites prefer to redirect users to make payments to external resources confirmed by certificates with extended verification, while using OV certificates which are secure enough to protect the rest of the user data.

5.1.4. The Setup Process (General Information, What Is CSR?)

To initiate the certificate issuing process, a CSR request must be made. Technically, a CSR request is a file that contains a small fragment of encrypted data about the domain and the company to which the certificate is issued. The public key is also stored in this file.

The CSR generation procedure depends entirely on the software used on your server, and is most often performed using the settings in the administrative panel of your hosting. If your hosting does not provide this, then you can use online services to generate a CSR request, or alternatively you can turn to specialized software, such as OpenSSL, GnuTLS, Network Security Services, etc. After generating the CSR, the private key will also be generated.

To successfully generate a CSR, you need to enter data about the organization that has requested the certificate. The information must be entered in the Latin alphabet. The following parameters are sufficient:

• Country Name — the country of registration of the organization in two-letter format. For the Russian Federation — RU;
• State or Province Name — region, region of registration of the organization. For Moscow — Moscow;
• Locality Name — the city where the organization is registered. For Moscow — Moscow;
• Organization Name — the name of the organization. For individuals, "Private Person" is indicated;
• Common Name — the domain name of those who have requested the certificate;
• Email Address — the administrator’s email address. Acceptable values:
  • admin@domain_name;
  • administrator@domain_name;
  • hostmaster@domain_name;
  • postmaster@domain_name;
  • webmaster@domain_name.

5.2. Self-Signed Certificates

Self–signed certificates are SSL certificates created by the service developers themselves. A pair of keys for them is generated through specialized software, for example, OpenSSL. Such a communication channel may well be used for internal purposes, i.e. between devices within your network or applications at the development stage.

5.3. Let’s Encrypt

Let's Encrypt is an Authentication Center that provides free X.509 cryptographic certificates for encrypting HTTPS data transmitted over the Internet and other protocols used by servers on the Internet. The process of issuing certificates is fully automated. The service is provided by the public organization Internet Security Research Group (ISRG).

The Let's Encrypt project was started to translate most of the Internet sites to HTTPS. Unlike commercial Certification centers, this project does not require payment, reconfiguration of web servers, use of e-mail, or the processing of expired certificates. This simplifies the installation and configuration of TLS encryption. For example, on a typical Linux-based web server, you need to run two commands that will configure HTTPS encryption, receive and install a certificate in about 20-30 seconds.

Let's Encrypt root certificates are installed as trusted by major software vendors, including Microsoft, Google, Apple, Mozilla, Oracle and Blackberry.

The Let's Encrypt Certification Authority issues DV certificates with a validity period of 90 days. It has no plans to start issuing OV or EV Certificates, although it began providing support for Wildcard certificates some time ago.

The key to the root certificate of the RSA standard has been stored in the HSM hardware storage since 2015 and is not connected to the network. This root certificate is signed by two intermediate root certificates, which were also signed by the IdenTrust certification authority. One of the intermediate certificates is used to issue sites’ final certificates, while the second is kept as a backup in storage that is not connected to the Internet, in case the first certificate is compromised. Since the root certificate of the IdenTrust center is preinstalled in most operating systems and browsers as a trusted root certificate, the certificates issued by the Let's Encrypt project are verified and accepted by clients — despite the absence of the ISRG root certificate in the trusted list.

The Automated Certificate Management Environment (ACME) authentication protocol is used to automatically issue a certificate to the destination site. In this protocol, a series of requests are made to the web server that seeks a signature for the certificate to confirm the ownership of the domain (DV). To receive requests, the ACME client configures a special TLS server, which is polled by the ACME server using Server Name Indication (Domain Validation using Server Name Indication, DVSNI).

Validation is carried out repeatedly, using different network paths. DNS records are pulled from a variety of geographically distributed locations to prevent DNS spoofing attacks. This is when domain name cache data is changed by an attacker in order to return a false IP address and redirect the intermediary to the attacker's resource (or any other resource on the network)1.

6. Paid Trusted Certificates

6.1 Usage on Windows Server and IIS

6.1.1 What Are the Formats of the Private Key?

These are today’s private key formats:

1. PEM format

This format is most often used by Certification Authorities. PEM certificates most often have extensions *.pem, *.crt, *.cer or *.key (for private keys) and others. For example, the package file SSL.com The CA available in the download table in the order of the certificate has the extension *.ca-bundle. The contents of the files are encrypted using Base64 and contain the strings "--BEGIN CERTIFICATE--" and "--END CERTIFICATE--".

This certificate format is common in Linux OS. Multiple PEM certificates and even a private key can be included in one file, one under the other. But most servers, such as Apache, expect the certificate and private key to be in different files.

2. PKCS#7/P7B format

PKCS#7 or P7B format certificates are usually saved in Base64 ACVII format and have the extension *.p7b or *.p7c. The P7B certificate contains the strings "--BEGIN PKCS7--" and "--END PKCS7--". This format contains only the certificate and certificate chain, but not the private key. Several commonly-used platforms support this format, including Microsoft Windows and Java Tomcat.

3. PKCS#12/PFX format

PKCS#12 or PFX format is a binary format for saving a certificate, any intermediate certificates, and a private key in one encrypted file. PFX files are usually saved with the extension *.pfx or *.p12. As a rule, this format is used on Windows certificates to export/import the certificate and private key 2.

6.1.2 How to Generate a CSR Request

To generate a CSR request in IIS 10, perform the following operations:

1. Run IIS from the iis.msc command line or from the visual interface.

2. Select your server from the Connections list and click the Server Certificates button.

3. On the Server Certificates page, click the Create Certificate Request link in the Actions block.

4. In the Request Certificate window of the wizard, fill in the CSR fields and click Next.

5. In the Cryptographic Service Provider Properties window of the wizard, select the required cryptographic provider, depending on the desired algorithm and the key length, and then click Next.

6. In the File Name window of the wizard, specify the path to the CSR being created, and then click Finish.

To send the finished CSR to the Certification Center, open the file in a text editor and copy the contents to the web form of the certificate provider.

6.1.3 How to Create a Private Key

As a result of creating the CSR, the private key will be created automatically by IIS. Viewing is available on the Certificates console snap-in in the Personal or Web Hosting points of the certificate tree.

The snap-in can be hidden in the console. To add it, run the mmc command in Start menu > Run and in the window that appears, add the Certificates snap-in to the list available on the local machine:

6.1.4 How to Export It

To export a private key for backup purposes or to configure a new server, follow these steps:

1. Find the certificate in the Certificates snap-in of the management console, and right-click on it. In the context menu that appears, click on the menu item All Tasks > Export;

2. In the Welcome to the Certificate Export wizard window of the Certificate Export Wizard, click Next and then in the Export Private Key window, set the switch to Yes, export the private key, and then click Next;

3. In the Export File Format window of the wizard, select the type item Personal Information Exchange – PKCS #12 (.PFX) and select the checkbox Include all certificates in the certification path if possible. Then click Next. Be aware that if the Delete the private key if the export is successful checkbox is checked, the private key created on the current server will be deleted after export;

4. In the Security wizard window, fill the Password checkbox and enter the password twice to protect the private key. It will be required for the subsequent import. Additionally, it is recommended that Active Directory users or groups that have the ability to use a private key are restricted. To do this, fill the Group or User Name checkbox and select Required Groups or Users, then click Next;

5. In the File to Export window of the wizard, specify the path to the exported file with the private key and its name. To do this, enter it manually or use the system file search dialog box, then click Next;

6. In the File to Export window of the wizard, specify the path to the exported file with the private key and its name. To do this, enter it manually or use the system file search dialog box, and then click Next. In the next window Completing the Certificate Export Wizard, a list of the installed settings will appear. Click Finish. The exported file will appear in the specified directory.

6.1.5 How to Configure SSL on IIS

To configure SSL in IIS, follow these steps:

1. Run IIS from the iis.msc command line or from the visual interface.

2. Select your server from the Connections list and click on the Bindings... link in the Actions block.

3. In the Site Bindings window, click Add.

4. In the Add Site Bindings window, fill in the following fields and click OK.

• IP address – select the IP addresses of the servers with which the certificate will be associated from the drop-down list or click the All Unassigned button to associate the certificate with all servers.
• Port – leave the value 443. This is a standard SSL port.
• SSL certificate – select the required SSL certificate from the drop-down list.

The setup is finished, you can check the operation of the web service. If the private key is missing, then import it in the Certificates snap-in of the Management console. To do this, select the desired resource and right-click on it. Then, in the context menu that appears, click on the menu item All Tasks > Import, and follow the instructions of the wizard.

6.2 Usage on Linux

6.2.1 How to Create a Private Key

The private key that has been created can be obtained in the interface of the SSL certificate provider after sending the CSR or using specialized software, such as OpenSSL, for example.

Below is a fragment of private key generation in the web interface of the SSL certificate provider.

If the private key was created in the web interface, then the export is carried out by clicking the button there. After clicking on the button, the browser starts downloading the archive with the key file in the desired format.

To create a private RSA key using OpenSSL, one command is enough:

openssl genrsa -out rsaprivkey.pem 2048

This command generates the PEM private key and stores it in the rsaprivkey.pem file. In our example, a 2048-bit key is created, which is suitable for almost all situations.

To create a DSA key, you need to perform two steps:

openssl dsaparam -out dsaparam.pem 2048
openssl gendsa -out dsaprivkey.pem dsaparam.pem

The first step creates a DSA parameters file (dsaparam.pem), which in this case contains instructions for OpenSSL to create a 2048-bit key in step 2. The dsaparam.pem file is not a key, so it can be deleted after the public and private keys are created. In the second step, a private key is generated (dsaprivkey.pem file), which must be kept secret.

To create a file in the PKCS#12 format used in Windows OS, use the following command:

openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt

Where:

• pkcs12 – private key format;
• export – the operation of exporting the private key to the required format;
• out – the directory in the file system where the resulting file should be placed;
• inkey – private key file in PEM format;
• in – file of the certificate received from the Certifying Center;
• certfile is a copy of the root certificate and intermediate certificates in the chain. In the example above, they are missing.

6.2.2 How to Generate a CSR Request

To generate a CSR, fill in the suggested fields in the web form of the SSL certificate service provider. The figure above demonstrates an example of this. The set of minimum required fields is the same and is given in the section about CSR description, but some vendors can add their own or change the input method.

To generate CSR using OpenSSL, use the following command:

openssl req -new -key private.key -out domain_name.csr -sha256

Where:

• new – creating a new CSR request by direct input in the console. Without this option, the OpenSSL configuration file data will be used;
• key – the name of the private key required for generation. If the option is not specified, a new private key will be created according to the default algorithm;
• out – the path to the CSR file being created;
• sha256 is an encryption algorithm.

After executing the command, a request to fill in the required fields will appear in the console.

Then send the resulting CSR to the Certifying Center. In response, a personal certificate must be returned.

6.2.3 How to Configure SSL for Apache

Follow these steps to configure SSL in Apache:

1. Add the personal certificate issued by the Certification Authority, the private key, and the root certificate to the /etc/ssl/ directory — along with the rest of the certificates in the chain.

2. Open the Apache configuration file with any text editor: vim, for example. Depending on the server OS, the file may be located in one of the following locations:

• for CentOS: /etc/httpd/conf/httpd.conf;
• for Debian/Ubuntu: /etc/apache2/apache2.conf;

3. If you are installing an SSL certificate on an OpenServer, use the path to its root folder. At the end of the file, create a copy of the "VirtualHost" block. Specify port 443 for the block and add the following lines inside:

SSLEngine on
SSLCertificateFile /etc/ssl/domain_name.crt
SSLCertificateKeyFile /etc/ssl/private.key
SSLCertificateChainFile /etc/ssl/chain.crt

4. Check the Apache configuration before restarting with the command: apachectl configtest, then restart Apache.

6.2.4 How to configure SSL for Nginx

Follow these steps to configure SSL in Nginx:

1. Open a text editor and add the contents of the personal certificate issued by the Certification Authority, and the root certificate — along with the rest of the certificates in the chain. The resulting file should look like this:

----BEGIN CERTIFICATE-----
#Your certificate#
----END CERTIFICATE-----
----BEGIN CERTIFICATE-----
#Intermediate certificate#
----END CERTIFICATE-----
----BEGIN CERTIFICATE-----
#Root certificate#
----END CERTIFICATE-----

2. Save the resulting file with the *.crt extension to the /etc/ssl/ directory. Please note: the second certificate should come directly after the first, without any empty lines.

3. Save the your_domain file.key with the certificate's private key in the /etc/ssl directory.

4. Open the Nginx configuration file and edit the virtual host of your site that you want to protect with a certificate. Perform the minimum setup for the job by adding the following lines to the file:

server {
listen 443 ssl;
server_name your_domain.com;
ssl_certificate /etc/ssl/your_domain.crt;
ssl_certificate_key /etc/ssl/your_domain.key;
}

Where:

• your_domain.com — the domain name of the site;
• /etc/ssl/your_domain.crt — the path to the file created with three certificates;
• /etc/ssl/your_domain.key — the path to the file with the private key.

The names of files and directories can be arbitrary.

Additionally, you can configure the operation of the site over HTTP, the type of server cache, the cache update timeout, and the operating time of a single keepalive connection. You can also configure the supported protocols and their level of priority (server set or client set), as well as OCSP responses for certificate validation. Details are given in the Nginx user manual.

5. For the changes to take effect, restart the Nginx server with the following command:

sudo /etc/init.d/nginx restart

7. Self-Signed Certificates

7.1 Usage on Windows Server and IIS

7.1.1 How to Create a Private Key

8. Let’s Encrypt

8.1 Usage on Windows Server and IIS

8.1.1 How to Issue a Certificate

To install the Let's Encrypt certificate, an ACME client must be installed on the server. The following implementations are common for Windows:

• The Windows ACME Simple Utility (WACS) is a command–line utility for interactively issuing a certificate and binding it to a specific site on your IIS web server;
• The ACMESharp Powershell module is a Powershell library. It has many commands for interacting with Let's Encrypt servers via the ACME API;
• Certify is a graphical SSL certificate manager for Windows that allows you to interactively manage certificates via the ACME API.

To issue a Let's Encrypt certificate using WACS, follow these steps:

1. Download the latest release of the WACS client from the project page on GitHub https://github.com/PKISharp/win-acme/releases and unpack it onto a directory on the server.

2. Open a command prompt and run the client wacs.exe from the specified location.

3. Press the N key. This will create a certificate for IIS.

4. Select the certificate type: DV for one domain, DV for all domains in IIS (SAN), domains corresponding to Wildcard, or a manual list of domains in IIS.

5. Depending on the choice, WACS.exe will display a list of sites running on the IIS server and will prompt you to select the desired site.

6. After selecting the site, provide an email address to receive information about problems including site certificate updates (several addresses can be given if they are separated by commas).

7. Agree to the terms of use by pressing the Y key, after which Windows ACME Simple will connect to Let's Encrypt servers and try to automatically generate a new SSL certificate for the site 3.

8.1.2 How to Configure IIS for Let's Encrypt Certificate

The WACS utility saves the certificate's private key (*.pem), the certificate itself, and a number of other files to the directory C:\Users\%username%\AppData\Roaming\letsencrypt-win-simple . It will then install the generated Let's Encrypt SSL certificate in the background and bind it to your IIS site.

For more details, see here https://www.win-acme.com/manual/getting-started

8.2 Usage on Linux

8.2.1 How to Issue a Certificate

To install the Let's Encrypt certificate, the ACME client must be installed on the server. For Linux, this is the Certbot utility.

To issue a Let's Encrypt certificate using Certbot, follow these steps:

1. Install Certbot according to the instructions on the website https://certbot.eff.org / to the server.
2. Execute the certificate issue command: certbot --nginx or certbot --apache. When launching for the first time, an email address for receiving information about problems site certificate updates and other alerts may be required.

Certbot will analyze the ServerName directive that corresponds to the domain name with the requested certificate in the web server’s configuration files. If you need to specify multiple domains or wildcard, use the command line key -d.

For more details, see: https://certbot.eff.org/instructions

8.2.2 How to Configure IIS for a Let's Encrypt Certificate

After executing the certbot command, the web server configuration will be updated automatically. The certbot client will display a successful completion message, and will also show the path to the directory where the certificates are stored.

9. Certificate Renewal for Linux and Windows

9.1 Paid Trusted

When extending the validity of the SSL/TLS certificate, creating a new CSR request is recommended. Generating a new request will create a new unique key pair (public/private) for the updated certificate.

The web interface of many SSL certificate providers allows you to renew the certificate manually or automatically. After renewing, the user will receive a new reissued certificate. This needs to be reconfigured again in accordance with the instructions above.

9.2 Self-Signed

Self-signed certificates are renewed by recreating and configuring the web server in accordance with the instructions described above.

9.3 Let’s Encrypt

9.3.1 On Windows

Windows ACME Simple creates a new rule in the Windows Task Scheduler (called win-acme-renew) to automatically renew the certificate. The task is started every day, and the certificate renewal itself is performed after 60 days. When extending, the scheduler runs the command:

C:\\<path to the WACS directory>\\wacs.exe --renew --baseuri "<https://acme-v02.api.letsencrypt.org >"

You can use the same command to manually update the certificate.

9.3.2 On Linux

To renew the certificate via certbot, you need to run the following command:

certbot Renew --force-Renewal

To specify a specific domain, use the -d parameter.

10. Testing

10.1 Services (SSL Checkers) that Allow You to Check SSL Tinctures on a Public Server

Professionally coordinated operational communications allow warfare to be done while preventing escalation and/or emergency scenarios.

In order to ensure the highest possible security of soldier communications on missions, to prevent espionage, and perhaps even to win the war, it is necessary to use a large number of military information and communication technologies. They should not only protect and provide communications for operational activities but also enable an exchange between military personnel at the "internal" and "secret" communication levels.

Nowadays, the use of mobile devices for communication has become so commonplace that it has even spread to the industries of military and defence. This scenario uses programs for communication, which are often called instant messengers.

The armies of different countries are looking for secure ways to exchange messages. Some are turning to already available commercial solutions, while others are developing their messengers with the help of the open-source community. Let's take a look at what messengers are used in the armies of the world, and what are their features, advantages, and disadvantages.

USA

The US military leadership suggested the use of encrypted messengers Signal and Wickr in combat zones, including in the Middle East. Both were created by the open community and are available for free download.

Open Whisper Systems created Signal, which uses its proprietary Signal System encryption protocol, which is used by other messengers. Wickr has created a military-specific RAM version. End-to-end encryption is provided for chat messaging, audio and video conversations, secure screen sharing, and massive file transmission and storage.

The usage of Signal and Wickr, on the other hand, violates the US Freedom of Information Act, which states that email and text messages received in official government activities are public and must be made accessible upon request. At the same time, both messengers offer the ability to delete messages, which are not saved on senders' or receivers' devices or the company's servers.

France

European governments seeking digital sovereignty are developing messengers such as Matrix using decentralised messaging protocols. The adoption of such a protocol enables you to store data in the application developer's infrastructure. This software's messenger contains open source code, solid end-to-end encryption, and is decentralised. The Matrix-based system was developed by the French Armed Forces. In 2019, they developed the Tchap messenger to replace Telegram, which was previously used by local government departments for communication.

Germany

The German armed services also utilise the Matrix-based BwChat messenger for military communications. The messenger, developed with the help of the nation's Armed Forces' Cyber Innovation Center and Stashcat, provides a secure communication route not only while deployed in the country, but also when deployed overseas. Because of end-to-end encryption and mobile application management, it may be accessed from both professional and personal devices (MAM). In a safe communication environment that conforms with data security and GDPR, BwChat blends traditional chat features with cloud storage.

Each user gets their own file storage area and each conversation has its own storage space. User data is encrypted and handled in line with German data protection legislation in a server centre in Hannover.

The program allows for secure document sharing, an infinite number of conversation participants and the surveillance and organisation of movements using the "Share GPS Location" function. It is not dependent on the user's contacts list.

Switzerland

Except for the native messenger Threema, the Swiss Army prohibited all chat applications in 2022. The military can no longer use Signal, Telegram, or WhatsApp.

Because Threema does not require users to enter a phone number or email address when enrolling, no identity may be determined using publicly available information. At the same time, the messenger allows you to identify persons in your contact list by their QR codes.

Israel

In the year 2020, the IDF developed a messenger that was functionally equivalent to WhatsApp. It looks and operates just like WhatsApp, but it has additional privacy protections built in for sending extremely sensitive operational data, such as while conducting reconnaissance.

India

The Indian Army introduced its SAI texting app in 2021. It is comparable to commercial competitors WhatsApp, Telegram, and Signal in that it enables end-to-end encryption for voice, text messaging, and video conversations.

The Indian app offers enhanced security protections since all data is handled on local servers.

China

There is no open source information available on the Chinese military's usage of instant messengers. Furthermore, most major instant messengers and social networks, including Facebook, Instagram, Twitter, Whatsapp, Telegram, Viber, and even ICQ, are restricted in the nation. Local military troops are most likely using WeChat, the country's most popular and government-controlled messenger.

The safety and security of data are extremely important, particularly when it comes to the official communications of the military and in the institutions of the defence sector. Every officer in the armed forces is responsible for ensuring the safety and well-being of their colleagues. The success rate of successfully protecting secret and personal information is directly proportional to the level of security, encryption, and compartmentalization of the connection.

Quantum computers, which are very particular kinds of computers, are capable of solving problems in a very short amount of time, even those that would take a supercomputer a very long time to solve. It is true that doing these tasks is still a long way from being a reality, and quantum systems have many limitations. But, as we all know, progress is a never-ending process, and it is possible that in the not-too-distant future, this technology will rule the planet. Let's have a conversation about how this cutting-edge technology may impact our security.

Data encryption is the key to online security

Encryption is essential to the protection of data on computers and other Internets. Encrypting data entails utilizing a secret rule and a collection of characters, known as ‘the key’, to turn it into a meaningless jumble. To comprehend what the sender was trying to communicate, one will have to decode the ‘porridge’ using the key.

One of the most basic types of encryption is when each letter is replaced by a number (say, A - 1, B - 2, and so on). The word ‘breadfruit’ will appear like ‘2 1 15 2 1 2’ in this example, and the key will be the alphabet, where each letter corresponds to a number. Of course, more sophisticated rules are utilized, but the idea of the operation is roughly the same.

When there is only one key for all interlocutors, as in our case, such ciphers are referred to as symmetric. Before you may use a symmetric cipher, all interlocutors must acquire this key in order to encrypt and decode their own communications. Furthermore, it must be transmitted in an unencrypted format (after all, there is nothing to encrypt with yet). If you have to send the key over the Internet, attackers can intercept it and successfully spy on everything you've secured with it. This is not very practical.

As a result, there are encryption methods that employ two keys: private for decryption and public for message encryption (these keys are also called private and public). Both are the recipient's creations. He does not give the secret key to anyone, therefore he will not be intercepted.

The second, the public key, is intended to allow anybody to encrypt data with it, but it can only be decrypted with the accompanying private key. As a consequence, it is not frightening to send information in an unencrypted form — it poses no harm. This method of encryption is known as asymmetric.

Both the ‘lock’ and the ‘key’ (that is, public and private keys) in current encryption systems are typically huge integers, and the algorithms themselves are constructed on sophisticated mathematical processes using these numbers. Furthermore, operations must be designed in such a way that ‘turning them back’ is exceedingly difficult. As a result, having the public key will not assist someone attempting to break the cipher.

Quantum cipher cracking

What this means is that anything that is encrypted with a public key can only be decoded by its private ‘partner’, and no one else. This indicates that the private key is being investigated by potential adversaries. Because it is not sent to any location, as we have stated previously, it is not feasible to intercept it. However, in principle, one may get it from the general populace.

However, cryptographic methods are purposely intended to make it difficult to solve the challenge of acquiring a private key from a public key in a reasonable length of time. This is done by preventing the reverse engineering of public keys into private ones.

Quantum computers become useful at this point in the discussion. The simple truth is that, as a result of their design, they are capable of solving such problems significantly faster than conventional computers.

When a quantum computer is utilized, the unreasonably long amount of time needed to decipher a cipher can be reduced to a more manageable amount of time. And because of this, the very idea of utilizing a cipher that is susceptible to being broken by a quantum computer may be rendered moot in some theoretical sense.

The advent of quantum computers is imminent, and when they do arise, the world will be forever altered. Their introduction might completely change the way physics and medicine are practiced, not to mention the way that information is protected. So, how should we get ready for this?

Protection against quantum hacking

If the thought of your data being decoded and stolen by wealthy criminals using a quantum computer makes you cringe, don't worry: security experts are already planning for protection. Currently, there are some fundamental procedures in place that should protect user information from attackers.

Traditional encryption algorithms that are resistant to quantum attacks

It's difficult to believe, but we're already employing encryption methods that quantum computers can’t hack For example, despite quantum computers' increased speed, cracking the popular AES encryption used in instant messengers such as WhatsApp and Signal remains impossible. They do not pose a serious danger to many other symmetric (one-key) ciphers. we're back to the issue of distributing the key to all participants in the discourse.

Algorithms that are created expressly to thwart quantum assaults

Although no one is currently breaking asymmetric ciphers, mathematicians are actively developing new ones that are resistant to even the most powerful of quantum devices. So, by the time the bad guys get a hold of quantum computers, data defenders will almost certainly be able to strike back.

Encryption in several ways at once

Encrypting data numerous times with various methods is a useful and accessible approach. Even if attackers hack one one type of encryption, it is not guaranteed that they will be able to manage the rest.

Using quantum technologies against themselves

Quantum key transfer systems are employed for the secure usage of symmetric ciphers, which, as previously stated, are less resistant to cracking with the use of quantum computers. They do not ensure security from hackers, but they do allow you to be certain that the information was intercepted. If the encryption key is stolen along the route, you can refuse to accept it and send another one. True, this requires specialized technology, but it is very self-contained and operates in both government-backed and commercial businesses.

The entire internet will not be hacked

So, while quantum computers appear to be capable of breaking ciphers that regular computers cannot, they are not omnipotent. Furthermore, security measures are being created proactively to prevent attackers from gaining an advantage in the arms race.

So, the world's encryption is unlikely to fail all at once; rather, certain algorithms will ultimately be replaced by others, which is not always a negative thing. This is happening right now, because after all, technology is not a static industry.

As a result, it's occasionally worth investigating whatever encryption technique a certain service employs and whether the algorithm is regarded antiquated (susceptible to hacking). Indeed, supposing that the era of quantum computers has already arrived, it would be prudent to begin encrypting extremely important data meant for long-term preservation.

You want others to see your music video if you publish it on the internet. However, if your film is for corporate training, you don't want unauthorised persons to see your sensitive company information. Video encryption can keep unauthorised people from accessing your content.

Data breaches, illegal sharing and data theft are all dangers for modern businesses. To be competitive in today's world, you must rely on content security to keep your company's information safe and secure.

Encrypting your videos is one method of safeguarding your company's data. Once your video footage has been encrypted, you can safely share it with your employees, customers, partners, and prospects.

There are three ways to safeguard your videos from unwanted access: encrypting the video, protecting the video, or doing both.

What is encryption?

While encryption refers to the hiding or modifying of data, protection refers to safeguarding the file using codecs, passwords, container formats, and so on, all so that outsiders cannot access the data contained within.

However, for increased security, you can use both encryption and protection, which is the greatest solution for securing your content. In informal conversation, the term encryption can refer to encryption, protection, encoding, or any combination of the three. As a result, encryption in this context means securing your data in every way possible, which includes encryption as well as protection.

What exactly is video encryption?

The method of making your video secure from prying eyes is known as video encryption. Why should you encrypt your videos? There could be two explanations for this. The first is for personal use, and the second is for Digital Rights Management (DRM)

Personal encryption, as the name implies, is used to protect one's privacy. For example, suppose you make a film and want to share it with your relatives, mates, customers, and so on, but you don't want unwanted people to access it.

Digital Rights Management is similar in concept but more sophisticated. The various degrees of DRM are as follows:

– Software-centric video
– Adaptive streaming
– Qualitative and quantitative video streams for various price points
– Device or media-centric video
– Region-centric video

So, what exactly is the distinction between personal encryption and Digital Rights Management? Others are kept out of personal encryption except for the intended recipient. However, in the case of DRM, it either temporarily or permanently shuts people out, without human intervention and under certain conditions.

For various pricing ranges, qualitative and quantitative video feeds are available. – If you're willing to spend more money, you can obtain 4K, but if you want to save money, you'll have to settle for SD. It has an effect on the quality since it directly affects the resolution (physical data of the video stream). The higher the price, the higher the quality.

Region-centric video

Do you want to target a specific region? Perhaps you don't want the video to be seen in other areas or countries. The reasons for this type of DRM could be because you are legally prohibited from catering to other regions, or you want to influence market dynamics. In such cases, region-specific management is required.

Device or media-centric

This is done to prevent your material from playing on incompatible devices. You generate media that is limited to a specific device, such as iTunes, Kindle, or Apple TV. As such, those who do not adhere to the devices in question are unable to play it.

Software-centric video

To play some videos, you must have proper software support and/or pay a licence fee. Specific NLEs will not play certain codecs if the operating system does not support them or if the licence is not paid for. As a result, codec licensing is yet another method for controlling video consumption.

Adaptive streaming

During adaptive streaming, the video dynamically changes to the resolution and bit rate of the internet speed and/or other circumstances.

How are online videos kept secure?

The video is first encoded using conventional encryption and stored on a secure server. The video is not available for everyone to view. To view/access the movie, you must first log in to the server using a confirmed email address and password.

The video is delivered to the viewer's computer through a secure channel and may be watched using a browser that decrypts the video. The browser prevents unwanted access to other applications to see or record it. The browser also prevents the OS from storing the material on the viewer's PC. The secure connection ends as soon as the viewing is over. The data from the viewer is sent on to the content provider for targeted marketing and statistical study. You may also use this data to track down pilferages and leaks. And, if the video is accidentally downloaded, the encryption ensures that it does not play on the accessible media player.

How exactly does video encryption prevent piracy?

The "pirate" must have sufficient expertise to decrypt the encryption. To obtain a high-quality stream, pirates must pay up. And, of course, if you pay, the server will have the essential information about you.

To obtain an accessible format, the pirate must encode the encrypted stream using the software. The procedure either increases the file size or decreases the quality of the source. As the file size grows, the pirate must pay more money to transfer the data again. To detect correlations, cloud algorithms might use the uploaded material and compare it to the original stream.

Options for video encryption

When it comes to video encryption, there really are two scenarios: video at rest and video in action (streaming).

Video at rest

Here are some possibilities for videos that remain on hard drives or are downloaded to play later:

– AES encryption standard - 128, 192, or 256 bits
– Google Widevine
– Apple Fair Play for iTunes videos
– Marlin
– PMP (Protected Media Path) in Windows

Video in motion or video streaming

Some examples of video in motion or streaming video include:

– RTMFP and RTMP(E)
– HTML5 DRM standard

The Advanced Encryption Standard (AES), which has been approved by the government of the United States and is currently utilised all over the world, is the encryption method that provides the highest level of safety.

Running tasks in the background

A new mechanism for handling tasks allows you to run them in the background. For example, you can run an LDAP synchronization task and still work in Passwork. Your synchronization task will run in the background.

You can see scheduled and completed tasks on the “Tasks” page. Here you can also find the configuration instructions for your operating system.

Display a favicon in the password list

The Passwork interface has become even more user friendly and convenient. If a password has a URL, a website icon will be displayed next to its name.

Automatic favicon loading can be set up by administrators on the “Company settings” page. In this case background tasks should be set up.

Other changes:

• Automatic session termination in the mobile app and Passwork extension when API key is changed
• Removed white background in the dark theme when loading pages
• Fixed bug displaying the results of an outdated search query
• Improved validation of TOTP keys
• Fixed empty messages in Syslog
• Added login validation with UTF-8 encoding
• Added automatic LDAP host swap :\\ → ://
• Fixed errors in LDAP code related to the migration to PHP 8
• Redesigned login and registration forms

Nearly 20 years ago, the National Institute of Standards and Technology (NIST) established guidelines for secure passwords. Indeed, they are still used by many websites, portals, and other services. You’re likely familiar with these password requirements — there ought to be at least 8 characters, both capital and lowercase letters, digits, and special characters. Despite these guidelines, passwords that meet these requirements are no longer safe from modern attackers. The only thing any of us can do to improve the security of our accounts is to make sure that our passwords are lengthy, complicated, and unique for each account. Due to the strict password management requirements, this strategy is, nevertheless, laborious and intimidating for many.

