DEMS Ransomware

Part of the Matrix Ransomware family, the DEMS Ransowmare is a potent threat that can take over compromised systems and render the data stored there inaccessible. The DEMS Ransomware achieves this by initiating an encryption process with a combination of strong cryptographic algorithms. The attackers then extort their victims for money while promising to provide them with the decryption key needed to restore the affected files.

DEMS Ransomware's Details

The behavior of the DEMS Ransomware is mostly consistent with that of other Matrix variants. It encrypts targeted file types and then changes the original names of the files completely. The new names follow the pattern [Email of the Attackers].[Random String].[New Extension]. The email used by the threat in the file names is 'Deus69@criptext.com,' while the new extension is '.DEMS.' When all target files are encrypted, the DEMS Ransomware delivers a ransom-demanding message to the breached system. The ransom note is contained inside a file named 'DEMS_README.rtf' that is dropped onto the desktop.

DEMS Ransomware's Demands

The ransom note reveals that the threat uses a combination of the AES_256 and RSA-2048 algorithms for its encryption. To get the necessary decryption codes, victims must pay a ransom. The cybercriminals put further pressure on their victims by stating that they have managed to steal sensitive data from the compromised devices. The obtained information will be released to the public on the Dark Net if 72 hours pass without any communication.

To make sure that their message goes through, DEMS Ransomware's victims are instructed to send a message to all three of the emails mentioned in the note. The addresses are - Deus69@criptext.com, Deus69@cock.li, and Deus69@tuta.io. In addition, the hackers also can be reached via the TOX chat. Affected users also are allowed to send between 3 and 5 encrypted files to be unlocked for free. The files shouldn't be too big and must not contain any important information.

The full text of DEMS Ransomware's message is:
