Description
Adversaries who land credentials in a GKE cluster—or abuse an over-privileged token, often map the environment before exfiltration or privilege escalation. A practical first pass is to learn where workloads run, how the cluster is partitioned, and what RBAC exists at namespace vs cluster scope. Rapid get/list traffic across many distinct API resource kinds that answer those questions (namespaces, workloads, roles, cluster-wide roles) is a common setup and orientation pattern for both interactive attackers and automated recon scripts. This rule highlights that cross-resource burst from a single client fingerprint within a one-minute bucket when both cluster-layout and RBAC resource kinds are touched, so analysts can separate routine automation from potential discovery ahead of follow-on actions.
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.
Detection requirements
- Platform
- Containers
The rule states no platform. This is derived from the ATT&CK technique it maps to.
Known benign triggers
- GitOps controllers and cluster scanners can still match if not covered by built-in exclusions; baseline approved service accounts after review.
- Platform operators, installers, or runbooks that reconcile RBAC and workload state may span these resource types in a short window; tune by identity, source IP, or user agent when documented.
MITRE ATT&CK mappings
0 exclusive techniques.This is coverage no other published rule has; it is not this rule's total technique count.
