桌面厚客户端安全测试

用于授权安全测试桌面厚客户端，包括本地存储、更新通道、IPC、流量及客户端侧信任边界。

桌面厚客户端安全测试 是什么？

该技能用于在授权场景下对桌面厚客户端进行安全测试。它覆盖了Windows、macOS和Linux上的GUI客户端及其服务伴生应用。测试范围包括本地攻击面（如配置存储、凭证、DLL劫持、IPC通信）、网络攻击面（如TLS绕过、证书钉扎、API越权）以及更新/供应链通道。工作流首先要求构建信任边界图，明确本地与网络面的攻击面，再借助逆向工程（如dnSpy、IDA、Ghidra、Frida）验证发现的问题。该技能非常适合评估Electron、Qt、.NET WinForms/WPF等架构的客户端应用，并结合Burp、Process Monitor等工具链完成系统性安全审查。

文档

桌面厚客户端安全测试 是做什么的？

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？

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

api-security

Use for authorized security assessment of REST, GraphQL, WebSocket, or SOAP APIs, including discovery, authentication, authorization, rate-limit, and CI/CD testing.

apk-reverse

在 CLI 环境下做 Android APK 逆向时使用。适用于 APK 解包、Java 反编译、smali 修改、重打包、Frida 动态 Hook，以及按需切换到 so/native 分析。优先使用本机已安装的 jadx、apktool、frida、adb、ida-reverse、radare2。

attack-chain

Use for authorized multi-stage attack-path planning and orchestration when a task spans reconnaissance, initial access, privilege escalation, lateral movement, or impact assessment. Route single-stage tasks directly to their specialist skill.

binary-diff

binary-ninja-reverse

Use for authorized binary analysis in Binary Ninja, including HLIL/MLIL/LLIL inspection, strings/imports/exports, cross-references, types, patch review, Python API automation, and optional Binary Ninja MCP or localhost HTTP integration.

browser-automation

|

browser-extension-reverse

Use for authorized reverse engineering of browser extensions (Chrome/Firefox) including manifest analysis, background workers, and extension-based credential or traffic logic recovery.

case-review

Reviews a reverse-skill case package for scope readiness, Evidence to Finding to Path traceability, work item coverage, timeline references, and optional artifact hash integrity before report handoff.

cloud-k8s

Use for authorized cloud, container, and Kubernetes security assessment including metadata SSRF, IAM misconfig, container escape paths, and cluster RBAC review.

code-audit

Use for authorized source-code security review and SAST workflows including Semgrep, CodeQL patterns, dangerous API hunting, and fix verification.

ctf-sandbox

Thin PRIMARY for CTF / AWD / 靶场 multi-type orchestration. Hands off to the sidecar CTF-Sandbox-Orchestrator. Use when the user says CTF, AWD, 靶场, or 比赛题 and no more specific pwn/APK/IDA route already won.

database-security

Use for authorized database security assessment covering PostgreSQL/MySQL/MSSQL/Mongo/Redis exposure, authz, UDF/command paths, and misconfiguration review.

diagram-generator

generate, refine, validate, and render diagrams from natural language, notes, code snippets, schemas, tables, or existing diagram source. use for flowcharts, swimlanes, sequence diagrams, state diagrams, er diagrams, class diagrams, architecture/c4-style diagrams, dependency graphs, gantt charts, mind maps, user journeys, sankey-style flows, org charts, network graphs, and other visual models. supports mermaid by default, graphviz dot for complex graph layout, plantuml for uml-heavy engineering diagrams, and svg output when direct markup is more reliable.

digital-forensics

Use for authorized digital forensics including memory dumps, disk timelines, PCAP investigation, artifact triage, and IR evidence preservation.

docs-generator

dotnet-reverse

.NET / C# 二进制逆向。当目标是 .NET assembly（PE 头含 CLR、.exe/.dll 托管程序）、C# 编译产物（含 NativeAOT）、红队 Sharp* 工具（Rubeus / SharpHound / SharpHound 等）、.NET 混淆程序（ConfuserEx / SmartAssembly / Babel / Eazfuscator）、.NET loader / info-stealer / 套壳 malware 时使用。优先用 dnSpyEx + de4dot，需要 AI 直接操作时联动 dnSpy MCP。不用于纯 native 二进制（走 reverse-engineering / ida-reverse）。
