⚠️ 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.

Thick Client Security Testing

When to Use

• Assessing a desktop application's security posture.
• Checking whether client-side trust decisions can be subverted.

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 Fr
