The Kaiji malware was designed by a developer based in China to launch DDoS attacks according to researchers.
The Internet of Things (IoT) has revolutionized the way we interact with the digital world. From smart refrigerators to connected thermostats, these devices offer convenience and automation.
However, with this growing network of interconnected devices comes a new layer of vulnerability: malware specifically designed to target them.
Enter Kaiji Malware: A New Player in the DDoS Game
In 2020, security researchers stumbled upon a new strain of malware dubbed “Kaiji.” Named after a character in a Japanese manga series, Kaiji was unlike other IoT malware encountered before. Here’s what makes it stand out:
Developed for Disruption: Researchers believe Kaiji was designed by a developer based in China primarily to launch distributed denial-of-service (DDoS) attacks. These attacks overwhelm targeted servers with a flood of traffic, rendering them inaccessible to legitimate users.
Targeting the Vulnerable: Kaiji primarily spreads through SSH brute-force attacks. This involves systematically trying different usernames and password combinations to gain unauthorized access to vulnerable servers. It specifically targets the “root” user account, granting it complete control of the system if successful.
Built for Persistence: Once Kaiji gains access, it utilizes a bash script to establish a foothold on the infected system. This script creates a space for the malicious code to operate and ensures its continued presence even after a system reboot.
A Language Shift: Most IoT malware is written in familiar languages like C or C++. However, Kaiji deviates from the norm, being built from scratch using the Go programming language (Golang). This choice offers advantages like portability and ease of development, potentially signalling a growing trend among malware creators.
DDoS Arsenal: Kaiji boasts a repertoire of DDoS attack techniques. These include SYN floods, IP spoofing (making it appear as if the attack originates from a different source), and an SSH brute-force module to propagate the infection further. Additionally, it can exploit unpatched vulnerabilities in targeted systems, expanding its reach.
A Work in Progress: While capable of launching diverse attacks, Kaiji lacks the sophistication of some established botnets. Researchers believe it’s still under development, lacking complex functionalities found in its counterparts.
The emergence of Kaiji highlights the ever-evolving threat landscape targeting IoT devices. Here are some crucial steps you can take to safeguard your devices:
Secure Your SSH Access: If you use SSH on your devices, ensure you have strong, unique passwords and enable two-factor authentication whenever possible. Turning off password-based authentication and relying on key-based access further strengthens security.

VPN Vs SDP – What Are The Differences?
A VPN is a service that grants you a safe, private, and secure browsing experience. Its primary function is to route your connection through a server to hide your online activities. It encrypts your data and then sends it to the VPN server.
The data reaches the destination from the VPN server, be it a streaming platform or a bank website. The destination sees only the data coming from the VPN server’s location, not your actual location.Â
An SDP, on the other hand, is a new approach to cybersecurity. It is a network security framework that provides secure and safe access to different enterprise apps. Although the word “perimeter” creates confusion here, it simply refers to an element that sets limits, such as firewalls or demilitarized zones. Â
Unlike traditional architectures that separate an enterprise network from the real world using a fixed perimeter, an SDP creates a dynamic one-to-one network connection between the user and the resources accessed. Other unauthorized network resources remain inaccessible.Â
As the name suggests, an SDP is directly implemented on end-user devices, servers, or gateways. But it can be deployed as a stand-alone product or as a server.Â
You’ve probably asked which of the two technologies is better: VPN or SDP. The answer depends on the situation. But hopefully, after enumerating some points, you can make a choice.Â
VPNs Are an Outdated TechnologyÂ
Two decades ago, VPNs came onto the online scene. They aimed to ensure online security by providing a safe, point-to-point connection.Â
Yes, VPN providers were successful in reaching their aim. They developed tunnels through which encrypted data is sent and processed. But with demands for security getting higher and higher, it seems that VPNs can no longer keep up.
They cannot handle the complexities involved in the use of 5G networks and IoT technologies. Not to mention, they are still vulnerable to several threats, including the NotPetya malware.Â
It is true that the installation of PC cleaning software and tools, as well as the use of Android cleaners, can protect us against vulnerabilities and threats. But up to what point will you be relying on them?Â
The security breaches today are becoming worse, to the point where they don’t just disrupt personal activities but ruin the functioning of entire organizations, too. It comes as no surprise that many are slowly migrating to SDPs.Â
SDPs Can Streamline Network Access RulesÂ
In addition to improving cybersecurity, SDPs can streamline the rules in granting users access to a particular network. This is very important in eliminating the problem involved in the creation of too many rules.Â
SDPs can be set to allow short-term access rules and eliminate them when they are already redundant. The fewer rules to deal with, the lower the network access restrictions.Â
This feature not only improves visibility but also allows better control. In just a few minutes, SDPs can already generate rules. This is quite useful for network auditors and administrators.Â
VPNs Are Quite Inconvenient to UseÂ
Anyone who has used a VPN knows that it can sometimes operate slowly and unreliably. For instance, if you are accessing a geo-restricted website, you must connect and disconnect to a VPN server. If you have limited time, then this can be frustrating.Â
VPN management can become more complicated, especially when dealing with cloud migration. IT administrators need to coordinate and configure VPN policies. They also need to manage firewall policies. Though there are many PC repair tips and tricks they can use to ensure they don’t mess up, we can’t deny that one wrong configuration and the VPN won’t work.Â
SDPs Are Easier to Manage
Any organization that has just expanded and transitioned from having a centralized data center to multiple cloud deployments can attest to how complex it is to manage VPNs. Not only do IT administrators need to configure VPN settings and firewall policies, but they also need to synchronize them across different locations.
Unlike VPNs, SDPs are easier to manage. They offer a simpler administration and management process. Administrators can directly onboard and add a network resource to an SDP platform. They can also manage all settings and policies in the cloud. This means the need to sync and configure across various locations is avoided.
An SDP Has an Unlimited Growth Potential
Yes, you read that right. Organizations and companies will never have to worry about expansion with an SDP solution. No matter how many users are added and regardless of the load of processes needed, SDPs can smoothly scale in the cloud. They seamlessly bypass the need for powerful hardware.
VPNs Are Not That Flexible
A VPN can offer flexibility at a certain level as it can access different sites and connect to different data centers and virtual cloud networks. However, it is worth noting that the connection options are often resource-intensive. Even worse, tapping into them drives up the costs. No organization would want that.
You have already used a VPN service. Most of the time, it was probably okay while using it. But you cannot deny that it, too, got notoriously slow and reliable at some point.Â
With an SDP, the user experience is quite different. It is because it connects to a global network of points of presence (PoP) that provides a sturdy backbone, reducing latency and optimizing the process of routing data.
VPN Vs. SDP – Which Is Reliable?
Whether to use a VPN or an SDP depends on you. You might still want to choose VPNs because they’ve withstood the test of time, and many of them come with new and unique online security features. But let’s not forget that, like SDPs, they also started to shake. The world may not know much about SDPs yet, but they might take over the whole cybersecurity realm in due time.Â
And now that you know a lot about SDPs, you might want to take action. After all, it’s evident that the internet is becoming a place filled with risks and vulnerabilities. While reliable VPN solutions exist, SDPs offer entirely safe network access. Â
Choosing Between VPN and SDP
The best choice for you depends on your specific needs. Here’s a quick guide:
Choose a VPN if you need a simple solution for securing remote access to your entire network.
Choose an SDP if you need granular access control for specific applications and resources, require detailed user activity logs, and prioritize zero-trust security.
Additional Considerations
Integration with existing infrastructure: Consider how easily the solution integrates with your security and identity management systems.
Deployment complexity:Â Evaluate the time and resources required for setup and ongoing management.
User experience:Â Think about the ease of use for your employees and how it might impact their productivity.
By carefully considering these factors, you can choose the secure access solution that best meets your needs and security requirements.
Cybersecurity is constantly evolving, but the question is, are you willing to keep up?

Today, we will answer the question – what is cryptoviral extortion? Also, we will show you how to prevent it.
Cryptoviral extortion dates back to the late ’80s and early ’90s when the PC Cyborg/AIDS Information was spread to unsuspecting companies and businesses utilizing floppy disks. It was more of a classic example of the use of phishing/spamming.
The installed ransomware encrypts users’ hard drives, hides directories, and encrypts the file names in the system’s root directory, making the system unusable without decryption.
