Kubernetes cluster attack techniques covering the full attack lifecycle from initial foothold in a pod to cluster-wide compromise. Covers service account token theft and impersonation, RBAC misconfiguration exploitation including wildcard permissions and privilege escalation via role binding, direct etcd access for secret extraction, kubelet API abuse on port 10250 and read-only port 10255, pod escape via hostPID hostNetwork and hostPath volume mounts, Kubernetes secrets enumeration and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Kubernetes Cluster Attacks You have access to a Kubernetes environment, either through a compromised pod, stolen kubeconfig, or exposed API server. Your objective is to escalate privileges, move laterally, and compromise the cluster or underlying cloud infrastructure. Kubernetes security depends on RBAC policies, network policies, admission controllers, pod security standards, and cloud IAM integration. Each misconfiguration opens a path to deeper access. This skill covers systematic enumeration, privilege escalation, secret extraction, and cluster-wide compromise techniques. ## Quick Workflow 1. Determine your initial position: pod shell, stolen token, exposed API, or kubeconfig file. 2. Enumerate service account permissions, cluster roles, and accessible resources. 3. Identify escalation vectors: RBAC gaps, kubelet exposure, hostPath mounts, cloud metadata access. 4. Escalate privileges by chaining misconfigurations or abusing overprivileged service accounts. 5. Extract secrets, pivot to other namespaces, and target the control plane. 6. Leverage cloud metadata or etcd access for infrastructure-wide compromise. --- ## Phase 1: Initial Enumeration …

How to install
mdr add miosa-osa/osa/offensive-k8s-attacks@sha256:3c70aa3b5fe5248eThe line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
