Remove MDEN Virus (+Decrypt .[SmartDen@protonmail.com].MDEN\” files) – Matrix Ransomware

MDEN – General Info

The MDEN stands for a ransomware-type infection. The virus comes from the Matrix ransomware family. MDEN was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are not able to use them. MDEN adds the “.[SmartDen@protonmail.com].MDEN\”” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by MDEN, will be renamed into “myphoto.jpg.[SmartDen@protonmail.com].MDEN\”“. As soon as the encryption is completed, MDEN places a special text file into every folder containing the encrypted data.

The message given by MDEN text file asking for the ransom is definitely the same as the statements given by other ransomware representatives belonging to the Matrix type. It actually discusses that the information is encrypted and that the only way to restore it is to use a a distinct decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism used by MDEN is still not appropriately examined. Still, it is definitely certain that each victim might be given the specific decryption key, which is totally unique. It is impossible to bring back the files without the key available.

Another technique of MDEN is that the victims cannot access to the key. The key is saved on a particular server run by the frauds associated with MDEN ransomware. To get the key and recover the important information people have to pay the ransom.

Nonetheless, irrespective of the requested quantity, people must stay away from paying the ransom. Cyber frauds are not fair, so they tend to totally disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people simply lose their money for absolutely nothing.

We strongly recommend that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack MDEN ransomware and to recover the data data free of charge. Thus, the just right decision is to recover the lost information from the available backup.