The author of the AIDS Information Introductory Trojan requested a ransom between $189 and $378 to be paid to a Panama post box before decrypting the files. He was later arrested based on a physically traceable address.
The 21st century makes payment anonymous and untraceable through the use of cryptocurrencies. This has encouraged the creation of more sinister crypto-viruses like the Teslacrypt, CTB-Locker, and Cryptowall, resulting in billions of dollars of annual loss to cybercrime.Â

The attack typically unfolds in these steps:
Infection:Â Malicious software (malware) infects your device. This malware can be disguised as legitimate software, arrive through phishing emails, or exploit vulnerabilities in your system.
Encryption: The malware employs a sophisticated encryption technique called public-key cryptography. This creates a two-key system: a public key is used for encryption, and a private key is required for decryption.
File Inaccessibility: The malware utilizes the public key to encrypt your essential files, rendering them inaccessible. This could include documents, photos, videos, financial data, or anything valuable.
Ransom Demand: A message on your screen informs you that your files are encrypted and demands a ransom payment (often in cryptocurrency) to regain access.
What Makes Cryptoviral Extortion Different?
Unlike traditional viruses that might damage or corrupt files, cryptoviral extortion leverages public-key cryptography. Here’s what sets it apart:
Public-Key Encryption:Â The attacker possesses the public key, which encrypts your files. Without the private key (held by the attacker), decryption becomes nearly impossible for most users.
Targeted Attacks: Cryptoviral extortion can target specific individuals, organizations, or entire networks, maximizing the impact and potential ransom payout.
Common Delivery Methods
Cryptoviral extortion attacks can be launched through various means, including:
Phishing Emails:Â Deceptive emails disguised as legitimate sources may contain malicious attachments or links that trigger the malware download.
Malicious Websites:Â Visiting compromised websites can unknowingly download malware onto your device.
Software Vulnerabilities:Â Outdated software with unpatched vulnerabilities can create openings for attackers to exploit and deploy malware.
Cryptoviral extortion, a form of cybercrime, involves hijacking your data and demanding a ransom to get it back.
Here’s a breakdown of the Cryptoviral extortion process:
1. Key Generation
The attacker creates a pair of cryptographic keys – a public key and a private key. Think of these keys as a complex lock and key system. The public key is widely distributed, while the private key is kept secret.
2. Weaponizing the Virus
The attacker embeds the public key into a malicious program called a “crypto-virus” or “ransomware.” This program becomes the weapon used to encrypt your files.
3. Spreading the Infection
The crypto-virus can infiltrate your system through various means, such as phishing emails, infected downloads, or even physical media like USB drives. Once inside, it encrypts your data on your hard drive and local directories.
4. Encryption with a Twist
Here’s the twist: the crypto-virus utilizes a two-key encryption process. It generates a random, temporary symmetric key unique to your system for encrypting your files. This symmetric key acts like a single key for all your files.
5. Double Lock
The twist deepens. The crypto-virus then encrypts the temporary symmetric key using the attacker’s public key. This creates an “asymmetric ciphertext,” essentially a complex, scrambled version of the symmetric key. Imagine locking a regular (symmetric) key inside a high-security safe (public key).
6. The Ransom Note
Once the encryption is complete, the crypto-virus displays a ransom message on your screen. This message typically includes:
The asymmetric ciphertext (the scrambled key)
Instructions on how to contact the attacker
Information on how to pay the ransom
7. Paying the Ransom (Optional)
Here’s where the extortion comes into play. The victim, desperate to regain access to their files, might consider paying the ransom. If they do, they send the payment and the asymmetric ciphertext to the attacker.
8. Decrypting the Key
If the attacker receives the payment, they use their private key (remember, the other half of the lock-and-key pair they kept secret) to decrypt the asymmetric ciphertext. This process unlocks the scrambled temporary symmetric key.
9. Regaining Access (Maybe)
In theory, the attacker sends the decrypted symmetric key back to the victim. The victim can then use this key to decrypt their files and regain access. However, there’s no guarantee the attacker will keep their promise and send back the decryption key.
Remember: Paying the ransom doesn’t guarantee your files will be restored. It also encourages cybercriminals and funds their malicious activities. Prevention through backups and robust security practices is the best defence against cryptoviral extortion.
