What it detects

This rule flags Bitbucket audit events where a repository is added to the secret scanning exempt list. Attackers may use exemptions to avoid automated detection of exposed credentials in repositories. The detection relies on Bitbucket audit log telemetry identifying the repository category and the specific action "Secret scanning exempt repository added".
