Madek Virus Removal Guide (+Decrypt .madek files) – DJVU Ransomware

Madek Virus Ransomware

The Madek mean a ransomware-type infection. Initially, it was revealed by Michael Gillespie. The infection comes from the DJVU ransomware family. Madek was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Madek adds the “.madek” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Madek, will be renamed into “myphoto.jpg.madek. As soon as the encryption is finished, Madek places a special text file (such as “_readme.txt“) into every folder containing the encrypted data.

The message given by Madek text file asking for the ransom is definitely the same as the statements given by other ransomware virus representatives belonging to the DJVU family. It literally discusses that the information is encrypted and that the only way to bring back it is to use a a special decryption key. Regretfully, this is definitely true. The sort of cryptography mechanism applied by Madek is still not appropriately examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is totally distinct. It is impossible to restore the files without the key available.

“Don’t worry, you can return all your files!”, Madek message:

Don't worry, you can return all your files! virus

Another trick of Madek is that the victims cannot get to the key. The key is saved on a particular server run by the frauds connected with Madek ransomware. To get the key and recover the important info people have to pay the ransom, which totals up to $980. To obtain the payment details users are instructed to contact the frauds through email or telegram. The alert likewise shows that the users need to contact the Madek developers within 72 hours after the encryption took place. The message says that doing so users will get a 50% discount, so the ransom amount will fall to $490.

Nonetheless, irrespective of the asked for quantity, people must stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to entirely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive result and people just waste their money for absolutely nothing.

We highly encourage that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Madek ransomware and to recover the information data for free. Hence, the only right decision is to recover the lost data from the available backup.
