这是一个集成了 Dobby Hook 框架的 macOS dylib 项目，通过使用 Dobby Hook 框架来对软件进行辅助增强的操作。Dobby Hook 框架可以帮助实现钩子函数，从而在软件中注入自定义代码，拓展软件功能和提升用户体验。

About

该项目是一个 macOS dylib 项目，集成了 Dobby Hook 框架，旨在通过使用 Dobby Hook 框架对软件进行辅助增强。

开发环境:

• MacOS (关闭 SIP & 允许任何来源)
• xcode 15.2 | clion
• 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|Clion 集成开发调试环境
3. 特征码搜索

Usage

download latest release

tar -xzvf dylib_dobby_hook.tar.gz
cd script 
sudo sh auto_hack.sh

Develop

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 XXX 为例)

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


@interface XXXHack : NSObject <HackProtocol>

@end

@implementation XXXHack

- (NSString *)getAppName {
return @"com.dev.xxx";
}

- (NSString *)getSupportAppVersion {
return @"1.0";
}


- (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"
# The default is injected into the main program, if you need to customize, please edit the variable inject_bin, otherwise do not touch it
# inject_bin="/Applications/Navicat Premium.app/Contents/Frameworks/EE.framework/Versions/A/EE"
# inject_bin="/Applications/${app_name}.app/Contents/MacOS//${app_name}"

dylib_name="dylib_dobby_hook"
prefix="lib"
insert_dylib="${current_path}/../tools/insert_dylib"
chmod a+x ${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 [ ! -d "$app_bundle_framework" ]; then
  mkdir -p "$app_bundle_framework"
fi

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"

# 备份注入程序
if [ ! -f "$app_executable_backup_path" ];
then
    cp "$app_executable_path" "$app_executable_backup_path"
fi


# copy dylib
cp -f "${BUILT_PRODUCTS_DIR}/${prefix}${dylib_name}.dylib" "${app_bundle_framework}"

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