Pyas Virus Removal Guide (+Decrypt .pyas files)

Pyas – Ransomware

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

Pyas was developed for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is effectively accomplished, the users are not able to get access to them. Pyas virus adds its own “.pyas” to all the encrypted files. For example, the file “price_list.xls”, as soon as crypted by Pyas, will be titled as “price_list.xls.pyas”. As soon as the encryption is achieved, Pyas puts its own special text document (_readme.txt) into all the folders that store the encrypted files.

The alert specified by _readme.txt requesting the random os really comparable to the notices given by other ransomware hazards coming from the DJVU family. The warning basically shows that the information has been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The approach to encrypt the files utilized by Pyas is not totally investigated. However, there is no doubt that each computer owner may be issued an unique decryption key, which is definitely special. It is very tough to recover the data without the appropriate type in place.

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

One more peculiarity of the Pyas infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the criminals who have released the Pyas infection into the world wide web. In order to acquire the key and bring back the important information, the users are informed to contact the scams via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that individuals should get in touch with the Pyas authors within 72 hours upon the moment of the data encryption. The alert shows that by doing so the people will acquire a 50% discount rate, for that reason, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we highly recommend that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom often does not result in an effective healing. So, the users might merely lose their money for absolutely nothing.

Similarly, we prompt you not to contact the frauds as they advise. Do not move loan into their wallets. There are no applications that might split the Pyas virus or restore the information for free. Therefore, the only right choice is to restore the data from possible backups (if available).
