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
# HUNT-K8S — Kubernetes & Docker Security ## Crown Jewel Targets K8s API anonymous cluster-admin = full cluster control. docker.sock + RCE = host root. A single privileged-pod create or a kubelet `/run` shell pivots one finding to total compromise. **Highest-value findings:** - **K8s API anonymous cluster-admin** — `system:anonymous`/`system:unauthenticated` bound to a powerful role (classic misconfig: `system:anonymous` in a `ClusterRoleBinding` to `cluster-admin`) → full `kubectl`. Mere anonymous `200` is NOT this (see false-positive section). - **Kubelet `10250` exec/run** — `/run` returns command output directly; `/exec` is a SPDY/WebSocket stream (see Phase 3). Either → RCE in any pod → steal that pod's SA token. - **API-server-mediated kubelet RCE** — `/api/v1/nodes/<node>/proxy/run/...` reaches the kubelet *through* the API server using your (low-priv) token; if RBAC grants `nodes/proxy`, you get pod RCE without touching 10250 directly. Primary 2024-2026 vector. - **etcd `2379` unauth** — every Secret (SA tokens, TLS keys, app creds) stored, often plaintext (unless `EncryptionConfiguration` is set) → full credential dump. …

How to install
mdr add novaestellar/novahaku/hunt-k8s@sha256:d1ba7e194e7a62fdThe line at the top of this page pins the label git:20260910.546fe86, 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.
