厚客戶端安全測試

用於授權的安全測試，針對桌面厚客戶端，包括本地儲存、更新通道、IPC、流量和客戶端信任邊界。

厚客戶端安全測試 是什麼？

這是一個專門針對桌面厚客戶端（如Win/macOS/Linux GUI應用程式或服務伴生程式）進行授權安全測試的技能。它涵蓋了客戶端-伺服器架構、Electron、Qt、.NET WinForms/WPF等常見平台。該技能提供了一個系統化的測試工作流程，包括建立信任邊界、探索本地攻擊面（如明文配置、硬編碼金鑰、DLL劫持、IPC鑑權）、分析網路面（如代理設定、TLS證書釘扎、API越權），以及使用逆向工具（如dnSpy、IDA、Ghidra）進行驗證。它還整合了工具鏈（如Process Monitor、Burp Suite、Sysinternals）和參考文檔（如checklist、其他技能模組），以確保評估的完整性和效率。

厚客戶端安全測試 是做什麼的？

ACTION REQUIRED（讀完後立刻執行）

  1. NOW: 讀取 ../field-journal/precedent-pentest.md
  2. NOW: 確認目標是 桌面厚客戶端（Win/macOS/Linux GUI 或服務伴生），非純 Web
  3. NOW: case-init；安裝包來源與測試帳號寫入 scope
  4. NEXT: 工具（Burp 上游代理、進程監控、逆向工具）
  5. ACT: 信任邊界圖 → 本地面 → 網路面 → 更新/供應鏈

適用場景

  • C/S 架構客戶端、Electron/Qt/.NET WinForms/WPF
  • 本地配置/憑證儲存、IPC、命名管道
  • 客戶端強制校驗繞過研究（授權）
  • 自動更新通道與代碼簽名驗證

工作流

1. 建邊界

□ 進程樹、子進程、驅動/服務
□ 監聽端口與出站域名
□ 本地敏感路徑：%APPDATA%、Keychain、註冊表

2. 本地攻擊面

□ 明文配置、硬編碼金鑰、調試開關
□ DLL 劫持/搜索順序（Windows）
□ 資料庫文件（SQLite）權限與加密
□ IPC：誰可連接？是否鑑權？

3. 網路面

□ 系統代理 / 應用自定義 TLS
□ 證書釘扎 → 聯合 mobile/js 方法學或 Frida
□ API 越權：客戶端隱藏的管理接口

4. 逆向驗證

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

工具鏈

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

參考

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

路由上下文

上游: MASTER R32
下游: 純協議 protocol-reverse；供應鏈更新 supply-chain-security

任務完成自檢

  • 是否畫出信任邊界？
  • 本地+網路面是否都覆蓋？
  • 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.
