When the encryption is accomplished, Jdyi puts its own distinct text file (_readme.txt) into all the folders that save the encrypted files.
The message stated by text file requesting for the random os very comparable to the alerts provided by other ransomware risks coming from the DJVU family. The warning essentially shows that the data has been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely real.
The technique to secure the files utilized by Jdyi is not totally researched. However, there is no doubt that each computer system owner may be provided a special decryption key, which is absolutely unique. It is extremely difficult to recover the data without the proper key in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Jdyi virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have launched the Jdyi infection into the world wide web. In order to obtain the key and restore the essential data, the users are told to contact 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 the people need to contact the Jdyi authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so the people will get a 50% discount, therefore, the ransom quantity falls to $490.
