Suspicious PPL Manipulation Through WerFaultSecure (via process_creation)
This rule detects potential misuse of WerFaultSecure.exe to dump Protected Process Light (PPL) processes like LSASS or to freeze security solutions (EDR/antivirus). This method is used by tools such as EDR-Freeze and WSASS to bypass PPL protections and access sensitive information or disable security software. Distinct command line patterns help identify the specific tool: - WSASS use usually shows: "WSASS.exe WerFaultSecure.exe [PID]" in ParentCommandLine - EDR-Freeze use usually shows: "EDR-Freeze_[version].exe [PID] [timeout]" in ParentCommandLine Legitimate debugging operations using WerFaultSecure are rare in production environments and should be investigated.
