* [New] AWS Lateral Movement from Kubernetes SA via AssumeRoleWithWebIdentity
Detects when credentials issued through `AssumeRoleWithWebIdentity` for a Kubernetes service account identity are later used for several distinct AWS control-plane actions on the same session access key. Workloads that use EKS IAM Roles for Service Accounts routinely exchange a projected service-account token for short-lived IAM credentials; this rule highlights sessions where that exchange is followed by a spread of sensitive APIs—reconnaissance, secrets and parameter
access, IAM changes, or compute creation—beyond what routine pod traffic usually shows.
* Update initial_access_assumed_web_identity_session_with_multi_phase_api_use.toml
* Update and rename initial_access_assumed_web_identity_session_with_multi_phase_api_use.toml to lateral_movement_k8_assumed_web_identity_session_with_multi_phase_api_use.toml
* Create initial_access_assume_role_with_web_identity_kubernetes_sa_from_external_asn.toml
* Update initial_access_assume_role_with_web_identity_kubernetes_sa_from_external_asn.toml

* [New] Potential Privilege Escalation in Container via Runc Init
Identifies audit events for `runc init` child processes where the effective user is root and the login user ID is not root. This pattern can indicate privilege escalation or credential separation abuse inside container runtimes, where a process executes with elevated effective privileges while retaining a non-root audit identity.
