MSSQL xp_cmdshell mofcomp.exe BMOF WMI Persistence via Temp-Staged File
Detects the compilation of a Managed Object Format (MOF) file using mofcomp.exe from the temporary directory of the MSSQL service account. This behavior is indicative of an attacker leveraging the xp_cmdshell procedure in MSSQL to deploy a malicious MOF file, which registers a WMI permanent event subscription to establish persistence or facilitate secondary payload execution.
