What it detects
This rule flags antivirus detections whose signature matches common hacktool and attack tool names, including prefixes and specific indicator strings. Such matches are important because attackers may deploy offensive tooling that can lead to credential theft, persistence, and post-exploitation activity even if blocking occurs. It relies on antivirus alert telemetry that provides the detection signature value to evaluate prefix and substring conditions.