The Same Password Rules Do Not Apply Today

In the modern day, password-based security is no longer seen as sufficient. Our digital world is continuously expanding, thus it is more important than ever to make sure that our data is safeguarded from cybercriminals. Cybercriminals perceive an opportunity to target people in a more sophisticated way as a result of the increasing usage of internet services. One explanation is that, although we benefit from technological improvement for our personal, social, or economic growth, cybercriminals have also benefited from the advantages of improved computer graphics cards and machine learning to enhance their attack strategies. In addition to the problem of more sophisticated cyberattacks, there are two interrelated problems with conventional password rules:

The first concern lies in our human nature — keeping track of passwords is tough

You may take a few steps as an individual to increase the security of your passwords. Start by lengthening and making your passwords more complicated. Second, create a unique password for each website you visit. The difficulty of remembering a password increases with its complexity. As a result, we frequently select passwords that are not entirely suitable yet are simple to remember. The difficulty of managing several complicated passwords for every online account leads to the frequent reuse of the same passwords across multiple platforms. As a result, a successful attacker immediately wins big.

However, the high level of password complexity necessary to maintain online safety should not be blamed; rather, it should be pointed out that we can’t improve our inadequate password management skills. Using a password manager to generate and store secure passwords is a useful solution. It is not humanly possible to manage strong passwords for all of our internet accounts without assistance, such as password managers. Because they can't recall the complicated, random sequences of letters, numbers, and special characters, the problem increases the likelihood that individuals will write down their passwords. Passwords are left exposed in digital files stored on a computer or in desk-top notes, making it simple for hackers to hack and read passwords.

The second problem is that passwords have a mathematical limit

There are only ever a finite amount of potential password combinations since a password is a mix of letters, numbers, and symbols. As a result, the best technique for breaking passwords is brute force attacks. Until the correct combination is identified and the password is broken, brute force attacks attempt all possible combinations of letters, numbers, and symbols. Theoretically, a stronger password would be one that is harder to guess due to its length, complexity, and number of possible permutations. However, attackers are now substantially more frequently exploiting Graphic Processing Units (GPUs) to break passwords. GPUs are a component of a computer's graphics card and were first designed to speed up the loading of images and movies. They now show promise for computing hashes (the method used in brute force attacks).

According to studies on password cracking times, passwords may be cracked much more quickly using sophisticated computer graphics cards. Using the most recent computer graphic cards, an 8-character password that used to take 8 hours to crack in 2018 now only takes 39 minutes (see the conclusive 2022 results in the table below). Passwords are gradually getting simpler to crack as a result of recent technical developments, which is a concerning trend. More crucial, however, is the fact that if a password has already been stolen, repeated across sites, or contains basic phrases, attackers may access your accounts right away, regardless of the complexity of the password or the attacker's graphics card.

Consider a 4-character password made up of all 26 letters in the Latin alphabet (case-insensitive) in order to visualise this mathematical example.

26^4 = 456,976 possible password combinations

The number of viable choices rises to when you include digits, uppercase and lowercase letters, and special characters.

95^4 = 81,450,625 possible password combinations

However, because the password must contain at least one special character, one number, one capital letter, and one lowercase letter, the quantity drops to

5,353,920 possible password combinations.

Nevertheless, assuming there are no password-entry security measures, this can be cracked in less than a second by a computer (such as automatic account blocking).

Increase the length and complexity of passwords

Longer or more complicated password phrases are strongly advised when creating new passwords. In this manner, potential attackers will have a harder time breaking the codes. It's crucial to take into account the popularity of the selected password combination in addition to the amount of alternative password combinations. For instance, lists of frequently used passwords or phrases, such as "qwerty," "password," or "12345," are frequently used in brute force assaults.

Therefore, the password should be completely unique or not contain any words at all. For instance, one technique would be to employ acronyms or mnemonics, such as generating a password out of the first few characters of a long text. As an illustration, consider making the password ‘Ilts@7S!’ out of the words I love to ski at Seven Springs.

Password length and complexity alone are insufficient

We are aware that adding length and complexity to passwords is the only method to increase their strength and, consequently, the safety of our accounts. The time it typically takes an attacker to break a password in 2022 using a powerful commercial computer is displayed below. This chart, which has been analysed and periodically updated since 2018, shows how quickly passwords can be broken on current machines. This pattern indicates that, despite our best efforts to create passwords that are longer and more complicated, passwords alone are no longer sufficient to meet the required internet security standards.

In conclusion, password rules increase the complexity of passwords without necessarily enhancing their security. The answer to that is to use no passwords at all. However, we’ll discuss that in part 2 of this article.

These days, locking your door and protecting your WiFi network are almost the same in terms of their importance. Without any protection, hackers may access your network and your personal information, such as your bank data, via any of your connected devices, including your video doorbell. Modern WiFi routers utilise security protocols and encryption technologies to mask your sensitive data so that you can protect yourself. In order to select the proper security settings for your WiFi network, you must understand the differences between WEP, WPA, WPA2, and WPA3.

WiFi Encryption: What is it?

Nowadays, the majority of WiFi routers encrypt all the data sent by your connected devices, including your computer, smartphone, or smart home appliances. As a result, nobody else will be able to access any of your personal information without the decryption key since it will convert all of your data into "cipher text."

An encryption protocol can be compared to a combination lock. To unlock your data and decode it into plain text, you need the appropriate combination.

The WiFi Alliance, a nonprofit organisation that holds the Wi-Fi trademark, has certified all WiFi protocols. There have been four distinct encryption systems throughout the years: WEP, WPA, WPA2, and most recently, WPA3.

WEP

The WiFi Alliance approved the first wireless security standard, called WEP (Wired Equivalent Privacy), in 1999. The WEP standard was initially intended to offer security that was comparable to that of a wired connection, however several security holes were found over time.

WEP really offers "little to no protection, since WEP can be broken using publicly accessible tools," according to the FBI. The WiFi Alliance formally abolished WEP in 2004 as a result of these security concerns. It’s crucial to remember that utilising WEP is still preferable to employing no security mechanisms at all.

WPA

The WPA (WiFi Protected Access) standard was introduced in 2003 as a stopgap measure to take the place of the WEP standard. WPA employs Temporal Key Integrity Protocol (TKIP) to dynamically produce a different key for each data packet delivered, in contrast to WEP, which uses the same key for each authorised system.

The WiFi Alliance deprecated the WPA protocol in 2015 because it "no longer provides the level of security required to safeguard consumer or corporate WiFi networks" due to a range of uncovered security weaknesses.

WPA-PSK

A streamlined WiFi security protocol called WPA-PSK (Pre-Shared Key) was created for residential networks. Similar to WEP, it employs a static key to make things simpler, but the key automatically changes on a regular basis to stop hackers from breaking into your network.

WPA2

When we compare WPA with WPA2 (WiFi Protected Access Version 2), we can observe a substantial increase in security. WPA2, which was introduced in 2006, is identical to WPA but replaces TKIP with the more powerful Advanced Encryption System (AES).

The US government uses the same encryption standard, AES, to safeguard secret materials. With WPA-AES, relatively few security holes have been found, and the majority of them may be avoided through the use of a strong password.

Since WPA2 certification became required in 2006, any router produced after that year must support WPA2. When you connect an older device, WPA2 routers will still default to WEP, so be careful to turn off WEP on your router to close these security gaps.

WPA3

In 2018, the WiFi Alliance certified WPA3, the newest WiFi security technology. WPA3, the most recent network security protocol, enhances the security characteristics of WPA2 by introducing new ones.

For instance, WPA3 verifies authentication via a "handshake" between your network and any of your wireless devices. A gadget only allows someone to guess the WiFi password once if it is offline. This safeguard makes sure that the user must be able to view your router directly.

Even if WPA3-certified items are becoming more widely available, not everyone will have access to them. If your router is outdated, you may need to replace it or wait in the hope that your manufacturer releases an update that enables WPA3 usage.

What WiFi security protocol is the best?

The WiFi Alliance advises using WPA3 as your wireless security protocol if your router is compatible with it. However, if you have older devices connected to your network since WPA3 is still so new, you might need to utilise WPA2.

• WPA3-Personal: The best security setting for home WiFi networks
• WPA3-Enterprise: The best security setting for businesses
• WPA2 (AES): The second-best security setting, available on more routers
• WPA/WPA2-PSK (TKIP/AES): The best security setting for networks with older devices because it enables you to use both WPA and WPA2, but it is not available on most routers
• WPA2-PSK (TKIP): Still usable, but it only provides you with minimal security
• WPA-PSK (AES): An updated version of WPA that replaces TKIP with AES, but you should only use this setting if there are no better options available
• WPA-PSK (TKIP): No longer considered secure
• WEP 128: Risky
• WEP 64: Highly risky, but better than having no security
• Open network: No security at all

When you get a new WiFi router, the first thing you should do is create a strong, unique password for your WiFi network. The WiFi Alliance recommends that you use a password that is at least 8 characters long and contains letters, numbers, and special characters.

After you create a password, the WiFi Alliance also suggests that you change it at least once a year. You should also change your router’s login credentials, install an antivirus program, and update your router’s firmware.

With iCloud, you can recover data from any iOS device in just seven steps.

Although Apple products are known for their high performance and durability, problems with your iPhone, iPad, or Apple Watch can arise at any time. Fortunately, backing up Apple devices to iCloud is simple. However, just like with the best data recovery tools, you'll need to know how to restore a backup from iCloud in case something goes wrong.

We have thus provided these seven simple steps to help you reset your iOS device using an iCloud backup. Although iCloud is one of the better cloud storage options as one can open it in a new tab, it has one significant drawback: you must wipe your device completely before uploading a backup. If you require a fix for this problem, skip to step 7 of this article.

How to restore an iCloud backup: Setting up

Before restoring a device, you must configure iCloud's backup feature because there won't be anything to restore otherwise.

You must configure the iCloud backup before you may restore your iOS device from a backup. The best time to do this is when you first set up your device, but you can do it whenever you choose.

Go to the Settings app and tap on your name at the top to get started. Then, select "iCloud" and then "Backup" from the list. Ensure that "Backup" is turned on. iCloud will automatically back up your data when your device is locked, plugged in, and connected to WiFi after backup has been enabled.

To manually initiate an iCloud backup, go to Settings > iCloud > Backup and press "Back Up Now." Your Apple device can always be reset to the most recent iCloud backup if you encounter a technical problem or need to recover lost data.

Remember that the complimentary iCloud account that comes with your Apple ID only offers 5GB of storage space. The majority of Apple’s products have much more internal capacity than that. For instance, the iPhone 13 has at least 128GB of internal storage.

Consider eliminating any unnecessary files or upgrading to iCloud+, which starts at $0.99 per month for 50GB of storage, if you try to backup your smartphone to iCloud and discover that your iCloud storage is full.

Step 1: Get ready for a factory reset on your device

You must carry out a factory reset prior to restoring your device from a backup using the standard Apple procedure. This implies that you must delete all of the content that is currently on your device. You can work around this by utilising third-party software if you don't want to perform a reset. To learn how to restore from a backup using third-party software, skip to step 7.

Examine your notes, files, images, and any other apps you think may contain crucial information. After you complete the reset, anything that was added since your most recent backup will be irretrievably gone.

Step 1b (Optional): Disconnect your gadget (Apple Watch only)

Resetting an Apple Watch entails an extra step.

You must unpair your Apple Watch from your iPhone as a separate step before moving on to step 2 if you're resetting an Apple Watch.

Open the Apple Watch app on your iPhone and go to My Watch > All Watches to get started. To unpair an Apple Watch, tap the details button next to the watch you wish to do so. The system will prompt you to decide whether to keep or cancel your mobile plan. Keep it, because you will soon restore it from a backup.

Before continuing to the next step, tap once more to confirm, then enter your Apple ID password to finish the unpairing procedure.

Step 2: Reset your device

Go to Settings > General > Transfer or Reset [Device] once you are certain that nothing crucial will be lost. To start the factory reset, tap "Erase All Content and Settings" after that. You will now be required to enter your Apple ID password or device passcode.

Wait for the reset to finish after entering the passcode. Depending on how much stuff is already on your device, this can take a while. When you see the ‘Hello’ screen from when you first set up your iOS device, you will know the reset was completed.

Step 3: Configure and turn on your gadget

After a reset, you'll need to perform an initial installation once more.

You will need to go through the basic setup procedures the same way you did when you originally acquired your device because your iOS installation is now essentially brand new. Tap the ‘Hello’ screen to get started, then select your language.

To configure your device and connect it to the internet via WiFi or cellular data, simply follow the onscreen instructions. Set up your passcode, Face ID, and Touch ID lastly. Not all Apple devices will have all of these functions, so keep that in mind. You are currently prepared to restore your iCloud backup.

Step 4: Restore iCloud

You will have a number of options to restore your data on the following screen. "Restore from iCloud Backup" is the first choice; tap it. iCloud will now ask you to log in with your Apple ID.

You will get a list of available backups after logging in. Unless you want to backdate your device to a certain day and time, pick the most recent. iOS might be telling you that you need to execute an upgrade right now. If this happens, let the update finish installing before trying to restore your device.

Your files, notes, and photographs will all be restored at this time. Restoring your apps is the subsequent step.

Step 5: Restore your apps

Once you're logged in, restoring previously purchased apps is simple:

Log in with your Apple ID to recover apps that have been purchased. While your device downloads all of the apps linked to that ID, stay connected to WiFi. If you have several Apple IDs, sign into each one separately and wait for the corresponding apps to download.

Depending on how many apps you have, this stage may take some time, so be prepared to wait.

Step 6: Finish the setup procedure

There are a few last-minute adjustments to do before your device is ready for use, once you have finished restoring your data and applications. To continue configuring your iOS device, follow the on-screen instructions.

You will be prompted to choose whether you want iOS upgrades to launch automatically or manually as well as if you want to share data with Apple for development purposes.

Additionally, you'll be prompted to configure default features like Screen Time, Apple Pay, and Siri. Once you've finished, a big congratulations is in order! Your iOS device has been fully restored from an iCloud backup.

Step 7 (Optional): Restore your smartphone using third-party software without performing a reset

Using an iCloud backup to restore your iOS device can be a laborious and time-consuming operation. It can take hours to perform a factory reset, download the backup, download your apps again, and, possibly, re-update iOS.

Going through the entire reset and restore process can be a major inconvenience if you just lost a tiny amount of data, such as a single image or a few texts. Fortunately, certain third-party applications, like EaseUS and MobiMover, let you selectively restore a small amount of data from an iCloud backup file without performing a complete reset.

Download the reset program of your choice to get started. Keep in mind that the majority of third-party reset software is not free, but it does provide a free trial that allows only you to download a certain amount of data. If this is an isolated incident, you can recover a few files using the trial at no cost.

How to recover an iCloud backup: Synopsis

You now understand how to backup an iOS device to iCloud and restore your device using that backup. One of the numerous advantages of this robust cloud storage service is the ability to use iCloud to backup your gadgets.

Every day, people all over the world are spending more and more of their waking hours online. In addition, we're increasingly using our mobile devices for much of our internet activity. The banking industry is unquestionably following suit.

More than seventy percent of Americans conduct some or all of their banking transactions online. Mobile devices now account for more than half of all website traffic, and financial institutions are not far behind.

How safe is mobile banking?

Of course, popular things aren't always safe. Passwords are a prime example. Convenience is a major factor in the migration to the online world and mobile banking. Many people simply accept the new reality without weighing up the pros and cons.

In this article, we'll look at the dangers of mobile banking and what you can do to keep your information safe.

Is mobile banking security at risk?

The most secure method when it comes to banking is, without a doubt, in-person endeavours. But, even if you are paranoid about being hacked, you shouldn't abandon convenience because of it. You've already taken the first step in safeguarding yourself if you're aware of the dangers of online and mobile banking, but don’t be paranoid.

If you're using a web browser on your PC or a mobile banking app on your phone, you face the same basic hazards. However, the vulnerabilities of various devices vary. Moreover, different apps necessitate the possession of a diverse range of hacking capabilities.

People who are increasingly relying on their smartphones rather than PCs may want to consider the following:

When it comes to security, is online banking more reliable than mobile banking?

Indeed, this is a valid question. The more detailed response necessitates additional thought. Traditional PCs are still the primary target of most viruses. Hackers must focus on more precise targets than just a web browser in order to target mobile malware, which is rare.

Now that's wonderful news, right? The bad news is that research conducted by security experts on mobile banking apps has revealed that nearly all of them contain at least one vulnerability. The problem is that these are rarely high-level flaws, however, if you're careful, you can escape a lot of trouble.

Keeping your device safe is an important part of exercising caution. While your desktop computer is likely to stay put, your phone is more likely to follow you wherever you go. As a result, it's more likely to end up in the wrong hands. If you’re new to the smartphone era, this is an issue. It's still not a good reason to give up on mobile banking, however.

The best ways to keep your online banking information safe

Are you still unsure of what those safeguards are? We've compiled a list of our top five picks. All except the most serious threats should be covered by these measures. If you're using mobile networks or your home internet, these tools should enable you to keep your activity safe at all times.

Use a VPN

In order to protect your mobile banking, you should use a virtual private network (VPN). Hackers can't see what you're doing if you hide your IP address and avoid internet tracking.

It doesn't matter if you're using public Wi-Fi or not. Public networks, by themselves, are extremely unsafe. A top-rated VPN like ExpressVPN or NordVPN, on the other hand, bring the security of your home internet connection with you wherever and whenever you travel. You can't link your phone data to your online banking activity because there is a virtual barrier between them.

If you’re not willing to sacrifice a bit of extra time for added security, this isn't for you. The convenience of using online banking can be compromised as a result. If you're using a VPN, your bank won’t know that you're trying to get into your own account. There will be an additional stage in the verification of your identity because of this.

Keep your devices safe!

Security risks in online banking aren't always posed by external sources such as the internet. Defending against direct device breaches is the initial step. Keeping your phone in a familiar location and making sure it's safe even if it gets lost is therefore a must!

In other words, the best way to unlock your home screen is by using a pin or facial recognition software. If you don't want apps and websites to save your passwords, you should log out of them and tell them not to do so. You'll have more time to notify your bank if your phone is stolen if you have more security measures in place.

Use only long, complex passwords

The majority of websites demand that you choose a complex password when you set up or update your account. However, you should be aware of the following guidelines:

• Make use of both capital and lowercase letters, digits, and other characters to enhance complexity;
• Never use the same password on more than one website, and make sure it's difficult to decipher. A strong password can be generated with the aid of specialised software.

As a result, most individuals wonder, "How am I supposed to remember so many strong passwords?" We're not counting on you to become a walking, talking, thinking machine. There is a common misconception that you should never write down your passwords. Passwords should be kept secure and separate from the devices on which they are used.

Keeping your online banking password in a separate location from your phone is the best way to keep it safe. Do not reveal what this location is used for.

Installing a password manager, on the other hand, allows you to store unique passwords for each website you visit. After that, all you have to remember is one secure password and the manager may log in on your behalf to all of your other accounts. And remember, that’s what we offer at Passwork.

Check your bank's security practices

Your bank's website should have instructions on how to keep your personal data safe. We strongly suggest that you take the time to read it. Even if you don't comprehend all that they say, you should be able to get an idea of whether or not their methods are secure.

The padlock icon, which indicates that the website is correctly encrypted, is one of the most obvious things to look for. Two-factor authentication is another option that can be used. Even if you don't feel the need for it, you should turn it on just in case. Each time you log in, you must either answer a security question or provide a one-time security code.

Your bank's dedication to security is demonstrated by measures such as these. It's also an indication of how safe their applications are. If your bank doesn't prioritise security, it's time to find a new one. It's likely that a bank that doesn't care about customer service isn't concerned about security either.

Recognize scams and phishing attempts, and avoid them at all costs

No matter how secure your bank is, they will never ask for your account information. This is almost probably a phishing attempt if you receive such a message.

In order to deceive people into disclosing personal information, hackers frequently send emails that appear to be from legitimate organisations. Fake websites may be used to trick you into clicking on dangerous links.

You’re sure to fall for this kind of scam if you don’t know what to look for. However, you can easily avoid it by teaching yourself to be sceptical of all unsolicited texts. Any notification you receive from your bank should be checked against the bank's website if you are unsure about it.

Conclusion

The better informed you are about internet safety, the better off you'll be in the long run.

Precautions like using a secure VPN and using strong passwords will help you stay safe online while also teaching you how to spot potential risks. That's why ExpressVPN is our top recommendation for online banking security.

Using our advice, you should be able to begin using mobile banking safely. You'll soon become used to the convenience of mobile banking if you're vigilant.

In order to keep its customers' devices safe, both Apple and Android employ a variety of safeguards. A group of IT security specialists from around the world looked at the effectiveness of these tools, and that’s what we’re going to be discussing today.

Indeed, IT security researchers from Germany and the US conducted a study into how mobile phone users pick their PINs and how they may be persuaded to choose a more secure number combination. According to the researchers, six-digit PINs are no more secure than four-digit ones in terms of protection. Apple's usage of a "blacklist" to keep track of frequent PINs might be improved, and it would make more sense to deploy one on Android devices as well, they found.

Dr. Maximilian Golla of the Max Planck Institute for Security and Privacy in Bochum and Professor Adam Aviv of the George Washington University in the United States collaborated on the study with Philipp Markert, Daniel Bailey, and Professor Markus Dürmuth from the Horst Görtz Institute for IT Security at Ruhr-Universität Bochum. The findings will be presented at the IEEE Symposium on Security and Privacy in San Francisco in May 2020, according to the researchers. The paper's preprint may be downloaded at arxiv.org.

What do users really need?

In the study, researchers had participants create either four- or six-digit PINs on Apple and Android smartphones and then analysed how simple it was to guess them afterwards. It was considered that the assailant had no idea who the victim was or cared about unlocking his or her phone. As a result, the most effective method of attack is to start with the most likely PINs.

PINs might be chosen at random by some research participants. Only PINs that were not on a blacklist were available to the rest of the population. One of the PINs that had been banned had a warning that this combination of digits was simple to guess.

IT security specialists utilised a variety of common passcode blocklists in the experiment, including the official list from Apple. The experiment involved a machine that tested all conceivable PIN combinations on an iPhone. The specialists also compiled their own lists which were tested too.

Is there any benefit in using a six-digit PIN over a four-digit PIN?

Six-digit PINs have been shown to be no more secure than four-digit ones. As Philipp Markert explains, "Mathematically speaking, of course, there is a tremendous difference." Ten thousand four-digit PINs and one million six-digit PINs may be generated, respectively. Philipp Markert also notes that consumers favour particular combinations of PINs, such as 123456 and 654321. This implies that the six-digit codes are not utilised to their full capacity by consumers. PIN security is something people don't seem to grasp instinctively, according to Markus Dürmuth.

Manufacturers restrict the amount of PIN entry tries, thus, a well-chosen four-digit PIN is safe. After 10 unsuccessful attempts to enter the pass code, Apple permanently locks the device. On an Android phone, several codes cannot be input in rapid succession. Philipp Markert points out that "in eleven hours, 100 number combinations may be examined."

Do blocklists matter?

Researchers discovered 274 four-digit PINs that were on Apple’s blocklist. This list is used as a mechanism for improving PIN selection, as Apple iOS users are shown the warning "This PIN Can Be Easily Guessed" with a choice to "Use Anyway" or "Change PIN." It’s effectively a list of very easily-guessed pins. Maximilian Golla says, "Since iPhone users only have 10 chances to guess the PIN, the blocklist does not make it any more secure." Using a blocklist for Android devices would make more sense, according to the researchers, because attackers may test out a wider range of PINs.

According to the study, the optimum blocklist for four-digit PINs should contain around 1,000 entries and varies somewhat from the list now utilised by Apple. Four-digit PINs like 1234, 0000, 2580 (the numbers show vertically below each other on the numeric keypad), 1111, and 5555 were found to be the most popular.

Now, iPhone users can choose to disregard the alert that they have entered a commonly used PIN, as we have seen. Because of this, the device does not reliably prevent entries on the blacklist from being chosen. The IT security professionals also took a closer look at this element as part of their research. It was up to the individual test participants to decide whether or not to enter a new PIN after receiving the warning. Those who were not on the list had to create a new PIN for themselves. Both groups' PINs were equally difficult to guess on average.

Pattern locks are less secure

Four and six-digit PINs were shown to be more secure than pattern locks, but not as safe as passwords.

The simpler the pattern is, the easier it is for lurkers to copy it, if they are watching over your shoulder. In fact, research found that lurkers were successful in recreating the swipe pattern 64.2% of the time after looking at it once. Of course, with multiple observations, that success rate rises.

According to the study, these are the most frequently used PINs:

• Four-digit PINs of the following kinds: 1234, 0000, 2580, 1111, 5555, 5683, 0852, 2222, 1212
  
• Six-digit PINs of the following kinds: 123456, 654321, 111111, 000000, 123123, 666666, 121212, 112233, 789456, 159753

So, don’t forget to double check that your PIN is not on the list above. If you’re interested in evaluating your password security, we strongly recommend checking them against the security.org password checker.

Additionally, you might find the password checker by Experte to be a valuable resource. It estimates how long a computer would need to crack your password and checks if it has been exposed in any data breaches. It also provides actionable suggestions for strengthening your password, helping users create more secure credentials. Both tools evaluate each password based on key factors such as:

• Its number of characters: The password should have at least eight to 10 characters, but 16 to 20 characters is ideal.
• Combinations: The password should include a combination of letters, numbers, and symbols rather than taking the form of a phrase. Each character has an associated numerical value, and these characters are summed to create a grand total.
• Uniqueness: The password shouldn’t be repetitive in terms of its characters, with unique combinations used instead.
• Data leak check: In addition to evaluating the strength of the password, this tool checks whether the password has appeared in any known data breaches, which is crucial for maintaining your security.

Using both tools can give you a comprehensive overview of your password security and help you make necessary adjustments to protect your accounts effectively.

Backing up data is critical to ensuring system integrity, but if done incorrectly, it can exacerbate already-existing security issues. Fortunately, there are a number of best practices that can be followed.

In order to keep your data safe and secure, you need to have regular data backups. However, these backups are often the source of many security problems. In fact, a large number of security breaches can be traced back to the mismanagement of data backups. A lack of adequate data backup controls is evident in the headlines and security surveys that are published. There's nothing wrong with using best practices when developing an enterprise data backup strategy.

Millions of sensitive business records have been compromised in backup-related mistakes over the last few years, according to recent reports. Indeed, these are just the incidents that have been publicly reported. Confidential information, including intellectual property, is no less vulnerable to data backup-related breaches than other types of sensitive data. Without a solid back-up plan in place when things go wrong, security is the first thing on the shark’s menu.

As long as there is a process for replicating sensitive data, many storage professionals believe that their organisation is safe. However, this is only half of the battle. A new set of dangers arises from what can be done with data backups, which are often overlooked. Because of this, it is essential to incorporate secure data backup guidelines into the overall enterprise information security strategy.

Here are 10 ways to keep your data backups safe and secure from threats like ransomware, malicious insiders, and external hackers, both locally and in the cloud:

Make sure you have a backup plan in place

It is important to make sure your security policies include backup systems. Access control, system monitoring, and malware protection all have a direct impact on data backups.

Incorporate backup systems into your disaster recovery plan

Your disaster recovery and incident response plans should include a backup of your computer files and other important information. A ransomware outbreak, an employee break-in, or an environmental event such as a flood or hurricane can all compromise or destroy a company's data backups. If you don't have a plan in place for what to do if and when the time comes, your backups could be harmed.

In order to protect data backups, restrict access to them

Only those who need to be involved in the backup process should be given access rights. Software and data backups are no exception here either. Systems that provide backup access, whether on-premises or in the cloud, should not be undervalued.

Consider a variety of backup options

Keep your backups in a different location, such as a different building. Your data centre and your backups could be wiped out in one fell swoop if a natural disaster, a fire, or some other rare, but impactful, incident occurs.

Protect data backups from unauthorised access

Backing up to NAS, external hard drives, or tapes is fine as long as access to those locations can be tightly controlled. Your backup files are just as important as your computer's hard drive. SOC audit reports, independent security assessments, or your own investigations may be able to confirm this.

Ensure the safety of all backup media devices

Some backups are still kept on portable drives, tapes, and other media, despite the widespread use of hard disks and solid-state drives. Fireproof and media-rated safes should be used in these situations. One of the most common places to keep backups is in a “fireproof,” but paper-only safe. A standard fireproof safe only serves to provide a false sense of security for backup media such as tapes, optical disks, and magnetic drives, which have lower burning/melting points than paper.

Check out the security measures in place for your vendors

Find out what security measures your data centre, cloud, and courier service providers are using to keep backups safe. Despite the fact that lawyers appreciate well-drafted contracts, they are not always sufficient. As a fallback measure, contracts can help protect sensitive data, but they won't stop it from being exposed in the first place. Check to see if security measures are in place as part of vendor management initiatives.

Ensure the security of your network

Backups should be stored on a separate file system or cloud storage service that is located on a separate network. Ransomware-related risks can be minimized by using unique login credentials that are not part of the enterprise directory service. The use of two-factor authentication can increase the security of your backup system.

Encrypt backups as a top priority

Whenever possible, encrypt your backups. The same is true for backup media and files, which must be encrypted with strong passphrases or other centrally managed encryption technology if they are to be taken outside the premises at any point in time. Encryption is an excellent final layer of defence when implemented and managed correctly. It's reassuring to know that even if your backups are corrupted or destroyed, you won't be able to access them. This is especially useful when it comes to meeting compliance and notification requirements in the event of a data breach.

Ensure that all of your data is backed up and tested frequently

These data backup flaws are likely to exist within your business. Before you're hit by a ransomware attack or data destruction, it's a good idea to find out where your vulnerabilities lie. Hire an unbiased third party to find the holes in your data backup processes and systems on a regular basis or look for them yourself. In the end, it's the little issues that aren't so obvious at first that can be the most difficult to deal with.

As a kid, I was enthralled by science fiction films like 2001: A Space Odyssey, The Fifth Element, and Minority Report, hoping that the wonderful technology shown in these films — facial recognition, artificial intelligence, gesture controls, and flying cars — would one day become a reality. Today, we have access to most of these technologies, with the exception of flying automobiles, owing to the likes of Apple.

One of these emerging technologies is facial recognition. Face ID, Apple's replacement for Touch ID's fingerprint sensor, has been available to consumers since the release of the iPhone X. However, how secure is Face ID when we compare it to Touch ID, despite how nice, convenient, and futuristic it seems? What additional security or privacy concerns does it raise?

It's important to keep two things in mind while evaluating the security and effectiveness of various forms of authentication, including biometrics:

• An attacker can guess, duplicate, steal or fake the authentication factor with relative ease;
• It is not as secure as two-factor authentication!

And here’s why…

The inner workings of Face ID

Facial-recognition systems have always been weak authentication points because they were either simple to fool or highly sensitive to ambient conditions.

In addition to detecting movements in 2D video, Face ID uses a method called ‘structured light’ to map out 3D scenes. Taking this further, "TrueDepth" uses a structured IR light (30,000 dots) to create a 3D representation of your face by measuring the depth of various spots.

Now, this increases the identification accuracy and safety of Face ID dramatically. An old-fashioned photo or video will not mislead a 3D facial scanner, unlike in the past.

For Face ID to work, Apple advises you to stare straight into the phone’s camera. This means that the system is also looking for any movement of the eye or the pupil. The skin and texture cues seen in certain facial-recognition algorithms can also help increase recognition accuracy. But, this is not how Face ID works.

There is no such thing as impenetrable technology. When researchers used publicly available photos and the technology of photogrammetry, they were able to generate 3D representations of a person's face that were quite realistic (specifically, stereophotogrammetry). We shouldn't be surprised if researchers and attackers uncover additional ways to fool Apple's Face ID mechanism in the future.

In spite of all the Face ID joke memes and the botched log-in at Apple's launch event, I feel that Face ID has been built quite effectively. This facial-recognition system appears to be more secure than many others because of its underlying technology, I believe. Even a 3D-printed face isn't enough to pose a threat, you’d need to put in a tremendous amount of work to do so.

A digital copy of your face

The digital form of an authentication factor is a second security risk for authentication systems. To put it another way, can an attacker obtain a digital replica of your login credentials and log in as you?

As far as the numbers are concerned, Apple appears to have done an excellent job of protecting this information on paper. In Apple's words, the model of your face is never saved outside of your iPhone X. No network or cloud storage is used for this data. On an iPhone, a "secure enclave" is where the Face ID data is saved, much like how your Touch ID fingerprints are stored.

Security and cryptography operations are handled by a distinct processor in Apple's newest SOC processors, the secure enclave processor (SEP). This processor is separate from the main processor and runs on its own operating system.

It is possible to store a digital key (such as a Face ID model) in your phone's SEP, but the main CPU does not view or manage it. Only the "outcomes" of the key's activities are received. Your face isn't shown to the operating system; it just receives a "matched" or "not matched" response from an encrypted area of your device. Simply put, Apple has created a method that makes it extremely difficult for attackers to get your Face ID data.

