Jjtt Virus – Details
Jjtt is a malicious software functioning as common ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.
Jjtt was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the file encryption is effectively achieved, the users are unable to get access to them. Jjtt ransomware adds its own “.jjtt” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Jjtt, will be titled as “price_list.xls.jjtt”. As soon as the file encryption is accomplished, Jjtt puts its own special text file (_readme.txt) into all the folders that store the encrypted files.
The message stated by document asking for the random os really comparable to the notifications offered by other ransomware dangers belonging to the DJVU family. The warning essentially shows that the files have been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.
The method to encrypt the files utilized by Jjtt is not entirely looked into. Nevertheless, there is no doubt that each computer system owner may be issued a special decryption key, which is absolutely special. It is very difficult to recover the information without the suitable key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Jjtt ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the criminals who have launched the Jjtt infection into the world wide web. In order to get the key and bring back the important data, the users are told to connect with 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 get in touch with the Jjtt authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so individuals will obtain a 50% discount, therefore, the ransom amount drops down to $490.
