Wnlu Virus Removal Guide (+Decrypt .wnlu files)

Wnlu – General Info

Wnlu is a harmful software application functioning as typical ransomware. Michael Gillespie, the widely known virus researcher, very first found this new name in the DJVU ransomware family.

Wnlu was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the encryption is successfully accomplished, the users are unable to get access to them. Wnlu virus includes its own “.wnlu” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Wnlu, will be entitled as “price_list.xls.wnlu”. As soon as the encryption is achieved, Wnlu puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.

The message stated by document requesting for the random os really comparable to the notifications provided by other ransomware hazards coming from the DJVU family. The warning generally indicates that the information has been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely true.

The method to secure the files utilized by Wnlu is not totally looked into. Nevertheless, there is no doubt that each computer owner might be issued a special decryption key, which is definitely distinct. It is incredibly difficult to recuperate the data without the appropriate type in place.

One more peculiarity of the Wnlu ransomware is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have introduced the Wnlu infection into the world wide web.
