Description

Detects deployments of pods within the kube-system namespace, which could be intended to imitate system pods. System pods, created by controllers such as Deployments or DaemonSets have random suffixes in their names. Attackers can use this fact and name their backdoor pods as if they were created by these controllers to avoid detection. Deployment of such a backdoor container e.g. named kube-proxy-bv61v, could be attempted in the kube-system namespace alongside the other administrative containers.

Detection logic

condition: selection
selection:
  objectRef.namespace: kube-system
  objectRef.resource: pods
  verb: create
