ghidra-reverse

Analyze binaries with Ghidra to locate important functions, follow references, and inspect decompiled code, a readable approximation of the original program. Support both interactive investigation and automated batch analysis without a graphical interface.

OriginalShow the original description

Use for free/open reverse engineering with Ghidra (headless or GUI), including decompile, cross-refs, and optional Ghidra MCP workflows when IDA is unavailable.

See how to install

Good for

  • Analyzing binaries when an IDA license is unavailable
  • Locating important functions through strings and imported APIs
  • Running batch decompilation or analysis in CI
  • Retrieving decompiled code and references through configured MCP tools

Ghidra Reverse Engineering

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 读取 ../field-journal/precedent-reverse.md
  2. NOW: 确认需要 Ghidra(无 IDA / 偏好开源 / 批量 headless)
  3. NEXT: 读 ../tool-index.md 查 ghidra / ghidra-mcp 路径
  4. NEXT: 缺工具 → bootstrap ghidra-mcp(若 manifest 支持)或按手动步骤装 Ghidra
  5. ACT: 导入样本 → 自动分析 → 导出关键函数反编译

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?
