Jaoy was developed for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is effectively achieved, the users are not able to get access to them. Jaoy ransomware adds its own “.jaoy” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Jaoy, will be titled as “price_list.xls.jaoy”. When the file encryption is achieved, Jaoy puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The message mentioned by document asking for the random os really similar to the alerts offered by other ransomware dangers 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 distinct standalone key. Regretfully, this statement is absolutely real.
The technique to encrypt the files utilized by Jaoy is not totally researched. Nevertheless, there is no doubt that each computer system owner might be provided a special decryption key, which is definitely special. It is incredibly hard to recuperate the information without the suitable key in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Jaoy 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 total control by the crooks who have introduced the Jaoy virus into the internet. In order to acquire the key and restore the important information, the users are told to get in touch with the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
The message also states that individuals need to call the Jaoy authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so individuals will get a 50% discount rate, therefore, the ransom amount drops down to $490.

Hence, paying ransom frequently does not lead to an effective healing. So, the users might just lose their money for nothing.

There are no applications that might split the Jaoy ransomware or bring back the data at no cost. For that reason, the only appropriate decision is to restore the information from possible backups (if available).
