“Common” Kubernetes (K8s) hardening suggests a focus on the control plane. But what if a cluster could be backdoored through the kubelet? In this course, Container Infrastructure Analysis with kube-hunter, we will use kube-hunter to investigate a K8s attack. First, you will use kube-hunter to enumerate security weaknesses in a K8s cluster. Second, you’ll use kube-hunter findings (i.e., a discovered kubelet endpoint) to investigate privilege escalation. Third, you’ll leverage the privilege escalation findings to detect a persistence method (i.e., a malicious container image) through Trivy . Fourth, you’ll harden K8s so the aforementioned attack can’t occur again! When you’re finished with this course, you’ll have the skills and knowledge to detect these techniques: System Services (T1569), Exploitation for Privilege Escalation (T1068), and Implant Container Image (T1525).
