# 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

```text
□ 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

```text
□ 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)

```bash
# 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)

```text
□ 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-mcp | AI 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?
