Rugi Ransomware

Ransomware attacks continue to plague computer users worldwide, and one of the latest threats to emerge is the Rugi virus. This dangerous malware belongs to the STOP/DJVU ransomware family and primarily targets Windows systems. It encrypts valuable files and appends the .rugi extension, making them inaccessible to users. The cybercriminals behind the Rugi virus then demand a ransom payment in exchange for a decryption key.

What Is Rugi Virus?

The Rugi virus is a type of ransomware that uses the AES encryption algorithm to lock files on infected computers. Once files are encrypted, the virus adds the .rugi extension to the affected files. For example, a file named document.docx becomes document.docx.rugi.

After encrypting the files, the ransomware generates a ransom note named _readme.txt, which demands payment in exchange for the decryption tool. The attackers promise to decrypt one file for free as 'proof' and offer a 50% discount if contacted within 72 hours. However, paying the ransom does not guarantee file recovery and only funds future attacks.
