What it detects

This rule detects the Vertex AI per-product service agent enumerating Artifact Registry packages, a cloud discovery behavior demonstrated in the Double Agents research against GCP Vertex AI. Enumeration of container and package registries by the AI platform identity reflects abuse of the P4SA credential to map resources beyond its intended scope.
