Remove BGUU Virus (+Decrypt .BGUU files) – Hidden Tear Ransomware

BGUU – Ransomware

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

The message given by BGUU text file requesting the ransom is definitely the like the statements given by other ransomware representatives belonging to the Hidden Tear clan. It literally mentions that the info is encrypted and that the only way to bring back it is to use a an unique decryption key. Regretfully, this is absolutely true. The kind of cryptography mechanism applied by BGUU is still not correctly examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.

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

Nonetheless, irrespective of the asked for amount, people need to stay away from paying the ransom. Cyber frauds are unfair, so they tend to totally ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive result and people just lose their money for absolutely nothing.

We strongly encourage 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 BGUU ransomware and to recover the information data free of charge. Thus, the only best decision is to recover the lost data from the available backup.
