# macOS / Mach-O Reverse Engineering

## 适用场景

- Mach-O 可执行文件 / dylib / framework
- .app bundle、LaunchAgent/Daemon
- Objective-C / Swift 符号与 runtime
- 公证/签名、Hardened Runtime、TCC 相关行为分析
- macOS 恶意软件静态/动态分析(联合 malware-analysis)

## 工作流

### 1. 包体与签名

```bash
file target
codesign -dv --verbose=4 target
spctl -a -vv target 2>&1
otool -L target
```

### 2. 静态

```text
□ class-dump / swift-demangle / Hopper / Ghidra / IDA
□ 字符串与 XPC 服务名、TCC 敏感 API
□ LC_LOAD_dylib 依赖与 rpath
```

### 3. 动态

```text
□ lldb / Frida
□ fs_usage / log stream 观察
□ 网络:联合 protocol-reverse 或代理
```

## 工具链

| 工具 | 用途 |
|------|------|
| otool / nm / codesign | 系统自带 |
| Hopper / Ghidra / IDA | 反编译 |
| class-dump / dsdump | ObjC |
| Frida / lldb | 动态 |
| jtool2 | Mach-O |