Is it enough?

Researchers and hackers will eventually find a way to get around Face ID's security measures. When it comes down to it, no one form of verification can ever be completely secure. We can use something we already have (passwords) or something we know (tokens or certificates) to authenticate (biometrics). The concern is that these tokens may be stolen, guessed, or replicated in a variety of ways.

Biometrics, such as Touch ID and Face ID, have grown increasingly popular since they are considerably easier to use than passwords and provide a reasonable level of protection. A lengthy series of random characters and numbers is simply too difficult for the ordinary human to recall.

But we're falling into the same trap, as well. All authentication methods have flaws, including biometrics. We will one day learn that biometrics like Face ID are no better than passwords.

That's why multifactor authentication is the only option that is genuinely safe. We need to combine two or more parameters instead of using them on their own. Someone could definitely make a convincing clone of your face with enough time and effort, but what if your phone or bank account demanded that you log in with both your face and your password? That would make it a million times more difficult to decipher.

It's time to stop arguing over which authentication method is more secure: Face ID vs. Touch ID; certificates vs. passwords; or a combination of both. Face ID is a solid piece of hardware, but it's vulnerable to hacking if you don't use it in conjunction with anything else.

The storage of data is the single most significant factor to consider when it comes to the safety of mobile devices. It's true that malware and viruses are capable of infecting operating systems, which will require you to spend time and effort wiping out and reinstalling everything following a security breach. Another possibility is that actual computers could be taken, leaving you with the burden of replacing the system along with the associated costs and hassles. However, the actual worth of practically every company's digital cache is its data, which includes personal details, trade secrets, confidential information, and private chats; the chance that this data will fall into the wrong hands significantly outweighs any other issue regarding mobile security.

It can be tough to keep your data secure on all fronts, but solid-state drives (SSDs), which have intrinsic performance advantages, can make this work easier and more efficient by supporting encryption. SSDs also have other inherent advantages.

Why is encryption necessary to ensure the safety of data?

Encryption is the most important component of a secure storage system. Many businesses operate under the assumption that a device containing sensitive data would, at some point, be misplaced or stolen. The answer, then, is not to concentrate all of your energy on keeping track of physical devices or the components of their drives; rather, the thing that is most important is to preserve the real data that is stored on them. In fact, the cost of lost data or data that has been compromised might be significantly higher than the cost of a lost machine.

The process of hiding information by putting it through a series of complicated mathematical operations is referred to as encryption. After encryption, reverting back to the earlier version of the data and undoing the process that was just performed requires the use of a coded phrase known as a ‘key’. Therefore, even if the storage device that contains the data is misplaced or stolen, the data will still be unreadable; at least, it will be unreadable without the key.

There is unquestionably a great deal more to the mathematics behind encryption, such as the number of times the encryption scheme is run, the length of the key, and a variety of other considerations. The more complicated an encryption method is, the more difficult it is to read and write data as well as use the computer's processing power. This might cause the processing speed of the computer to become increasingly sluggish. This is where solid-state drives (SSDs) shine thanks to their naturally faster performance. Calculations necessary for the encryption and decryption process can take place significantly more quickly when the data can be written to or read from the drive at a higher rate.

Encryption and solid-state drives: safety and speed

There are two approaches that can be taken to accomplish encryption. One method involves using software, in which case the mathematics required for decryption and encryption is handled by the primary processor of a computer. The second method includes what is known as "delegating" the encryption process to the drive's hardware so that the storage device may do the necessary mathematical operations on its own. The disk then provides the host CPU and memory with newly decrypted data in order to avoid imposing a "performance tax," also known as a lag, on the primary components of the system.

The server-class solid-state drives (SSDs) produced by Samsung are equipped with options for full disk encryption built right into the hardware. This makes protecting company data as easy as checking a box and entering a key. Typically, this entails the drive storing a copy of the decryption key in a protected area within the drive controller circuitry itself, and then encrypting that key with another key that is provided at boot time by the user, such as a multifactor PIN or passcode. This allows the user to access the drive without having to remember multiple passwords or PINs.

What outcomes are possible in the event that computers are taken during a break-in? Would anyone else have access to the information you provide? At boot time, the information would be safe to access if it were encrypted with hardware as long as the key, which is retained by the user, was not disclosed.

Maintaining safety without sacrificing speed

Doesn't the use of encryption make things slower? The mathematics that underlies encryption does take up resources, and the more data you have, the faster your drive needs to read and write, which in turn requires more complicated mathematics. This effect is typically most evident when we consider spinning material that was produced in the past. Users are able to continue being productive and have the peace of mind that the sensitive data they are accessing will be kept secure at all times thanks to the faster performance of solid-state media, which helps to reduce the impact of the encryption’s "performance penalty."

Almost everything that can be connected to via a network can be also hacked. But what about cars? Can they be hacked? If so, how much time do criminals have to spend on it?

In fact, hackers are able to shut off your engine while you’re driving, control your steering or brakes, and even open and close your doors and boot. As a result, driving a hacked car can be pretty dangerous.

Finding a hole in your car's software is all it takes for someone to compromise the system. It isn't always that difficult for hackers to find a means to get into your car, even though it could take some time. A committed hacker can enter a reasonably sophisticated system with enough time. According to the research of Upstream — a car cybersecurity organization — by 2025, more than 86% of cars will be connected to the global network. ‘Connected’ refers to the sharing of data among servers, applications, phones, etc. Because of this connectivity, there are several ways that automobiles can be compromised.

What damage can hackers do if they hack your car?

There are multiple ways criminals can hack your car. First of all, the brake pedal and engine are vulnerable. Although your brake pedal is within your control, the onboard computer's microprocessors are what actually cause your brakes to function. Your brakes can be disabled and the engine can even be stopped by hackers who get access to your onboard computer.

Hackers also could interfere with the movement of the car using wipers, heaters, conditioners, or radio. Each of these options could be controlled remotely and used to distract the driver. Although windshield cleaning fluid is helpful, it’s more of a burden when it’s released repeatedly or abruptly. If that’s the case, it might endanger your visibility. Your windshield wipers and this system are both hackable. The same can be said for heating or conditioner systems. They are useful until they can be used to harm you.

Another way of hacking can be performed by unscrupulous repair shops. The majority of initial diagnosis is done by onboard vehicle diagnostics equipment. However, dishonest businesses may trick your diagnostics system into suggesting that you need repairs that aren't actually necessary. This is an easy way for them to earn money. Thus, it’s important to use services that are reliable.

Hackers can also use a car’s interconnected system to impact one’s car safety and its correct operation. This could, for example, lead to forced acceleration. When a car is driven or reaches a given speed, power locks frequently contain functions like automatic locking. Such integrated systems in cars make them susceptible to issues like power locks being overridden to compel an acceleration.

It’s also possible to extend the key fob range to gain physical access to the car. Modern wireless key fobs open automobile doors when the owner is nearby. Thieves who aren’t focused on harming the car owner, but rather looking to steal the car can also exploit the functionality of the key fob and increase its range using radio repeaters. It allows one to unlock the car from up to 30 feet away.

Moreover, if hackers break into your car’s entire system, they could gain your private information, especially if the car is equipped with a GPS telematics system. This data could be misused to invade your privacy and possibly to learn where you live, work, or send your children to school. The serious threat is presented by the connection between your car and your smartphone. Some advanced hackers might be more interested in your connected mobile phone than the automobile’s system. Your information is in danger if they manage to get access to the system in your car and locate the mobile device that is connected to it. The connected smartphone is a direct source of your bank credentials, passwords, and other sensitive data.

Will your car be hacked?

Nowadays, almost every car is susceptible to being hacked. But, talking about chances that you will be impacted by car hacking, it is unlikely you'll experience any issues with hacking at this stage. In any case, it’s better to be safe than sorry. Due to the lack of financial benefit, most hackers prefer not to enter this sphere, with the exception of car thieves who use elements of hacking to neutralize the car’s alarm and relevant security systems.

Car hackers frequently do this for amusement or malicious intent. Very few hackers in the real world have targeted automobiles. Instead, the majority of vehicle hacks are either theoretical or carried out by research teams looking to find weaknesses in the car’s protection. Most car hacks are difficult for average hackers to execute since they typically call for a great deal of knowledge, equipment, and sometimes even physical access to the vehicle itself. However, vehicle makers are still working to develop defenses to shield their products from cyber harm. All due to the potential possibility of hacking attempts. More and more vehicles become connection-available, smart, and independent, so it may lead to an increase in car hacks in the future.

How can you protect your car?

Currently, hackers aren't really interested in your car. However, the situation may change. Hackers may become more interested in and adept at hacking cars as they become aware of their ability to kidnap automobile owners, steal their data, and carry out nefarious deeds like larceny. There are some easy steps that should be done by every car owner to protect their privacy and security.

First of all, do not program your home address into your GPS system. While having a GPS may be handy, car thieves and hackers can use it to locate your home location.

Then, it’s necessary to limit wireless systems connected to your vehicle. You are most in danger from such technologies, as wireless or remote systems are frequently operated online and are more susceptible to hackers than many other systems.

And the last, but not the least piece of advice, use reputable shops, as anyone who gets physical access to your car and is computer savvy can wreak havoc on it. Therefore, when you leave your automobile in a shop, whether it’s for minutes, hours, or days, you run the risk of someone hacking it to make it seem as though you need repairs that aren't actually required.

Whenever the word ‘cybersecurity’ appears, the word ‘password’ springs to mind in parallel. People use them everywhere, from mobile phone locks to the protection of personal and state data stored on individual devices or websites. Everyone knows that a strong and secure password is able to save our sensitive information, however, cybercriminals have invented a huge variety of methods to hack our passwords in order to compromise us. So, modern problems require modern solutions. Now, there are a lot of alternative ways to protect access to personal data. The usual passwords are replaced by multi-layer authentication or just more progressive technologies. These are fingerprints and face recognition functions, keychains, and password vaults. But what is the future of passwords? Will they become an outdated option or stay a necessary part of access.

Why are passwords considered weak?

With the growth of cybercrime, the requirements for passwords are increasing. The first passwords consisted of short, easily-memorized word or numeral combinations, but they were too easy to crack. Now, passwords are sophisticated alpha-numeral combinations, sometimes too long to remember. Nevertheless, it is still possible for hackers to find the solution and get access to your account. Passwords are usually based on some common information like a date of birth, the name of a child, or a home pet, which implies that hackers are able to find out what it is if they have enough time. The other reason why passwords become targets is the fact that they provide unrestricted access to your account. Moreover, many people use the same or similar passwords for many different accounts, so they simplify the process of collecting their sensitive data from multiple sources. Of course, using the same password for every account mitigates the risk of forgetting the password, but reusing the combination is quite risky. Users are sure that they won’t be hacked as the data they store is not valuable enough to be stolen, but it’s a common mistake as almost everyone can be compromised or fall victim to a bot attack that is aimed at spreading spam or malicious links. So, the best way to protect your privacy is not to reuse the same password and exploit multi-layer authentication for your accounts.

The anti-password movement

This movement was established as soon as people understood that usual passwords are more vulnerable than they should be. Passwords are inconvenient and provide multiple avenues for fraudsters to obtain your data and profit from it. The most typical method for hackers to profit from this data is to sell it on the dark web for fast cash. Advanced attacks on logins have been known to shut down entire corporations or launch ransomware campaigns. Credential stuffing is the most well-known form of password hacking, it is based on the reusing of the same password for multiple accounts, pairing it with different email addresses or logins. It is usually aimed at taking over as much information from corporate accounts as possible. Thus, internet users realized that passwords are not the most powerful protection that can be exploited for security goals. So, what was made in addition to, or in place of, the password?

Multi-factor authentication

Single-factor authentication refers to the requirement of only one password to access an account. This method of protection has been used for a long time, but now it’s obsolete. The new practice in authentication is multi-factor access which requires passing two or more layers of authentication before accessing an account. The possible steps of this sophisticated technology could be the PIN code, the server-generated one-time code sent to your email address or mobile phone, or even fingerprints and face recognition.

It makes access more complicated but also serves as an additional barrier to compromise attempts and data thieves. This motivates them to move on to more straightforward targets. While it isn't infallible, it does dissuade attackers from trying anything else, potentially rescuing you from disaster.

Another successful way of protection is the passphrase that is used instead of common password combinations. It is represented as the meaningful or meaningless word combination consisting of up to 100 words. It seems to be hard to remember a long phrase, but it is much easier than remembering alpha-numeric combinations including substitution, capitalization, and different numbers. Hackers will find it incredibly difficult to break into a system since passwords are several words long and can contain an endless number of word combinations. Another good thing about such protection is the lack of necessity to install the special apps or systems required to use this technique. It can be applied to every account without special password character limits.

Is the password dead?

The first hacking attacks were conducted as early as the 80s. Regardless of this, people still use passwords as the main protection force for their private information. So, why can’t we replace it with more modern and convenient technologies?

First of all, it’s related to the ease of creating passwords. The password is generated by the user himself, so there’s no need to create and exploit special services that would be able to provide protection for the account on the user’s behalf. Another point is the privacy of users. The password is one of the more private ways of authentication as it doesn’t require any personal information, it can be a random combination of numbers and lack sense, unlike methods such as biomedical data access, which is connected with personal information that could get out into cyberspace. The last but not the least important point lies in the simplicity of replacing passwords. It can be useful in the event of a major data breach, as it’s easier to change the password than the biomedical options that are used for fingerprints or face recognition.

Conclusion

So what will be the future of passwords? Passwords will definitely be used as one layer of a multi-factor security system for the next few years as there are still no more useful options for saving our privacy than passwords. People are continuing to look for the perfect method of protection, so maybe in a few years, something will finally appear and the world will be able to say goodbye to long sophisticated passwords. Some services have already turned to new systems of access, like one-time codes or fingerprints, but there is still a possibility of being hacked. Indeed, users still believe that a multi-layer system of protection is more convenient than any possible alternative.

Migration to PHP 8

The new version of Passwork now runs on PHP 8. Previous versions of PHP are no longer supported.

New access rights window

The window with access settings for vaults and folders has been completely redesigned. All users and roles having access to a vault or folder are now collected here as well as links and sent passwords.

The rights can now be edited on each tab by selecting multiple objects at once. All modified and deleted objects are marked by an indicator until you save changes. Search filters allow you to display all objects with a certain access right.

Ability to quickly view who accessed vaults and folders

When hovering over an icon next to the name of a vault or folder you can see some brief information about the number of users, roles, links and sent passwords.

Clicking on a list opens up the window for access rights management inside a given vault or folder.

Granting access to individual passwords without adding users to a vault

In previous versions of Passwork, it was possible to send a password copy to users. In the new version, users will see the original password in the Inbox, which will be updated when the original vault changes.

That means you can now give access directly to a password without adding users to a vault or folder.

You can send a password and enable users to edit it, then when a user changes this password, it will be updated for you as well.

Ability to add TOTP keys and then generate 2FA codes

When adding and editing a password, you can add a TOTP field and enter a secret code to generate 2FA codes. The generated code is updated every 30 seconds.

The "Password" field is now optional, so you can keep 2FA codes separate from main passwords.

Adding TOTP keys and generating 2FA codes is available in the web version, browser extension, and mobile app.

Failed login attempts are now displayed in the action history

The action history displays all failed user authorization attempts. This allows you to better track unauthorized access attempts and the actions of blocked users.

You can see all failed login attempts on the Activity Log page by enabling a filter in the Action column.

Ability to enable priority authorization using SSO

The new version of Passwork now allows you to enable SSO priority authorization for all users. You can enable it in the "SSO settings" section.

With this option enabled, only the "Sign in via SSO" button is displayed on the authorization page, the login and password fields appear only when switching to the standard authorization.

Are you sure that your home is protected in the way that you think? Sure, you can secure it with modern locks or an alarm system to protect yourself from robbers who want to steal your money or furniture, but what about those who are looking at your home as a means of stealing your privacy?

As the number of smart electronic devices we use every day increases, we have to make sure that the personal information that is recorded by these devices is safe.

So let’s talk about home security and how to protect yourself from those that are looking for ways to hack your smart devices.

Which smart devices can be hacked?

Almost every smart system used with modern devices is potentially dangerous as hackers know hundreds of ways to obtain remote access to them. But still, some devices seem too ordinary and primitive to be hacked. Perhaps a robot vacuum cleaner or a smart baby monitor. But there are more sophisticated technologies like a smart TV or smart house security system. They're all vulnerable since they're connected to the internet and are frequently part of your home WiFi network. Recent research showed that every one of them has several serious security flaws.

What are the risks?

Many experts note that when it comes to smart home devices, you should be thinking about ‘when’ they will be hacked, not 'if,' because many are notoriously easy to hack and provide no protection whatsoever. Scientists from the European watchdog Eurovomsumers examined 16 regularly used devices from a variety of manufacturers and discovered 54 vulnerabilities that exposed consumers to hacker attacks, with potential implications ranging from security system deactivation to personal data theft.

According to the results of research, hackers can gain access to highly sensitive information such as banking credentials or even utilise many linked devices to stage enormous distributed denial of service (DDOS) operations, which allows them to ruin banking or other service networks.

Whenever most internet users realise the vulnerabilities associated with the usage of computers connected to the Internet, many people still do not pay enough attention to the fact that their home smart devices also present the same danger. As all home devices are commonly connected to the same Wi-Fi network, it gives an opportunity for hackers to get access to all domestic technologies at the same time.

Security gaps

One of the most significant dangers that are presented by smart home devices is the potential for a ‘deauthentication attack’, in which a hacker orders the device to disconnect from the house WiFi. It may cause the blocking of systems and devices, which won’t be able to respond to users’ requests as a result. It was also discovered that some apps designed for home appliances are able to transfer unencrypted data. It means that if hackers break into their system, they’ll gain access to the owner's personal information, such as WiFi passwords or even listen to what happens around the device if it’s equipped with a microphone. A stolen WiFi password may provide hackers access to phones or computers connected to this network and lead to an eventual data leak.

Due to the gaps in security systems, smart devices often have flaws that make them vulnerable to attack. Designers of these devices focus on the comfort of exploitation and multifunctionality of their products, but not on their security. But now, when almost everything from house alarms to refrigerators can be hacked, it becomes a paramount point.

Recent research that took place in America and Europe has shown that about a half of interviewees use smart home devices, but most of them do nothing to protect themselves from being compromised. Thus, even though people know about the risks, they still do nothing to minimise them. One of the possible reasons for such behaviour is the lack of knowledge and accessible information about how to make the usage of smart home devices secure.

How can you secure your home devices?

Of course, the most basic way to protect yourself from the hacking of your smart home devices is just not to use them and replace them with less functional but safer options. But what if you can’t go without such a pleasure? Well, Euroconsumers — one of the most well-known private organisations for consumers — developed a list of recommendations that can help people who want to maintain their privacy while using smart devices:

1. Use an ethernet cable instead of Wi-Fi to connect your devices to the network where possible;

2. Create strong multilayered passwords for your devices and Wi-Fi;

3. After installing your WiFi network, always change the default name;

4. Always keep your devices up-to-date and switch them off if you’re not using them at a certain moment;

5. When you use a device for the first time, always finish the setup procedure;

6. Do not buy cheap devices with a low level of protection.

Conclusion

When we’re talking about smart devices, we’re not just talking about full smart house systems such as alarms. Rather, we’re talking about smart appliances such as TVs, doorbell systems, vacuum cleaners, and other common household things. Using them makes our lives more comfortable and saves time and energy. However, they each have their own flaws, and many are vulnerable when it comes to hacking. So, consumers should pay attention to this point of using smart devices and consider all possible ways to protect their privacy without refusing to exploit such useful appliances. If you use one of these devices, try to get more information regarding what manufacturers pay more attention to regarding the security of their goods. Moreover, make sure to protect your own devices from hacking. It won’t take a lot of time or effort, but it will save your sensitive data and protect you from being compromised.

If you still haven’t heard about Starlink, you’ve definitely heard about its creator — Elon Musk.

Elon Musk is a billionaire entrepreneur most famous for his electric vehicle firm, Tesla, and his space exploration company, Space X. Maybe you learned about him from our news headlines talking about his attempts to acquire Twitter or his past endeavors stirring up trouble on social media. Perhaps you only know him as one of the world's wealthiest people. Starlink is the less known facet of Elon Musk’s career that is focused on providing internet to every part of the world including hard-to-reach places, and that’s what we’re going to be talking about today.

What is Starlink, exactly?

Starlink is the name of the global and constantly growing network of orbital satellites overhead, based on SpaceX technologies. This project began in 2015, and the first prototype satellites were sent into orbit in 2018. In January 2021, after three years of development and successful launches, Starlink reached 1,000 satellites. Over the course of the next year, this number doubled. Now, Starlink has more than 2,000 operational satellites orbiting the Earth. Indeed, it’s still just the beginning. The plan will be completed as soon as the network covers most parts of the Earth’s surface. To do this, Starlink requires about 12,000 satellites in orbit.

Currently, the project’s creators are assuring the provision of its service in 32 countries. This number will increase every year. However, the budding broadband provider still has a backlog of prospective customers waiting to receive equipment and connect to the system.

How fast is Starlink?

Starlink offers high-speed broadband internet, the spread of which, according to the speed-tracking website Ookla, is above 100mbps in more than 15 different regions. When we’re talking about the United States, Starlink offers average download speeds of around 105Mbps and upload speeds of around 120Mbps, which is about five or six times faster than their satellite rivals. Elon Musk is focused on doubling the average internet speed and reaching 300 Mbps. In any case, even now, we can observe his success as the Starlink Internet system really is one of the fastest in the world.

How much does it cost?

The initial cost of the service was $99 per month, and the initial one-time payment for the satellite dish and router was $499. As Starlink is focused on the availability of the internet, it was announced that the cost of the service is going to decline in a few years. But, in March of 2022, the company announced a price increase. So now, the monthly payment is $110 and the initial payment for the equipment is $599. This price is quite high for satellite Internet, but the creators of Starlink bet on the wide coverage of their network and its availability in hard-to-get places.

As the president of SpaceX said last year, Starlink aimed to keep pricing as straightforward and transparent as possible, and that there were no plans to add more levels to the service. However, in 2022, a new premium level with a scanning array twice as large as the normal plan and download speeds ranging from 150 to 500Mbps appears to be modifying that strategy. This option costs $500 per month, and the initial payment for equipment will be $2,500. Now the company is taking orders for that tier, with the service set to arrive later in 2022.

The pros and cons of Starlink Internet

Starlink, like any other modern technology, has some benefits and drawbacks. Let's take a quick look at them.

The pros of Starlink:

1. Faster Internet. The internet offered by SpaceX is definitely faster than traditional satellite Internet. Starlink is so quick that it's almost impossible to compare it to traditional satellite connections.

2. Relatively cheap. Starlink's internet service is reasonably priced. In rural and suburban locations, it is less expensive than cable and satellite internet. Suburban consumers pay the same price as city residents in many areas, but they get much slower internet.

3. Wide availability. Regardless of your location, Starlink is available to every customer. It has wide network coverage and provides fast, unlimited Internet from Antarctica to the middle of the ocean.

4. Faster disaster recovery. Storms, tornadoes, wildfires, and floods can all cause internet cable to be seriously damaged. After any type of disaster, the recovery of the cable Internet takes quite a lot of time. The process of fixing it isn’t just costly but also time-consuming, unlike Starlink. The Internet will be available straight away after the disaster.

The cons of Starlink:

1. Hardware installation. For many users, hardware installation could become a problem as the creators of Starlink don’t provide the installation of the equipment needed for using their network. Thus, customers have to install the equipment themselves or hire professionals to spend extra money.

2. It’s not portable. When compared to cellular internet, Starlink is not as portable. We can use our phones to access the internet from any place. The Starlink dish is not at all portable. Though the dish can be installed above an RV or a boat, unfortunately, it is not small enough to be carried easily.

3. Service disruptions depend on the weather. It's common for satellite service to be disrupted by rain, storms, or solar flares. However, this isn't a major pro for cable internet either; it’s also subject to this type of disruption.

As the number of Starlink’s users increases, the question of the security of this Internet connection has become acute. People want to make sure that the provider that they use is safe enough and that nothing threatens their personal data.

So, is Starlink secure?

The main problem of satellite Internet is that some of the information carried by satellites can be intercepted as it is translated to and from the Earth. Some of that data can also be changed before it reaches its intended destination. This does not, however, necessitate the use of specialized equipment. According to a recent study, this could be accomplished with $300 worth of equipment. It's vital to keep in mind that this issue does not affect all traffic. If you're using an encrypted connection, this form of assault is likely to be unsuccessful. However, it does underline the reality that as satellite internet becomes more ubiquitous, cybercriminals will have additional chances.

Conclusion

Starlink is a quickly growing and highly available technology that is just at the start of its development. However, it already could demonstrate great advantages over the cable network. Like any modern technology, it has several disadvantages, such as weather dependence and the risks related to satellite networks. Now, SpaceX promises a very high level of service with wide coverage, but as practice shows, not all of their promises are worth trusting. If you’re going to get the Starlink dish, you have to consider this issue deeper to make sure that you’re making the right choice.

From smartphones to automobiles, almost every device is equipped with Bluetooth technology nowadays. Many people use it every day while connecting to headphones, sending files, or making remote calls in their cars. However, most people are unaware that using Bluetooth carries a number of risks when it comes to your privacy and safety.

What is Bluetooth?

Bluetooth technology is a standard for creating a local network that allows neighboring devices to exchange data wirelessly. In other words, you can use Bluetooth to transfer data between devices such as your phone and headphones without the use of a cable. Bluetooth is widespread and free to use, that’s why it is so popular with device creators and consumers.

Bluetooth was invented in 1994 by Ericsson — the telecommunications equipment manufacturer. Now, you can find this technology in almost every electrical device around the world. Even smart household appliances are equipped with Bluetooth nowadays, so you can send instructions to your refrigerator or vacuum cleaner remotely.

Bluetooth hacking

Of course, as with most standards, Bluetooth has its disadvantages and security vulnerabilities. Bluetooth allows devices to communicate with one another across short distances and for a limited time. As a result, most Bluetooth hackers focus on getting close to a target and carrying out the assault in a short amount of time. Particularly in areas where people tend to linger around. There are a number of places that pose a great amount of danger to your devices. For example, cafes, the underground during rush hour and on the bus.

However, when the attacker’s target moves out of range, it could stop the attack and ruin the hacker’s plans. It's worth noting that some attacks can be launched from hundreds of meters away. So moving a few steps isn't the same as being out of range.

Some hackers are also able to control your device for under 10 seconds using Bluetooth. Even more concerning is the fact that hackers can accomplish this without engaging with the user.

There are a variety of Bluetooth hacking techniques:

1. Bluejacking

This type of cyberattack on Bluetooth connection lies in sending spam messages via Bluetooth. One Bluetooth-enabled device hijacks another and sends spam messages to the hijacked device. First of all, this can be annoying to get such spam. But if you click it and accept files from an unknown device, you may get into big trouble. The message may contain a link that will lead to a website that is designed to steal your personal information and compromise you.

2. Bluesnarfing

This type of attack is similar to the previous one but much more detrimental to your privacy. During these hijacking attempts, hackers can not only send spam messages to one’s phone, but also collect some private information like chat messages, photos, documents, or even credentials from the victim’s device. All of this will be used to compromise you or for extortion attempts.

3. Bluebugging

This is the last and the most dangerous type of Bluetooth hijacking. Hackers use your device to establish a secret Bluetooth connection. This connection is then used to acquire backdoor access to your device. Once inside, they can monitor your activities, gain your personal information, and even use your personality on your device's apps, including those used for online banking. This type of assault is known as blue bugging since it resembles bugging a phone. Once hackers get access and complete control over the phone, they get the opportunity to make phone calls themselves and listen in on every phone conversation.

Bluetooth security concerns

If you think that the direct invention of hackers is the only danger that Bluetooth presents, we have some bad news for you. Many apps including popular ones such as Google or Facebook can monitor the location of users through the use of Bluetooth technology.

By switching on Bluetooth, you enable the transmission of information, but you also enable your device to catch adjacent Bluetooth signals. Thus, Bluetooth signals are used by app developers to pinpoint your location. So, the IT companies that develop apps can find out the information about your location wherever you go and keep track of your everyday activities. The most terrifying aspect here is that Bluetooth enables extremely precise tracking. The good thing is that most app creators write that “the usage of their apps requires Bluetooth utilization” in their privacy statement. Unfortunately, the majority of consumers do not read the privacy statements of the apps they use, so they automatically accept all the requirements and rules of the new app.

To protect yourself from activity and location tracking, you should read each app’s privacy policies and not use apps that require Bluetooth. If you determine that some of the apps you regularly use are requiring Bluetooth, you can disable the location tracking function for them.

What do we need to do to safeguard our Bluetooth connections?

In mentioning all of the risks associated with the use of Bluetooth, we have to give you some advice regarding the safeguarding of your devices.

1. Make your Bluetooth device non-discoverable. This can be done in your device’s settings.

2. Do not send any sensitive information via Bluetooth as it can be caught by intruders.

3. Do not accept any files or messages from unknown devices via Bluetooth, especially in crowded places.

4. Always turn your Bluetooth off after using it to prevent unwanted connections and breaches.

5. Don’t share anything via Bluetooth in crowded places, even if you want to connect to your friend’s device.

6. Install some security patches to protect your device and stop any possible tracking via Bluetooth.

Conclusion

Bluetooth is a common and useful technology that is used in almost every device due to its convenience and fast connection. But the simplicity of its technology leads to several flaws, which is why Bluetooth can’t be named a very secure standard. Nevertheless, most people cannot avoid using this technology — it’s just too widespread. To keep your device safe, we recommend following the aforementioned security rules.

What is WebSocket?

The WebSocket API is a cutting-edge technology that allows the opening of bidirectional interactive communication sessions between a user's browser and server. You can use this API to send messages to a server and obtain event-driven responses instead of polling the service. WebSocket is a stateful protocol which means that the connection between the client and server will remain open until any of the parties terminate it.

Consider the client-server communication: when the client initiates the connection with a server, a handshake occurs, and any other request will go via the same connection until either of the parties closes the connection.

WebSocket is a good thing for services that require constant data transmission, like network games, online trading sites, and other websites that work continuously.

Where is WebSocket used?

1. Real-time web applications. Such services use the WebSocket to provide constant data translation to the client. This type of connection is preferred over HTTP as continuous data transmission goes through a connection which is already open. This makes the process much faster. A good example of a real-time web application is a Bitcoin trading webpage that continually pushes constantly changing data about the bitcoin’s price to the client;

2. Gaming applications. In such applications, data must be constantly transmitted from the server to the client’s computer. Otherwise, the collective acts between multiple users of the application will be unavailable;

3. Chat applications. WebSockets are used by chat applications to create a connection just once for the purpose of exchanging messages, video and audio between the interlocutors.

The Vulnerabilities of WebSocket

WebSocket technology causes a lot of excitement and at the same time disagreements among web developers. Despite all the benefits that it provides, it still has some risks as the technology is relatively new. Due to the complexity of WebSocket programming, it’s hard to provide comprehensive security for applications that use this technology. The constant transfer of data without closing the connection after every request opens up an opportunity for hackers looking to acquire access to the client’s data.

In early versions of WebSocket, there was a vulnerability named ‘cache poisoning’. It allowed the attack of caching proxy servers, particularly cooperative ones. The attack occurs in the following manner:

1. The attacker invites the client to attend a special webpage;

2. This webpage starts the WebSocket with the hacker’s website;

3. The page makes a WebSocket request that can’t be accepted by a number of proxy servers. The request passes through that server, and after that, the servers believe that the next request is the new HTTP one. But in fact, it’s a WebSocket connection that continues translating data. Both ends of the connection are now controlled by the hacker, so the hacker can transfer malicious data through the open connection. The deceived proxy-server will get and cache the malicious data;

4. Indeed, every user who utilises the same proxy-server will get the hacker’s code instead of real jQuery code.

The risk of such an attack had remained theoretical for a long time, until an analysis of WebSocket’s vulnerability showed that it really can happen.

Due to the existence of that vulnerability, WebSocket’s developers introduced ‘data masking’ to protect both parties of the connection from attacks. Masking prohibits security tools from doing tasks such as detecting a pattern in traffic.

WebSockets aren't even recognized by software such as DLP (Data Loss Prevention). They are unable to analyse data on WebSocket traffic as a result of this. This also makes it impossible for these software tools to detect problems such as malicious JavaScript and data leaks. It also makes the WebSocket connection more vulnerable than HTTPS.

Another disadvantage of WebSocket protocols is that they don’t manage authentication. This must be handled individually by any application-level protocols. Especially when sensitive information is being transferred.

