What it detects

This rule flags process executions on Windows where command-line parameters indicate querying the Windows event log using built-in utilities such as wevtutil.exe, wmic.exe, or PowerShell event log cmdlets. Attackers often query event logs to locate sensitive information that may be present in logged events, such as credentials, usernames, or other identifying data. It relies on process creation telemetry including the executable path/name, original file name, and command-line contents.
