This rule monitors for suspicious process execution (e.g., cmd, powershell) spawned from PaperCut service processes (pc-app.exe, tomcat.exe) followed by a Domain Admin group membership change on the same device within a 30-minute window. This behavior is indicative of privilege escalation attempts following the exploitation of PaperCut vulnerabilities (CVE-2026-81578/CVE-2026-82078).
