Remove Bukyak Virus (+Decrypt .bukyak files) – Aurora Ransomware

Bukyak Virus Ransomware

The Bukyak mean a ransomware-type infection. The virus comes from the Aurora ransomware family. Bukyak was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Bukyak adds the “.bukyak” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Bukyak, will be renamed into “myphoto.jpg.bukyak“. As quickly as the encryption is finished, Bukyak places a special text file into every folder containing the encrypted data.

The message given by Bukyak text file requesting the ransom is definitely the like the statements given by other ransomware virus representatives coming from the Aurora type. It actually discusses 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 kind of cryptography mechanism used by Bukyak is still not properly examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is totally unique. It is difficult to bring back the files without the key available.

Another technique of Bukyak is that the victims cannot gain access to the key. The key is saved on a particular server run by the frauds related to Bukyak ransomware. To get the key and recover the important info people need to pay the ransom.

Nonetheless, irrespective of the requested amount, people should stay away from paying the ransom. Cyber frauds are not fair, so they tend to completely ignore 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 outcome and people just waste their money for nothing.

We strongly advise 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 Bukyak ransomware and to recover the information data for free. Thus, the just best decision is to recover the lost information from the available backup.
