About

xcode 开发 dylib , 基于跨平台的 dobby HOOK 框架来构建跨平台的通杀补丁.
你妈再也不用担心你只能跑 Rosetta 了..

开发环境:

• MacOS (关闭 SIP)
• xcode 15.2
• dobby
• insert_dylib
• hopper | ida

目录结构 :

1. dylib_dobby_hook: 源码
2. libs: 项目依赖的开源 dobby 库
3. release: build 后的成品
4. script:
   • hack.sh 自定义注入脚本 sudo sh hack.sh
   • auto_hack.sh 妹妹全自动注入脚本 sudo sh auto_hack.sh
5. tools: insert_dylib 开源注入工具

Feat

1. 跨平台 HOOK
2. Xcode 集成开发调试环境
3. 特征码搜索

Quick Start

git clone https://github.com/marlkiller/dylib_dobby_hook.git 
cd script 
sudo sh auto_hack.sh

Develop

关键 hook 函数,可以参考帖子(以 TabpePlus 该软件为例) : https://www.52pojie.cn/thread-1739112-1-1.html

0x0

基础代码已经完成, 为了兼容更多的 app 补丁, 使用了适配器模式来进行扩展

0x1 定义实现类(以当前 TablePlus 为例)

#import <Foundation/Foundation.h>
#import "TablePlusHack.h"
#import <objc/runtime.h>

@implementation TablePlusHack


- (NSString *)getAppName {
    return @"com.tinyapp.TablePlus";
}

- (NSString *)getSupportAppVersion {    
    return @"5.8.2";
}

- (BOOL)hack {
    
#if defined(__arm64__) || defined(__aarch64__)
    // do arm something..
#elif defined(__x86_64__)
    // do x86 something..
#endif
    
    return YES;
}
@end

0x2 Build & 注入

编译后, 会得到一个我们的 dylib 补丁
然后编写 shell 脚本,来注入

current_path=$PWD
echo "当前路径：$current_path"

app_name="DevUtils"

# 默认注入到主程序中，如果需要自定义，请编辑 inject_bin 变量，否则不要碰它
# inject_bin="/Applications/Navicat Premium.app/Contents/Frameworks/EE.framework/Versions/A/EE"
# inject_bin="/Applications/${app_name}.app/Contents/MacOS//${app_name}"

# release dylib
dylib_name="dylib_dobby_hook"
prefix="lib"
insert_dylib="${current_path}/../tools/insert_dylib"

BUILT_PRODUCTS_DIR="${current_path}/../release"

app_bundle_path="/Applications/${app_name}.app/Contents/MacOS/"
app_bundle_framework="/Applications/${app_name}.app/Contents/Frameworks"

if [ -n "$inject_bin" ]; then
    app_executable_path="$inject_bin"
else
    app_executable_path="${app_bundle_path}/${app_name}"
fi
app_executable_backup_path="${app_executable_path}_Backup"

# 注入前,备份程序
cp -f "${insert_dylib}" "${app_bundle_path}/"
if [ ! -f "$app_executable_backup_path" ]; 
then
    cp "$app_executable_path" "$app_executable_backup_path"
fi

# 复制 dylib 到目标程序下,执行注入
cp -f "${BUILT_PRODUCTS_DIR}/${prefix}${dylib_name}.dylib" "${app_bundle_framework}"
cp -f "${BUILT_PRODUCTS_DIR}/libdobby.dylib" "${app_bundle_framework}"

"${app_bundle_path}/insert_dylib" --weak --all-yes "@rpath/${prefix}${dylib_name}.dylib" "$app_executable_backup_path" "$app_executable_path"
