Punisher Virus Removal Guide (+Decode .punisher files) – WannaCash Ransomware

Punisher – General Info

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

The message given by Punisher text file requesting the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the WannaCash type. It literally mentions that the information is encrypted which the only way to restore it is to use a an unique decryption key. Sadly, this is definitely true. The kind of cryptography mechanism applied by Punisher is still not appropriately examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely distinct. It is impossible to restore the files without the key available.

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

However, irrespective of the asked for amount, people must stay away from paying the ransom virus. Cyber frauds are not fair, so they tend to completely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom typically does not give any positive result and people simply lose their money for absolutely nothing.

We strongly recommend 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 Punisher ransomware and to recover the information data totally free. Therefore, the only best decision is to recover the lost data from the available backup.