The next type of cyber attack that WebSocket can be exposed to is tunnelling. Anyone can use WebSockets to tunnel any TCP service. Tunnelling a database connection right through to the browser is an example of this. A Cross-Site Scripting attack evolves into a comprehensive security breach when a Cross-Site Scripting assault is carried out.

Also, it’s necessary to know that data transfer over the WebSocket protocol is done in plain text, similar to HTTP. As a result, man-in-the-middle attacks on this data are the real threat. Thus, it’s better to use the WebSocket Secure (WSS:/) protocol to avoid data leaks.

How can we improve WebSocket security?

After looking through the main vulnerabilities of WebSocket, it’s necessary to take a look at the ways and tools that are able to protect your WebSocket connection.

First of all, good advice would be to use the wss:// protocol, instead of ws://. It’s really much safer and able to prevent a huge number of attacks from the outset.

Also, it’s necessary to validate the data that comes from the server via a WebSocket connection. Data returned by the server can potentially be problematic. Messages received from clients should always be treated as data. It's not a good idea to assign these messages to the DOM or evaluate them as code.

Another way to protect your connection is via a ticket-based authentication system. The separation of the WebSocket servers that handle headings of transmitting data from the HTTP servers hinders the authorization of headings that are based on HTTP standards. So, ticket-based authentication is a solution to this problem.

So, how secure is WebSocket?

To sum up, we can say that WebSocket doesn’t have a perfect security system, as is the case with any new kind of technology. It’s all due to the complexity of its creation and maintenance. WebSocket has enough vulnerabilities, such as a lack of authentication measures or its data input attack susceptibility, to enable attackers to transmit malicious codes. So, one should always be wary of this fact.

However, WebSocket is a progressive technology that is great to use in some spheres like gaming or trading. That’s why it should be improved to make its usage secure for every connected client or server.

Upon entering your account on a website or in an app, you might be asked to enter a word or a number combination from a strange-looking picture. They are usually distorted and sometimes it can take a few seconds to determine the symbols on the picture. This security step is named CAPTCHA and seems to be useless and tedious, especially if you have some problems with recognizing and entering the right combination. But to be honest, this simple test plays an important part in the security system as it makes access to websites or online purchases wholly unreachable for bots and computers.

What is CAPTCHA

CAPTCHA is an abbreviation that can be decoded as a Completely Automated Public Turing Test to Tell Computers and Humans Apart. It’s a type of test that helps the websites’ creators minimise the ability of a bot's registration or purchasing power. They're also referred to as "Human Interaction Proof" (HIP). CAPTCHA is widely used across the internet and mobile apps alike. The most common type of CAPTCHA is the picture that contains distorted letter combinations that you should comprehend and write down in the answer box. If you wrote the right symbols, the system gives you access to the site or to the following task. You can also see a variety of CAPTCHAS on different websites. Some of them require you to take a look at a number of pictures and choose those that contain a target object such as bicycles or traffic lights.

How does CAPTCHA work?

CAPTCHA came about mainly because of certain individuals’ attempts to trick the system by exploiting flaws in the computers that power the site. While these individuals are likely a small percentage of total Internet users, their activities have the potential to harm a huge amount of websites and their users. A free email provider, for example, might be inundated with account requests from automated software. That automated application could be part of a wider scheme to spam millions of people with junk mail. The CAPTCHA test is used to determine which users are genuine people and which are computer programs.

The internet and its computers are built using a proprietary coding language. Because of the unique and complex norms that human languages adopt, as well as the slang that humans use, computers have to spend a lot of time understanding them.

Most CAPTCHAs include visual tests, which the “brain” of the computer can’t figure out; it’s much less sophisticated and it's definitely harder for them to determine the pattern in pictures. While humans will spend a few seconds on CAPTCHA, artificial intelligence has to spend much more time on finding a consistent pattern.

There’s also an alternative to a visual CAPTCHA — one that is based on audio access. That type was developed to make it possible for CAPTCHA to be passed by those who have a visual impairment. Although there are more deaf than blind, approximately 75% of all adults require some kind of visual correction, so it’s much more likely that you’ll encounter someone who can’t focus on the letters on screen. After all, they are usually quite hard to read. Usually, audio CAPTCHA is a succession of spoken characters and numerals. Frequently it also is accompanied by background noises and sound distortion to protect against bots.

The third type of CAPTCHA is a contextual one. The task for the user is to interpret some text with his or her own words, keeping the main idea of the passage. While computer algorithms can recognize significant terms in literature, they aren't very adept at deciphering the meaning of those words.

It’s also important to distribute the CAPTCHA pictures in a random order to every user. If imaging would repeat constantly or would be displayed in a specific order, it would be easy for spammers to trace the subsequence of the pictures and program a computer system that would be able to pass the test automatically based on the CAPTCHA’s order.

Turing test

CAPTCHA was based on the Turing Test. Alan Turing, an ingenious mathematician, who was named “the Father of modern computing”, suggested this test to find out whether the computer is able to think like a human or not. The point of the test is that there are a number of questions that must be answered by two participants. One of them is a real person while the other is a computer. There’s also an interrogator whose task is to find out which answers were given by the machine and which ones were given by the human. If the interrogator isn’t able to understand who is who, the test has been passed.

The main goal of CAPTCHA’s creators was to create a test that could be easily passed by a human, but not by a machine.

The pictures that we see on the screen that we need to pass the captcha test are usually very complicated as it must be possible for every user to enter it. But bots are mostly unable to determine the text that is presented in the form of a picture.

Who uses CAPTCHA?

CAPTCHA is a type of verification tool that is widely used by websites and apps to ensure that a user is not a robot.

It is usually used to protect online pools from bots’ votes employed by scammers to cheat. Another purpose of using CAPTCHA is to restrict access to websites where consumers can create free accounts, such as Gmail. Spammers can't use bots to establish a slew of spam email accounts because of CAPTCHAs.

CAPTCHA is also used by ticket services to prevent profiteers from buying too many tickets for big events. This helps honest people to buy tickets in a fair manner while preventing scalpers from putting in hundreds of orders.

Finally, CAPTCHA is used to prevent spamming messages or comments on websites where it’s possible to contact the page’s user directly. It helps to stop bots from automatically sending spam and spoiling the ratings of products or services.

To sum up, CAPTCHA is a good tool to prevent the creation of spamming bots or automatically controlled web pages that spread viruses. It helps the creators of apps and websites to verify that a user is a real person, and not a computer programmed to spoil the system. This small but necessary stage of identification of the user is really helpful and recommended for exploitation on any websites where users are able to create free accounts. If you want to use CAPTCHA to protect your own website, you should be aware of the numerous failure possibilities that you may encounter. We recommend using a service like Google's reCAPTCHA to generate one for you. It’s also a good idea to download an antivirus program and use it together with CAPTCHA to keep your device secure.

When we look at the statistics, the number of cybercrimes increases year on year. Hackers have invented a wide range of tools that can crack your password or get your access information with ease. But there are also other ways of violating your privacy. Every click you make is tracked by websites, advertising agencies, ISPs, and other third parties. Thus, you need to secure your privacy online using a web browser optimised for making your web-surfing secure. So, which browsers are really designed to preserve your personal data and prevent leaks?

Everyone knows that Microsoft Edge or Safari are built into smartphones and laptops supported by the corresponding operating systems. So most users are unconcerned about the browser they use assuming that the default option is the best one. Although browsers like Safari, Google Chrome, or Opera are the most common, they really can’t pretend to be the most secure and privacy-conscious. Indeed, there are some less common but highly powerful and privacy-focused browsers that could provide you with plenty of embedded privacy settings that can block cookies, ads, and data tracking. It’s pretty difficult to name the best one as each of them contains its own privacy features enabling them to become contenders for victory. So let’s go through these browsers and their privacy customizations to help you make the call.

1. Tor Browser

Tor is one of the well-known privacy-oriented browsers. It is based on Firefox’s browser and equipped with its own hidden relay servers that are focused on anti-surveillance functions. It automatically erases your cookies and browsing history on the fly. Tor makes users’ internet access anonymous by encrypting their traffic in at least three separated layers (nodes) that are decentralised and run by volunteer computers. Each node focuses on a single layer of encryption, making it impossible to get the entire message in any of them. Thus, no one can trace your online activity or identify you until you deliberately identify yourself. The unique technology of Tor is also available to lessen the uniqueness of your fingerprint, which is an unmatched feature in successfully decreasing the possibility of identifying a user.

Of course, Tor Browser has its drawbacks. Due to the complexity of protecting certain processes, the speed of your internet could be affected. Also, the NoScript function may break some websites. Moreover, there is a possibility that law enforcement is able to see who is using the Tor browser, even if they are not aware of what people do there.

2. Brave

Brave was founded in 2016 and despite it being a quite new browser, it is worth considering. This privacy-focused browser is based on a Chromium network and truly packs a punch with features like an ad-blocker, anti-tracking, and anti-fingerprinting technology. Brave also automatically changes your connection to HTTPS, as it's always important to have a safely encrypted connection. The security options of this next-generation browser enable you to choose which data to erase when you exit the program. Another useful thing is the embedded feature that could prevent scripts from launching. Recently, Brave entirely switched to a Chromium core, which simplified the process of bringing over their Chrome extensions. It allows the browser to be made more functional and convenient. Nevertheless, users still should be cautious in selecting extensions, as it’s important to use ones that respond to individual security requirements.

Despite the fact that Brave is open-sourced, some users may be wary of its Chromium foundation. Brave’s advertising model is particularly contentious, as it favours adverts that benefit the browser over those that benefit the websites you visit.

3. Mozilla Firefox

Firefox is well-known for the variety of settings and extensions that it provides for its users. It’s one of the more commonly used alternatives to Chrome or Safari. Although Firefox doesn’t release updates as frequently as the previously mentioned browsers, it does so on a regular basis. If we take into account the fact that Mozilla is a non-commercial organisation, it’s worth evaluating the work of the company’s volunteers, who do a great job to ensure that Firefox has the most up-to-date security systems in place. Firefox’s security features really have something for everyone. It includes phishing and malware protection, for example, banning attacked websites, and informing the user about attempts of installing site add-ons. It’s also equipped with ad blockers and tracker-detection systems. Moreover, it’s easy to use due to its minimalistic style and simplicity. However, be sure to turn off the telemetry feature as it shares your browser’s data with Mozilla. Such features might disturb the users that appreciate their privacy, but that can be easily disabled via the settings tab.

4. Epic

The main point in using Epic is that you’re able to benefit without changing the built-in extensions. It’s already configured to make the process of internet access secure and confident. Its customizations will block cookies after every session, preventing data tracking and unwanted ads. Epic also has an option to search the information via DuckDuckGo (A privacy-focused search engine that is a good tool to ensure your personal data stays safe). This browser is fundamentally aimed at making your internet access private. It disables auto-syncing, spell-check, auto-fill, and many other functions that can collect users’ personal information. Of course, it doesn’t save you browser history, access credentials, and cookies. Epic also aims to hide your IP address in any possible way in order to protect the information about your location and your device’s data.

While the settings focused on high privacy can disable some sites and functions, which means the browser is not ideal in all cases, extensions can be changed at the expense of privacy.

The explicit disadvantage of the Epic browser is that it’s based on the Chromium code, which is not open-sourced. So there’s no certainty that this code will be independent in the future.

Conclusion

So, what browser can be named the best one suited to protecting your identity and personal data? Well, none of them can be completely private. There are a number of browsers that claim to be the most private and protected ones, but even they have flaws that can disturb some users. So, you should choose the browser that mostly satisfies your own requirements and seems to be the best one for you. In this article, we’ve collected some facts on the ‘chef’s pick’ of browsers. Now, the decision is in your hands.

What is a brute force attack?

Among a myriad of different cyberattacks, the brute force attack seems to be the most common and primitive way of hacking. This technique involves guessing login information through trial-and-error, where hackers try all conceivable combinations in the hope of guessing correctly.

The term “brute force" refers to the method itself, being both brutal and forceful. Despite the fact that brute force attacks are a pretty ancient cyberattack approach, they still remain a prominent technique among modern-day hackers.

Types of brute force attacks

A brute force attack can be split into a few different types, each kind employing a variety of techniques that serve to unearth your private data. You should be aware of how cybercriminals apply each type in order to ensure maximum protection.

1. The simple brute force attack — this refers to the process of simply guessing the login credentials via logical deliberation, without the use of any software. Hackers just go through every standard combination of letters and numerals, perhaps combining this with some information that they know about you. This method is cumbersome yet reliable as many people still use primitive and common passwords and PINs like “user1” or “12345” in order to remember it easily. Also, users, who use the same password for every account put themselves in extra danger; if the hacker does guess one password correctly, then it’s likely that they’ll be using that password as the first port of call when it comes to other accounts.

2. A dictionary attack — this is a type of brute force attack that involves the user submitting a very large variety of different password combinations. Although this kind of assault is technically a brute force attack, it takes a significant place in the process of cracking passwords. The name of this technique comes from the actions that a hacker performs during the break-in attempt. The criminals scan through password dictionaries modifying words using different numbers and abbreviations. It usually takes a lot of time and has poor success rates when compared to newer techniques. However, it’s easy to do if you have a computer at your disposal.

3. A hybrid brute force attack — this type combines the two that we’ve just looked at: the brute force attack and the dictionary attack. Combination passwords, which mix common words with random characters, are cracked using these approaches. Usually, it starts with a certain username which is used as a base for the following actions: hackers input a list of words that potentially could be included in the password, then combine them with different characters and numbers until they reach the correct password.

4. Reverse brute force attack — contrasting with other types of brute force attack, the reverse attack starts with a known password. Usually, hackers get these from leaked databases that are freely available on the internet. Attackers choose one password and look through millions of accounts until one matches. Of course, it’s easier for the criminal to locate a match when the password includes a name or a birth date, so it’s better to avoid using such information in your password.

5. Credential staffing — this type of attack is based on users’ cybersecurity illiteracy. Hackers collect and store lists of already cracked or stolen passwords and usernames connected to them and then go through dozens of other websites to see if they can obtain access to other accounts of the same user. Thus if the person utilises the same password for various social networks, apps and websites, he or she allows the attacker to get every bit of private information contained on each account.

6. Botnets — this type of attack can be combined with any of the above. The main point of a botnet attack is to use extra computational resources to attack the victim. This way, hackers manage to avoid the costs and difficulties associated with running programs on their own systems by exploiting hijacked machines to carry out the brute force attack. Furthermore, the usage of botnets provides an additional layer of anonymity which is also desirable for hackers.

Brute force attack tools

It can take a long time to crack the password of somebody’s email or website, so hackers have created some software to assist them in breaching accounts, which makes the process easier and faster.

1. Aircack-ng is a toolset that provides the hacker with the opportunity to enter various Wi-Fi security systems. They’ll be able to monitor and export data through the use of this software. They can even hack companies using techniques such as spoofing access points and packet injection. Such software is free and can be acquired by anyone.

2. DaveGrohl is a brute-forcing tool that was made to assist in dictionary attacks. It offers a mode that helps hackers to attack a victim using the force of several computers.

3. John the Ripper is a program made for recovering passwords. It supports thousands of encryption systems including those used in macOS, Unix, Windows, various web applications, network traffic, and document files.

These programs can quickly go through all conceivable combinations and choose the correct one to breach a variety of computer protocols, encrypted information storage systems and modems.

Examples of brute force attacks:

Brute force attacks are so common that almost every person or organisation has at least once fallen victim. Even worldwide organisations that are known for their robust security systems could be exposed to a brute force attack. For example, in 2018, it was uncovered that Firefox’s master password was quite easy to figure out. Because of this, nobody knows how much personal data was actually leaked into the network. This wasn’t the only brute force attack to occur that year. Unknown hackers compromised the accounts of numerous members of the Parliament of Northern Ireland.

Three years before that, Dunkin Donuts, a doughnut and coffee franchise, became a victim of another brute force attack that resulted in people losing large quantities of money due to a breach that took place in the company’s mobile app. Cybercriminals utilised brute force to obtain illegal access to the credentials of more than 19 thousand people, eventually taking their money. Unfortunately, the company didn’t make users aware of the attack and people couldn’t take the appropriate precautions to protect their personal data and money in the future, so a complaint was eventually filed against it.

Despite most people actually being aware of the measures required for privacy maintenance, a lot of users still disregard the rules of cybersecurity by trying to simplify access to their accounts with a simple, reusable and easily memorable combination. This way, they make themselves potential victims of brute force attacks, which are largely possible thanks to the carelessness of cyber-civilians.

Hacking attacks are often pretty minor and can include things such as personal data theft for the purpose of extortion. These attacks usually fail, but can sometimes be really devastating when the subject is a business or government organisation; we’re talking huge monetary losses. There are a huge variety of applications and software that were created to protect users from theft of data that is kept on their electronic devices or online accounts, and one of them is a firewall.

What is it?

A firewall is a network security system that filters incoming and outgoing network traffic according to the firewall's rules settled by a user. The main goal of the firewall is to minimise or just to remove undesired network contacts and let in all admissible communication. Firewalls are a significant part of cybersecurity and can be used in parallel with other tools to provide a high level of personal data security.

Firewalls are useful for every Internet user, no matter if we’re talking about a company or an individual user. Hackers can attempt to exploit every computer connected to the network in their malicious purchases. Your computer might be hacked in order to spread damaging links through your email or social networks accounts. That’s why you should be aware of how to protect yourself from breaches.

A firewall can be built into an operating system; an ordinary user usually doesn’t notice the work of this protective system until it reveals a threat in an incoming file.  

What is inside it?

A firewall could be a type of software or hardware that looks for threatening elements that have been flagged as dangerous. Hardware options for intercepting traffic travelling between the broadband router and user devices are frequently included in routers. Software options are programs that track the data that enters and exits your computer. Regardless of the type, the main function of the firewall is to block the access or dispatching of data packets that have been identified as a safety risk. This reversible security system not only protects your computer from attacks but also prevents the spread of malicious data through the network. It can also be used to block unwanted applications.

For example, if an employer wants to control the work of its employees, they’re able to set the system to block certain apps such as Skype, gaming apps, or social networks. Also, firewalls provide an opportunity to block unwanted advertising while controlling access to traffic. A good example of this function can be found when connecting to certain kinds of public WiFi, specifically when you should enter your phone number or email address to get access.

Now let's take a look at the three most common types of firewalls: packet filtering, proxy service, stateful inspection and NGFW. Of course, they are quite different in how they monitor and filter network communication.

Packet filtering

Packet filtering, also known as a ‘stateless’ firewall, analyses particular packets (little data units) one at a time using a set of filters. Thus, the system finds out and stops packets that contain danger while allowing the rest to proceed to their destination. This type of firewall is based on the filtration of unique headers of the packets — the main part that contains basic data like the origin of the packet and its destination.

Proxy service

An application firewall (or proxy service) is quite an efficient tool. It acts as a cyber agent rather than a filtering system. They safeguard your network location from any malicious actors by effectively producing a ‘mirror’ of the computer behind the firewall that excludes the possibility of direct communication between your computer and the information itself. But this type has some flaws. Primarily, it works slower than firewalls of other types and generally has application limitations.

Stateful inspection

Stateful firewalls are more versatile than the previous types as they are able to evaluate not only the headers of the packets but also the variety of aspects that each data lot contains. To pass the firewall, the incoming packet must correspond to the trusted information defined by the firewall rules. This type of firewall is the most streamlined and provides efficient security.

NGFW

The last genus of firewalls is also attributed to application firewalls, although developers usually call them next-generation firewalls (NGFW). This type includes the best of the previous generations of firewalls and also includes a more comprehensive double-checking of packets. It prevents system mistakes in detecting potentially threatening traffic. The newest firewalls are also equipped with extra security systems like VPNs, IPSs (intrusion prevention systems), and identification control systems. This allows users to utilise just one app or kind of software for multi-layer security.

By using firewalls, you mitigate the risks of data theft and the unauthorised entry into your personal devices and accounts. These systems provide safety by establishing protective filters inside every part of your network to detect and eliminate threats like backdoors, viruses, remote logins, or spam.

Also, firewalls vary depending on their appointment. Some of them were created for personal or small-group (under 100 people) use. A good example is a firewall that is built into the Windows operating system. Others have been developed for companies with 1,000 or more employees. These ones should be attentively set up and are usually controlled by an in-house company programmer.

Now, let's talk a bit more about system-based firewalls. As previously stated, traffic that passes through a firewall is compared with the firewall's rules to figure out whether it can be accepted into the system or not. The program contains a list of rules which is consistently compared with incoming data packets. Every rule begins with an index word: accept, drop or reject. The system acts according to those words and the following directions. If the packet satisfies the direction indexed with ‘accept’, it’ll be accepted. Indeed, if it satisfies the ‘reject’ direction, that traffic will be blocked with an ‘unreachable’ error tag. Also, the ‘drop’ means that the traffic will be blocked without sending a reply.

That is, of course, just a ‘tap on the water’ explanation of what a firewall is. For a deep dive, visit https://www.bu.edu/tech/about/security-resources/host-based/intro/.

Almost every user of the internet faces hacking at least once. Cybercriminals have invented a wide range of techniques that aim to crack your password or harvest the credentials and personal data including financial and banking details that are stored on your computer. The timely detection of break-ins may save your privacy and protect your data from being compromised. That’s why you should always be aware of the signs of being hacked and the actions to be taken if you do find yourself in such a situation.

To begin with, it’s important to confirm whether you’ve been hacked or not. Nowadays, the Internet provides multiple ways to do it:

1. Information about almost every cyberattack is available on the Internet. Various news sources publish alerts about data breaches that could be an early indicator that your account has been compromised and that you should take action. Indeed, it’s important to make sure that you have at least one reliable source which provides information about cyberattacks.

2. There is a range of websites available that provide information about every hacked account. One of them is “Have I Been Pwned” which contains a wide database of records about cyberattacks and compromised accounts. To check the security of your account, you should just enter your email address and the system will tell you if your data was the subject of a hacker attack. A positive result doesn’t guarantee that your privacy was violated by cybercriminals, but it does mean that some of your login credentials may have become publicly available.

3. Another powerful tool for ensuring the security of your data is Dehashed.

It's a more comprehensive program than the previous one. Just enter any keyword connected to your account like an old username and Dehashed will surf the Internet to check whether that nugget of your private information has been leaked to the public.

4. Most official public apps and sites alert users about access attempts by sending emails or text messages. So, if you get suspicious alerts that someone has accessed your account from a peculiar IP address or at a strange time, check your VPN to make sure it wasn’t you, and if it wasn’t, there’s a high likelihood that you’ve been hacked.

5. To mitigate the risks of being hacked, check the security of sites that you use regularly. There are a lot of tools that can help you to do that. One of the best is the Sucuri Site Checker. To find out if one of your daily used sites was attacked or endangered your private data, you should enter the website link and the program will provide you with information about any threat that the site could pose. If you reveal that the website you use every day is risky, it would be better to change the password of any account connected to that site and also check the safety of your accounts with the tools aforementioned.

It’s also worth checking for suspicious activity on your account manually. Many sites and apps provide the possibility of tracing recent activity and it’s a wonderful way to find out if anyone else has been using your account. This feature gives information about where, when, and from what device you logged in. Frequenting this setting is the thin end of the wedge of successfully protecting your data; it ultimately prevents any undetected interference. If you have some active sessions opened in an unknown place or from an unknown device, you’ll be in the know. Such an issue can simply be solved by changing the password and logging out all existing sessions. Besides, it's better to protect your account by activating two-factor authentication in addition to changing the main password.

What should you do next?

First of all, you should notify your friends, colleagues, and other people you contact through the hacked account to make sure that they don’t fall prey to the activities of your hacker. Most shallow cybercriminals use your account to prolong the hacking chain. They pretend to be you and send messages or emails asking about material help for an ill grandma or for a phone number to send an SMS with a malicious link, pretending that it is needed to recover access to a locked account of theirs. Nowadays, almost everyone knows about such criminal ploys, but elderly people or loved ones often still fall victim. Thus, it’s necessary to alert everybody that someone else is using your account for the purposes of scamming.

The next significant recommendation is not to pay the ransom. If you received a message from the scammer telling you that you have to pay for the safety of your data, just don’t respond and you won’t have to pay. The main reason why hackers breach your account is to get money. If he understands that you won’t pay, they’re more often than not going to leave you alone. But, if you’re still worried about the security of your data, you should contact your local law enforcement agency. Another reason why you mustn’t pay the ransom is that you indirectly promote the hackers' actions; you’re investing in their endeavour and stimulating their activity. Moreover, they might see you as a cash cow and try even harder to extort you in the future.

The next course of action in taking control over your account is changing your password. Indeed, use your noggin to figure out which sites may use the same password, and change those passwords too; it goes without saying that you shouldn’t reuse the same password on multiple websites. It’s also worth using a password generator to acquire new passwords, consisting of sophisticated alpha-numerical combinations that are naturally hard to guess.

In some instances, cybercriminals will anticipate these steps if they feel that their cover is blown, and they’ll beat you to changing your password. In this situation, you should contact the site’s support team to prove that you’re the true owner of the account. Sites such as Facebook will ask you to upload a proof of ID, for example. To prevent hacking from happening in the future, it’s worth taking advantage of the ability to link your email address and phone number to your account.

Recovering access to the account is time-consuming, as all the information ought to be checked manually. So, if you get in such trouble and find yourself waiting to get back your account, take some time to reflect on getting yourself a good-quality password manager that will eliminate the burden in the future. Hint hint.

Which words pop into your head when creating a password for your new account on a website or on a social network? Safety? Privacy? Well, there’s some bad news for you here — in our digital world, hackers are clued-up on hacking any kind of password that you can think into existence, and as a matter of fact, it’s a global problem. Users of the internet can never be sure that their accounts are protected enough to prevent data theft. Even global organizations such as Facebook can be the subject of cyber-attacks. And we mention the social giant for good reason too — in March 2020, the British company Comparitech stated that the data of more than 267 million people was leaked.

Ergo, it’s of paramount importance to know which techniques cybercriminals use to hack your password and steal your private information. There are a great number of methods that hackers can use to deceive people in order to steal private credentials and data. That’s why, today, we’re going through the most common techniques that can be used, so you’ll be in the know and much more secure online as a result.

1. Phishing

The easiest and most common way of hacking someone’s password is phishing. There are plenty of techniques here: phishing can take the form of an email, an SMS, a direct message on a social media platform, or a public post on a website. Cybercriminals spread a link or attachment that hooks an internet user in. Pushing leads a victim to a fake log-in page where he or she has to enter their data. After hacking, the hackers get a variety of data that can be used for any purpose. This way, people get their sensitive information served on a silver platter. As this technique is one of the oldest ones in the book, most users are aware of such a ploy. Almost everyone knows that following a suspicious link on the internet is a sure way of compromising yourself. Indeed, that’s why emails from unknown addresses tend to fall straight into the spam box and we’re used to blocking unknown numbers.

2. Social engineering

This type of cyberattack is based on the mistakes and imprudence that come as standard with the human brain. A criminal tricks the victim by acting like he or she is a real agent of an official company. It might be a fake call from your bank or some kind of technical support branch. You’ll likely be asked to provide confidential data so that the ‘agent’ may investigate ‘suspicious activity’ on your bank account. Usually, social engineering is mostly successful in manipulating pensioners due to their often dull mental blade and trusting nature. This technique is quite widespread and is much easier than creating an entire fake website to phish someone’s password.

3. Brute force attack

Brute force attacks are best characterized by the long, heavy method of checking each possible password variant. This way is really time-consuming, so most hackers use special software to automate the process. Most of the time, such attacks are based on knowledge gained from previous cracks as users often reuse their passwords on multiple websites and platforms. Also, cybercriminals might try lists of common variations of letters and numbers. That’s why, to protect yourself from such attacks, you should use as many symbols as possible and create passwords from unconnected words and unpredictable alpha-numerical compilations. Alternatively, you could use a password manager to automate this struggle (nudge nudge).

4. Dictionary attack

The dictionary attack partly resembles the previous method (brute force attack), the main idea of such a cyber attack is to submit all possible password variations by taking words from the dictionary. It makes the process of researching the right combination easier due to the strict structure of the dictionary. Moreover, it takes less time to crack the password If the hacker knows some sensitive information about the victim, like the name of their child, pet, or favorite color, for instance. Indeed, predictable human nature is the reason why this is such an effective method. To eliminate the possibility of such a cyberattack, it’s worth mixing semantically unconnected words, numerals, and other symbols. The best way, of course, is to get a password manager (nudge nudge).

5. Rainbow table attack

Passwords stored on the victim’s computer are usually encrypted. The plain text is replaced by various strings (hashes) to prevent data leaks. This method is named ‘hashing’. However, this method doesn’t guarantee that the password won’t be cracked; hackers are very familiar with such multi-layer security. The ‘rainbow table’ is a list of passwords and their hashes that have already been acquired through previous attacks. Hackers try to decrypt hashes by figuring out the correct combination based on different variations from the rainbow table. As a result, the password’s code may be retrieved from the database, removing the necessity to hack it. A good way to mitigate the risks of such an attack is to use software that includes randomly generated data in the password before hashing it.

6. Spidering

Many companies base their passwords on the names of the products they produce to help their staff remember the credentials that they need to access corporate accounts. Spidering is a type of cyberattack that uses this information to hack the company’s system and exploit the obtained information for malicious purposes. They surf the sites of organizations and learn about their businesses. Then, this knowledge is used to make a list of keywords that can be exploited in brute force attacks. As this process is quite time-consuming, experienced hackers utilize automatic software such as the infamous ‘web crawler’.

7. Malware

Malware is a harmful kind of software created to steal private information from the computer that it has been installed on. The victim gives access to his or her computer by clicking on a link specially made by cybercriminals. While this technique has various forms, the most common are keyloggers and screen scrapers that take a video of a user's screen or screenshots when passwords are being entered. They then send this data to the hacker. Some kinds of malware can encrypt a system’s data and prevent users from accessing certain programs. Others can look through users’ data to find a password dictionary that can be used in a variety of ways.

The amount of techniques being used by hackers to crack our passwords is increasing exponentially. The more ways there are to prevent break-ins, the more work hackers ought to do to get around them. That’s why, you should leave it to us, Passwork, your neighborly password managing wizards, to lift the burden from your shoulders.

If you've heard of ‘SHA’ in various forms but aren't sure what it stands for or why it's essential — you’re in luck! We'll attempt to shed some light on the family of cryptographic hash algorithms today.

But, before we get into SHA, let's go over what a hash function is and how it works. Before you can comprehend what SHA-1 and SHA-2 are, you must first grasp these principles.

Let's get started.

What Is a Hash Function?

A hash function relates to a set of characters (known as a key) of a certain length. The hash value is a representation of the original string of characters, however, it is usually smaller.

Because the shorter hash value is simpler to search for than the lengthier text, hashing is used for indexing and finding things in databases. Encryption employs hashing as well.

SHA-1, SHA-2, SHA-256… What’s this all about?

There are three types of secure hash algorithms: SHA-1, SHA-2, and SHA-256. The initial iteration of the algorithm was SHA-1, which was followed by SHA-2, an updated and better version of the first. The SHA-2 method produces a plethora of bit-length variables, which are referred to as SHA-256. Simply put, if you see “SHA-2,” “SHA-256” or “SHA-256 bit,” those names are referring to the same thing.

The NIST's Formal Acceptance

FIPS 180-4, published by the National Institute of Standards and Technology, officially defines the SHA-256 standard. Moreover, a set of test vectors is included with standardization and formalization to confirm that developers have correctly implemented the method.

Let’s break down the algorithm and how it works:

1. Append padding bits

The first step in our hashing process is to add bits to our original message to make it the same length as the standard length needed for the hash function. To accomplish so, we begin by adding a few details to the message we already have. The amount of bits we add is determined so that the message's length is precisely 64 bits less than a multiple of 512 after these bits are added. This can be expressed mathematically in the following way:

n x 512 = M + P + 64

M is the original message's length.
P stands for padded bits.

2. Append length bits

Now that we've added our padding bits to the original message, we can go ahead and add our length bits, which are equal to 64 bits, to make the whole message an exact multiple of 512.

We know we need to add 64 extra bits, so we'll compute them by multiplying the modulo of the original message (the one without the padding) by 232. We add those lengths to the padded bits in the message and get the complete message block, which must be a multiple of 512.

3. Initialize the buffers

We now have our message block, on which we will begin our calculations in order to determine the final hash. Before we get started, I want to point out that we'll need certain default settings to get started with the steps we'll be taking.

a = 0x6a09e667
b = 0xbb67ae85
c = 0x3c6ef372
d = 0xa54ff53a
e = 0x510e527f
f = 0x9b05688c
g = 0x1f83d9ab
h = 0x5be0cd19

Keep these principles in the back of your mind for now; all will fit together in the following phase. There are a further 64 variables to remember, which will operate as keys and are symbolized by the letter 'k.'

