Sato Virus Removal Guide (+Decrypt .sato files)

Sato Virus – Details

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

Sato was developed for the sole function to encrypt all popular file types. Logically, as soon as the file encryption is successfully achieved, the users are not able to get access to them. Sato virus includes its own “.sato” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Sato, will be entitled as “price_list.xls.sato”. When the file encryption is achieved, Sato puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by _readme.txt requesting for the random os really comparable to the alerts offered by other ransomware hazards coming from the DJVU family. The warning generally indicates that the data has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.

The technique to encrypt the files utilized by Sato is not completely investigated. However, there is no doubt that each computer system owner may be provided an unique decryption key, which is definitely distinct. It is incredibly difficult to recover the information without the suitable type in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

One more peculiarity of the Sato virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have launched the Sato virus into the web. In order to obtain the key and bring back the crucial data, the users are told to contact the frauds via email or by telegram and to pay the ransom in the quantity of $980.

The message also says that individuals need to call the Sato authors within 72 hours upon the moment of the information file encryption. The alert suggests that by doing so the people will obtain a 50% discount, therefore, the ransom amount falls to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no warranty that these online crooks will keep their pledges, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts.

There are no applications that might split the Sato ransomware or bring back the data at no cost. For that reason, the only correct choice is to restore the data from possible backups (if offered).