Here are some essential best practices to prevent cryptoviral extortion:
1. Backup Religiously
This is the golden rule of data protection. Maintain regular backups of your critical files on an external hard drive or a reputable cloud storage service like Google Drive or Microsoft OneDrive (both offer free 15GB plans with upgrade options for larger storage needs).
A recent backup ensures you can restore your data quickly without succumbing to extortion demands.
2. Phishing Awareness: Be Wary of Digital Bait
Phishing emails are a standard method for cryptoviral attacks. Attackers disguise malicious links and attachments as legitimate communications, tricking you into clicking and infecting your system. Here’s how to stay vigilant:
Scrutinize Email Addresses and Sender Names:Â Be wary of emails from unknown senders or addresses with typos or inconsistencies.
Don’t Click Blindly: Hover over links before clicking to see the destination URL. Suspicious URLs with strange characters or irrelevant domains are red flags.
Don’t Open Unfamiliar Attachments: Avoid opening unknown files unless you’re expecting an attachment from a trusted source.
3. Antivirus with Ransomware Protection: A Digital Shield
Reputable antivirus software with built-in ransomware protection is a crucial line of defence. These programs can detect and block malicious software before it encrypts your files.
4. Secure Browsing Habits: Navigate the Web with Caution
Not all websites are created equal. Some harbour malware and exploit vulnerabilities in outdated software. Here are some safe browsing practices:
Stick to Reputable Websites:Â When downloading software or visiting unfamiliar websites, prioritize established and trustworthy sources.
Beware of Free Downloads:Â If something seems too good to be true, it probably is. Free software downloads from untrusted sources can be laced with malware.
Keep Your Browser Updated:Â Just like your operating system, update your web browser regularly. These updates often include security patches to address vulnerabilities exploited by malware.
5. Software Updates: Patching the Gaps
Software updates often contain critical security patches that fix vulnerabilities cybercriminals can exploit. Here’s how to stay on top of updates:
Enable Automatic Updates: Configure your operating system and software applications to update automatically whenever possible.
Review Update Notifications:Â Don’t ignore update notifications. Take the time to install them promptly to ensure your software remains secure.
Following these preventative measures can significantly reduce your risk of falling victim to cryptoviral extortion. Remember, proactive defence is the best defence against cyberattacks.
Can Antivirus Protect You From CryptoViral Attack?
Antivirus software plays a vital role in cybersecurity, but its effectiveness against cryptoviral attacks is nuanced. Here’s a breakdown of its capabilities:
Defence Against Known Threats: Antivirus programs effectively detect and block established forms of crypto-viruses. They can identify characteristic patterns in file encryption behaviour associated with known malware.
Limitations Against New Threats: Cybercriminals are constantly evolving their tactics. Zero-day attacks exploit previously unknown vulnerabilities and bypass traditional antivirus detection. Newer strains of crypto-viruses might be undetectable until security researchers identify and develop countermeasures.
So, is Antivirus Enough?
While antivirus software provides a valuable layer of protection, it shouldn’t be considered a foolproof solution against cryptoviral extortion. Here’s why a comprehensive approach is essential:
Backups are Your Safety Net: Regularly backing up critical data to an external drive or a cloud storage service is the ultimate defence. Even if a crypto-virus infects your system, you can restore your files from the backup without paying a ransom.
Security Awareness is Key: Phishing emails are a standard method for cryptoviral attacks. Educate yourself and your family about the signs of phishing attempts. Be cautious of suspicious emails, attachments, and links.
Layered Security for Maximum Protection: Consider combining security measures beyond antivirus software. These might include firewalls, anti-malware programs, and browser extensions that block malicious websites.
Software Updates: Patching the Gaps: Software updates often contain critical security patches that address vulnerabilities exploited by malware. Keeping your operating system, applications, and web browser updated is crucial.
Antivirus software offers valuable protection against known crypto-viruses, but it’s a single line of defence.
By implementing a layered security approach, maintaining backups, and practising safe computing habits, you can significantly reduce your risk of falling victim to cryptoviral extortion.
Cryptoviral extortion is a form of cybercrime that involves encrypting a victim’s data with a strong cypher and demanding a ransom payment to decrypt it. Attackers use malicious software called ransomware or crypto-viruses to carry out this extortion.
