The malicious program named Cyber is malware from the ransomware type. Upon being executed on a breached system, it immediately initiates an encryption process for all the files on the device and appends their original filenames with a '.Cyber' extension. For instance, a file with an initial name of '1.doc' would now appear as '1.doc.Cyber' after being encrypted. Similarly, '2.pdf' would become '2.pdf.Cyber", and so on. Cybersecurity researchers point out that the Cyber Ransomware threat is based on the Chaos malware strain.

In addition to the file encryption, the Cyber Ransomware also changes the desktop wallpaper and generates a ransom note named 'read_it.txt.' The ransom note contains instructions for the victims, with the cybercriminals responsible for ransomware attacks usually demanding payment in exchange for the decryption key to unlock the encrypted files.

Cyber Ransomware Can Render Numerous Filetypes Inaccessible via Encryption

The ransomware note indicates that the victim's important files, such as databases, documents, and photos, have been encrypted and can only be decrypted by paying a ransom in Bitcoin cryptocurrency. The ransom amount is typically mentioned, and victims are given a way to test decryption on a limited number of files before they pay.

The note often contains contact information for the attackers or their representatives. However, sometimes the contact information may not be valid, and the victim may have difficulty communicating with the attackers. Additionally, the ransomware's wallpaper may display the same message and ransom amount but with different contact details.

In most ransomware attacks, decryption without the attackers' involvement is typically not possible. Even when victims pay the ransom, they may not receive the decryption keys or software necessary to recover their files. As a result, experts strongly advise against paying the ransom, even if the contact information is legitimate and the ransom amount seems affordable.

It is essential to remember that paying the ransom supports criminal activity and does not guarantee the recovery of the encrypted data. Victims should explore other options, such as restoring files from backups or seeking assistance from security experts.

Make Sure To Protect Your Devices and Data from Threats Like Cyber Ransomware

The best measures that users can implement to protect their devices and data from ransomware attacks involve a combination of proactive and reactive strategies.

First, users should be vigilant in their online activity and take steps to avoid falling victim to common ransomware infection vectors, such as phishing emails or malicious downloads. This includes using strong and unique passwords, regularly updating software and operating systems, and being cautious of suspicious emails or links.

Second, users should implement security measures, such as using reputable anti-malware software and enabling firewalls to block unauthorized access to their devices. They should also consider using endpoint detection and response (EDR) tools, which can help detect and respond to ransomware attacks in real time.

Third, users should regularly back up their important data to an external source, such as a cloud service or an external hard drive. This can help ensure that even if their device is infected with ransomware, they can still access their data without paying the ransom.

Fourth, in the event of a ransomware attack, users should avoid paying the ransom as it may not guarantee the safe recovery of their data and may also encourage further criminal activity. Instead, they should seek professional help from security experts and consider reporting the attack to law enforcement.

Finally, users should stay informed about the latest ransomware threats and evolving attack techniques to remain aware and prepared to protect themselves against potential attacks.
