Detects the deletion of an Amazon GuardDuty detector. GuardDuty provides continuous monitoring for malicious or unauthorized activity across AWS accounts. Deleting the detector disables this visibility, stopping all threat detection and removing existing findings. Adversaries may delete GuardDuty detectors to impair security monitoring and evade detection during or after an intrusion. This rule identifies successful "DeleteDetector" API calls and can indicate a deliberate defense evasion attempt.
