# Thick Client Security Testing

## 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

```text
□ 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

```text
□ 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

```text
□ 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

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

## 工具链

| 工具 | 用途 |

| Burp / mitmproxy | 流量 |
| dnSpy / IDA / Ghidra | 逆向 |
| Sysinternals | Windows 面 |
| asar / nexe 检测 | Electron |
