Cyb Ransomware Will Encrypt Files on Your System
During our routine examination of newly submitted malware samples, our research team made an important discovery: the emergence of Cyb, another malicious program associated with the VoidCrypt ransomware family.
Upon running a sample of Cyb on our testing system, we observed that it immediately initiated the encryption process on various files, modifying their names by adding a ".cyb" extension. For instance, a file originally named "1.jpg" would become "1.jpg.cyb," while "2.png" would transform into "2.png.cyb," and so on. Once the encryption was completed, Cyb proceeded to generate a ransom note named "Dectryption-guide.txt."
The ransom note delivered by Cyb notifies the victims that their files have been securely encrypted. In order to recover their data, the note instructs them to establish communication with the cybercriminals. The message concludes with strong warnings against renaming or modifying the encrypted files, using third-party decryption tools, or attempting to reinstall the operating system, as such actions could lead to irreversible data loss.
Cyb Ransom Note Lists no Ransom
The full text of the Cyb ransom note reads as follows:
Your Files Are Has Been Locked
Your Files Has Been Encrypted with cryptography Algorithm
If You Need Your Files And They are Important to You, Dont be shy Send Me an Email

How Can You Protect Your Files from Ransomware Like Cyb?
Protecting your files from ransomware like Cyb requires implementing various proactive measures. Here are some effective steps to safeguard your data:
- Keep Software Updated: Regularly update your operating system, antivirus software, and all applications to ensure you have the latest security patches and bug fixes. Vulnerabilities in outdated software can be exploited by ransomware, so staying up to date is crucial.
- Be Cautious of Email Attachments and Links: Exercise caution when opening email attachments or clicking on links, especially if they are from unknown or suspicious sources. Verify the sender's identity and scan attachments with antivirus software before opening them.
- Backup Your Files: Regularly back up your important files to an external storage device or a reliable cloud backup service. Ensure your backups are not directly accessible from your computer or network to prevent them from being compromised by ransomware.
- Use Robust Security Software: Install reputable antivirus and anti-malware software on your system. Keep it updated and perform regular scans to detect and remove any potential threats, including ransomware.
- Exercise Safe Internet Practices: Avoid visiting suspicious websites, downloading files from untrusted sources, or engaging in risky online behavior. Be cautious of pop-up ads and only download software from official websites.
- Restrict User Privileges: Limit user privileges on your system. Avoid granting administrative rights to everyday user accounts. This way, even if a user's account gets compromised, the ransomware's ability to make system-wide changes will be limited.
- Enable File Extensions: Configure your system to display file extensions so that you can easily identify suspicious file types. Ransomware often disguises malicious files by using double file extensions (e.g., .pdf.exe).
By following these preventive measures and adopting a proactive approach to cybersecurity, you can significantly reduce the risk of falling victim to ransomware like Cyb and protect your valuable files.
