Hazard Ransomware is a MedusaLocker Variant

While going over malware samples, an analysis uncovered a ransomware variant known as Hazard, which is part of the MedusaLocker family. The purpose of this malicious software is to scramble files on the compromised system and modify their filenames by appending the ".hazard18" extension (the number in the extension can be different).

For instance, when Hazard encrypts files, it alters their names, turning "1.jpg" into "1.jpg.hazard" and "2.png" into "2.png.hazard." Additionally, it leaves a ransom note titled "HOW_TO_BACK_FILES.html."

The ransom note conveys to the victim that their files have been encrypted using RSA and AES encryption. It cautions against attempting to recover the files using third-party software, as this could lead to permanent data corruption. The note emphasizes that only the ransomware operators can provide a solution and implies the possibility of exposing confidential data if the ransom is left unpaid.

The note also provides contact information, including a Tor URL and email addresses (ithelp02@securitymy.name and ithelp02@yousheltered.com). It warns that the ransom amount will increase if the victim fails to contact the operators within 72 hours.