Let's go on to the portion where we calculate the hash using these data.

4. Compression Function

As a result, here is where the majority of the hashing algorithm is found. The whole message block, which is 'n x 512' bits long, is broken into 'n' chunks of 512 bits, each of which is then put through 64 rounds of operations, with the result being provided as input for the next round of operations.

The 64 rounds of operation conducted on a 512-bit message are plainly visible in the figure above. We can see that we send in two inputs: W(i) and K(i). During the first 16 rounds, we further break down the 512-bit message into 16 pieces, each consisting of 32 bits. Indeed, we must compute the value for W(i) at each step.

W(i) = Wⁱ⁻¹⁶ + σ⁰ + Wⁱ⁻⁷ + σ¹
where,
σ⁰ = (Wⁱ⁻¹⁵ ROTR⁷(x)) XOR (Wⁱ⁻¹⁵ ROTR¹⁸(x)) XOR (Wⁱ⁻¹⁵ SHR³(x))
σ¹ = (Wⁱ⁻² ROTR¹⁷(x)) XOR (Wⁱ⁻² ROTR¹⁹(x)) XOR (Wⁱ⁻² SHR¹⁰(x))
ROTRⁿ(x) = Circular right rotation of 'x' by 'n' bits
SHRⁿ(x)  = Circular right shift of 'x' by 'n' bits

5. Output

Every round's output is used as an input for the next round, and so on until just the final bits of the message are left, at which point the result of the last round for the nth portion of the message block will give us the result, i.e. the hash for the whole message. The output has a length of 256 bits.

Conclusion

In a nutshell, the whole principle behind SHA would sound something like this:

We determine the length of the message to be hashed, then add a few bits to it, beginning with '1' and continuing with '0' and then ‘1’ again until the message length is precisely 64 bits less than a multiple of 512. By multiplying the modulo of the original message by 232, we may add the remaining 64 bits. The complete message block may be represented as 'n x 512' bits after the remaining bits are added. Now, we split each of these 512 bits into 16 pieces, each of 32 bits, using the compression function, which consists of 64 rounds of operations. For the first 16 rounds, these 16 sections, each of 32 bits, operate as input, and for the next 48 rounds, we have a technique to compute the W(i). We also include preset buffer settings and 'k' values for each of the 64 rounds. We can now begin computing hashes since we have all of the necessary numbers and formulae. The hashing procedure is then repeated 64 times, with the result of the i round serving as the input for the i+1 round. As a result, the output of the 64th operation of the nth round will be the output, which is the hash of the whole message.

The SHA-256 hashing algorithm is now one of the most extensively used hashing algorithms since it has yet to be cracked and the hashes are generated rapidly when compared to other safe hashes such as the SHA-512. It is well-established, but the industry is working to gradually transition to SHA-512, which is more secure, since experts believe SHA-256 may become susceptible to hacking in the near future.

According to a survey conducted in February 2021, 46% of participants stated that on average, they spent five to six hours on their phone on a daily basis.

That means for almost half of you, a quarter of your life’s security will be dictated by your choice of mobile platform. However, how safe are these popular phone platforms? Because mobile devices have grown to be so important and pervasive in people's lives, they have piqued the interest of criminal hackers looking to steal your personal information.

The technology itself is always advancing, and that’s why we’re not looking to compare specific Android or iOS versions today, but rather the core principles and philosophy behind Apple and ‘the rest’ — which importantly, have consequences in terms of privacy and security.

Let’s start with the most common threat.

App Control

Usually, when it comes to installing an app, there is only one common method to do it — via a specific Store — for example, Google Play or the AppStore. On both platforms, the uploaded application will next go through an app review procedure to verify that it is not dangerous and does not breach any developer policies.

These rules are designed to guarantee that the app's content is suitable, that it doesn't copy other applications or people, that it follows monetization standards, and that it meets the minimum functionality criteria (it should not crash all the time, and it should respect the user experience, for instance).

The problem is that employees tasked with determining whether applications meet particular requirements may be unaware of what the app actually does with personal data. The number of Android and iOS applications (as well as their creators) is constantly growing, and as a consequence, corporations have had to recruit more reviewers in recent years.

And we all know what happens when a firm adds thousands of people all at once: the learning management system becomes difficult to scale, and not all employees are effectively onboarded.

As far as we can tell, the greatest difference in approach is that Apple has actual people checking each app 100 percent of the time, while Google attempts to automate this process as much as possible — and it consistently causes difficulties for them.

According to a report issued in November 2020 by the NortonLifeLock Research Group, between 10% and 24% of 34 million apps scattered over 12 million Android devices might be classified as harmful or possibly undesired apps, depending on your classifications.

Of those applications, 67% were installed from the Google Play Store. The researchers mention that:

"The Play market is the main app distribution vector responsible for 87% of all installs and 67% of unwanted installs”

So, if you’re a person that loads tons of apps while searching for “the perfect one” — consider deleting the underdogs — the fewer apps you have on your phone, the better.

Permission control and telemetry

The most serious danger to your mobile security comes from apps that request too many access permissions and subsequently leak your information.

While the app store is mostly responsible for filtering out malware riffraff that affects a disproportionate number of Android users, iPhone users are not immune to assaults.

And what we mean is that while most iOS users believe they are secure, they are not. First and foremost, when an app gains access to, say, 'All photos,' few users realize that the app may load all of your images in the background, use machine learning to find NSFW content, and discreetly submit it all to a server. Moreover, you won't get the cool camera access dot appearing if the app does that.

Furthermore, even if you disable all of the app's permissions, the app may still gather and monitor a range of data. Every app can monitor 29 highly detailed data points about your iPhone, according to an examination by researchers at privacy software firm Lockdown and The Washington Post, including your IP address, free storage, your current volume level (to 3 decimal points), and even your battery status (to 15 decimal points).

But what about Android?

Well, we have bad news for its consumers as well: according to a study undertaken by Douglas Leith of Trinity College Dublin, Google gathers more than twenty times the amount of data from a typical Android device than Apple does from an iPhone.

This observation remains true even when a user has specifically opted out of telemetry collection. Every 4.5 minutes, both Android and iOS devices send data to Google and Apple's servers, and there's nothing you can do about it as a user.

According to these researchers, smartphones with default privacy settings communicate information such as the IMEI, SIM serial number, phone number, hardware serial number, location, cookies, local IP address, neighboring Wi-Fi MAC addresses, and even the advertising ID.

Both companies, by the way, disagree with the results, claiming that they just expose what is required to keep phones functioning properly.

Updates

Keeping your phone's operating system up to date is the simplest approach to keeping it safe. Updates aid in the mitigation of software vulnerabilities, which are a kind of security flaw detected in an operating system. Hackers make use of this flaw by building code that targets a particular vulnerability, which is often packaged as malware. Simply visiting a website, reading a compromised email, or playing malicious media might infect your smartphone. This is what occurred when the bank credentials of 300,000 Android users were exposed by regular applications on the Google Play store.

When it comes to transmitting upgrades to your palm, Apple still has the manufacturing infrastructure, carrier network contracts, and underlying programming in place to make it happen quickly and painlessly. While some consumers continue to complain about iOS' famed lack of customization, Apple's well-policed walled garden has also ensured that iPhone users are essentially impervious to viruses without even realizing it.

Google, on the other hand, still can’t fix the Android update problem.

Because each Android smartphone has its own hardware, when Google pushes an update, it may take up to a year for other smartphone makers to upgrade their devices, and that's only if they intend to do so. Other Android phones, apart from the Google Pixel series, seldom get all upgrades for an extended period of time — and there are various reasons for this. The first factor to evaluate is the number of models available from each manufacturer. Apple only adds around four iPhones to its portfolio per year, so the total number of iOS devices it needs to support is quite modest when compared to that of android — which is why the 7-year-old iPhone 6s is still getting the latest upgrades in 2022.

Conclusion

The most significant distinction between iOS and Android in terms of security and safety is their ideology. Because iOS is a closed ecosystem, it is entirely under Apple's control when it comes to security. The reason is that, as far as we know, Apple does not gain profit from advertisements (apart from program advertisements in the AppStore), hence it is not interested in gathering and selling your data to third parties.

Google, on the other hand, earns the majority of its revenue from advertisements, which implies that its success is dependent on its ability to target its adverts as precisely as possible. Even though Android is a free and open-source operating system, the Google Play Services that gather data are not.

In the end, Android has a lower degree of security out of the box, but custom Android versions may give a high level of protection.

Why do you actually need a VPN?

Virtual Private Networks (VPNs) encrypt your data and hide your online activity from third parties, allowing you to surf the web anonymously.

Web servers collect information about your computer's IP address and other information about your browsing history when you visit a website that is hosted on their servers. Your data is scrambled and far more difficult for third parties to monitor when you use a VPN that first connects to a private server.

Consumer VPNs are mostly used for anonymous web surfing. Some people can also use a VPN at home to connect to computers and files on your local network from a different place.

What are the possibilities of using a VPN?

Because a VPN alters your Internet Protocol (IP) address, it may perform a wide range of functions. When a computer is linked to the internet, it has a unique IP address that notifies other computers where it is situated. When you use a VPN, you first connect to a remote computer (a server) to fool other computers into thinking you're in a different place. When using a virtual private network, it is possible to choose a fake location for yourself.

PrivacyJournal offers reviews of the best VPN providers out there.

There are many options available to you when you get a new IP address. The material available on streaming services like Spotify and Netflix, for example, can change. Using a VPN allows you to access streaming libraries in other countries.

A VPN may also be used to circumvent censorship. A practice known as geo-blocking may be used by certain government agencies to ban websites and services in certain regions or territories. Through the use of a VPN, you may cultivate the illusion that you’re in a different place, masking your real IP address and as a result, accessing restricted media.

In terms of the ‘dark side’, individuals use VPNs to download copyrighted material and engage in other illicit actions online as there is an obfuscation of responsibility.

Does a VPN provide ultimate privacy?

Encryption is a crucial component of a VPN. All you need to know about encryption is that it scrambles your data so that only the right key can decode it. We'll go into more detail about encryption in the following section. To put it another way, it's a deadbolt lock for your computer's hard drive.

Before it reaches the internet, all of your data travels via an encrypted tunnel, where it is inaccessible to everyone else. As a result, when you visit a website, your browser does not transmit any information along with it. Browsers carry a lot of data, like your time zone, language, operating system, and even your screen resolution.

Although none of this data directly identifies you, the full collection is likely unique to you and may be used to identify you via a technique known as browser fingerprinting. Government authorities, marketers and hackers may use this information against you.

A VPN conceals all of your browser information, as well as your browsing history. While you’re connected, no one, even your internet service provider, can tell what you’re doing online.

A VPN isn’t a one-stop-shop for internet privacy, however. Anything you do while connected to the internet is fair game, including websites you log into and services you utilize. Many browsers utilize an account to move information like your browsing history and cookies between devices. This data isn’t safeguarded by your VPN tunnel, either.

How does it work?

VPNs provide an additional layer of protection for your online activity. As previously stated, using a private VPN server enables you to mask your IP address and make it look as if you're connected to the open internet via a different location.

All of this is possible because of VPN protocols, which are used by VPN service providers. VPN protocols are simply a set of instructions for your computer to follow while connecting to a server. The protocol also specifies encryption requirements in addition to a ‘how to’ of setting up and managing your connection.

Encryption is a major reason to use a VPN. All but a small percentage of web surfing now takes place in a secure environment. Despite the fact that you're using an encrypted connection, your personal information is still being sent.

Think of your internet connection as a passageway through which you move information. In order to keep your online activities private, this tunnel is protected by a layer of encryption. Whenever you connect to your Twitter account, for example, you're doing it over a secure tunnel that only you and Twitter can see.

As with a VPN, this is the case. Instead of directly connecting to the internet, your data is routed via a VPN server, where it is encrypted and rendered anonymous. The AES cipher with a 256-bit key is used by most VPN services. AES is a widely used block cipher for encrypting and decrypting data.

By establishing an encrypted connection, the VPN server verifies that you are indeed connected to a certain private network. Data and browser history are then shielded from prying eyes outside the tunnel and never leave it.

To summarize, a VPN creates an encrypted path for your data to travel through on its way to and from the VPN server. In most cases, there’s no way for anybody to know who you are or where you’re from when connected to a VPN server.

Is it a panacea?

When it comes to the effectiveness of VPNs, there's no secret sauce. A renowned VPN service like NordVPN or TorGuard is all you need to ensure that your VPN works. Individual product evaluations are of course necessary.

There's a short test you can do to determine whether your VPN connection is functioning. For free, ipleak.org and ipleak.net provide tools for checking your IP address, DNS queries, and WebRTC data (basically, everything a VPN should, in theory, obfuscate). Verify that the information is different when your VPN is active. As long as it is, your VPN is running as it should.

Since the dawn of the internet, the world of chat programs has seen drastic transformations. Given that not that much time has passed since the creation of the first chat app — CompuServe's CB Simulator — the rate of progress and development is quite astounding.

Chat protocols and frameworks are the subject of this article, and we're going into great detail about everything from their history to their security issues. At Passwork, we’re also very interested in the security solutions that are intertwined with these chat protocols, so without further ado, let’s explore the most popular ones:

WebRTC — Web Real-Time Communication

Using WebRTC, you may participate in rich, real-time multimedia conversations. Most web-based video and audio chat systems need you to download third-party plugins or applications. As a result, most browsers already have WebRTC, which utilises APIs to link peers. As an open-source initiative developed by Google, WebRTC enables real-time communication in your web browser.

By default, WebRTC uses UDP (the User Datagram Protocol). However, if there is a firewall between the two devices, WebRTC is able to use TCP (the Transmission Control Protocol).

When it comes to WebRTC, it’s primarily used to provide an immersive multimedia experience without the requirement for third-party applications or services.

Direct and unmediated communication with your consumers is one of the main advantages of WebRTC. If you're looking for complete control over customer communication channels, this is the ideal solution for you. As an additional bonus, there is no rate limit or price adjustments due to the absence of a third-party provider.

To construct a chat solution using WebRTC, you'll need access to a developer who is familiar with the technology.

Discord, Google Hangouts, and Facebook Messenger are just a few of the numerous chat apps that make use of WebRTC.

Security:

WebRTC enforces or supports essential security practises in all major areas since it was, after all, created with security in mind. As a result, in addition to being made safe, it encourages WebRTC developers to take security seriously as well.

WebRTC is now considered by some to be one of the most secure VoIP technologies available as a consequence of a significant emphasis on secure communication. The basic idea of having encryption enabled by default is that a call is always private. Encryption and security are no longer regarded as optional features. To top it off, WebRTC is open source, making it a compelling and dependable platform on which developers may wish to construct their next product.

Of course, we anticipate a rise in the number of communication services that provide significantly enhanced security to their consumers in the near future. But, for the time being, WebRTC is one of the frontrunners.

WebSocket

WebSocket, one of the most widely used communication protocols, establishes a low-latency, near-real-time connection between the client and the server via the use of sockets. As it aims to achieve the lowest latency feasible, it is most often utilised for online gaming, chat apps and the real-time updating of social feeds, for example.

In contrast to a standard HTTP system, in which communication may only be started by the client, a WebSocket connection allows communication to take place both ways. The WebSocket API is supported by all current browsers, and data is transferred through a TCP port, similar to the HTTP protocol.

When a series of conversations around the inclusion of a TCP-based socket API in the HTML5 standard began in June 2008, WebSocket was one of the ideas that emerged.

WebSocket is a technology that is used by many websites that demand real-time updates. WebSocket is used by several large chat apps, such as Slack, as part of their technology stack.

Security:

WebSocket as a technology has some inherent security issues:

• WebSocket permits an infinite number of connections with the target server, resulting in the server's resources being depleted as the result of a DOS attack;
• WebSockets may be utilised over unencrypted TCP channels, which can expose sensitive data to serious defects like those described in the OWASP Top 10 A6-Sensitive Data Exposure list;
• WebSockets are subject to malicious input data assaults, resulting in Cross-Site Scripting attacks (XSS).

XMPP: Extensible Messaging and Present Protocol

With the launch of Jabber in 1999, Jeremie Miller brought XMPP to the world.

XMPP is a protocol for sending XML (Extensible Markup Language) data over the internet. It facilitates real-time communications by improving the push method between clients. XMPP aims to create a network of linked devices that can communicate with one another using their own trusted servers.

It's a cross-platform protocol that can be used with the XMPP client on the Web, Android, and iOS platforms. The enormous number of open-source and free clients is one of XMPP's distinctive selling advantages, allowing for a very simple installation procedure.

Instant messaging, multi-party conversations, content dissemination, and multimedia streaming, such as audio and video calls, are all examples of the protocol’s applications. Many big chat programs, such as WhatsApp and Zoom, employ XMPP.

Google Talk, ICQ, and Cisco Meeting provide excellent illustrations of what can be accomplished when using an XMPP client.

Security:

XMPP has had its security vetted by the experts at the IETF, and so has native support for pluggable authentication (via SASL) and leading-edge security (via TLS).

Still, that doesn’t stop some hackers from finding vulnerabilities:

An unauthenticated, remote attacker might utilise a vulnerability in the Cisco Meeting Server software's Extensible Messaging and Presence Protocol (XMPP) capability to create a denial of service (DoS) scenario for users of XMPP conferencing apps. The flaw is caused by XMPP packets that haven't been properly validated. An attacker could take advantage of this flaw by sending specially crafted XMPP packets to a vulnerable device, or even by inducing process crashes and denial-of-service scenarios in XMPP conferencing apps — either way, it's not great for the users.

If the concept of ‘quantum cryptography' sounds complicated to you, you're right. That’s why this ‘encryption tutorial for dummies’ shall demystify the concept and provide an explanation in layman’s terms.

Quantum cryptography, which has been around for a few decades, is becoming more and more important to our daily lives because of its ability to protect essential data in a manner that conventional encryption techniques cannot.

What is it?

Cryptography, as we all know, is a technique that aims to encrypt data by scrambling plain text so that only those with the appropriate ‘key’ can read it. By extension, quantum cryptography encrypts data and transmits it in an unhackable manner using the principles of quantum mechanics.

While such a concept seems straightforward, the intricacy resides in the quantum mechanics that underpin quantum cryptography. For example:

• The particles that make up the cosmos are fundamentally unpredictable, and they may exist in several places or states of existence at the same time;
• A quantum attribute cannot be measured without causing it to change or be disturbed;
• Some quantum attributes of a particle can be cloned, but not the whole particle.

How does it work?

Theoretically, quantum cryptography operates by following a model that was first published in 1984.

Assume there are two people called Alice and Bob who want to communicate a message in a safe manner, according to the model of quantum cryptography. Alice sends Bob a key, which serves as the signal for the communication to begin. One of the most important components is a stream of photons that go in just one direction. Each photon corresponds to a single bit of data — either a 0 or a 1 — in the computer's memory. However, in addition to traveling in a straight path, these photons are oscillating, or vibrating, in a certain fashion as they move.

The photons pass via a polarizer before reaching Alice, the sender, who then commences the transmission. When some photons pass through a polarizer with the same vibrations as before, and when others pass through with different vibrations, the filter is said to be ‘polarized’. There are many polarization states to choose from, including vertical (1 bit), horizontal (0 bit), 45 degrees right (1 bit) and 45 degrees left (0 bit). In whatever system she employs, the broadcast has one of two polarizations, each encoding a single bit, which is either 0 or 1.

From the polarizer to the receiver, the photons are now traveling via optical fiber to Bob. Each photon is analyzed using a beam splitter, which determines the polarization of each photon. After receiving the photon key, Bob does not recognize the right polarization of the photons, so he chooses one polarization at random from a pool of available options. Alice now compares the polarizers Bob used to polarize the key and informs Bob of the polarizer she used to deliver each photon to the receiver. Bob checks to see whether he used the right polarizer at this point. The photons that were read with the incorrect splitter are then eliminated, and the sequence that is left is deemed the key sequence.

Let's pretend there is an eavesdropper present, who goes by the name of Eve. Eve seeks to listen in and has the same tools as Bob in order to do so successfully. However, Bob has the benefit of being able to converse with Alice in order to check which polarizer type was used for each photon, but Eve does not. Eve is ultimately responsible for rendering the final key.

Alice and Bob would also be aware if Eve was listening in on their conversation. After Eve observes the flow of photons, the photon locations that Alice and Bob anticipate to see will be altered as a result of her observations.

Well, that’s all pretty mind-blowing, but for us, the general public, the biggest question is…

Is it really used?

Although the model described above has not yet been fully developed, there have been successful implementations of it, including the following:

• The University of Cambridge and the Toshiba Corporation collaborated to develop a high-bit-rate quantum key distribution system based on the BB84 quantum cryptography protocol;
• DARPA's Quantum Network, which operated from 2002 to 2007, was a 10-node QKD (Quantum Key Distribution) network constructed by Boston University, Harvard University, and IBM Research. It was operated by the Defense Advanced Research Projects Agency;
• Quantum Xchange created the first quantum network in the United States, which is comprised of over 1,000 kilometers of optical fiber;
• The development of commercial QKD systems was also carried out by commercial businesses such as ID Quantique, Toshiba, Quintessence Labs, and MagiQ Technologies Inc.

As you can see, these rare implementations are pretty far from what you’d expect to use every day. But hopefully, that will change in the near future.

The pros and cons of quantum cryptography

As with any developing technology, the state of it now (2022), may be very different to its state in the future. Thus, the following table may change dramatically. We do believe, however, that we’ll see fewer points in the ‘Limitations’ column as the years go on.

The need for unbreakable encryption is right there staring us down. The development of quantum computers is on the horizon, and the security of encrypted data is now in jeopardy due to the threat of quantum computing. We are fortunate in that quantum cryptography, in the form of QKD, provides us with the answer we need to protect our information long into the future — all while adhering to the difficult laws of quantum physics.

I’d like you to reflect on your personal interactions when it comes to the internet. Consider the impact that the internet has had on society. Have these two things changed with time? Of course. Indeed, with more social media platforms and apps for mobile devices than ever before, we’ve yet another fundamental transition on the horizon…

The Web's Evolution

The web has developed a lot over the years, and its applications are nearly unrecognizable. Web 1.0, Web 2.0, and Web 3.0 are often used as benchmarks to describe the web's progression.

Web 1.0

Web 1.0 was the original web. Most participants were content consumers, while producers were mostly web developers who built websites with mostly text or graphic material. Web 1.0 ran from 1991 until 2004. Web 1.0 sites served static material rather than dynamic HTML. Sites had little to no interactivity and data was supplied through a static file system rather than a database. Web 1.0 is the ‘read-only’ web.

Web 2.0

Most of us have only used the web in its present incarnation (Web2). Web2 is the social and interactive web. You don't have to be a developer to create in the Web2 universe. Many applications are designed so that anybody may create. You can create and share a concept with the world. You can also post a video for millions of others to see, connect with your viewers, and comment on the video itself. Web2 is easy, and because of that, more and more individuals are becoming content creators. The web as it is now is fantastic in many aspects, but there are still several issues.

Privacy and security

Web2 applications are plagued by data breaches on an almost daily basis. If you want to know when your personal information has been leaked, there are websites devoted to keeping track of these incidents and alerting you.

Your data and how it is handled are completely out of your hands when it comes to Web2. When it comes to tracking and storing user data, many organizations do so without their customers' permission. The firms in charge of these platforms then possess and manage all of this data. Also at risk are users who reside in nations where exercising one's First Amendment rights might have unintended repercussions. Authorities often take down sites or confiscate funds if they suspect someone is disseminating information contrary to the official line. Governments can easily interfere, control, or shut down programs using centralized servers. By the same token, banks are digital and under centralized control — governments typically meddle in this area as well. During times of volatility, severe inflation, or other kinds of political instability, they have the ability to close bank accounts or restrict access to cash.

By starting from the bottom up, Web3 seeks to fix many of these flaws by reimagining how we design and interact with the internet and entities within it.

What exactly is Web 3.0?

Web2 and Web3 differ in a few ways, yet decentralization is a common theme in both. Web3 adds a few new features to the internet that we already use. It can be defined as the following:

• Verifiable
• Trustless
• Self-governing
• Permissionless
• Distributed and robust
• Stateful
• With built-in payments

When working with Web3, programmers seldom create and deploy applications that rely on a single server or database (usually hosted on and managed by a single cloud provider).

Instead, Web3 applications either run on blockchains, decentralized networks of many peer to peer nodes (servers), or a combination of the two that forms a crypto-economic protocol.  Many people in the Web3 community refer to these applications as "dapps" (decentralized apps), a word that you’ll see swimming around quite often.

An incentive for network members (developers) to deliver the best service possible is a key component of a robust and secure decentralized network.

Web3 is often discussed in conjunction with cryptocurrencies. This is due to the fact that many of these protocols rely heavily on cryptocurrencies. Anyone who wishes to become involved in one of the projects is given tokens (a cash incentive) in exchange for their time and effort.

In the past, cloud providers offered a wide range of services, including computation, storage, bandwidth, identity, hosting, and other online services.

Participating in the protocol in a variety of ways, both technical and non-technical, might be a source of income.

The protocol is often paid for by users in the same way that a cloud service provider like AWS charges its customers today. In Web3, however, the money flows directly to the network members. The elimination of middlemen that are both unneeded and inefficient is a hallmark of this sort of decentralization.

There are utility tokens provided by several online infrastructure protocols including Filecoin, LivePeer, Arweave, and The Graph. Many tiers of the network are rewarded with these tokens. This is how even native blockchain systems like Ethereum work.

How Web3 Handles Identity and Privacy

Here, at Passwork, security is paramount. This is where, technically, Web3 shines the most. Identity is handled quite differently within Web3. The wallet address of the user engaging with the app is usually used to link identities in Web3 applications. This means that wallet addresses, unlike Web2 authentication methods like OAuth or email + password, are fully anonymous until the user wishes to publicly link their identity to it.

It is possible for a user to build up their reputation over time if they choose to use the same wallet for various decentralized applications (dapps).

Authentication and identification layers may be replaced with self-sovereign identity protocols and tools like Ceramic and IDX. An RFP for a "Sign in with Ethereum" standard is currently being worked on by the founders of Ethereum.

Conclusion

Web 3.0's set of capabilities has the potential to fundamentally alter the way we see and utilize the internet, giving people more agency, spawning new sectors, and enabling networks to operate without a centralized authority or single point of failure. It’s just a matter of time until Web 3.0 becomes the new global standard.

As far as answering the question raised in the title — on paper, Web3 should eliminate most of the privacy and security issues faced with Web2. In practice — this is still not yet certain.

Most of us have heard of torrents, and have likely also used torrents to download movies, books, music, TV shows, games, and so on. But, you’ve probably still got one question that remains unanswered — what are they? BitTorrent is well-known as a technology for piracy, although its genius isn’t limited to that. It's a useful, decentralized peer-to-peer protocol that outperforms other protocols in many different ways.

In this article, we’ll break it down to be as simple as possible while also explaining several terms that might pass you by every day.

Why do I need BitTorrent?

When you download data from the internet, most of the time, your computer connects to the webserver and immediately downloads the data from a certain server. This is how the cohort of online traffic operates. Even though we have fancy technologies to reroute this traffic through many different servers, there’s still a bottleneck in terms of the maximum speed that may be provided to the end-user. But what if you know someone who already has the file that you need, wouldn’t it be better to AirDrop it, instead of uploading it to a server, and then downloading it once again? Well, that’s what Bram Cohen created his BitTorrent protocol for.

How does BitTorrent work?

BitTorrent is effectively a peer-to-peer protocol, which means that computers in a BitTorrent ‘swarm’ (a collection of computers downloading and uploading the same torrent) exchange data without the use of a central server.

A machine traditionally joins a BitTorrent swarm by loading a .torrent file onto a BitTorrent client. The BitTorrent client communicates with a ‘tracker’ defined in the .torrent file. The tracker is a dedicated server that keeps track of the computers that are linked to it. The tracker exchanges IP addresses with other BitTorrent clients in the swarm, allowing them to communicate with one another. That’s exactly why it is called a ‘tracker’ — it tracks the participants of any given communicative endeavour.

Once connected, a BitTorrent client downloads tiny chunks of the torrent's contents, in fact, as much as it can. As soon as the BitTorrent’s client has any data downloaded, it may start uploading it to other BitTorrent clients in the swarm. As a result, everyone who downloads a torrent is also uploading the same torrent — all the pieces that a user has at the moment. This increases the download speed for everyone. When 10,000 users download the same file, the central server is not overburdened. Instead, each downloader shares their upload capacity with other downloaders, ensuring that the torrent remains as fast as possible.

Importantly, BitTorrent clients never download files directly from the tracker. The tracker simply participates in the torrent by keeping track of the BitTorrent clients that are connected to the swarm, not by downloading or uploading data.

‘Seeds’, ‘Peers’, and ‘Leeches’

If you're a torrent user, you've probably come across the words ‘seeds’, ‘peers’, and ‘leeches’. Let's take a look at what these terms actually mean.

The seed is the user who has already downloaded the entire file and is now sharing it with peers while not downloading any parts of the file from others. To download a torrent, one seeder – who has a full copy of all the files in the torrent — must first join the swarm so that other users may download the data. If a torrent has no seeders, it cannot be downloaded since no connected user possesses the entire file.

Leechers or peers are people who are simultaneously downloading and uploading — so, the vast majority, basically. In the BitTorrent world, people who give more — get more. In other words, the BitTorrent client prefers to send data to clients who contribute more upload bandwidth rather than sending data to clients who upload at a very slow speed.

This improves download rates for the whole swarm and compensates those who donate more upload bandwidth.

Moreover, we bet you encountered times when the file you wished to download via the torrent network wasn’t very popular, resulting in low speeds, or no download at all. This could have resulted, for example, because all the seed users were offline. It’s good to know that our ability, as highly-evolved primates, to create new technologies is limitless. Indeed, as a result, we did manage to mitigate the aforementioned, to an extent.

Magnet links

Apart from the .torrent file, you might be familiar with something called ‘magnet links’.

A magnet link includes a unique identifier, different data based on the torrent's exact nature, and, most significantly, a cryptographic hash of the torrent’s contents. And that’s really cool because you can search for different torrents that lead to the same file. Now, a magnet link uses that identifier to ‘attract’ all torrents that can help download those files, meaning more seeders, meaning more peers, meaning greater speeds and stability! All this fancy technology is done by what is called the DHT protocol, and according to its specification, "each peer effectively becomes a tracker." This implies that BitTorrent’s clients no longer require a centralized server to manage a swarm. Rather, BitTorrent evolves into a completely decentralized peer-to-peer file-sharing system.

Does this have applications outside of PirateBay?

Of course. Here are just some examples:

• To deliver updates for games, including World of Warcraft, StarCraft II, and Diablo 3, Blizzard uses a special BitTorrent client. This enhances everyone's downloads by allowing users to share their upload bandwidth with others, utilizing idle bandwidth ensuring quicker downloads for everyone;
• Wikileaks released files using BitTorrent, which relieved the tremendous strain on their systems;
• BitTorrent is used by Linux distributions to help disseminate ISO disc images.

Is it safe?

A big problem is that virus-ridden pirated content makes up a concerning chunk of all available torrents nowadays; that’s a huge threat to your security for obvious reasons. However, the biggest problem with torrents is that all BitTorrent users may see the ISP addresses of all users as well as the data they send. And of course, copyright holders, the police, advertising organizations, and hackers frequently monitor this data. Because of this, it’s critical for torrent users to maintain total online security by utilizing internet security software and installing operating system updates as soon as they become available. Encrypting an internet connection and masking the IP address with a virtual private network (VPN) also helps, but not to a full extent. So the short answer is — it’s not very safe.

In the end, downloading via BitTorrent is worth it, most of the time, especially when it comes to big files. While lacking in security, BitTorrent is the Web2 version of Web3 that we’re all allowed to try right now, as long as it doesn’t infringe on copyright laws.

Despite the fact that Wi-Fi is a trademark owned by the Wi-Fi Alliance, an organization committed to certifying that Wi-Fi equipment fulfills the IEEE's set of 802.11 wireless standards, the name ‘Wi-Fi’ is associated with wireless access in general nowadays.

These specifications, which include 802.11b (pronounced "Eight-O-Two-Eleven-Bee," omitting the "dot") and 802.11ac, are part of a family of specifications that began in the 1990s, which is still growing today. Improvements to wireless speed and range, as well as the usage of additional frequencies as they become available, are codified in the 802.11 standards.

What do those standards represent?

