Ranstop protects against Sorebrect fileless ransomware – TEMASOFT Lab Demo

Sorebrect case subject – fileless ransomware

This variant arrives as a text file with a name that tricks the users into opening it either downloaded from malicious websites or installed by other malware. It injects malicious code in the Service Host process (svchost.exe) to avoid antivirus detection and application control. The actual encryption is done from the svchost.exe process and it avoids some of the Windows system folders. The ransomware searches for common anti-malware software and attempts to stop the associated services.

    These types of ransomware are usually eluding antivirus detection, especially the zero-day variants, simply because they are using legitimate processes in which they inject malicious code via seemingly appropriate techniques. Use antivirus in conjunction with anti-ransomware technology for best protection.
