What it detects

This rule detects WailingCrab persistence that runs a renamed copy of printfilterpipelinesvc.exe from a user directory via a registry Run key. The legitimate binary lives under System32, so execution from another location signals masquerading. This provides the malware autostart under a trusted-looking name.
