This project is a macOS dylib project, aiming to enhance software through the use of the Hook framework.

Development Environment:

• macOS (SIP disabled & allow any source)
• Xcode 15.2 | CLion
• Hopper | IDA

Directory Structure:

1. dylib_dobby_hook: Source code
2. libs: Libraries that the project depends on
   • tinyhook
3. release: Built product libraries
4. script:
   • auto_hack.sh: One-click script sudo bash auto_hack.sh
5. tools:
   • insert_dylib: Open-source static injection tool
   • dynamic_inject: Dynamic injection tool [SIP OFF]
   • process_inject: Process injection tool [BETA][SIP OFF]

1. Cross-platform [intel/apple] HOOK
2. Integrated development and debugging environment with Xcode|CLion|VSCode
3. Signature code search

Check the full list of supported apps here.

download latest release

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

The basic code has been completed. To be compatible with more app patches, the adapter pattern is used for extension.

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


@interface XXXHack : HackProtocolDefault

@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

After compilation, we will get our dylib patch. Then write a shell script to inject.

## Static Injection
cp -f source_bin source_bin_backup 
"${insert_dylib}" --weak --all-yes "${YOUR_BUILD_PATH}/libdylib_dobby_hook.dylib" "source_bin_backup" "source_bin"

## Dynamic Injection [SIP OFF]
./dynamic_inject "xxx.app" "${YOUR_BUILD_PATH}/libdylib_dobby_hook.dylib"

## Process Injection [SIP OFF]
./process_inject "$pid" "${YOUR_BUILD_PATH}/libdylib_dobby_hook.dylib"
