Once the file encryption is accomplished, Ptrz puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.
The alert stated by _readme.txt asking for the random os very comparable to the notifications provided by other ransomware threats 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 a special standalone key. Regretfully, this statement is absolutely real.
The method to encrypt the files used by Ptrz is not completely investigated. However, there is no doubt that each computer owner may be provided an unique decryption key, which is absolutely unique. It is very difficult to recover the information without the proper key in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Ptrz infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have actually introduced the Ptrz ransomware into the web. In order to obtain the key and bring back the crucial information, the users are told to contact the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.
The message likewise states that individuals need to get in touch with the Ptrz authors within 72 hours upon the moment of the data encryption. The alert indicates that by doing so individuals will obtain a 50% discount, therefore, the ransom quantity drops down to $490.
