Mobile Backend
DevOps & Securitymobile-backendMobile Backend is an Agent Skill for devops & security published in the wgpsec/AboutSecurity repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
移动 App 后端 API 安全测试。当目标是移动应用的后端接口、发现 /api/v1/ 等移动端 API 路径、或需要测试 App 与服务器之间的通信安全时使用。覆盖 API 端点发现、认证机制测试、业务逻辑漏洞、移动端特有的安全问题
QUICK START
How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/wgpsec/AboutSecurity/blob/HEAD/skills/exploit/auth/mobile-backend/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/mobile-backend, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
移动 App 后端 API 安全测试方法论
移动后端 API 和传统 Web 的区别:移动端通常直接调用 REST API(不经过浏览器),认证机制、参数格式、业务逻辑都有移动端特色。

Phase 1: API 端点发现
# spray 目录爆破(推荐)
spray -u http://target -d $ABOUTSECURITY_ROOT/Dic/Web/Directory/Fuzz_common.txt
# 或 ffuf
ffuf -u http://target/FUZZ -w $ABOUTSECURITY_ROOT/Dic/Web/Directory/Fuzz_common.txt -mc 200,301,302,403
# /api/v1/, /api/v2/, /mobile/api/, /graphql
检查文档:/docs, /swagger, /openapi.json, /redoc
App 逆向:抓包(Burp/Charles)| APK 反编译搜索 URL 字符串
Phase 2: 认证机制测试
| 认证方式 | 特征 | 攻击方向 |
|---|---|---|
| JWT | Bearer eyJ... | jwt-attack-methodology |
| API Key | X-API-Key | 泄露检测 |
| OAuth | /oauth/token | oauth-sso-attack |
| 自定义签名 | sign=md5(...) | 签名算法逆向 |
绕过测试:不带 Token 访问 | 过期 Token | 修改 user_id/role | 低权限访问高权限 API
Phase 3: 业务逻辑漏洞
越权访问(IDOR)
GET /api/v1/users/1001/profile → 自己
GET /api/v1/users/1002/profile → 别人?→ IDOR!

注意事项
- 移动 API 通常比 Web 更信任客户端——后端校验更少
- 注意 API 版本差异(v1 可能有漏洞,v2 修复了但 v1 未下线)
