Brusaf Virus Removal Guide (+Decrypt .brusaf files) – DJVU Ransomware

Brusaf Virus Ransomware

The Brusaf stands for a ransomware-type infection. Initially, it was revealed by Michael Gillespie. The virus comes from the DJVU ransomware family. Brusaf was elaborated specifically to encrypt all major file types. When the file is encrypted people are not able to use them. Brusaf adds the “.brusaf” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Brusaf, will be renamed into “myphoto.jpg.brusaf. As quickly as the encryption is finished, Brusaf places a special text file (such as “_readme.txt“) into every folder containing the encrypted data.

The message given by Brusaf text file requesting for the ransom is definitely the like the statements given by other ransomware representatives coming from the DJVU clan. It literally points out that the information is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism used by Brusaf is still not properly examined. Still, it is definitely particular 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!”, Brusaf message:

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

Another trick of Brusaf is that the victims cannot access to the key. The key is kept on a specific server run by the frauds related to Brusaf ransomware. To get the key and recover the important information people have to pay the ransom, which amounts to $980. To get the payment details users are instructed to contact the frauds through e-mail or telegram. The alert likewise shows that the users require to contact the Brusaf developers within 72 hours after the encryption happened. The message says that doing so users will get a 50% discount, so the ransom amount will drop down to $490.

However, irrespective of the asked for amount, people should keep away from paying the ransom. Cyber frauds are unfair, so they tend to entirely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people simply lose their money for absolutely nothing.

We highly 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 Brusaf ransomware and to recover the data data for free. Hence, the just best decision is to recover the lost data from the available backup.
