What is STOP Ransomware

One of the main computer threats today is ransomware. Those are devastating computer viruses, that encrypt user’s files using various cryptographic algorithms and extort ransom money for the decryption key. It is especially sensitive for users, as it attacks either personal files such as videos, photos, music, or business data such as MS Office file formats, e-mails, databases. Such files can be crucial for business operation or extremely important personally as part of family memory. Malefactors can demand from several hundred to several thousand dollars as a ransom. STOP Ransomware is officially most wide-spread and therefore most dangerous ransomware threat. There’ve been more, than 230 versions of this virus in 3 years. Each variation infects thousands of computers, and there are millions of victims of this nasty malware.

How STOP Ransomware infected your PC

Malicious software created using the STOP virus gets four files when it enters a computer. One of them provokes the appearance of a fake message about Windows system updates. In this way, it lulls the user’s alertness. Cybercriminals do not name the cost of decryption, but promise to make a discount if the user in the near future turns to them for help.

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.
