Thick Client Security Testing

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 读取 ../field-journal/precedent-pentest.md
  2. NOW: 确认目标是 桌面厚客户端(Win/macOS/Linux GUI 或服务伴生),非纯 Web
  3. NOW: case-init;安装包来源与测试账号写入 scope
  4. NEXT: 工具(Burp 上游代理、进程监控、逆向工具)
  5. ACT: 信任边界图 → 本地面 → 网络面 → 更新/供应链

适用场景

  • C/S 架构客户端、Electron/Qt/.NET WinForms/WPF
  • 本地配置/凭证存储、IPC、命名管道
  • 客户端强制校验绕过研究(授权)
  • 自动更新通道与代码签名验证

工作流

1. 建边界

□ 进程树、子进程、驱动/服务
□ 监听端口与出站域名
□ 本地敏感路径:%APPDATA%、Keychain、注册表

2. 本地攻击面

□ 明文配置、硬编码密钥、调试开关
□ DLL 劫持/搜索顺序(Windows)
□ 数据库文件(SQLite)权限与加密
□ IPC:谁可连接?是否鉴权?

3. 网络面

□ 系统代理 / 应用自定义 TLS
□ 证书钉扎 → 联合 mobile/js 方法学或 Frida
□ API 越权:客户端隐藏的管理接口

4. 逆向验证

□ .NET → dotnet-reverse;原生 → ida/ghidra;Electron → asar + js-reverse

工具链

工具用途
Process Monitor / API Monitor行为
Burp / mitmproxy流量
dnSpy / IDA / Ghidra逆向
SysinternalsWindows 面
asar / nexe 检测Electron

参考

  • references/thick-client-checklist.md
  • ../dotnet-reverse/ ../ida-reverse/ ../js-reverse/ ../api-security/

路由上下文

上游: MASTER R32
下游: 纯协议 protocol-reverse;供应链更新 supply-chain-security

任务完成自检

  • 是否画出信任边界?
  • 本地+网络面是否都覆盖?
  • Checklist?