The IEEE 802.11 standard is a collection of technological advancements that have been created over a long period of time. Each new breakthrough is specified by a one- or two-letter suffix to "802.11," which represents the modification to the standard. Only the 2.4-GHz band was supported by the initial 802.11 standard, which allowed for speeds of up to 2 Mbps. New coding algorithms were implemented to 802.11b to enhance the speed to 6 Mbps. 802.11a included 5-GHz support and Orthogonal Frequency Division Multiplexing (OFDM) coding techniques, boosting speed to 54 Mbps. The 802.11g standard brought OFDM from the 802.11a standard to the 2.4-GHz range. 802.11n introduced a slew of high-throughput enhancements that increased throughput by a factor of ten, allowing high-end business access points to reach signaling throughputs of 450 Mbps.

As you may have noticed, the IEEE naming method for the standard is a little confusing, so the Wi-Fi Alliance has come up with some shorter names to make it easier to comprehend.

The alliance refers to 802.11ax Wi-Fi as Wi-Fi 6 — the current emerging standard. Wi-Fi 5 is now 802.11ac, while Wi-Fi 4 is now 802.11n. According to the Wi-Fi Alliance, the goal is to make it easier for the end-user to navigate through the myriads of routers and client devices.

Meanwhile, it's crucial to note that the Wi-Fi Alliance hasn't come up with new names for all of the 802.11 standards, so familiarity with the old ones is essential. Furthermore, the IEEE, which is still working on further versions of 802.11, has not accepted these new names, making it more difficult to find out information about them using the new names.

How secure is it?

The authentication security protocols defined by the Wireless Alliance, such as Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA), are used to secure wireless security. There are now four wireless security protocols available:

• Wired Equivalent Privacy (WEP);
• Wi-Fi Protected Access (WPA);
• Wi-Fi Protected Access 2 (WPA 2);
• Wi-Fi Protected Access 3 (WPA 3).

To be sure your network is secure, you must first identify which network yours falls under.

WEP

The first security protocol to be implemented was Wired Equivalent Privacy (WEP). It was designed in 1997 and is now outdated, however, it is still used with older devices in present times.

WEP employs a data encryption technique based on a mix of user and system-generated key values. However, hackers have devised strategies for reverse-engineering and breaking the encryption mechanism, making WEP the least secure network type.

WPA

The Wi-Fi Protected Access (WPA) protocol was created to address the weaknesses in the WEP protocol. WPA includes features like the Temporal Key Integrity Protocol (TKIP), a dynamic 128-bit key that proved more difficult to crack than WEP's static, unchanging key.

It also had encryption features like the Message Integrity Check, which looked for any tampered packets transmitted by hackers and the Pre-shared key (PSK), among others.

As detailed in this article, both WEP and WPA are very hackable, so please, take our advice and never use them.

WPA2

WPA2 introduced substantial updates and new features to the wireless security gambit in 2004. WPA2 substituted TKIP with the Counter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP), which is a significantly more sophisticated kind of encryption technology.

Since its creation, WPA2 has represented the industry standard; on March 13, 2006, the Wi-Fi Alliance specified that any future products using the Wi-Fi trademark must employ WPA2.

WPA2-PSK

To connect to a wireless network, WPA2-PSK requires only one password. It's often assumed that using a single password to access Wi-Fi is safe, but only if you trust the people who use it. This is obviously not very secure, considering the fact that this key may fall into wrong hands. As a result, this protocol is most commonly used for home or open Wi-Fi networks.

To encrypt a network with WPA2-PSK, you ought to provide your router with a plain-English password between 8 and 63 characters long, rather than an encryption key. CCMP is used to create unique encryption keys for each wireless client using that passcode and the network SSID. Moreover, the encryption keys are updated on a regular basis.

WPA3

WPA3 is the most recent (and improved) version of WPA2, which has been in use since 2004. In 2018, the Wi-Fi Alliance began certifying WPA3-approved equipment.

Although WPA3 is more secure than WPA2, the Wi-Fi Alliance will continue to maintain and enhance WPA2 for the foreseeable future. When compared to WPA2, WPA3 includes the following noteworthy features:

• Stronger brute force attack protection: WPA3 defends against offline password guesses by allowing only one guess per user and forcing them to engage directly with the Wi-Fi equipment, requiring them to be physically present each time they wish to guess the password. In public open networks, WPA2 lacks built-in encryption and privacy, making brute force attacks a significant danger;
• Simultaneous Authentication of Equals protocol (SAE): This protocol is used to provide a secure handshake between a network device and a wireless access point, in which both devices interact to verify authentication and connection. Even if a user's password is weak, WPA3 uses Wi-Fi DPP to give a more secure handshake;
• Individualized data encryption: When connecting to a public network, WPA3 uses a mechanism other than a shared password to sign up a new device. WPA3 employs the Wi-Fi Device Provisioning Protocol (DPP), which allows users to let devices onto the network via NFC tags or QR codes. WPA3 security also employs GCMP-256 encryption instead of 128-bit encryption.

WPA3 functionality will not be extended to all devices automatically. Users who want to use WPA3-approved devices must either purchase new routers that enable WPA3 or hope that the device's manufacturer implements updates to support the new protocol.

We, at Passwork, highly recommend using the latest security protocols while constantly updating your router’s firmware. When you ignore critical updates, you risk exposing holes in your security that allow hackers to take control of your network. Use sophisticated and long passwords at all times. Even if we’re talking about your home Wi-Fi network – remember, if your password is ‘12345678’, your neighbours can easily hack into your network and spoof the data.

End-to-end encryption has been introduced by many communication providers in recent years, notably WhatsApp and Zoom. Although those companies have tried to explain the concept to their user base several times, we believe they failed. Whilst it's clear that these platforms have increased security, most don’t know how or why. Well, encryption is a rather simple concept to understand: It converts data into an unreadable format. But what exactly does "end-to-end" imply? What are the advantages and disadvantages of this added layer of security? We'll explain this as simply as possible without diving too much into the underlying math and technical terminology.

What is end-to-end encryption?

End-to-end encryption (E2EE) is a state-of-the-art protocol for communication security. Only the sender and the intended recipient(s) have access to the data in an end-to-end encrypted system. The encrypted data on the server is inaccessible to both hackers and undesirable third parties.

End-to-end encryption is best understood when compared to the encryption-in-transit approach, so let’s perform a quick recap. If a service employs encryption-in-transit, it is usually encrypted on your device before being delivered to the server. It’s then decrypted for processing on the server before it’s re-encrypted and routed to its final destination. When the data is in transit, it’s encrypted, but when it’s ‘at rest’, it’s decrypted. This safeguards the data during the most dangerous stage of the journey, transit — when it’s most exposed to hackers, interception, and theft.

End-to-end encryption, on the other hand, is the process of encrypting data on your device and not decrypting it until it reaches its destination. When your message travels through the server, not even the service that is delivering the data can view the content of your message.

In practice, this means that messengers using 'real' end-to-end encryption, like Signal, know only your phone number and the date of your last login – nothing more.

This is important for users that want to be sure their communication is kept secure from prying eyes. There are also some real-life examples that utilize end-to-end encryption for financial transactions and commercial communication.

How does it work?

The generation of a public-private key pair ensures the security of end-to-end encryption. This method, also known as asymmetric cryptography, encrypts and decrypts the message using distinct cryptographic keys. Public keys are widely distributed and are used to encrypt or ‘lock’ messages. Only the owner has access to the private keys, which are needed to unlock or decrypt the communication.

Whenever the user takes part in any end-to-end encrypted communication, the system automatically generates dedicated public and private keys.

If this sounds too complicated, here is a very simple metaphor:

You just bought a new Rolex for your buddy, who lives in Australia. Now, it’s already in a fancy green leather box, so you decide to put the stamp directly on it and send it. There is nothing wrong with that approach as long as you trust that the postal workers won’t steal it.

However, if you decide to put the Rolex box inside another box, hiding the nature of the gift from all interacting parties along the way, then you’ve effectively ensured (for all intents and purposes) that the Rolex is only visible to the intended recipient; when your mate from down under gets a hold of the box, he takes his pair of scissors and ‘decrypts’ the present. Indeed, you’ve ensured ‘end-to-end’ encryption.

You’re already using end-to-end encryption, daily

As we mentioned before, during an E2EE interaction, the server that delivers encrypted data between one "end" and the other "end" is unable to decode and read the data it sends. Even the servers' owners are unable to access the information since it is not saved on the servers themselves, only the "endpoints" (or the devices) of the discussion can decode the data.

If you’re daily using messengers like WhatsApp, iMessage, and Signal (where E2EE is enabled by default) or Telegram, Allo, and Facebook's ‘Secret Conversation’ function (where E2EE can be manually activated) – you’re already using end-to-end encryption.

What's more fascinating is that E2EE communication providers don't require you to trust them. And that’s great!

The fact that their systems can be hacked makes no difference to you because the transported data is encrypted and can only be read by the sender and receiver, which has enraged several organizations. There are known cases when such agencies asked for special ‘backdoors’ that would allow them to decrypt messages.

Why isn’t everything end-to-end encrypted?

End-to-end encryption is theoretically sound, but it lacks flexibility, thus it can't be utilized when the "two ends" that communicate data don't exist, such as with cloud storage.

This is why Zero-Knowledge Encryption was created, a solution that overcomes the problem by hiding the encryption key, even from the storage provider, resulting in an authentication request without the requirement for password exchange.

Moreover, end-to-end encryption does not hide information about the message, such as the date and time it was sent or the people who participated in the conversation. This metadata might provide indications on where the 'end-point' might be – not great if you are the target of a hacker.

The biggest problem, however, is that in reality, we never know whether the communication is end-to-end encrypted. Providers may claim to provide end-to-end encryption when what they truly deliver is encryption-in-transit. The information might be kept on a third-party server that can be accessed by anybody who has access to the server.

Conclusion

While it’s obvious that you shouldn’t be shipping Dave’s Rolex in its fancy green box, the reality is, if you’ve nothing to hide and you’re not transporting something incredibly valuable, encryption-in-transit is up to the job.

End-to-end encryption is a wonderful technology that enables a high level of security when properly implemented. But it doesn't really tackle the main issue – the end-user, still, to this day, needs to trust the system that they’re using to communicate. We hope that the next generation of encryption technologies such as ZKP will be able to change that.

In this year of our lord, 2022, the term ‘Zero-Knowledge Encryption’ equates to best-in-class data insurance. We’ve already written an article named “What is Zero-Knowledge Proof?”, so we’re not going to look at definitions here, but rather, we’re going to explore the pros and cons of Zero-Knowledge proof encryption when compared to other technologies.

But for those who don’t want to dive deep into technical details, here’s an explanation of what Zero-Knowledge Encryption means:

It simply implies that no one else (not even the service provider) has access to your password-protected data.

This is important because even if your files are completely encrypted, if the server has access to the keys, a centralized hacker attack can result in a data breach.

In order to gain a better understanding of the factors that led to the development of Zero-Knowledge Encryption, we've decided to present a succinct, yet comprehensive, assessment of the advantages and disadvantages of three existing options:

Encryption-in-transit

Data in-transit, also known as data in motion, is data that is actively flowing from one point to another, such as that over the internet or over a private network. Data protection in transit refers to the security of data while it is being transferred from one network to another or from a local storage device to a cloud storage device. Effective data protection measures for in-transit data are critical because data is often considered less secure while in transit. Think of it like hiring security guards to accompany your cash-in-transit vehicle’s trip to the bank.

This means that, while using this approach, stored docs are 100% decryptable, so vulnerable.

As for our everyday life, the following technologies use the ‘encryption-in-transit’ approach:

• Transport Layer Security (TLS), which is aimed at ensuring your security on the web;
• Secure/Multipurpose Internet Mail Extensions (S/MIME), which are often used for email message security.

Encryption-at-rest

Any data encryption is the process of converting one type of data into another that cannot be decrypted by unauthorized users. For example, you may have saved a copy of your passport. You obviously don't want this data to be easily accessed. If you store encrypted data on your server, it’s effectively "resting" there (which is why it’s called encryption-at-rest). This is usually accomplished by the use of an algorithm that is incomprehensible to a user who does not have access to the encryption key needed to decode it. Only an authorized person will be able to access the file, ensuring that your data is kept safe.

The Advanced Encryption Standard (AES) is often used to encrypt data at rest.

But, in order to access the data, you need a key — and that’s where the potential vulnerability lies.

Encryption-at-rest is like storing your data in a secret vault, encryption-in-transit is like putting it in an armored vehicle with security guards for transport.

End-to-end Encryption

End-to-end encryption is the act of applying encryption to messages on one device so that only the device to which it is sent can decrypt it. The message travels all the way from the sender to the recipient in encrypted form.

In practice, it means that only the communicating users (who have the key) can read the messages.

End-to-end encryption has created an impregnable fortress for communication services (for example, messengers), going beyond the security "façade" of encryption-in-transit and encryption-at-rest solutions.

This is the most common approach when protecting oneself against data breaches nowadays, but it only works from "one end to the other," as the term implies. Even though this all sounds great, end-to-end encryption can only be used for a "communication system" like Whatsapp or Telegram.

While theoretically sound, end-to-end encryption lacks flexibility, so it can’t be used when the "two ends" that share data don't exist, such as for cloud storage.

This is the motivation behind the development of Zero-Knowledge Encryption, a method that solves the problem by hiding the encryption key, even from the storage provider, resulting in an authentication request without the need for password exchange.

Zero-Knowledge Encryption

To log in to an account, you usually have to type in the exact password. In today's hyperconnected world, it's normal practice to tell the server your secret key ahead of time and test whether it matches.

Instead, there is another, more secure way, to manage this delicate process and that’s called Zero-Knowledge Encryption.

Without diving deep, The Zero-Knowledge relies on three main requirements:

1. Completeness — an honest prover will be able to convince the verifier that he has the password by completing some process in the required way;
2. Soundness — the verifier will almost certainly discover when the prover is lying;
3. Zero-knowledge — if the prover has a password, the verifier receives no more information other than the fact that the statement is true.

Essentially, the system will check to see if you can demonstrate your knowledge several times by responding to various conditions. It’s like a brute force attack carried out backwards — you perform the same action many times in order to make sure that the prover isn’t lying.

Instead of concluding, let’s round up the pros and cons of Zero-Knowledge proof encryption when compared to the alternatives:

The con here is a clear example of the exceptional security provided by the Zero-Knowledge Encryption solution, which prevents even system administrators from recovering your password. This is why we, at Passwork, rely on this technology in our products. Ultimately, that’s why you can rely on us too.

Many times, we’ve mentioned self-signed certificates and their most common use cases in our blog. After all, the main difference between a regular certificate and a self-signed one is that in the latter case, you act as the CA (Certificate Authority). But there are a variety of services that provide CA services for free, with the most popular being ‘Let’s Encrypt’, which is going to be the subject of this article.

What’s that?

‘Let’s Encrypt’ is a free certificate authority developed by the Internet Security Research Group (ISRG).

It provides free TLS/SSL certificates to any suitable client via the ACME (Automatic Certificate Management Environment) protocol. You can use these certificates to encrypt communication between your web server and your users. ‘Let's Encrypt’ provides two types of certificates. Single-domain SSL and Wildcard SSL, which covers a single domain and all of its subdomains. Both types of SSL certificates have a 90-day validity period. These domain-validated certificates do not require a dedicated IP address. They accomplish this by delivering the client a unique token and then retrieving a key generated from that token via an HTTP or DNS request.

There are dozens of clients available which can be easily integrated with a variety of standard administrative tools, services, and servers. They also come written in a range of different computer languages.

We'll use the win-acme client in this tutorial because it's a basic, open-source, and constantly updated command-line application. It not only produces certificates but also automatically installs and renews them. And yes, this tutorial is for Windows users.

How does it work?

‘Let's Encrypt’ verifies the ownership of your domain before issuing a certificate. On your server, the Let's Encrypt client creates a temporary file (a token) with the required information. The Let's Encrypt validation server then sends an HTTP request to get the file and validates the token, ensuring that your domain's DNS record resolves to the ‘Let's Encrypt’ client-server.

In an HTTP-based challenge, for example, the client will generate a key from a unique token and an account token, then save the results in a file that the web server will serve. The file is then retrieved from the Let's Encrypt servers at: http://passwork.com/.well-known/acme-challenge/token.

The client has demonstrated that it can control resources on example.com if the key is correct, and the server will sign and provide a certificate.

How do I set it up?

Before we start:

• Make sure that you’ve downloaded the latest version of the application on the server from its Github release page;
• Scroll down to ‘assets’ and download the zip package named win-acme.v2.x.x.x.zip from the release page. If you're having difficulty with Internet Explorer, you may install Chrome on the server following this approach. Once the application has been downloaded, unpack it and save it somewhere safe for future use.

Now let’s Generate the Let’s Encrypt Certificates

Simply run wacs.exe to generate the Let's Encrypt certificates. Because we downloaded the application via the internet, you may receive a notification from Windows Defender claiming that "Windows protected your PC". Because of this, after clicking the "More Info" link, click the "Run Anyway" option. Because it’s open-source and widely utilized, the application is completely safe to use.

Follow these simple steps once the application has started:

• Choose N in the main menu to create a new certificate with default settings;
• Choose how you want to determine the domain name(s) that you want to include in the certificate. These may be derived from the bindings of an IIS site, or you can input them manually;
• A registration is created with the ACME server if no existing one can be found. You will be asked to agree to its terms of service and to provide an email address that the administrators can use to contact you;
• The program negotiates with the ACME server to try and prove your ownership of the domain(s) that you want to create the certificate for. By default, the http validation mode is picked and handled by our self-hosting plugin. Getting validation right is often the most tricky part of getting an ACME certificate. If there are problems, please check out some of the common issues for an answer;
• After the proof has been provided, the program gets the new certificate from the ACME server and updates or creates IIS bindings as required, according to the logic documented here;
• The program remembers all choices that you made while creating the certificate and applies them for each subsequent renewal.

For advanced instructions, visit this page.

And that’s pretty much it. It will successfully generate an SSL certificate for you if your domain is pointing to your server. It will also include a scheduled task that will renew the certificate when it expires. The SSL certificate will be installed automatically by the application.

Are there other options?

‘Certbot’ is the most widely used kind of ‘Let's Encrypt’ client. We didn’t give it much light in this article because it's “designed for Linux” and also a little more advanced. It comes with easy-to-use automatic configuration features for Apache and Nginx. And yes, there is a Windows version as well.

There are many other clients to choose from – the ACME protocol is open and well-documented. On their website, ‘Let's Encrypt’ keeps track of all ACME clients.

Here’s a list of the best options (n.b. most are for Linux):

• lego. Lego is a one-file binary installation written in Go that supports many DNS providers;
• acme.sh. Acme.sh is a simple shell script that can run in non-privileged mode and interact with more than 30 different DNS providers;
• Caddy. Caddy is a full web server written in Go with built-in support for Let’s Encrypt.

‘Let’s Encrypt’ is just great, there are no other ways to put it. It’s a free, automated, and open certificate authority, run for the public’s benefit. It can be accessed via a variety of tools and services. The best part is, they really keep their motto close to heart:

“We give people the digital certificates they need in order to enable HTTPS (SSL/TLS) for websites, for free, in the most user-friendly way we can. We do this because we want to create a more secure and privacy-respecting Web for all.”

It is rare for technologies to be born from ambitious philosophical concepts or mind games. But, when it comes to security and cryptography – everything is a riddle.

One of such riddles is ‘How can you prove that you know a secret without giving it away?’. Or in other words, ‘how can you tell someone you love them without saying that you love them?’.

The Zero-Knowledge Proof technique, as suggested by the name, uses cryptographic algorithms to allow several parties to verify the authenticity of a piece of information without having to share the material that makes it up. But how is it possible to prove something without supporting evidence? In this article, we’ll try our best to break it down for you as easily as possible.

Why?

We’re asking ourselves day after day – why on Earth would people decide to use such a complicated concept. Well, millions of people use the internet every day, accepting cookies and sharing personal information in exchange for access to services and digital products. Users are gradually becoming more vulnerable to security breaches and unauthorized access to their data. Furthermore, individuals frequently have to give up their privacy in return for digital platform services such as suggestions, consultations, tailored support, and so on, all of which wouldn’t be available when browsing privately. Due to all the above mentioned, there is a certain asymmetry regarding access to information – you give your information in exchange for a service.

In 1985, three great minds noticed ‘a great disturbance in the Force’ ahead of their time and released a paper called "The Knowledge Complexity of Interactive Proof-Systems" which introduced the concept of Zero-Knowledge Proof (ZKP) for the first time.

So what is it?

ZKP is a set of tools that allows an item of data to be evaluated without having to reveal the data that supports it. This is made feasible by a set of cryptographic methods that allow a "tester" to mathematically prove to a "verifier" that a computational statement is valid without disclosing any data.

It is possible to establish that particular facts are correct without having to share them with a third party in this way. For example, a user could demonstrate that he is of legal age to access a product or service without having to reveal his exact age. Or, it’s a bit like showing your friend your driving license instead of proving to him that you can drive by road-tripping to Mexico.

This technique is often used in the digital world to authenticate systems without the risk of information being stolen. Indeed, it’s no longer necessary to provide any personal data in order to establish a person's identity.

Sounds great, but how does it work?

The prover and the verifier are the two most important roles in zero-knowledge proofs. The prover must demonstrate that they are aware of the secret whereas the verifier must be able to determine whether or not the prover is lying.

It works because the verifier asks the prover to do actions that can only be done if the prover is certain that he or she is aware of the secret. If the prover is guessing, the verifier's tests will catch him or her out. If the secret is known, the prover will pass the verifier's exam with flying colours every time. It's similar to when a bank or other institution requests letters from a known secret word in order to authenticate your identity. You're not telling the bank how much money you have in your account; you're simply demonstrating that you know.

Wonderful, but how does it REALLY work?

To answer this, let’s take a look at a piece of research by Kamil Kulesza.

Assume that two characters, Alice and Bob, find themselves at the mouth of a cave with two independent entrances leading to two different paths (A and B). A door inside the cave connects both paths, but it can only be unlocked with a secret code. This code belongs to Bob (the 'tester,') and Alice (the 'verifier,') wants to buy it, but first, she wants to make sure Bob isn't lying.

How can Bob demonstrate to Alice that he has the code without divulging its contents? They perform the following to achieve this: Bob enters the cave via one of the entrances at random while Alice waits outside (A or B). Once inside, Alice approaches the front door, summons Bob, and instructs him to use one of the two exits. Bob will always be able to return by the path that Alice used since he knows the secret code.

Bob will always be able to return via the path that Alice directs him to, even if it does not coincide with the one he chose in the first place, because he can unlock the door and depart through the other side with the secret code.

But wait a minute, there is still a 50% chance that both Alice and Bob chose the same path, right? It is correct indeed, however, if this exercise is repeated several times, the likelihood that Bob will escape along the same path chosen by Alice without possessing the code decreases until it is almost impossible. Conclusion? If Bob leaves this path a sufficient number of times, he has unmistakably shown to Alice that his claim of holding the secret code is true. Moreover, there was no need to reveal the actual code in this case.

You can find out more about the Bob and Alice metaphor here.

Got it, so how is it used?

As for right now, ZKP is developing hand in hand with blockchain technology.

Zcash is a crypto platform that uses a unique iteration of zero-knowledge proofs (called zk-SNARKs). It allows native transactions to stay entirely encrypted while still being confirmed under the network's consensus rules. It’s a great example of this technology being used in practice.

Even though zero-knowledge proofs have a lot of potential to change the way today's data systems verify information, the technology is still considered to be in its infancy — primarily because researchers are still figuring out how to best use this concept while identifying any potential flaws. This, however, doesn’t stop us from using this protocol in our products! ;)

For a deeper understanding of the technical aspects and history behind this protocol, we recommend watching this video on YouTube.

The Secure Sockets Layer (SSL) and the Transport Layer Security (TLS) cryptographic protocols have seen their share of flaws, like every other technology. In this article, we would like to list the most commonly-known vulnerabilities of these protocols. Most of them affect the outdated versions of these protocols (TLS 1.2 and below), although one major vulnerability was found that affects TLS 1.3.

POODLE

This cute name should not misguide you – it stands for Padding Oracle On Downgraded Legacy Encryption. Not that nice after all, right? It was published in October 2014 and it takes advantage of two peculiar facts. The first one is that some servers/clients still support SSL 3.0 for interoperability and compatibility with legacy systems. The second one is a vulnerability related to block padding that appears in SSL 3.0. Here is a link to that vulnerability on the NIST NVD database.

How does it work?

As mentioned before, this vulnerability comes from the Cipher Block Chaining (CBC) mode. Those block ciphers use blocks of a fixed length, so if the data in the last block is shorter than the block’s size, it is filled by padding. The server, of course, ignores such padding by default, it only checks whether the length is correct and verifies the Message Authentication Code (MAC) of the plaintext. In practice, this means that the server cannot verify if the content inside the padding has been altered in any way.

An attacker is able to modify padding data and then simply waits for the server’s response. Attackers can recover the contents byte-by-byte by watching server responses and altering the input. It usually takes no more than 256 attempts to reveal one byte of a cookie, which equates to a maximum of 4096 queries for a 16-bit cookie. Just by using automated scripts, the hacker may retrieve the plaintext char by char. Such a plaintext may be anything from a password to a cookie or a session. So, without even knowing the encryption method or key, a sniffer may easily decipher a block.

BEAST

The Browser Exploit Against SSL/TLS attacks was disclosed in September 2011. It affects browsers that support TLS 1.0, because this early version of the protocol has a vulnerability when it comes to the implementation of the above-mentioned CBC mode. Here’s a link to it in the NIST NVD database.

How does it work?

This kind of attack is usually client-side, so in order for it to succeed, an attacker should, in one way or another, have some control of the clients’ browser. After getting access to a browser, the attacker would typically use MITM to inject packets into the TLS stream. After such an injection, the only thing left is to guess the Initialization Vector (IV) – a random block of data that makes each message unique. This is used with the injected message and then simply compared with the results of the needed block.

CRIME

The Compression Ratio Info-leak Made Easy (CRIME) vulnerability affects TLS compression. The Client Hello message optionally uses the DEFLATE compression method, which was introduced to SSL/TLS to reduce bandwidth. The main method used by any compression algorithm is to replace repeated byte patterns with a pointer to the first instance of such sequences. As a result – the bigger the repeated sequences, the more effective such a compression is. You can visit this link to locate this vulnerability in the NIST NVD database.

How does it work?

Let’s imagine that a hacker is targeting cookies. He knows that the targeted website creates a cookie for each session named ‘ss’. The DEFLATE compression method replaces repeated bytes and our antagonist knows that. Therefore, he injects Cookie:adn=0 to the victim’s cookie. The server would, of course, append 0 to the compressed response, because Cookie:adn= has been already sent, so it is repeated.

After that, the only thing for an attacker to do is to inject different characters and then monitor the size of the response.

The injected character is contained in the cookie value if the answer is shorter than the first one, hence the compression. The response will be longer if the character is not in the cookie value. Using this strategy, an attacker can recreate the cookie value using the server's feedback.

By the way, the BREACH attack is very similar to CRIME, but it targets HTTP compression instead.

Heartbleed

Heartbleed was a major vulnerability discovered in the OpenSSL (1.0.1) library's heartbeat extension. This extension is used to maintain a connection so long as both participants are online. Here is its link on our beloved NIST NVD database.

How does it work?

The client sends the server a heartbeat message with a payload containing data and its size + padding. The server will respond with the same heartbeat request as the client.

The vulnerability comes from the fact that if the client sent a false data length, the server would respond with a heartbeat response containing not only the data received by the client but, because it needs to fill the length of the message, also with random data from its memory. A very unfortunate technical solution, isn’t it?

Leaking such unencrypted data may result in a disaster. It is well-documented that by using such a technique, an intruder may obtain a private key to the server. Moreover, if the attacker has the private key – well, that means he’s able to decrypt all the traffic to the server. I guess we don’t need to tell you why that’s no good, right?

The entire list of vulnerabilities may be found in this wonderful report by the Health Sector Cybercecurity Coordination Center. It not only lists all above-mentioned techniques in a very informative manner but also provides a very neat table of all ‘Known Threats to TLS/SLS’ (pp. 24-26).

Instead of a long conclusion, let’s just look at the last page of that report:

The green cell of the chart explicitly states how to get rid of most known vulnerabilities. Indeed, if you’re not interested in trawling through the nooks and crannies of the Library of Alexandria’s floor on Cybersecurity, the best way to track existing SSL/TLS vulnerabilities is by visiting csrc.nist.gov once in a while. You might even consider making it your homepage.

Security, security, security… There is no way one can underestimate the importance of it when it comes to caring for private files and sensitive data. As long as the world of cybersecurity is privy to the constant conflict between hackers and programmers, fully protecting yourself and your business will forever be impossible. But, as we know, hackers aren’t always using state-of-the-art techniques. Often, they’re still getting in by guessing your username and password.

Most popular kinds of technology are under a constant barrage of hacking attempts, which is why it is so important to follow simple protocols to save yourself both time and money. One of such technologies is SSL/TLS. It is used on almost every web service, and even though it may seem straightforward to set up, there are many arcane configurations and design choices that need to be made to get it ‘just right’.

This guide will provide you with a short ‘checklist’ to keep in mind when setting up or maintaining SSL/TLS with a focus on security. All information is accurate and up to date as of December 2021 and is based on both our experience and other guides made on this topic.

Track all your certificates

First and foremost, you should check up on all existing certificates that are used by you and your organisation. This covers all information about them, such as their owners, locations, expiration dates, domains, cipher suites, and TLS versions.

If you don’t know about, or don’t track existing certificates as well as weak keys and cipher suites, you expose yourself to security breaches connected to expiring certificates.

An easy way to list all your certificates is to get them from your CA. This may not work if you used self-signed certificates, which require additional attention in terms of tracking/listing. The second way, which is typically quite effective, is to obtain certificates using network scanners. Hopefully, the enormous number of certifications that you were unaware of will not surprise you. Your certificate ‘inventory’ should focus on details such as OS and applications like Apache, just because your organization could be vulnerable to exploits that attack specific versions of things like OpenSSL (i.e., Heartbleed).

So, your list of certificates should include:

1. Certificates issued
   • Certificate types
   • Key sizes
   • Algorithms
   • Expiration dates
2. Certificate locations
3. Certificate owners
4. Web server configurations
   • O/S versions
   • Application versions
   • TLS versions
   • Cipher suites

Don’t use weak keys, cipher suites or hashes

Every certificate has a public key and a signature, both of which may be vulnerable if they were created with outdated technology. On public web servers, certificates with key lengths of less than 2048 bit or those that employ older hashing algorithms like MD5 or SHA-1 are no longer allowed. These may, however, be found on your internal services. If that's the case, you'll need to upgrade them.

The requirement to check TLS/SSL versions and cipher suites supported on your web servers is much more crucial than finding certificates with weak keys or hashes.

The following versions are outdated and must never be used:
• SSL v2
• SSL v3
• TLS 1.0
• TLS 1.1
Instead, enable TLS 1.2 and TLS 1.3.

The following cipher suites are vulnerable, and must be disabled:
• DES
• 3DES
• RC4
Instead, use modern ciphers like AES.

Install and renew all certificates on time

We recommend renewing a certificate at least 15 days before it expires to allow time for testing and reverting to the prior certificate if any problems arise.

Users should be notified when certificates expire, regardless of the mechanism you employ. Before expiration, the system should alert users automatically and at regular intervals (e.g., 90 days). Self-signed certificates should never have an expiration date of more than 30 days.

Never reuse key pairs for new certificates

By the same token, never reuse CSRs (Certificate Signing Requests) — this will automatically reuse the private key. Reusing keys leads to key pair vulnerability. Don’t be lazy when it comes to your security.

Review the CA that you use

Your certificates are only as trustworthy as the CA that issues them. All publicly trusted CAs are subject to rigorous third-party audits to maintain their position in major operating system and browser root certificate programs, but some are better at maintaining that status than others.

Use Forward Secrecy (FS)

Also known as perfect forward secrecy (PFS), FS assures that a compromised private key will not also compromise past session keys. To enable it, use at least TLS 1.2 and configure it to use the Elliptic Curve Diffie-Hellman (EDCHE) key exchange algorithm. The best practice here would be to use TLS 1.3 as it provides forward secrecy for all TLS sessions using the Ephemeral Diffie-Hellman key exchange protocol ‘out of the box’.

Use DNS CAA

DNS CAA is a standard that allows domain name owners to restrict which CAs can issue certificates for their domains. In September 2017, the CA/Browser Forum mandated CAA support as part of its certificate issuance standard baseline requirements. The surface area prone to attack is certainly shrunk with CAA in place, effectively making sites more secure. If CAs have an automated mechanism in place for certificate issuance, they should check for DNS CAA records to prevent certificates from being issued incorrectly. It is advised that you add a CAA record to your certificate to whitelist a CA. Add certificate authorities (CAs) that you trust.

Keep in mind that encryption is not an option.