What does cryptovirology do?
Cryptovirology is a field of computer security that studies the use of cryptographic techniques in malicious software, particularly ransomware. It analyzes how encryption is used to lock victim data and explores methods for detecting, preventing, and mitigating such threats.
Who created cryptovirology?
The concept of cryptovirology is not attributed to a single person. It emerged from the evolution of cryptography and malware. In 1996, Adam L. Young and Moti Yung presented a paper at a security conference that is considered the foundation of the field, referring to it as “cryptoviral extortion.”
What is the function of cryptovirology?
The function of cryptovirology is to understand how attackers leverage cryptography in malware. By understanding these techniques, researchers can develop methods to:
Improve detection of ransomware through signature analysis or behavioural patterns.
Design algorithms to potentially decrypt files even without the decryption key.
Develop preventative measures to make systems more resistant to cryptoviral attacks.
What is the triple extortion scheme?
The triple extortion scheme is a variation of cryptoviral extortion where attackers encrypt a victim’s data and steal it. They then threaten to publish the stolen data publicly if the ransom is unpaid. This adds another layer of pressure on the victim, as a data leak could have severe legal or reputational consequences.
Wrapping UpÂ
Cryptoviral extortion is another ransomware attack that has continually invaded the cybersphere.
Since cryptovirus constantly evolve to evade advanced antivirus features, you should apply the above-listed preventive measures to keep your system safe.
In this post, we will show you how to configure web browser(s) with proxy information.
Configuring your web browser with proxy information isn’t as difficult as it may seem. The different methods involved depend on the web browser hosting the configuration.
However, the most important thing is that you should acquire your proxy information before configuring your web browser. Your proxy information includes your IP Address and Port Number.
The type of web browser plays a role in the configuration process. Hence, let’s look at the popular web browsers and how we can configure them with proxy information.
The internet offers a vast ocean of information, but sometimes you might want to navigate it with a bit more anonymity or access geo-restricted content.
Proxy servers act as intermediaries between your device and the websites you visit, potentially offering benefits like enhanced privacy security and bypassing regional restrictions.
This guide equips you with the knowledge to configure popular web browsers to utilize proxy servers, transforming you into a web-surfing secret agent.
Table of Contents
Understanding Proxies: A Gateway to New Possibilities
A proxy server acts as a middleman between your device and the internet. When you connect to a website using a proxy, your request first goes to the proxy server, which then forwards it to the website on your behalf.
The website sees the proxy server’s IP address instead of your own, potentially offering some level of anonymity.
Additionally, some proxies offer features like:
Content Filtering:Â These proxies can block access to certain websites or types of content.
Enhanced Security: Some proxies encrypt your traffic, adding an extra layer of security.
Geo-restriction Bypassing:Â Certain proxies allow you to access websites that might be restricted in your region.
Types of Proxies: Choosing the Right Tool for the Job
There are different types of proxies, each with its advantages and limitations:
Transparent Proxy (Least Secure): These proxies forward your requests without hiding your IP address. They offer minimal anonymity but might be useful for basic content filtering.
HTTP Proxy (Moderate Security): These proxies are more common and hide your IP address from the website you’re visiting. However, they don’t encrypt your traffic.
SOCKS Proxy (More Secure):Â These proxies offer better security than HTTP proxies by potentially encrypting all traffic passing through them.
High Anonymity Proxy (Most Secure): These proxies offer the highest level of anonymity by frequently changing their IP addresses. However, they can be slower due to the extra routing involved.
Important Note: Using proxies for malicious purposes is illegal. Always ensure you have permission to access any geo-restricted content.
Test the Proxy: Once you’ve configured the proxy settings, visit a website like WhatIsMyIP to verify that the proxy has masked your IP address.
Proxy Exceptions:Â You might want to configure exceptions for specific websites that don’t require a proxy or might not work well with it. This can be done within the browser’s proxy settings.
Turning off the Proxy: When you don’t need the proxy anymore, you can easily turn it off by following the same steps mentioned above and unchecking the relevant options.
Disclaimer:
Using a proxy server might slow down your internet connection due to the additional routing involved.
Free proxy servers can be unreliable and might have security vulnerabilities. Consider using a reputable paid proxy service if security and performance are critical.
