DoppelPaymer – General Info

The DoppelPaymer mean a ransomware-type infection. The infection comes from the BitPaymer ransomware family. DoppelPaymer was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are not able to use them. DoppelPaymer adds the “.locked” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by DoppelPaymer, will be renamed into “myphoto.jpg.locked“. As soon as the encryption is finished, DoppelPaymer places a special text file into every folder containing the encrypted data.

The message given by DoppelPaymer text file requesting the ransom is absolutely the same as the statements given by other ransomware representatives coming from the BitPaymer clan. It literally points out that the information is encrypted which the only way to bring back it is to use a a special decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism used by DoppelPaymer is still not properly examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is absolutely unique. It is impossible to bring back the files without the key available.

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

Nevertheless, regardless of the requested quantity, people must keep away from paying the ransom virus. Cyber frauds are unfair, so they tend to completely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom normally does not give any positive outcome and people just lose their money for absolutely nothing.

We highly advise 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 DoppelPaymer ransomware and to recover the information data totally free.
