Dungeon Virus – Details

The Dungeon mean a ransomware-type infection. The infection comes from the Xorist ransomware family. Dungeon was elaborated particularly to encrypt all major file types. Once the file is encrypted people are not able to use them. Dungeon adds the “.([dungeon]-0_0)” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Dungeon, will be renamed into “myphoto.jpg.([dungeon]-0_0)“. As soon as the encryption is finished, Dungeon places a special text file into every folder containing the encrypted data.

The message given by Dungeon text file requesting for the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Xorist type. It literally points out that the information is encrypted and that the only way to bring back it is to use a a special decryption key. Unfortunately, this is definitely true. The type of cryptography mechanism applied by Dungeon is still not properly examined. Still, it is definitely certain that each victim might be given the specific decryption key, which is completely distinct. It is difficult to restore the files without the key available.

Another technique of Dungeon is that the victims cannot get to the key. The key is kept on a specific server run by the frauds connected with Dungeon ransomware. To get the key and recover the important info people need to pay the ransom.

This is why paying the ransom typically does not give any positive result and people just waste their money for nothing.

We strongly encourage 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 Dungeon ransomware and to recover the data data free of charge.
