What it detects

This rule detects a Run key autostart entry whose value references svchost.exe located under a user AppData Roaming path. The Yashma ransomware established persistence through a Run key pointing at its dropped svchost.exe masquerade copy. This lets the ransomware survive reboots by abusing a trusted process name from an illegitimate location.
