Wsuu Virus Removal Guide (+Decrypt .wsuu files)

Wsuu Virus – Details

Wsuu is a destructive software functioning as typical ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.

Wsuu was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully achieved, the users are unable to get access to them. Wsuu virus includes its own “.wsuu” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Wsuu, will be titled as “price_list.xls.wsuu”. When the file encryption is achieved, Wsuu puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by _readme.txt requesting for the random os very comparable to the alerts given by other ransomware risks belonging to the DJVU family. The warning essentially indicates that the information has been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.

The method to secure the files utilized by Wsuu is not totally investigated. However, there is no doubt that each computer owner might be provided a special decryption key, which is absolutely special. It is very hard to recover the information without the proper key in place.

“Don’t worry, you can return all your files!”, from text file message:

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

One more peculiarity of the Wsuu infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have released the Wsuu infection into the web. In order to obtain the key and bring back the crucial data, the users are informed to connect with the frauds through e-mail or by telegram and to pay the ransom in the amount of $980.

The message also says that individuals need to get in touch with the Wsuu authors within 72 hours upon the moment of the data encryption. The alert indicates that by doing so individuals will acquire a 50% discount, therefore, the ransom amount falls to $490.

No matter what the amount of the ransom is, we strongly recommend that you do not pay the ransom. There is no warranty that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom frequently does not result in a successful recovery. So, the users might just lose their money for nothing.

Similarly, we prompt you not to get in touch with the scams as they advise. Do not move money into their wallets. There are no applications that could break the Wsuu virus or restore the information at no cost. For that reason, the only right decision is to restore the data from possible backups (if available).
