What is Jjtt Ransomware
Recently, experts have observed the epidemic of the virus Jjtt Ransomware (also known as STOP Ransomware or Djvu Ransomware). It is an encryption virus, that uses a strong AES-256 encryption algorithm to encrypt user files and makes them unavailable for use without a decryption key. Latest versions of this pest add .jjtt extensions to affected files. Jjtt Ransomware creates special text file, that is called “ransom note” and named _readme.txt. In this text file, malefactors provide contact details, overall information about encryption, and options for decryption. The virus copies it on the desktop and in the folders with encrypted files. Malefactors can be contacted via e-mails: firstname.lastname@example.org and email@example.com. Here is the text from such file:

Using anonymous TOR servers and cryptocurrency to receive ransom payments makes hackers almost invulnerable, however, due to their own mistakes, they get caught from time to time. The price of decryption of this ransomware is set to $980, but it can be reduced by half if paid within 72 hours. This is done to increase the conversion of users, who are ready to pay for the return of their files. Cybercriminals can even decrypt one file for free, to prove to you, that they will send a decryptor and it will work. We strongly advise not to pay any money to them, as there is no guarantee that such dubious personalities will keep promises. Mention also, that there is a special utility called STOP Djvu Decryptor, that can decrypt (or will be able to decrypt in the nearest future) files encrypted by Jjtt Ransomware for free. There are also certain alternative methods, that will help you recover some of your data. For example, file recovery software, using system features of Windows or backups (if the backup was set up before infection). Such ransomware threats were designed to prevent any attempts of recovery, but developers also make mistakes.

Jjtt Ransomware comes along with AZORult trojan, which was initially created to steal logins and passwords. The process of infection also looks like installing Windows updates, the malware shows a fake window, that mimics the update process.
It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. Jjtt Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. Can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers.
