Threat Database Ransomware Mmuz Ransomware

Mmuz Ransomware

Cybersecurity researchers have classified the Mmuz Ransomware threat as being another variant of the infamous STOP/Djvu malware family. Even though Mmuz may not be an entirely unique threat, users should not underestimate the damage it can cause. If successfully deployed, the threat will initiate a data-encryption routine on the device, and leave the vast majority of the files stored there, in an unusable state.

Victims also will discover that each locked file now has a new file extension - '.mmuz,' attached to its original name. A ransom note containing the demands of the attackers also will be dropped on the infected machine. The note will be delivered as a text file named '_readme.txt.'

Attacker's Demands

Mmuz Ransomware's note reveals that the cybercriminals demand to receive a ransom of $980 if they are to assist their victims in restoring the encrypted data. However, that initial amount of the ransom can be decreased by 50% with the only listed requirement being that victims contact the hackers during the first 72 hours of the attack. This can be achieved by sending a message to the two email addresses found in the note - '' and ',' or the cybercriminals' Telegram account. Of course, communicating with people responsible for the spread of ransomware threats is not without risks and users may want to avoid doing so.
