cloud-k8s SKILL.md skillA

cloud-k8s from coco-research/coco is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add coco-research/coco/cloud-k8s@git:20260914.480426e

Pins git:20260914.480426e in mdr.lock. Pin the fingerprint instead.

Use for authorized cloud, container, and Kubernetes security assessment including metadata SSRF, IAM misconfig, container escape paths, and cluster RBAC review.

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

# Cloud / Container / Kubernetes Security

## 适用场景

- 云元数据 SSRF（169.254.169.254 / IMDS）
- IAM 过度权限、公开存储桶、错误安全组
- Docker/containerd 逃逸路径评估
- Kubernetes RBAC、Secrets、Admission、供应链镜像
- 容器镜像漏洞（可联动 `supply-chain-security/`）

## 工作流

### Phase 1 — 身份与边界

```text
□ 当前身份：云 AK/SK、K8s SA、节点 SSH？
□ 范围：单账号 / 单 cluster / 单 namespace
□ 网络档：authorized_target_only
```

### Phase 2 — 云控制面

```bash
# 示例（按厂商替换；MUST 在授权账号内）
aws sts get-caller-identity
aws s3 ls
# Azure / GCP 对应 identity 命令
```

```text
□ 公开桶 / 错误 ACL
□ 元数据：IMDSv1 vs v2；SSRF 链
□ 角色可扮演（PassRole）与横向
```

### Phase 3 — 容器

```text
□ 是否 privileged / hostPath / hostNetwork
□ capabilities（SYS_ADMIN 等）
□ 可写宿主机路径 → 逃逸候选
□ 镜像历史与已知 CVE → Trivy
```

### Phase 4 — Kubernetes

```bash
kubectl auth can-i --list
kubectl get pods,secrets,svc -A
kubectl get clusterrolebindings
```

```text
□ SA token 挂载与权限
□ 危险 admission webhook 缺失
□ etcd / dashboard 暴露
□ 网络策略是否默认放行
```

How to install

The exact contents, by fingerprint

mdr add coco-research/coco/cloud-k8s@sha256:abc70e061e8bf38c

The line at the top of this page pins the label git:20260914.480426e, 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.
