+This rule detects an unusual volume of Kubernetes API get requests against multiple distinct Secret objects from the same client 
+fingerprint (user, source IP, and user agent) within a defined lookback window. This can indicate credential access or in-cluster
+reconnaissance, where a user or token is used to enumerate and retrieve sensitive data such as service account tokens, registry 
+credentials, TLS material, or application configuration. Failed get requests are also included, as they may reveal RBAC boundaries, 
+confirm the existence of targeted secrets, or reflect automated probing activity.

+### Investigating Kubernetes Rapid Secret GET Activity Against Multiple Objects
+
+This rule surfaces clusters of `get` operations on the `secrets` API where the same identity and client path
+(`user.name`, `source.ip`, `user_agent.original`) touch several different secret names within the rule lookback window.
+**Allowed and denied** outcomes are included: successful reads may indicate harvesting; repeated **forbidden** or
+**unauthorized** responses can still signal reconnaissance, RBAC probing, or scripted spray against secret names that
+exist in the cluster.
+
+### Investigation steps
+
+- Inspect `Esql.outcome` for a mix of allow vs deny and whether failures cluster on sensitive namespaces.
+- Map the identity to RBAC and namespace scope; review `Esql.secrets_names` and `Esql.namespaces` for high-value
+  targets (tokens, registry credentials, TLS bundles, application secrets).
+- Pivot on the same `source.ip` and user for follow-on API activity (exec, pod create, role changes, broad `list` on secrets).
+- Validate against expected automation (CI, GitOps, backup, in-cluster controllers) before treating as malicious.
+
+### False positives
+
+- Startup, Helm, or controllers may legitimately touch many secrets in one window; tune by user, namespace, or IP
+  allowlists when baselined.
