What it detects

This rule detects a Google Cloud Build default service account invoking storage bucket or object deletion which was abused to destroy data by triggering builds that ran attacker controlled steps. Destructive storage operations originating from a cloudbuild or compute default service account rather than a human principal indicate potential data destruction through the Cloud Build pipeline.
