Description
Detects the deletion of an Amazon CloudWatch Log Group using the "DeleteLogGroup" API. CloudWatch log groups store operational and security logs for AWS services and custom applications. Deleting a log group permanently removes all associated log streams and historical log data, which can eliminate forensic evidence and disrupt security monitoring pipelines. Adversaries may delete log groups to conceal malicious activity, disable log forwarding, or impede incident response.
Detection logic
Its licence does not clear it for publishing here
Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

Known benign triggers
- CloudWatch log group deletions may occur during normal maintenance or infrastructure re-deployments, especially in environments managed by IaC tools (e.g., Terraform, CloudFormation, CDK). Automation pipelines may recreate log groups as part of expected workflows. Verify that the identity, user agent, and source IP match approved administrative or automation activity. If deletions are routine for specific automation roles or CI/CD hosts, consider adding scoped exceptions.
