What it detects
This rule flags AdFind launched with command-line arguments commonly associated with Active Directory discovery and related reconnaissance. Such usage matters because attackers may query domain information (including domain admin-related targets and computer/domain enumeration flags) to map environments before further exploitation. It relies on Windows process creation telemetry and matching specific AdFind command-line substrings.
