MRDC Ransomware

Infosec experts have detected a new ransomware threat. Tracked as the MRDC Ransomware, this new malware is capable of locking up numerous file types, rendering them inaccessible and unusable effectively. Victims will find themselves unable to open any documents, photos, archives, databases, PDFs, etc., stored on the breached devices. Analysis of MRDC Ransomware's code and behavior reveals that it is a variant from the Matrix Ransomware family. Although its capabilities are largely consistent with those of the previously observed Matrix variants, that it in no way diminishes the danger it poses.

MRDC renames the files it encrypts completely. The new names follow the pattern - [email address of the hackers].[random string].[new file extension]. The email address used by the threat is 'markusdoc88@criptext.com' while the extension is '.MRDC.' Upon reaching the end of its encryption process, the threat will drop a ransom note with instructions for its victims. The note is contained inside a newly generated file named 'MRDC_README.rtf.'

MRDC Ransomware's Demands

The ransom-demanding message doesn't reveal the exact sum that the hackers want to receive from their victims. However, it does state that during the ransomware attack, sensitive private information was collected and uploaded to a remote server. The hackers threaten to start leaking the collected information on the Dark Web if the victims take more than 72 hours to initiate communication.

To avoid this outcome, victims are told to send a message to all three of the email addresses provided in the ransom note. The emails are 'markusdoc88@criptext.com,' 'markusdoc88@yahoo.com' and 'markusdoc88@tutanota.com.' Alternatively, affected users can contact the cybercriminals via the TOX Chat.

MRDC Ransomware's victims are allowed to send between 3 and 5 files that will supposedly be decrypted for free. The files need to be relatively small and shouldn't contain any valuable information.

The entire ransom note delivered by the MRDC Ransomware is:
