Remove yakuza Virus (+Decrypt .yakuza files)

yakuza – General Info

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

The message given by yakuza text file asking for the ransom is absolutely the same as the statements given by other ransomware representatives. It actually points out that the information is encrypted which the only way to bring back it is to use a an unique decryption key. Sadly, this is absolutely true. The sort of cryptography mechanism used by yakuza is still not properly examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is totally distinct. It is difficult to bring back the files without the key available.

Another trick of yakuza is that the victims cannot get to the key. The key is kept on a specific server run by the frauds related to yakuza ransomware. To get the key and recover the important info people need to pay the ransom.

Nonetheless, regardless of the requested amount, people must keep away from paying the ransom. Cyber frauds are not fair, 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 generally does not give any positive result and people just lose their money for absolutely nothing.

We highly encourage 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 yakuza ransomware and to recover the data data totally free. Therefore, the only best decision is to recover the lost information from the available backup.
