cloud-k8s
Allows the agent to assess cloud, container, and Kubernetes security. It checks IAM configurations and escape paths.
What it does
This tool helps check the security of cloud, container, and Kubernetes environments. It looks for misconfigurations that attackers could exploit.
When to use it
- ✓When testing the security of a cloud account.
- ✓When assessing the security of containerized applications.
- ✓When reviewing permissions and configurations in Kubernetes clusters.
Example of what to ask your AI
“Check the security of my AWS account and Docker containers.”

Cloud / Container / Kubernetes Security
ACTION REQUIRED(读完后立刻执行)
NOW: 读取../field-journal/precedent-pentest.md— 云/K8s 测试必须书面授权NOW: case-init + scope;明确账号边界、禁止破坏性操作NOW: 确认是云元数据/容器/K8s/IAM,而非普通 Web 扫(后者pentest-tools/)NEXT: tool-index;kubectl/aws/gcloud 等多为手动安装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 |

FAQ
Do I need permission to use this tool?
Yes, it is essential to have written authorization before performing any security testing on cloud or Kubernetes environments.
Can this tool cause damage?
No, the tool is designed for analysis and should not perform destructive operations. It's important to clearly define the scope and avoid aggressive scans.
What is SSRF?
SSRF (Server-Side Request Forgery) is a vulnerability that allows an attacker to trick the server into making HTTP requests to a domain of the attacker's choosing.
Details
Original description by the author
Use for authorized cloud, container, and Kubernetes security assessment including metadata SSRF, IAM misconfig, container escape paths, and cluster RBAC review.
