# WeChatIntercept
|
||||
### 微信防撤回插件，一键安装，仅MAC可用。
|
||||
|
||||
1.支持最新版微信3.7.0防撤回；
|
||||
macOS 微信防撤回工具。
|
||||
|
||||
2.新增免认证登录；
|
||||
## 最新版本
|
||||
|
||||
3.新增拦截提示语自定义前缀功能。
|
||||
**支持微信 4.1.9 ~ 4.1.10**，适配微信全新 C++ 架构，通过 DYLD 运行时注入实现防撤回。
|
||||
|
||||
### 功能
|
||||
|
||||
- 对方撤回的消息保留可见
|
||||
- 自己撤回正常工作
|
||||
- 撤回时弹出 macOS 系统通知（显示谁撤回了消息）
|
||||
- 通知开关可随时切换
|
||||
|
||||
### 原理
|
||||
|
||||
通过注入运行时 hook 动态库（`WeChatAntiRevoke.dylib`），拦截微信内部的 `isRevokeMessage()` 函数：
|
||||
|
||||
- 对方撤回 → 返回 false（消息保留）+ 弹出通知
|
||||
- 自己撤回 → 返回 true（正常处理）
|
||||
|
||||
通过读取当前登录用户 ID（完整字符串匹配），精确区分自己与对方。
|
||||
|
||||
### 适用范围
|
||||
|
||||
- macOS 微信 4.1.9、4.1.10
|
||||
- Apple Silicon（arm64）及 Intel（x86_64）
|
||||
- macOS Sequoia / Sonoma / Ventura 等（自动处理 provenance 限制）
|
||||
|
||||
### 使用
|
||||
|
||||
```bash
|
||||
chmod +x patch.sh # 添加可执行权限
|
||||
./patch.sh # 安装防撤回
|
||||
./patch.sh openNotify # 开启撤回通知
|
||||
./patch.sh closeNotify # 关闭撤回通知
|
||||
./patch.sh --uninstall # 卸载
|
||||
./patch.sh --help # 帮助
|
||||
```
|
||||
|
||||
首次运行可能需要约 30 秒（自动解除系统文件保护并重签名）。
|
||||
|
||||
### 配置
|
||||
|
||||
配置文件路径：`~/.config/antirevoke/config`
|
||||
|
||||
```ini
|
||||
notify=1 # 1=开启撤回通知, 0=关闭
|
||||
```
|
||||
|
||||
安装时默认开启通知，也可通过命令随时切换：
|
||||
|
||||
```bash
|
||||
./patch.sh openNotify # 等同于设置 notify=1
|
||||
./patch.sh closeNotify # 等同于设置 notify=0
|
||||
```
|
||||
|
||||
修改后立即生效，无需重启微信。
|
||||
|
||||
### 依赖
|
||||
|
||||
macOS 系统自带工具，无需额外安装：
|
||||
- clang（Xcode Command Line Tools）
|
||||
- python3
|
||||
- codesign
|
||||
- tar
|
||||
|
||||
如未安装 Xcode Command Line Tools，运行：`xcode-select --install`
|
||||
|
||||
### 调试
|
||||
|
||||
```bash
|
||||
./patch.sh --debug # 调试模式（不安装 hook，仅签名允许 lldb attach）
|
||||
cat /tmp/antirevoke_debug.log # 查看运行时日志
|
||||
```
|
||||
|
||||
### 已知限制
|
||||
|
||||
- **聊天框内无撤回提示**：由于微信 4.x 的架构限制（C++ 实现 + 符号 strip + 数据库加密），无法在聊天界面内插入系统消息。替代方案为 macOS 系统通知。
|
||||
|
||||
- **为什么不能像旧版那样在聊天框内显示提示？**
|
||||
|
||||
旧版微信 macOS（3.x）使用 Objective-C，可通过 Method Swizzling 调用内部消息插入 API。4.x 版本核心逻辑全部迁移到 C++（仅剩 65 个 ObjC 类，90MB+ 代码段，符号已 strip），撤回处理通过虚函数 + 加密数据库 + 协程调度完成，无法稳定地从外部构造调用链插入消息。
|
||||
|
||||
### 技术文档
|
||||
|
||||
详细的逆向分析过程和适配指南见 [`doc/reverse-engineering-guide.md`](doc/reverse-engineering-guide.md)。

|
||||
|
||||
## 旧版本
|
||||
|
||||
支持微信 3.7.0 及更早版本，基于 DYLD 注入 + Method Swizzling，支持撤回提示和自定义前缀。
|
||||
|
||||
### 功能
|
||||
|
||||
1. 防撤回（支持聊天框内拦截提示）
|
||||
2. 免认证登录
|
||||
3. 拦截提示语自定义前缀

||||
|
||||
### 使用方法
|
||||
|
||||
自定义防撤回提示前缀：安装成功后重启微信，屏幕左上角微信菜单栏有个小助手菜单，修改后点击关闭即可。

||||
|
||||
安装方法：cd到WeChatIntercept文件夹，将Install.sh文件拖到终端，输入密码回车，然后重启微信即可。
|
||||
|
||||
卸载方法：将Uninstall.sh文件拖到终端，然后回车。
|
||||
|
||||
此插件将一直更新，欢迎Star！
|
||||
- **安装**：cd 到 WeChatIntercept 文件夹，将 `Install.sh` 拖到终端，输入密码回车，重启微信。
|
||||
- **卸载**：将 `Uninstall.sh` 拖到终端回车。
|
||||
- **自定义前缀**：安装成功后重启微信，屏幕左上角微信菜单栏有个小助手菜单，修改后点击关闭即可。
|
||||
|
||||
### 常见问题
