⚠️ 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.

API 安全测试

When to Use

• An authorized assessment covers API endpoints and you need a structured discovery-to-report workflow.
• Testing API authentication, authorization, or rate-limiting behavior within an approved scope.

适用场景

• REST API 安全测试（OpenAPI/Swagger 驱动或盲测）
• GraphQL 安全审计（内省、批查询、别名过载）
• WebSocket 安全测试
• JWT / OAuth 2.0 认证测试
• BOLA/IDOR/BFLA 授权漏洞检测
• API 限速绕过与 DoS 测试

10 阶段测试流程

Phase 1: API 发现与侦察

主动发现：
□ Vespasian: 无头浏览器爬取 → 自动生成 OpenAPI 3.0 / GraphQL SDL 规范
□ Entropy --discover: 从 robots.txt + JS 文件提取端点
□ Kiterunner / ffuf: 爆破未文档化的端点路径
□ 检查常见路径: /swagger.json, /openapi.json, /graphql, /api-docs

GraphQL 内省（三级尝试）：
  1. 标准内省查询
  2. 精简查询（绕过 WAF 全量封禁）
  3. 仅查 __schema { types { name } }（最小探测）

Phase 2: 认证测试

JWT 分析（jwt_tool / Burp）：
□ alg:none 攻击: 修改头部为 "alg":"none"，清空签名
□ 密钥混淆: RS256 公钥 → HS256 对称密钥
□ 弱 HMAC 密钥爆破: jwt_tool -C -d wordlist.txt
□ 过期/声明篡改: 修改 exp/iat/sub/role 声明
□ kid 注入: ../../etc/passwd → HMAC 签名绕过

OAuth 2.0：
□ redirect_uri 操控 → 授权码泄漏
□ CSRF via state 参数缺失
□ Token 在 Referer 头泄漏
□ PKCE 缺失检测

GraphQL 认证：
□ mutation 通过 GET 请求绕过认证（CSRF）
□ 批查询认证绕过

Phase 3: 授权测试（BOLA/IDOR/BFLA）
