This rule detects potential privilege escalation exploiting a dangling COM object registration (CLSID {E9F83CF2-E0C0-4CA7-AF01-E90C70BEF496}). It monitors for a non-SYSTEM user creating a DLL within the 'CrossDevice' ProgramData folder, followed by a scheduled task trigger, and subsequently detects 'dllhost.exe' running as SYSTEM loading that specific malicious DLL, indicating successful execution of unauthorized code with elevated privileges.
Detects the creation of a DLL file within the 'ProgramData\CrossDevice\' directory. This path is associated with a dangling COM InprocServer32 registration and does not exist by default. The creation of files in this location by non-privileged processes is indicative of staging malicious DLLs for exploitation of COM-based privilege escalation chains, specifically CVE-2026-66804 and CVE-2026-50343.
Detects the dllhost.exe process, running with SYSTEM privileges, loading a dynamic link library (DLL) from a user-writable path within the ProgramData directory. This behavior is consistent with the abuse of COM marshaling, specifically exploiting dangling CLSID entries to force a privileged COM host process to unmarshal and load an attacker-controlled DLL.