Enforce encryption across your entire infrastructure — no 'bald spots' should remain. Leaving elements of your infrastructure unprotected is like forgetting to lock the door when you leave — it's not a good idea.

The practices that we’ve mentioned in this list are more about common sense, rather than knowledge acquired through the ultra-secret bureau. When it comes to security, you should always keep your infrastructure up-to-date. New vulnerabilities pop up every day, but still, we, humans, pose the biggest threat of all. In other words, human error has more to answer for than we might first believe. Because of this, double-check everything you do. Security protocols should be easy to follow not only by the person who creates them but also by everyone who interacts with your infrastructure — users and employees alike.

With such a checklist, it’s impossible to shine a light on each and every nook and cranny, so for those of you who want to ensure that you’re following all best practices, consider checking out this list.

Most web servers across the internet and intranets alike use SSL certificates to secure connections. These certificates are traditionally generated by OpenSSL – a software library containing an open-source implementation of the SSL and TLS protocols. Basically, we’re looking at a core library, providing us with a variety of cryptographic and utility functions. Because of its ease-of-use and, most importantly, because it’s open-source (so, free), it managed to make its way to the top, and now, it’s the industry standard.

OpenSSL is available for Windows, Linux and MacOS. So, before you get started, make sure that you have OpenSSL installed on your machine. Here’s a list of precompiled binaries for your convenience. But, to be honest, the OS doesn’t really matter here too much – the commands are going to be identical in our case.

In this tutorial, we’ll show you how easy it can be to generate self-signed certificates with OpenSSL.

Such a self-signed certificate is great if you want to use HTTPS (HTTP over TLS) to secure your Apache HTTP or Nginx web server, and you know that your certificate doesn’t need to be signed by a CA.

How should I use OpenSSL?

OpenSSL is all about its command lines. Below, we’ve put together a few common OpenSSL commands that regular users can fiddle about with to generate private keys. After each command, we’ll try to explain what that exact line of code does by breaking it down into its constituent parts. If you fancy studying all of the commands, take a look at this page.

How can I generate self-signed certificates?

Let’s start! First and foremost, we want to check whether we have OpenSSL installed. To do that, we need to run:

openssl version -a

If you get something like this, you’re on the correct path:

OpenSSL 3.0.0 7 sep 2021 (Library: OpenSSL 3.0.0 7 sep 2021)
built on: Tue Sep  7 11:46:32 2021 UTC
platform: darwin64-x86_64-cc
options:  bn(64,64)
compiler: clang -fPIC -arch x86_64 -O3 -Wall -DL_ENDIAN -DOPENSSL_PIC -D_REENTRANT -DOPENSSL_BUILDING_OPENSSL -DNDEBUG
OPENSSLDIR: "/usr/local/etc/openssl@3"
ENGINESDIR: "/usr/local/Cellar/openssl@3/3.0.0_1/lib/engines-3"
MODULESDIR: "/usr/local/Cellar/openssl@3/3.0.0_1/lib/ossl-modules"
Seeding source: os-specific
CPUINFO: OPENSSL_ia32cap=0x7ffaf3bfffebffff:0x40000000029c67af

This code effectively specifies the SSL version that you have installed and some other details.

Now, the first important thing on our agenda is to generate a Public/Private keypair. To do this, we ought to punch in the following command:

openssl genrsa - out passwork.key 2048

genrsa – is the command to generate a keypair with the RSA algorithm;

-out passwork.key – this is the output key file name;

2048– key size. Make sure to double-check your requirements at this stage, because that value may change depending on your use case.

Now we have the file ‘passwork.key’ in a directory that we’ve specified. Once we’ve created a file we can, for example, extract the public key by running:

openssl rsa -in passwork.key -pubout -out passwork_public.key

rsa – we ought to specify the algorithm that we used;

-in passwork.key – we take the existing keypair;

-pubout – here, we take only public key;

-out passwork_public.key – we’re exporting this as a file with name passwork_public.key.

Now we may proceed to creating a CSR – Certificate Signing Request. In a real production scenario, such a CSR is forwarded to the CA which signs it on your behalf, so you get a certificate. But for the sake of our tutorial, we’ll create a CSR and self-sign it.

The command to create a CSR is as follows:

openssl req -new -key passwork.key -out passwork.csr

req -new – here, we’re specifying that we want to create something new;

-key passwork.key – here, we’re specifying the key that we will use;

-out passwork.csr – here, we’re specifying the output file.

After pressing ‘Enter’ you’ll see something like this:

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields, there will be a default value,
If you enter '.', the field will be left blank.

Enter the required data. For the purposes of our tutorial, we’ve entered the following fake values:

-----
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:FL
Locality Name (eg, city) []:Tallahassee
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Passwork
Organizational Unit Name (eg, section) []:.
Common Name (e.g. server FQDN or YOUR name) []:*.passwork.com
Email Address []:[email protected]
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

One of the most important fields is Common Name, which should match the server name or FQDN where the certificate is going to be used.

After all the above-mentioned steps, we’ll have our CSR file fully generated. In the real world, at this stage, we’d want to verify our CSR file, just so we’re not passing the wrong file to the CA. Also, it’s good practise to double-check whether the FQDN is correct.

Having all that in mind, we run:

openssl req -text -in passwork.csr -noout -verify

The output, in our case, would be:

Certificate request self-signature verify OK
Certificate Request:

As you can see, it lists crucial data that you provided when you answered questions related to the CSR. Check the values and if something is wrong – simply re-generate the CSR before you pass it on to the CA.

As we mentioned before, instead of passing our CSR to the CA, we’ll create a self-signed certificate. In order to do that, we ought to enter the following:

openssl x509 -in passwork.csr -out passwork.crt -req -signkey passwork.key -days 30

The  ‘X509’ command is our multi purpose certificate utility;

-in passwork.csr represents our CSR;

-out passwork.crt is the name and file extension for our certificate;

-req signkey passwork.key – here, we’re specifying the keypair that we want to use to sign our certificate;

-days 30 – this is an expiration time interval for our certificate.

The passwork.crt certificate file has now been generated, so it’s ready to go! Pretty easy, right? Well, it gets a lot easier when we remember that we can generate a self-signed certificate by just entering:

openssl req \
-newkey rsa:2048 -nodes -keyout passwork.key \
x509 -days 365 -out domain.crt

Here, a temporary CSR is generated, so we don’t have to enter all the data manually.

Please bear in mind that in real-life situations, you should follow best practice when creating a private key, they can be easily generated and therefore compromised.

Conclusion

We’ve barely touched the functionalities within OpenSSL, but as you can see, it’s not as complicated as many people first think – that’s why it’s loved far and wide. If you’ve still got any unanswered and burning questions, feel free to check out the frequently-asked questions (FAQ) page on the OpenSSL project’s website. If that’s not enough and you’re really looking for a deep dive – we can’t recommend this free e-book highly enough.

The SSL/TLS protocol’s job is to ensure security through authentication. It was designed to encrypt data transmitted over open networks and, as a result, protect against interception and spoofing attacks. TLS also authenticates communicating parties, which leaves us with a pretty trusting environment. It goes without saying that security through authentication is essential for a successful business in the 21st century.

If we closely observe the way in which SSL works, it becomes very clear very fast, that to establish the ‘trusting environment’, SSL certificates need to be signed and validated by a trusted Certificate Authority (CA). Now, while everyone trusts the CA, by extension, they are able to trust those with its certification. Traditionally, organizations have used CAs to sign their SSL/TLS certificates, but with an influx of digital products, a huge amount of software being developed and tested in addition to an all-time data breach record, many companies are switching to self-signed certificates.

What is a Self-Signed SSL Certificate?

A self-signed certificate is a digital certificate that hasn’t been signed by a publicly trusted CA. Instead, it is issued and signed by the entity that is responsible for the software. This, on the one hand, makes deployment pretty frictionless, but on the other, it comes with additional risk, especially when poorly implemented.

Although they can be risky, self-signed certificates are incredibly widespread. These certificates are available with no associated costs and can be requested easily by anyone, which is fantastic for internal testing environments or web servers that are otherwise locked for external users. Moreover, such a certificate still uses the same encryption methods as other, paid SSL/TLS certificates – that’s a piece of very good news for organizations because nobody wants their data leaking. As long as the CA doesn’t require a certificate expiry date, a self-signed certificate may be issued once and used till the end of time. This is used, for example, when working on some secret projects or simply with internal data.

For many companies that use self-signed certificates, the biggest advantage is, of course, independence. All security infrastructure is encapsulated inside the internal network, so even if such a network isn’t connected to the web at all – it’ll still work as intended.

Although this looks very convenient on the surface, it is one of the major concerns when dealing with these types of certificates. Offline, they aren’t able to receive security updates in response to discovered vulnerabilities, nor meet the certificate agility which is essential to secure today's modern enterprise.

Another challenge that arises when dealing with self-signed certificates is that responsible departments often lack visibility over how many were issued, where they are used, by whom, and also how the private key is stored. It’s hard enough to keep track of certificates issued by different public and private CAs. It’s almost impossible to track all self-signed certificates without an additional request process.

Pros:

• Fast and easy to issue;
• Useful in test environments;
• Flexibility;
• Independence;
• No expiration date.

Cons:

• No security updates;
• Can’t be easily revoked;
• Lack of visibility and control.

Let’s imagine that our internal network has been breached. If we use self-signed certificates, there is literally no way of knowing if it, and private keys associated with it, have been compromised. Once compromised, such a certificate may be used to spoof identities and gain access to important data, especially considering the fact that, unlike CA-issued certificates, self-signed certificates cannot be revoked and, as we mentioned before, have no expiration date. You cannot simply ‘revoke’ a private key in such a situation.

So, why are self-signed certificates still in use? The simple answer is that it’s convenient. The routine manual process of submitting a certificate signing request (CSR) and waiting hours for verification is just horrible. To save time and frustration, it makes more sense to opt for self-signed certificates.

So the biggest question on self-signed certificates of any type is not how to issue them, but how to properly implement them inside an organisation. It’s like making sushi – the recipe is very simple, but the devil is in the details.

Some risks may be indirect – let’s imagine we’re looking to use a self-signed certificate to provide access to an employee portal. It will cause any default browser to alert the user with warnings. As these alerts can be ignored, many organisations tend to instruct their employees to do exactly that – ignore warnings. The safety of the internal portal is assured, so there is no direct harm, but, at the same time, employees ‘learn’ to ignore alerts and warnings the same way we all ignore ads on websites. Such practices make the organisation overall more vulnerable. The crux of the matter is that employees just don’t provide essential feedback on time if something goes very wrong.

To get the best out of self-issued certificates and mitigate the risks involved, we recommend using OpenSSL to issue certificates. It is de facto an industry standard. But, as mentioned before, this is not enough. Correct implementation is even more important than the tools used. After all, a top of the line DeWalt grinder is going to be useless if you’re using it to hammer in a nail. So, when implementing a self-signed certificate try to follow these best practices:

• Limit the expiration period, it should be as short as possible. Never use certificates that don’t feature an expiry date.
• Limit usage. Never create ‘universal certificates’ that open all doors at once.
• Use a meaningful and informative ‘subject’ record. Everybody should understand what the certificate is being used for.
• Make sure that the algorithm used for the signature is at least SHA256WITHRSA (which is the default in OpenSSL).
• Create only encrypted private keys.
• Use elliptic curve keys as opposed to the default RSA ones; they provide a number of benefits over RSA.
• Most importantly, create a repeatable/scriptable process for issuing certificates and keys. OpenSSL is a de-facto standard command-line tool that can be used as the basis for this process.

Self-signed certificates are fast and easy to use, they are great for test environments, or when providing encrypted access to internal data. They provide independence and are free to use. That is why they are used across the board in so many companies. On the whole, there’s really no other way to do things right. But remember, SSL/TLS self-signed certificates are like fugu fish – it is delicious when cooked well, but you’ll drop dead if the chef’s on his lunch break.

Stuck between a proxy and a hard place

Let’s imagine that you’re managing a small team, all of whom are coming back to work after a relaxing furlough period. Of course, you’re going to notice a drop in productivity; your team has become accustomed to browsing YouTube between Zoom calls and messaging their friends on Facebook. The solution? A ‘forward proxy’, which is the kind of proxy you’re likely to be familiar with. This will make sure that employees are prompted to get the ‘Pass’ back to work, should they try to access social networking.

Now, perhaps you have an update scheduled for your website, but you’re still not sure whether you’ve caught all the bugs. Or, maybe you want to scale your infrastructure in a ‘plug'n'play’ way. How are you going to test out new features on a certain percentile of your users? Here, you’ll find faithful solace in the almighty powers of the ‘reverse proxy’.

Whether you’re looking to learn more about forward or reverse proxies, today we’ll take a deep dive and explore how you can level up your business’ IT infrastructure through their use.

So, what’s a proxy server?

A proxy server is effectively a gateway between networks or protocols. They usually separate the end-user from the server. They also can alter or redirect the connection or data that passes through. Moreover, proxies come in a variety of 'tastes and colours' depending on their use case, the system complexity, privacy requirements, and so on.

If you’re using a proxy server, any data you send to the external network ought to flow through it beforehand. Also, it works both ways, so you, the client, cannot be reached by someone on the external net without that data first being sent through the proxy.

Importantly, there are two main types of proxies: Forward Proxies and Reverse Proxies. And even though the principle behind these two is similar, their use cases differ greatly.

Forward Proxies

In your day-to-day life, you’ll encounter forward proxies the most – these kinds of proxies sit between the client and the external network. They evaluate outbound requests and take action on them before relaying those requests to the external resources. Forward proxy servers allow the redirecting of traffic, meaning that if you have a proxy server installed within your local enterprise or on your home network, you’re able to effectively block choice websites. Maybe you don't want your kids to watch Netflix, or Dave from accounting keeps stalking his ex on Facebook when he should be writing up a report – in both cases, installing a proxy is a great solution. VPNs have a very similar function but feature encrypted traffic flows, if you’re on the market for such a tool, we recommend ExpressVPN. We’d also recommend steering clear of free proxies as there have been notable instances of traffic logging and sale on the black market.

Now, when using proxies, servers outside your network can’t understand who the client is, so by the same token, individuals or companies using forward proxies may access material that would otherwise be banned in their country or office. That’s exactly how the ‘GreatFirewall of China’ works, and it’s also how you’re able to stream a season on Netflix that would otherwise be banned in your country. This is why your office should restrict software downloads and access to in-browser forward proxies. Otherwise, Dave is just going to fight fire with fire.

So generally speaking, forward proxies are used to filter or unfilter Web content (depending on which side of the fence you sit).

Reverse proxies

Now that we’ve explained how a forward proxy works, disguising the client’s identity from the server, you can probably guess that the reverse proxy works vice-versa; the client doesn't know what exact server it is contacting. That may be used, for example, to help you rebalance the bandwidth between your service’s servers. That way, you can connect users to servers with the lowest load, or the smallest ping. Or, if your servers have a lot of static data - such as js scripts or HTML files on your website, they can be cached on a proxy server. Big social networks use reverse proxies to distribute the traffic among users' locations and corresponding data centers. The end-user, in most cases, remains oblivious to your internal process.

Some popular open-source reverse proxies are:

• Varnish
• Squid

Still, most webmasters use the NGINX Reverse Proxy as it allows you to easily pass any request to a proxied server, configure buffers and choose the outgoing IP address.

The benefits of using a reverse proxy for your backend infrastructure are very straightforward:

• Load balancing – you’re able to set up your proxy server to choose the least loaded server each time a client makes a call. This will, of course, make the end-user experience incredibly smooth.
• Caching – as mentioned before, if your users perform identical calls to your server, you can store some data on the proxy server instead of loading your servers with heaps of requests (however, don't forget that caching on a proxy can sometimes be dangerous, so approach with caution).
• Isolating internal traffic – one of the best features indeed! You can run all your internal server architecture within a completely isolated DMZ. Also, it would remain a secret. All your port preferences, containers, virtual servers and physical servers shan’t be exposed to the outer world. This, of course, adds another layer of security to your infrastructure.
• Logging – you can log all internal network events on your reverse proxy. This means that if one of your servers returns an error – you can query and debug it on your proxy server. Moreover, it allows you to monitor the overall performance of your infrastructure easily from a single node.
• Canary Deployment – this means you can test some new features on only a selected percentage of users, You can also perform other AB tests. All of this allows you to significantly reduce risks when deploying updates to your service – your API calls are the same, the ports are the same, but your content is able to change dramatically.
• Scalability – if you need more servers, set them up and add them to the list of proxied servers. That's as simple as it gets.

There are plenty of scenarios and use cases in which having a reverse proxy can make all the difference when looking to improve the speed and security of your corporate network. By providing you with a point at which you can inspect traffic and route it to the appropriate server, or even one where you may transform the request entirely, a reverse proxy can be used to achieve a variety of different goals.

Using forward and reverse proxies allows you to significantly simplify your internal infrastructure. Not only are you bound to increase efficiency by keeping Dave off of Facebook, but you’re also adding another layer of security for both your employees and your servers. Logging will allow you to track your network usage and debug certain issues. In addition, caching definitely offers a smoother and more consistent experience to your end-users. So, throw your doubts to the wind and get involved. After all, most of the other successful services do it too.

Cryptography is both beautiful and terrifying. Perhaps a bit like your ex-wife. Despite this, it represents a vital component of day-to-day internet security; without it, our secrets kept in the digital world would be exposed to everyone, even your employer. I doubt you’d want information regarding your sexual preferences to be displayed to the regional sales manager while at an interview with Goldman Sachs, right?

Computers are designed to do exactly what we ask them to do. But sometimes there are certain things that we don’t want them to do, like expose your data through some kind of backdoor. This is where cryptography comes into play. It transforms useful data into something that can’t be understood without the proper credentials.

Let’s take a look at an example. Most internet services need to store their users’ password data on their own servers. But they can’t store the exact values that people input on their devices because, in the event of a data breach, malevolent intruders would effectively gain access to a simple spreadsheet of all usernames and passwords.

This is where ‘Hash’ and ‘Salt’ help us a lot. Throughout this article, we’re going to explain these two important encryption concepts through simple functions in Node.JS.

What is a ‘hash’?

A ‘hash’ literally means something that has been chopped and mixed, and originally was used to describe a kind of food. Now, chopping and mixing are exactly what the hash function does! You start with some data, you pass it through a hash function where it gets whisked and chopped, and then you watch it get transformed into a fixed-length value (which at first sight seems pretty meaningless). The important nuance here is that, contrary to cooking, an input always produces a corresponding output. For the purposes of cryptography, such a hash function should be easily computable and all values should be unique. It should work in a similar way to mashing potatoes – mashing is a one-way process; the raw potato may not be restored once it has been mashed. Indeed, the result of a hash function should be impenetrable to computer-led reverse engineering efforts.

These properties come in handy when you’re looking to store user passwords on a database – you don’t want anyone to know their real values.

Let’s implement a hash in Node.JS!

First, let’s import the createHash function from the built-in ‘crypto’ module:

const { createHash } = require ('crypto');

Next, we ought to define the module that we’re naming as the ‘hash’ (which takes a string as the input, and returns a hash as the output):

function hash(input) {
    return createHash();
}

We also need to specify the hashing algorithm that we want to use. In our case, it will be SHA256. SHA stands for Secure Hash Algorithm and it returns a 256-bit digest (output). It is important to architect your code so it is easy to switch between algorithms because at some point in time they won’t be secure anymore. Remember, cryptography is always evolving.

function hash(input) {
    return createHash('sha256');
}

Once we call our hashing function, we may call ‘update’ with the input value and return the output by calling ‘digest’. We should also specify the format of the output (e.g. hex). In our case, we’ll go with Base64.

function hash(input) {
    return createHash('sha256').update(input).digest('base64');
}

Now that we have our hash function, we can provide some input, and console log the result.

let youShallNotPassPass = 'admin1234';
const hashRes1 = hash(youShallNotPassPass);
console.log(hashRes1)

Here’s our baby hash:
rJaJ4ickJwheNbnT4+I+2IyzQ0gotDuG/AWWytTG4nA=

So, how can we use this long, convoluted string of numbers, letters, and symbols? Well, now it’s easy to compare two values while operating with only hashes.

let youShallNotPassPass = 'admin1234';
const hashRes1 = hash(youShallNotPassPass);
const hashRes2 = hash(youShallNotPassPass);
const isThereMatch = hashRes1 === hashRes2;
console.log(isThereMatch ? 'hashes match' : 'hashes do not match’)

As long as hash values are unique object representations, they can be useful for object identification. For example, they might be used to iterate through objects in an array or find a specific one in the database.

But we have a problem. Hash functions are very predictable. On top of that, people don’t use strong passwords that often, so the hacker may just compare the hashes on a database with a precomputed spreadsheet of the most common passwords. If the values match –  the password is compromised.

Because of this, it’s insufficient to just use a hash function to store unique ids on a password database.

And that’s where our second topic makes an entrance – Salt.

‘Salt’ is a bit like the mineral salt that you would add to a batch of mashed potatoes – the taste will definitely depend on the amount and type of salt used. This is exactly what salt in cryptography is – random data that is used as an additional input to a hash function. Its use makes it much harder to guess what exact data stands behind a certain hash.

So, let’s salt our hash function!

First, we ought to import ‘Scrypt' and ‘RandomBytes’ from the ‘crypto’ module:

const { scryptSync, randomBytes } = require('crypto');

Next, let’s implement signup and login functions that take ‘nickname’ and ‘password’ as their inputs:

function signup(nickname, password) { }
function login(nickname, password) { }

When the user signs up, we will generate a salt, which is a random Base64 string:

const salt = randomBytes(16).toString('base64');

And now, we hash the password with a 'pinch' of salt and a key length, which is usually 64:

const hashedPassword = scryptSync(password, salt, 64).toString('base64');

We use ‘Scrypt’ because it’s designed to be expensive computationally and memory-wise in order to make brute-force attacks unrewarding. It’s also used as proof of work in cryptocurrency mining.

Now that we have hashed the password, we need to store the accompanying salt in our database. We can do this by appending it to the hashed password with a semicolon as a separator:

const user = { nickname, password: salt + ':' + hashedPassword}

Here’s our final signup function:

function signup(nickname, password) {
    const salt = randomBytes(16).toString('base64');
    const hashedPassword = scryptSync(password, salt, 64).toString('base64');
    const user = { nickname, password: salt + ':' + hashedPassword};
    users.push(user);
    return user;
}

Now let’s create our login function. When the user wants to log in, we can grab the salt from our database to recreate the original hash:

const user = users.find(v => v.nickname === nickname);
const [salt, key] = user.password.split(':');
const hash = scryptSync(password, salt, 64);

After that, we simply check whether the result matches the hash in our database. If it does, the login is successful:

const match = hash === key;
return match;

Here is the complete login function:

function login(nickname, password) {
    const user = users.find(v => v.nickname === nickname);
    const [salt, key] = user.password.split(':');
    const hash = scryptSync(password, salt, 64).toString('base64');
    const match = hash === key;
    return match;
}

Let’s do some testing:

//We register the user:
const user = signup('Amy', '1234');

//We try to login with the wrong pass:
let isSuccess = login('Amy', '12345');
console.log(isSuccess ? 'Login success' : 'Wrong password!')

//Wrong password!
//We try to login with the correct pass:
isSuccess = login('Amy', '1234')
console.log(isSuccess ? 'Login success' : 'Wrong password!')

//Login success

Our example, hopefully, has provided you with a very simplified explanation of the signup and login process. It’s important to note that our code is not protected against timing attacks and it doesn’t use PKI infrastructure to check hashes, so there are plenty of vulnerabilities for hackers to exploit.

Cryptography itself can be described as the constant war between hackers and cryptographic engineers. Or, that familiar legal battle with your ex-wife over her maintenance payments. After all, what works today may not work tomorrow. A proof of MD5 hash algorithm vulnerability is a very good example.

So if your task is to ensure your users’ data privacy, be ready to constantly update your functions to counteract the recent ‘breakthroughs’.

Let's imagine that you decided to google ‘best sauces for Wagyu steak’. You went through several web pages, and then on page two of the search results, you get this notification from your Chrome browser:

Something went wrong, that's for sure. What happened? Should you proceed to the page without a private connection?

An IT expert would surely reply:

The error that you got here was probably because of an SSL/TLS handshake failure.

SSL? TLS?? Acronyms you’ve no doubt heard before, but ones that nevertheless evoke a dreary sense of confusion in the untrained mind. In this article, we’ll try to explain what SSL/TLS is, how it works and at the very least, you’ll understand what that lock icon on the address bar is.

Where did TLS originate?

TLS stands for Transport Layer Security, and it is right now the most common kind of Web PKI. It’s used not only to encrypt internet browsing but also for end-to-end connection (video calling, messaging, gaming, etc.).

As for now, we expect almost any kind of connection on the internet to be encrypted, and if something is encrypted, we get an alert similar to that seen in figure A. But that wasn't always the case. If you go back to the mid-90s – very little on the internet was encrypted. Maybe that was because fewer people were using the internet back then, or maybe it was because there weren’t credit-card details flying all over the place.

The history of TLS starts with Netscape. In 1994, it developed Secure Socket Layer 1 – the grandfather of modern TLS. Technically, it fits between TCP and HTTP as a security layer. While version 1 was used only internally and was full of bugs, very quickly, they fixed all the issues and released SSL 2. Then, Netscape patented it in 1995 with a view to stopping other people patenting it so they could release it for free. This was a very odd yet generous move, considering what the real-life patent practice was at that time.

In 1995, the world was introduced to Internet Explorer, a browser that used a rival technology called PCT (Private Communications Technology), which was very similar to SSL. But as with any rivalry – there could only be one winner. In November 1996, SSL 3 was released, which, of course, was an improvement on SSL 2. Right after that, the Internet Engineering Task Force created the Transport Layer Security Working Group to decide what the new standard for internet encryption would be. It was subsequently renamed from SSL to TLS (as far as we know, this was because Microsoft didn't want Netscape to have dibs on the name). It actually took three years for the group to release TLS 1. It was so similar to SSL 3 that people began to name it SSL 3.1. But over time, through updates, the security level rose massively; bugs were terminated, ciphers were improved, protocols were updated etc.

But, how does it all actually work?

TLS is a PKI protocol that exists between two parties. They effectively have to agree on certain things to identify each other as trustworthy. This process of identification is called a 'handshake'.

Let’s take a look at a TLS 1.2 handshake, as an example.

First, let's load any webpage, then, depending on your browser, press the lock icon near the web address text field. You’ll be shown certificate info and somewhere between the lines you'll find a string like this:

This is called a Cipher Suite. It’s a string-like representation of our 'handshake' recipe.

So, let’s go through some of the things shown here:

• First, we have ECDHE (Elliptic-curve Diffie–Hellman), which is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. In layman’s terms, this is known as key exchange;
• The RSA is our Public Key authentication mechanism (remember, we need a Public Key for any PKI);
• AES256 refers to the cipher that we’re going to use (AES) and its' key size (256);
• Lastly, SHA384 is effectively a building block that is used to perform hash functions.

Now, the trick is to exchange all that data in just several messages via our 'handshake'.

What exactly happens when we go to a new web page?

After we establish a TCP (Transmission Control Protocol) connection, we start our handshake. As always on the web, the user (Client) is requesting data from the Server – so he sends a 'Client Hello' message, which contains a bunch of data including:

• The max TLS version that this Client can support so that both parties are able to 'speak the same language;
• A random number to protect from replay attacks;
• List of the cipher suites that the Client supports.

Assuming the Server is live, it responds with 'Server Hello', containing the Cipher Suite and TLS version it chose to connect with the Client + a random number. If the server can't choose a Suite or TLS version due to version incompatibility – it sends back a TLS Alert with a handshake failure. At this point, both the User and the Server know the communication protocol.

Keep in mind that the server is sending a Public key and a Certificate containing an RSA key. It’s important to know that the Certificate has an expiration date. You’ll understand why by the end of the article.

On top of that, the Server is sending a Server Key Exchange Message containing parameters for ECDHE with a public value. Very importantly, this Exchange Message also contains a digital signature (all previous messages are summarized using a hash function and signed using the private key of the Server). This signature is crucial because it provides proof that the Server is who they say they are.

When the Server is done transmitting all the above-mentioned messages, it sends a 'Server Hello Done' message. In Layman’s terms, that’s an ‘I’m done for the day, I’ll see you at the pub’ kind of message.

The Client, on the other hand, will look at the Certificate and verify it. After that, it will verify the signature using the Certificate (you can't have one without the other). If all goes well, the Client is assured of the Server’s authenticity and sends a Client Key Exchange Message. This message doesn't contain a Certificate but does contain a Pre-master Secret. It is then combined with the random numbers that were generated during the ‘Hello’ messages to produce a Master Secret. The Master Secret is going to be used for encryption at the next step.

It may seem very complicated now, but we’re almost done!

The next stage involves the Client sending the ‘Change Cipher Spec’ message, which basically says "I’ve got everything, so I can begin encryption – the next message I'll send you is going to be encrypted with parameters and keys".

After that, the Client proceeds to send the ‘Finished’ message containing a summary of all the messages so far encrypted. This helps to ensure that nobody fiddled with the messages; if the Server can't decrypt the message, it leaves the 'conversation'.

The Server will reply in the same way – with a Change Cipher Spec and a Finished message.

Handshaking is now done, parties can exchange HTTP requests/responses and load data. By the way, the only difference between HTTP and HTTPS is that the last one is secure – that's what the 'S' stands for there.

As you can see, it's incredibly difficult to crack this system open. However, that's exactly what we need to ensure security. Moreover, those two round trips that the data travels take no time at all, which is great; nobody wants their GitHub to take a month and a half to load up. By the way, the more advanced TLS 1.3 does all that in just one round trip!

Your connection is not private

When something goes wrong with TLS, you’ll see the warning that we demonstrated at the very beginning of this article. Usually, those are issues associated with the Certificate and its expiration date. That’s why your internet will refuse to work if you’ve messed around with the time and date settings on your device. But, if everything with the date and time is in check – never proceed to a website that triggers this warning, because most likely, between you and the server, somebody is parsing your private data.

Let’s imagine that somehow you’re in the driver’s seat of a start-up, and a successful one too. You’ve successfully passed several investment rounds and you’re well on your way to success. Now, big resources lead to big data and with big data, there’s a lot of responsibility. Managing data in such a company is a struggle, especially considering that data is usually structured in an access hierarchy – Excel tables and Google Docs just don’t cut the cake anymore. Instead, the company yearns for a protocol well equipped to manage data. The company yearns for LDAP.

What is LDAP?

The story of LDAP starts at the University of Michigan in the early 1990s when a graduate student, Tim Howes, was tasked with creating a campus-wide directory using the X.500 computer networking standard. Unfortunately, accessing X.500 records was impossible without a dedicated server. Additionally, there was no such thing as a ‘client app’. As a result, Howes co-created DIXIE, a directory client for X.500. This work set the foundations for LDAP, a standards-based version of DIXIE for both clients and servers – an acronym for the Lightweight Directory Access Protocol.

It was designed to maintain a data hierarchy for small bits of information. Unlike ‘Finder’ on your Mac, or ‘Windows Explorer’ on your PC, the ‘files’ inside the directory tree, although small, are contained in a very hierarchical order – exactly what you need to organize, for example, your HR structure, or when accessing a file. Compared to good old Excel, it is not a program, but rather a protocol. Essentially, a set of tools that allow users to find the information that they need very quickly.

Importantly, this protocol answers three key questions regarding data management:

— Who? Users must authenticate themselves in order to access directories.
— How? A special language is used that provides for query or data manipulations.
— Where? Data is stored and organized in a proper manner.

Let’s now go through these key questions in greater detail.

Who?

It’s bad taste to provide internal data to any old Joe. That’s why LDAP users cannot access information without first proving their identity.

LDAP authentication involves verifying provided usernames and passwords by connecting with a directory service that uses the LDAP protocol. All this data is stored in what is referred to as a core user. This is a lot like logging into Facebook, where you’re only able to access a user’s feed and photos if they’ve accepted your friend request, or if their profile has been set to public.

Some companies that require advanced security use a Simple Authentication and Security Layer (SASL), for example, Kerberos, for the authentication process.

In addition, to ensure the maximum safety of LDAP messages, as soon as data is accessed via devices outside the company’s walls, Transport Layer Security (TLS) may be used.

How?

The main task of a data management system is to provide “many things to many users”.

Rather than creating a complex system for each type of information service, LDAP provides a handful of common APIs (LDAP commands) to do this. Supporting applications, of course, have to be written to use these APIs properly. Still, the LDAP provides the basic service of locating information and can thus be used to store information for other system services, such as DNS, DHCP, etc.

