Ghidra reverse

Free/open reverse engineering with Ghidra (headless or GUI): decompilation, cross-references, scripting, and optional Ghidra MCP workflows when IDA is unavailable.

Use it in my AI

How to use it

  1. Start your plan and connect your AI once
  2. Add the skill to your AI, one time only: press Copy skill and paste it into your AI's instructions: a project in ChatGPT, Claude or Grok, a Gem in Gemini, an agent in Microsoft 365 Copilot, or a rule in Cursor. It stays there for every new chat. In Kimi, paste it at the start of a new chat.
  3. Ask for the task in your own words, or say it directly:
Use the Ghidra reverse skill to help me with this.

Ghidra Reverse Engineering

When to Use

  • Static analysis of binaries without an IDA license.
  • Bulk headless decompilation or scripted analysis across many binaries.

适用场景

  • 无 IDA 许可证时的主逆向入口
  • 批量 headless 分析 / CI 中反编译
  • Ghidra 脚本(Java/Python Jython/PyGhidra)自动化
  • 与 binary-diff / patch-diff-exploit 的 ghidriff 联动

与 IDA 分工

需求优先
已有 IDA MCP 深挖ida-reverse/
开源 / 批量 / 教学本 skill
仅 CLI 快速侦察radare2/

工作流

1. 项目与自动分析

□ 新建 Project → Import 文件 → Analyze(默认分析器)
□ 记录语言/编译器识别结果与基址
□ 标记入口、导出表、字符串 xref

2. 关键函数

□ 从字符串 / 导入 API 反查
□ Decompile 窗口还原算法
□ 重命名函数/变量;写 Plate comment
□ 需要动态时交接 Frida/GDB(reverse-engineering 动态章)

3. Headless(批量)

# 示例:analyzeHeadless 路径因安装而异,MUST 从 tool-index 取
analyzeHeadless /path/to/project Proj -import sample.bin -postScript ExportDecomp.py

4. MCP(若已配置)

□ 确认 ghidra MCP 端口(常见 8765,以 tool-index 为准)
□ 用 MCP 工具拉反编译 / xrefs,禁止猜端口

工具链

工具用途自举
Ghidra反编译主工具手动 release / 包管理器
ghidra-mcpAI 桥bootstrap 能力名 ghidra-mcp
ghidriff补丁差分见 patch-diff-exploit

参考

  • references/ghidra-cheatsheet.md
  • ../ida-reverse/ ../radare2/ ../binary-diff/

路由上下文

上游: MASTER R22 下游: 动态验证 → Frida/GDB;利用 → pwn-chain 同级: ida-reverse(商业深挖)

任务完成自检

  • [ ] 是否基于真实 Ghidra/tool-index 路径?
  • [ ] 是否标注函数地址与重命名?
  • [ ] 是否有可复现步骤?
  • [ ] Checklist / journal?

Limitations

  • Decompiler output is less polished than IDA's for some architectures.
  • Large firmware images may need significant RAM and patience.
