status: stable
description: This rule identifies Windows Defender malware detection engine and antimalware platform events indicating malware or suspicious behavior and subsequent protection actions. Such detections matter because attackers often rely on persistence and execution of malicious content, and Defender telemetry provides high-signal evidence that defensive engines observed potentially unwanted activity. It relies on windefend logs with Event IDs 1006, 1015, 1116, and 1117, which correspond to detection and remediation-related engine activity.