Basic LDAP commands

Let’s look at the ‘Search’ LDAP command as an example, if you’d like to know which group a particular user is a part of, you might need to input something like this:

(&(objectClass=user)(sAMAccountName=BradleyC)
(memberof=CN=Perohouse,OU=Users,DC=perohouse,DC=com))

Isn’t it beautiful? Not quite as simple as performing a Google search, that’s for sure. So, your employees will perform all their directory services tasks through a point-and-click management interface like Varonis DatAdvantage.

All those interfaces may vary depending on their configuration, which is why new employees should be trained to use them, even if they’ve used LDAP before.

Where?

As we mentioned before, LDAP has the structure of a tree of information. Starting with the roots, it contains hierarchical nodes relating to a variety of data, by which the query may then be answered.

The root node of the tree doesn't really exist and can't be accessed directly. There is a special entry called the root directory specific entry, or rootDSE, that contains a description of the whole tree, its layout, and its contents. But, this really isn't the root of the tree itself. Each entry contains a set of properties, or attributes, in which data values are stored.

The tree itself is called the directory information tree (DIT). Branches of this tree contain all the data on the LDAP server. Every branch leads to a leaf in the end – a data entry, or directory service entry (DSE). These entries contain actual records that describe objects such as users, computers, settings, etc.

For example, such a tree for your company could start with the description of a position held, starting with you at the top as the director, finishing at the bottom with Joe Bloggs, the intern.

Each position would be tied to a person with a set of attributes, complete with links to subordinates. The attributes for a person may include their name, surname, phone number, email, in addition to their responsibilities. Each attribute would have a value inside, like ‘Joe’ for name and ‘Bloggs’ for surname.

The actual data contents may vary, as they totally depend on use. For example, you could have data issuing rights to certain people regarding the coffee machine. So, no Frappuccino for our intern Joe.

Sure, you can add more sophisticated data regarding each individual – their personal family trees, or even voice samples for instance, but typically, the LDAP would just point to the place where such data can be found.

Is it worth it?

LDAP is able to aggregate information from different sources, making it easier for an enterprise to manage information. But as with any type of data organization, the biggest difficulty is creating a proper design for your tree. There is always trial and error involved while building a directory for a specific corporate structure. Sometimes this process is so difficult that it even results in the reorganization of the company itself in favour of the hierarchical model. Despite this, for almost thirty years, the LDAP has held its title as the most efficient solution for the organization of corporate data.

Imagine you’re a system administrator at Home Depot. Just as you’re about to head home, you notice that your network has just authorized the connection of a new air-conditioner. Nothing too peculiar, right? The next morning, you wake up to find that terabytes of data including logins, passwords and customer credit card information have been transferred to hackers. Well, that’s exactly what happened in 2014, when a group of hackers, under the guise of an unassuming HVAC system, landed an attack that cost Home Depot over $17.5 million dollars, all over an incorrectly configured PKI. In this article, we’ll be conducting a crash course in PKI management.

So, what’s a PKI?

‘Public key infrastructure’ is a term that relates to a set of measures and policies that allow one to deploy and manage one of the most common forms of online encryption – public-key encryption. Apart from being a key-keeper for your browser, the PKI also secures a variety of different infrastructures, including internal communication within organizations, Internet of Things (IoT), peer to peer connection, and so on. There are two main types of PKIs:

•   The Web PKI, also known as the “Internet PKI”, has been defined by RFC 5280 and refined by the CA/Browser Forum. It works by default with browsers and pretty much everything else that uses TLS (you probably use it every day).

•   An Internal PKI – is the one you run for your own needs. We’re talking about encrypted local networks, data containers, enterprise IT applications or corporate endpoints like laptops and phones. Generally speaking, it can be used for anything that you want to identify.

At its core, PKI has a public cryptographic key that is used not to encrypt your data, but rather to authenticate the identities of the communicating parties. It’s like the bouncer outside an up-market club in Mayfair – you’re not getting in if you’re not on the list. However, without this ‘bouncer’, the concept of trustworthy online communication would be thrown to the wind.

So, how does it work?

PKI is built around two main concepts – keys and certificates. As with an Enigma machine, where the machine’s settings are used to encrypt a message (or establish a secure protocol), a key within a PKI is a long string of bits used to encrypt or decrypt encoded data. The main difference between the Enigma machine and a PKI is that with the latter, you have to somehow let your recipient know the settings used to encode the encrypted message.

The PKI gets its name because each party in a secured connection has two keys: public and private. A generic cipher protocol on the other hand, usually only uses a private one.

The public key is known to everyone and is used throughout the network to encode data, but the data cannot be accessed without a private key, which is used for decoding. These two keys are bound by complex mathematical functions which are difficult to reverse-engineer or crack by brute force. By the way, this principle is an epitome of asymmetrical cryptography.

So, this is how data is encrypted within a public key infrastructure. But let’s not forget that identity verification is just as important when dealing with PKIs – that’s where certificates come into play.

Digital Identity

PKI certificates are most commonly seen as digital passports containing lots of assigned data. One of the most important pieces of information in such a certificate relates to the public key: the certificate is the mechanism by which that key is shared – just like your Taxpayer Identification Number (TIN) or driver’s license, for instance.

But it’s not really valid unless it has been issued by some kind of entrusted authority. In our case, this is the certificate authority (CA). Here, there is an attestation from a trusted source that the entity is who they claim to be.

With this in mind, it becomes very easy to grasp what the PKI consists of:

•      A certificate authority, which issues digital certificates, signs them with its public key and stores them in a repository for reference;

•      A registration authority, which verifies the identities of those requesting digital certificates. A CA can act as its registration authority or can use a third party to do so;

•      A certificate database that stores both the certificates, their metadata and, most importantly, their expiration dates;

•      A certificate policy outlining the PKI's procedures (this is basically a set of instructions that allows others to judge how trustworthy a PKI is).

What is a PKI used for?

A PKI is great for securing web traffic – data flowing through the open internet can be easily intercepted and read if it isn't encrypted. Moreover, it can be difficult to trust a sender’s identity if there isn’t some kind of verification procedure in place.

But even though SSL/TLS certificates (that secure browsing activities) may demonstrate the most widespread implementation of PKI, the list doesn’t end there. PKI can also be used for:

•       Digital signatures on software;

•       Restricted access to enterprise intranets and VPNs;

•       Password-free Wifi access based on device ownership;

•       Email and data encryption procedures.

PKI use is taking off exponentially; even a microwave can connect to Instagram nowadays. This emerging world of IoT devices brings us new challenges and even devices seemingly existing in closed environments now require security. Taking the ‘evil air conditioner’ that we spoke about in the introduction as an example – gone are the days where we can take a piece of kit for face value. Some of the most compelling PKI use cases today centre around IoT. Auto manufacturers and medical device manufacturers are two prime examples of industries currently introducing PKI for IoT devices. Edison’s Electronic Health Check-up System would be a very good example here, but we’ll save that for a future deep-dive.

Is PKI a cure-all?

As with any technology – execution is sometimes more important than the design itself. A recent study by the Ponemon Institute surveyed nearly 603 IT and security professionals across 14 industries to understand the current state of PKI and digital certificate management practices. This study revealed widespread gaps and challenges, for example:

•       73% of security professionals admit that digital certificates still cause unplanned downtime and application outages;

•       71% of security professionals state that migration to the cloud demands significant changes to their PKI practices;

•       76% of security professionals say that failure to secure keys and certificates undermines the trust their organization relies upon to operate.

The biggest issue, however, is that most organizations lack the resources to support PKI. Moreover, only 38% of respondents claim they have the staff to properly maintain PKI. So for most organisations PKI maintenance becomes a burden rather than a cure-all.

To sum up, PKI is a silent guard that secures the privacy of ordinary online content consumers. However, in the hands of true professionals, it becomes a power tool that creates an encryption infrastructure that is almost infinitely scalable. It lives in your browser, your phone, your wifi access point, throughout the web and beyond. Most importantly, however, a correctly-configured PKI is the distance between your business and an imposter air conditioner that wants your hard-earned cash.

If you’re new to password managers, you might be wondering why they’re even necessary. To clear things up, we’ll explore three major password-related security challenges that businesses face and how a password manager, like Passwork, can help you and your business to work smart, boost security and reduce the stress of managing numerous credentials.

Digitalisation and human factor

The rapid shift to digital platforms, especially during the COVID-19 pandemic, has significantly increased attack vectors for cybercriminals. With so many people working from home, unaccustomed to using complex security tools, human error has become a major vulnerability. Imagine an entire wave of old-school office managers in their fifties buying laptops and working from home for the first time. Of course, it’s no surprise that cyberattacks are on the rise; in fact, phishing attacks skyrocketed in 2020, with 75% of organizations experiencing some form of attack.

Human error, in this sense, needn't be accepted when you’ve got a password manager on hand. When you access a website that requires a password stored by your password manager, it is presented automatically by the software. However, this only occurs when the webpage is authentic. Phishing attacks rely on false web pages that mimic the real thing, and whilst this may trick a user, a password manager can tell fact from fiction, every time. When the user doesn’t see his password pop up on the screen, he knows that he’s not in the right place. But what if the user decides to put in the password manually? Well, password managers are on the case; oftentimes, complex and unmemorable passwords are generated, and users are forced to rely on auto-input. Human error? Eliminated.

By eliminating human error through automation, Passwork helps ensure that your company’s sensitive information is never compromised by phishing attempts or careless mistakes.

Preparing for security audits

The benefits of password managers don’t end there. Preparing for security audits can be stressful, but solutions including and similar to Passwork makes the process smoother by significantly improving password hygiene. A key part of any security audit is evaluating the strength and management of passwords. Weak, old, or compromised passwords can raise red flags during an audit and expose your company to cyberattacks.

Password managers automatically alert users when passwords need to be updated—whether they're too weak, outdated, or compromised. This keeps your password security strong and helps your business pass audits with flying colors.

Additionally, and more importantly, password managers minimize human involvement wherever possible, and as has already been established, this is key to secure operations. Should an employee leave the company, Passwork will notify administrators to change any passwords that the former employee had access to, reducing the risk of data leaks. The automation of this process ensures that passwords are continuously updated without depending on manual efforts, preventing potential security oversights.

Handling absences and staff changes

On a similar note, temporary staff absences, rather than permanent personnel changes, can also cause problems for companies without password management software. If an employee is on vacation or out sick, it can become difficult for the rest of the team to access crucial files or systems, causing inefficiencies and delays. Let’s say you’ve gone away for a relaxing beach holiday in Bali. It’s unlikely that you’ll be on your phone responding to Sharon from accounting, who needs the password to your email account, right? Well, Sharon can’t access an important PDF that was sent by a client last week, so she has to ask them to send it again. It’s inefficient, unprofessional, and will cost your company time and money.

This is an issue that password managers can solve. With solutions like Passwork, employees no longer need to memorize passwords or jot them down in hidden places. Passwork securely stores them either on your local server or in the cloud, ensuring easy access and enhanced security. This means that they can be accessed by anybody with the appropriate security clearance. Business can run smoothly, regardless of staff absences, and you can get back to reading Sapiens with your mojito.

Conclusion

Solutions like Passwork are simply a necessity in the modern world, it's more than just a password manager—it's an essential tool for modern businesses looking to strengthen their security posture and improve operational efficiency. By automating password management, reducing human error, and offering centralized, secure access to sensitive information, Passwork helps businesses safeguard their data in a fast-evolving digital world. If you’re reading this, wondering whether your business is even big enough for such infrastructure, think again; don't wait—take the next step in securing your company’s data with Passwork.

Information technology is developing by leaps and bounds. There are new devices, platforms, operating systems, and a growing range of problems, which need to be solved by developers.

But, it’s not so bad—new development tools, IDEs, new programming languages, methodologies, etc., rush to help programmers. The list of programming paradigms is impressive, and with the modern multi-paradigm PL (e.g., C#), it is reasonable to ask: «What is the best way to handle it? What to choose?»

Let’s try to figure this answer out.

From where did so many paradigms come?

In fact, the answer has already been stated in this post—different types of tasks are now easier and faster to solve, using the appropriate paradigm. Accordingly, new types of problems have appeared with the IT evolution (or the old ones become relevant), and solving them using the old approach is not suitable and it is inconvenient, which resulted in rethinking things and the development of new techniques.

What to choose?

Everything depends on what is required. It is worth noting that all the development tools are different. For example, PHP with a «standard» set of modules does not support aspect-oriented programming. Therefore, the choice of methodology is quite closely linked to the development platform. Oh, and do not forget that you can combine different approaches, which leads us to the choice of stacking paradigms.

For paradigm categorization, I used to use four dimensions that are inherent in almost any task:

Data
Any program somehow works with data: stores, processes, analyzes, reports.

Actions
Any program should do something—the action is usually connected with the data.

Logic
Logic or business logic defines the rules that govern the data and actions. Without the program, logic does not make sense.

Interface
How the program interacts with the outside world.

We can go further and get deeper into this idea to come up with quality characteristics for these four measures, creating strict rules and adding in a little math, but this is perhaps a topic for another post. I think most system architects determine the characteristics of the data for a specific task on the basis of their knowledge and experience.

Once you analyze your problem to these four dimensions, it is likely that you will see that a certain dimension is expressed stronger than the other. And this in turn will determine the programming paradigm, as they usually focus on some singular dimension.

Consider this example

Orientation to the data (Data-driven design)

Data is in the consideration, rather than how they are related to each other

Types of suitable applications:

1. Grabbers/crawlers (collect data from different sources, save somewhere)
Various admin interfaces to databases; everything with a lot of simple CRUD operations.
2. Cases, when the resource is already defined, for example, it requires the development of a program and the database already exists and you can’t change the schema of the data. In this case, it may be easier to focus on what is already done, rather than creating additional wrappers over data and data access layers. Using an ORM often leads to data-driven, but it is impossible to say in advance if it is good or bad (see below).

Orientation to actions—imperative approaches to development

Event-driven Programming, Aspect-oriented Programming, etc.

Orientation to logic: Domain-driven design (DDD) and everything connected with it

Here we have an important subject area task. We pay attention to the modeling of objects, analysis of the relationships and dependencies. This is mainly used in business applications, and it is a declarative approach, and partly functional programming (tasks that are well described by mathematical formulas) is a part of DDD as well.

Orientation on the interface

Used when it is first important as the program interacts with the outside world.
An applications development with a focus only on the interface is a situation that is quite rare. Although some of the books I’ve read mention the fact that such an approach was considered seriously, and is based on the user interface, meaning it takes what the user sees directly and, on this basis, designs the data structures and everything else.

Orientation to the user interface in business applications is often manifested indirectly. For example, the user wants to see the specific data that is difficult to obtain due to what additional structures the architecture acquires (e.g., forced redundancy data). Formally, event-driven programming is included here.

What about real life?

Based on my experience, I can say that two approaches are indicated: focus on data (data-driven) and focus on logic (domain-driven). In fact, they are competing methodologies, but in practice can be combined in symbiosis, which is often known as anti-patterns.

One of the advantages of data-driven over domain-driven is the ease of use and implementation. Therefore, data-driven is used where it is necessary to apply the domain-driven (and often this happens unconsciously). Problems arise from the fact that the data-driven is hardly compatible with the concepts of object-oriented programming (of course, if you do use OOP). In small applications, these problems are almost invisible. In medium-sized applications, these problems are already visible and begin to lead to anti-patterns. On major projects, problems become serious and require appropriate action.

In turn, domain-driven wins on major projects, but on small, it complicates the solution and requires more resources for development, which is often critical in terms of business requirements (to bring the project to the market «asap», for a small budget).

To understand the differences in the approaches, consider a more concrete example. Suppose we want to develop a system of accounting for sales orders. We have things such as:

1. Product
2. Customer
3. Quote
4. Sales Order
5. Invoice

Deciding what the scope is at a glance, we begin to design the database. Create the appropriate tables, run the ORM, generate essential classes (well, in the case of a smart ORM, put this scheme somewhere separately, for example, XML, and generate a database and essential classes). Finally, we get an independent class for each essence. Enjoy life; it’s easy and simple to work with objects.

Time passes, and we need to add additional logic in the program, for example, to find the products with the highest price. There may already be a problem if your ORM does not support external communication (i.e., essential classes do not know anything about the context of the data). In this case, it is necessary to create a service, which is a method, to return the suitable product for the order. But our good ORM can work with external relations, and we simply add a method to the class order. Enjoy life again; the goal is achieved, the method is added in a class, and we have almost the real OOP.

Time passes, and we need to add the same method for the quote, for the invoice, and for other similar entities. What to do? We can simply add this method in all classes, but it will, in fact, code duplication and backfire with the support and testing. We want to avoid complicating and simply copy methods in all classes. Then there are similar methods, and the essential classes begin to swell with the same code.

Time passes, and there is a logic that can’t be described by the external connections in the database. In this case, there is no way to place it in an essential class. We begin to create services that perform these functions. As a result, we find that the business logic is scattered by essential classes and services, and understanding where to look for the correct method is becoming increasingly difficult. Decide to refactor and to move out repetitive code in services—highlight common functionality into the interface (for example, make the interface IProductable, i.e., something that contains products). Services can work with these interfaces, thereby winning a little in abstraction. But it does not fundamentally solve the problem; we get more methods in the services and solutions for the unity of the painting techniques to transfer all the essential services in the classes. Now we know where to look for methods, but our essential classes lost any logic, and we got the so-called «anemic model.»

At this stage, we are completely gone from the concept of OOP—the object stores only the data, all the logic is in separate classes, and there is no encapsulation and no inheritance.

It is worth noting that this is not as bad as it may seem—nothing prevents implementing unit testing and the development through testing (TDD) to integrate dependency management patterns (IoC, DI), etc.. In short, we can live with it. Problems arise when the application will grow large—when we get so many entities that it’s unrealistic to keep in mind. In this case, the support and development of such an application would be a problem.

As you have probably guessed, this scenario describes the use of the data-driven approach and its problems.
In the case of domain-driven, we would proceed as follows. Firstly, there is no database designing in the first stage. We would need to carefully analyze the problem domain context, model it, and move on to OOP language.

For example, we can create an abstract model of the document, which would have a set of basic properties. Inherit from this a document that has the products, to inherit from this a «payment» document, with the price and billing address, and so on. With this approach, it’s pretty easy to add a method that finds the most expensive product—we just add it to the appropriate base class.

As a result, the scope of the problem will be described using the OPP to the fullest.
But there are obvious problems: how to store data in the database? Actually, it will require the creation of a function for mapping data from models to the fields in the database. Such a mapper can be quite complex, and when you change models, you also need to change the mapper.

Moreover, you are not immune from errors in the modeling, which can lead to complex refactoring.

Summary:
Data-driven vs Domain-driven

Data-driven

Pros

1. Allows you to quickly develop an application or prototype
2. Convenient to design (code generation, scheme, etc.)
3. Can be a good solution for small or medium-sized projects

Cons

1. Can lead to anti-patterns and loss of the OOP
2. Leads to chaos on large projects, complex support, etc.

Domain-driven

Pros

1. Use the power of OOP
2. Allows you to control the complexity of the scope (domain)
3. There are a number of advantages that are not described in the article, for example, the creation of the domain of language and the use of BDD
4. Provides a powerful tool for developing complex and large solutions

Cons

1. Requires significantly more resources for the development, which leads to greater solutions cost
2. Certain parts are becoming harder to support (mapper data, etc.)

So, what the hell should I choose?

Unfortunately, there is no single answer. Analyze your problem, resources, prospects, goals, and objectives. The right choice is always a compromise.

Positioning is an important aspect

Positioning is so important that, if this stage is skipped, all other efforts of promotion of the product could be ruined. Good positioning should be short, clear, and understandable. Therefore, it is often described in one sentence or is made to fit in a tweet. Positioning should be directly related to the main problem that the product will solve for the users.

The difficulty is that many a-times, the product generally solves various problems for different users. For example, an online accounting system providing the same capabilities solves different problems for the entrepreneur and accountant. As to the question «Who are you?», different answers may be given, depending on who is posing the question. Positioning is closely related to the target audience segmentation. Often, I have heard startups saying that their product is made for all users of the Internet, or something like that, which is definitely an outlandish type of segmentation.

Begin to break your users into segments. Try implementing any different characteristics like gender, age, income level, interests, etc. The task to break all users into segments is performed in such a way that all were uniform within a single segment. That is, from the perspective of the product, all users of one segment are like twins and are indistinguishable to a significant extent.

Take one segment user and tell him about the product. Then afterward, take any other user of the same segment, and their stories about the product should be similar. Begin to divide users from the largest to smallest. Specify what problem your product solves for each segment. If more than one problem is obtained from a single segment, the segment shall be divided into further sub-segments.

As a result, you should get:

1. The segment and its characteristics (feature set)
2. The problem is solved by the users of that segment
3. Positioning for this segment. In this case, the product can be position in a single sentence.

From this scheme, you automatically get ready-made advertising campaigns for Yandex, VKontakte, Google, Twitter. And you can understand where to look for leads and what attraction channels to use based on segment performance. By looking at the segments tree, you can go in the opposite direction, summarize a number of problems, and get the main product positioning. And a detailed list will be a good start for the development of the Landing page.

Take, for example, the development of websites, the likes of ‘heavily worked-on websites, will soon be performed using innate abilities.

For whom?

1. For all the sites which may need this? — Well, yes.
2. For business? — Yeah right!
3. For business owners that have heard something about the Internet, interested in finding customers? — Getting Warmer
4. Does this business have a site?
5. Is this a recently established business?
6. Volumes (for example, how many employees)
7. Lines of business

Eventually, we obtain a segment such as the following:

1. Recently established company (6-12 months old)
2. with a small staff (10-20 people).
3. Recently launched, no site at the moment hasn’t met targets as yet, and the like,
4. are not willing to devote a lot of money on the development of the site
5. On the question of whether or not a site is needed, the most likely answer is, «Well, of course, it is needed»
6. Does not plan to actively attract customers via the Internet.

The situation is one of those «websites needed, well so that we owned one.» The problem is that this is not represented on the Internet Positioning: «We are setting up a website for business start-ups on the Internet for 1 week and for so many rubles.» This is not ideal, but the point is clear. Offering affordable, or perhaps typical or conventional solutions, Landing pages, with minimal customization, cheap but good and fast. It is worth noting that in the site-building world, young companies just need to be positioned and well-niched. Sites solve many problems and are needed for numerous problems to be solved, so cramming the site under a one-size-fits-all does not work.

So, in summary:

1. Divide your customers into segments as per the problems that your product solves. The better the homogeneity of the segment, the better the result (but without fanaticism)

2. Check № 1 — segment should easily explain what you have to offer. Without any "and"s and "or"s.

3. Checking № 2 — product positioning for the segment, tagline, the main message, are all to be contained within the tweet.

4. Segmentation and positioning are closely linked. One may be used to create the others, and vice versa.

5. Segmentation and positioning give insight into what customers to look for, how to look, where to look for them, and what particular offer to give them. You can write a statement for Sales.

6. Structuring allows you to identify the main problems to be solved by the product, and a host of other artifacts that can be used, for example, for setting up a Landing page.

After initializing their first releases or MVP (first minimal product-release), startups are faced with the challenge of promoting and marketing on the Internet. If they do this through Yandex or Google AdWords, a single click designed to attract customers can cost $1 or more, and the cost of publishing a single article onto a popular media site can be more than $ 1,000 per campaign. New startups, even when heavily propped-up investment-wise, and enjoying huge financial backing, cannot afford to walk on such a grand and costly scale.

Or they can, but here is a well-established fact: all funds are consolidated only after a couple of months; whether there were any sales or not, and they ran out of money for further product development.

Very often, startup beginners say: "We do not know how much we need for marketing. How do we evaluate this?", or: "We need ten million on marketing, hmm, no, let's make it twenty ...".

Then, they quickly start buying ads and spending money in vain, and slowly begin to realize that marketing is one hell of a very expensive endeavor. You may have a great product, everyone may like it, everyone may be dying to use it, but then, it is necessary to spend a lot of money on advertising. Well, afterwards, they start looking for an investment specifically for marketing.

So, rounding up: marketing and promotion of IT-startups on the Internet proves to be expensive, unclear and unpredictable.

Familiar?

In fact, the promotion of start-ups is actually understandable and predictable. Whether it will be costly or not depends on each particular situation.

It is really quite possible to promote IT-startups using only little or no financial investment at all. In this case, impressive and surprising results can be achieved.

In the open world, these techniques are called growth hacking

And, just a small faq on explosive promotions:

1. Wow, is it really possible for any project to be able to directly unleash a host of ads without money, and without doing anything at all?
− No, not any project. A lot of work still has to be done. But for many projects, not a lot of money is spent.

2. So, if not ANY project, then which ones?
− First of all, IT-startups or projects that are well-integrated on the internet. But in general, the general principles apply everywhere.

3. So, purchasing advertising space will be a thing of the past?
− Yes and no. Advertising will always be a great help if you can afford it, and sometimes, may be the only option.

4. Do I still have to learn about marketing or hire a marketer?
- You needs to know the fundamentals. Growth hacking and marketing are related, but not deeply. This a kind of side-approach, where your brains, simple logic, entrepreneurial skills; all really matter. Certainly not misgivings.

How growth hacking works

The basic idea of the explosive product is very simple and logical. If your product is good, its users will talk about it themselves. They only need help to do that. Practically almost all the techniques can be reduced to one single aim: to increase virality without any cash expenditures.

The obvious pre-condition is that your product really needs to solve user problems, should be necessary, useful and convenient. You must have a high-quality product.
I am sure that all startups find their desired product, but this is not always the case.

Explosive advertising works well for IT-startups, because users can easily talk about it and attract other users, the internet is there to help. In addition, explosive advertising is a pack of little tricks that helps you get close to your audience; motivate, talk about the product, test ideas, increase conversion, and so on.

In summary,

1. "Standard way" - more money into advertising, greater audience reach, more new users.

2. Explosive advertising - users themselves are involved together with their friends. Avalanche exponential growth. Quality product needed.

3. Divide all your customers into particular segments according to the problems that your product solves. The more homogeneous the segment, the better (but without fanaticism)

4. Check №1 - It is very easy to explain what you have to offer if this is done segment by segment. Without any "and" and "or".

5. Checking №2 - Product positioning for the segment, tagline, the main message should all be contained within the tweet.

6. Segmentation and positioning are closely linked. One can lead to the other, and vice versa.

7. Segmentation and Positioning give insight into what customers are looking for, how to look, where to look for that particular offer. You can write a statement for sales.

8. Structuring allows you to identify the main problems to be solved by the product, and a host of other artifacts that can be used, for example, to create a Landing.

A couple of guesses—your mother's maiden name, your date of birth, your pet's name. And Bam! Your password is stolen.

Password theft is becoming more common every day. While one of the most notorious incidents was the 2014 Russian hacker incident that compromised more than 1.2 billion passwords, this is far from an isolated event. There are news stories about password-related breaches almost every day. And yet, many people continue to use weak, easily guessable passwords.

Why? Because they’re easy to remember. But as simple as these passwords are for you, they’re even easier for hackers to crack. This is a serious concern for businesses, where cybersecurity is paramount.

Why Security Policies Alone Aren't Enough

Large enterprises often implement password policies requiring employees to use strong passwords. However, since it's easier to remember short passwords, many employees disregard the policies and choose weak passwords. A policy alone isn’t much help here.

The solution? A corporate password manager that ensures strong, unguessable passwords are used across the company. By using the right technology, you can significantly reduce the risk of a data breach.

While a corporate password manager can choose passwords for you, how do you choose the right one for your business? Here are some tips to help you find the best software for your enterprise.

Tip #1: Choose the Right Solution for Your Enterprise

Password management solutions typically come in two forms: SaaS (cloud-based) or on-premise. Both have their advantages, depending on your company’s needs.

• SaaS (Software-as-a-Service): This option is managed by the provider, and you typically pay a subscription fee based on the number of users or the level of service. SaaS solutions are great for small- to mid-sized businesses, as they offer flexibility, scalability, and minimal setup costs.
• On-Premise: With an on-premise solution, the software is hosted on your company’s own servers. While there’s a higher upfront cost for hardware and software licenses, this option is ideal for larger enterprises that require full control over their data for compliance or security reasons.

Both options have their merits, so choose a vendor that offers both SaaS and on-premise solutions. This way, you can make a decision based on your company’s specific needs, ensuring you have the right balance between cost, security, and scalability.

Tip #2: Identify Potential Vulnerabilities

A critical feature of any corporate password manager is its ability to safeguard your data against vulnerabilities. Before committing to a solution, take the time to identify any weak points in the software.

Here’s a quick test: Sign in to the password manager and press F12 to open the browser’s developer console. In the “Network” tab, check for any external requests, like analytics scripts or third-party integrations. A secure password manager should not allow external third-party scripts that could expose you to cross-site scripting (XSS) or other attacks.

When third parties are allowed to call into the system, they can make the system vulnerable. Whether you prefer a SaaS password manager or an on-premise password manager, it should hold all sensitive information in such a way that external applications cannot access them.

Tip #3: Verify Encryption Standards

The password manager should store all passwords in an encrypted form. To verify this, use the browser’s developer tools again (F12 → Network tab). Now open any website where you need to sign in. Save the password in the password manager. Check whether the password appears as plain text or in encrypted form.

If it’s stored in plain text, the system is vulnerable to hacks. Strong encryption is essential. Look for password managers that use AES-256 encryption combined with an RSA handshake, which is the gold standard for secure data encryption.

Different password managers have different encryption standards. The highest cipher is AES-256 with an RSA handshake. This is military-grade encryption and is virtually unhackable. If your corporate password manager provides this level of encryption and owns its own servers, you don’t have to worry about the security of your information.

Tip #4: Choose a Vendor with Transparent Policies

When selecting a password manager, transparency is key. Check the vendor’s website for whitepapers and documentation on the algorithms and cryptography they use. Vendors with open-source or auditable code are preferable, as they demonstrate a commitment to transparency and security.

Zero-knowledge encryption is another critical feature. This means that the vendor has no access to your master password or any of your sensitive data. For instance, Passwork ensures all passwords are stored in encrypted vaults using a 256-bit cipher, making them accessible only to the user.

Opting for an open-source solution is a smart move, as it allows you to inspect the code and confirm that the cryptography being used is reliable and secure.

Tip #5: Ensure Auditability

If you opt for an on-premise solution, auditability is important. You should be able to inspect and audit the internal code to verify that it meets your company’s security standards.

Regular password audits are also essential for maintaining a secure system. A good password manager will automatically notify you when passwords need to be updated due to age or reuse across multiple services. This feature helps maintain optimal security across your entire organization.

If the code is open-source, you may even have the ability to customize it. However, be cautious, as making changes to the code can introduce instability. Always consult with the vendor before making any significant modifications.

Tip #6: Implement Two-Factor Authentication (2FA)

A reliable corporate password manager should support strong two-factor authentication (2FA) options to enhance security. Passwords alone aren’t always enough to safeguard sensitive data, as they can be stolen or cracked. 2FA ensures that even if a password is compromised, an additional authentication factor—such as a code sent to your phone or an authentication app—protects your accounts.

When selecting a password manager, ensure it integrates with a variety of 2FA methods, such as time-based one-time passwords (TOTP) or SMS codes. Implementing 2FA will greatly reduce the risk of unauthorized access to your corporate accounts, making it an essential security measure for any business.

Tip #7: Test the SSL Security

Advanced corporate password management tools use Secure Sockets Layer (SSL). The SSL transfers data securely between the client and the server. Passwork uses SSL along with AES-256 bit encryption and RSA handshake to ensure your data is encrypted according to the highest standards.

There are several online tools to check if there are any potential issues with the SSL quality of the password manager. With tools such as SSL Labs and SSL Checker, you can find out if the SSL certificates of the password manager are valid.

Tip #8: Look for Flexibility Across Platforms

A good corporate password manager should work seamlessly across all platforms and devices your employees use. Whether it’s desktop or mobile, macOS, Windows, iOS, or Android, the solution should offer compatibility with all major operating systems.

Additionally, ensure the password manager offers browser extensions for popular web browsers such as Chrome, Firefox, Safari, and Edge. Syncing across devices is another crucial feature. If an employee saves a password on their desktop browser, it should automatically be available when they log in on their mobile device.

The Bottom Line

There are several corporate password managers available, but make sure you choose the best one. Your password manager should not only be secure but also adaptable to your company’s needs. If you find a password manager that meets all the criteria listed above and is affordable, choose it to safeguard your passwords.

Remember, security isn’t an area where you can afford to cut corners. Your enterprise passwords are extremely important so don’t compromise on quality. Choose password manager that meets all your security requirements, including strong encryption, transparency, auditability, and two-factor authentication.

As the saying goes, “If you’re not paying for the product, you are the product.” Make the right choice by selecting software that keeps your company’s details safe. It not only simplifies things for your employees but also ensures your valuable information remains secure from prying eyes.
