  • AWS CloudWatch Alarm Deletion source medium: Detects the deletion of one or more Amazon CloudWatch alarms using the "DeleteAlarms" API. CloudWatch alarms are critical for monitoring metrics and triggering alerts when thresholds are exceeded. An adversary may delete alarms to impair visibility, silence alerts, and evade detection following malicious activity. This behavior may occur during post-exploitation or cleanup phases to remove traces of compromise or disable automated responses.
