How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Cloud / Container / Kubernetes Security

ACTION REQUIRED(读完后立刻执行)

1. `NOW`: 读取 `../field-journal/precedent-pentest.md` — **云/K8s 测试必须书面授权** 2. `NOW`: case-init + scope;明确账号边界、禁止破坏性操作 3. `NOW`: 确认是云元数据/容器/K8s/IAM,而非普通 Web 扫(后者 `pentest-tools/`) 4. `NEXT`: tool-index;kubectl/aws/gcloud 等多为手动安装 5. `ACT`: 从「身份与暴露面」开始,禁止默认全网扫描

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/IaC | bootstrap `trivy` 若可用 | | kube-bench / kubeaudit | CIS/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?
