  • Kubernetes pod creation with host network Informational Cloud 3 variations

    An identity created a Kubernetes pod attached to the host network. This may indicate an adversary attempting to access services bound to localhost, sniff traffic on any interface on the host, and potentially bypass the network policy.

    Required data: AWS Audit Log Azure Audit Log Gcp Audit Log Kubernetes Audit Logs
    Detector tags: Kubernetes - API
    Attacker's goals: Access services bound to localhost. Sniff traffic on any interface on the host. Bypass network policy.
    Investigative actions: Check the identity's role designation in the organization. Inspect for any unusual access to localhost services. Inspect for any network sniffing tool being used inside the Kubernetes Pod.
