⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

  1. Ask the user to state the exact target URL, IP, account, or resource.
  2. Ask the user to confirm written authorization and the permitted scope.
  3. Show the exact command(s) and explain their expected effect.
  4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

Cloud / Container / Kubernetes Security

When to Use

  • Assessing cloud workload or Kubernetes cluster security within an approved scope.
  • Reviewing IAM/RBAC configurations for privilege-escalation paths.

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

□ 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

# 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

□ 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

□ 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

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

□ 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

工具链

工具用途自举
kubectl集群交互手动
trivy镜像/IaCbootstrap trivy 若可用
kube-bench / kubeauditCIS/配置手动
pacu / scoutsuite云审计（授权）手动
nuclei已知云漏洞模板bootstrap nmap/nuclei 生态

参考

  • references/k8s-cloud-checklist.md
  • CTF 对照：../../CTF-Sandbox-Orchestrator/competition-agent-cloud/
  • ../supply-chain-security/ ../pentest-tools/

路由上下文

上游: MASTER R23
下游: 拿到节点 shell → attack-chain / windows-ad；镜像漏洞 → supply-chain
MUST NOT: 未授权扫公有云其他租户

任务完成自检

  • 是否限定在授权账号/cluster？
  • 发现是否含复现与影响？
  • 是否避免破坏性操作？
  • 报告 / journal？

Limitations

  • Cloud provider API calls may incur cost and trigger alerts; coordinate with the owner.
  • Escape-path validation must stay inside disposable lab clusters.
