Threat Database Ransomware Sunjn Ransomware

Sunjn Ransomware

Sunjn is ransomware that targets its victims by encrypting their files and altering the filenames. The altered filenames include a unique identifier assigned to each victim, the email address of the cybercriminals, and a '.sunjn' extension. For instance, if a file were named "1.jpg" initially, after encryption, it would appear as '1.png.[ID STRING].(" Once the encryption process is complete, the ransomware leaves a ransom-demanding message in the form of a file called "Decryption-guide.txt" on the desktop of the breached device.

Sunjn Ransomware's Demands

Sunjn's ransom-demanding message informs victims that their files have been encrypted and locked and are now inaccessible. The message warns against attempting to modify or rename the encrypted files, using third-party decryption tools, or reinstalling the operating system, as these actions could result in permanent data loss. The note includes instructions on how to contact the attackers by email ('' and ''), who are the only ones capable of providing the necessary decryption keys.

In the case of ransomware attacks, it is typically not possible to restore the affected data without the intervention of the cybercriminals responsible for the attack. Attempts to decrypt the files by other means are often unsuccessful and could damage the files.

Paying Cybercriminals is not Recommended

There are several reasons why paying any amount of money or meeting any of the demands made by cybercriminals should be avoided. First, receiving payments from their victims will further encourage the attackers to continue with their criminal activity. This may mean future ransomware attacks that could cause even bigger financial losses.

The second reason is that even if victims pay the asked amount, there is still no guarantee of successful decryption. The attackers may not provide the decryption keys or may provide keys that don't work, leaving the victims with no way to access their encrypted files and no means of recovery.
