Оne of the distinguishing features of developers of STOP Ransomware is using “flat” pricing. Since the early versions, it demands $980 fee for decryption (or $490 if paid in 72 hours). Unlike, in other types of ransomware, where malefactors extort thousands of dollars, this price seems affordable. However, lately, hackers do not keep promises and do not send any decryption keys. Probably, they are afraid that releasing keys will fasten the decryption process for security experts. That is why do not rely on paying the ransom and better try all possible technical methods to restore your files. The first step will be of course the removal of actual virus files and protecting your computer. Then, we would recommend trying available decryption tools, especially STOP Djvu Decryptor from EmsiSoft. Then, all standard Windows features for information restoration are worth trying.

How STOP Ransomware infected your PC
STOP Ransomware victims most often receive it bundled with pirated and free software. The malware not only encrypts user files, but also installs malicious browser extensions, clickers, and other unwanted programs. In early 2019, experts reported that one of the STOP versions distributes the Azorult Trojan, which can steal user information. Virus modifies “hosts” file to block Windows updates, downloading antivirus programs, and visiting sites related to security news or offering security solutions. 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. STOP Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. It can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged and infected installers. Virus assigns certain ID with the victims, that is used to name those files and supposedly to send decryption key. Great tools to protect against STOP Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.
