HOOK别人的dylib(HOOK cydia里面的插件)

 

以下仅做我在hook 中的记录,

环境 VM PRO 15

  MAC OS 15

  Xcode 11.2

工具 monkeydev

  install_name_tool

  otool 

思路:将要hook 的dylib,注入到我们新建的xcode工程中,然后拿着protuct 放到monkeydev 里去正常hook。

 

1.将dylib扔进hopper,发现有一个RobborVC,随新建一个Xcode工程,在viewDidAppear中,present进RobborVC,

        Class cls =NSClassFromString(@"RobotVc");
        id Vc = [[cls alloc]init];
        [self presentViewController:Vc animated:YES completion:^{
             
         }];

 

1.使用 0tool -l 查看dylib 的依赖路径,如下图,发现dylib 还依赖了一个libsubstrate.dylib,

 

 

 

2.将上面两个dylib 拖入新建Xocde的根目录中

 

3.使用install_name_tool修改dylib 依赖路径,

 

install_name_tool [-id name] input 修改对自身的依赖

install_name_tool [-change old new] input 修改对第三方库的依赖


如:

install_name_tool -id  @@executable_path/Frameworks/CXZDZW.dylib /Users/jack/Desktop/testDLb/CXZDZW.dylib
install_name_tool -change @loader_path/libsubstrate.dylib /Users/jack/Desktop/testDLb/libsubstrate.dylib

4.载build phases 新增 run script 增加bash脚本,进行copy dylib进 $BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH  目录下,并签名


  if [-f $BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH/CXZDZW.dylib];then
  rm -rf $BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH/CXZDZW.dylib
  fi
  if [-f $BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH/libsubstrate.dylib];then
  rm -rf $BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH/libsubstrate.dylib
  fi

if [[ "${CONFIGURATION}" == "Debug" ||  "${CONFIGURATION}" == "DailyBuild" ]]; then
echo "begin copy CXZDZW dylibs into product"
cp -R $PROJECT_DIR/CXZDZW.dylib $BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH
cp -R $PROJECT_DIR/libsubstrate.dylib $BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH
if [ "${CODE_SIGNING_REQUIRED:-}" != "NO" ]; then
/usr/bin/codesign --force --sign "${EXPANDED_CODE_SIGN_IDENTITY}" "$BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH/CXZDZW.dylib"
/usr/bin/codesign --force --sign "${EXPANDED_CODE_SIGN_IDENTITY}" "$BUILT_PRODUCTS_DIR/$FRAMEWORKS_FOLDER_PATH/libsubstrate.dylib"
fi
fi

 

 5.找到.app文件,拖入monkeydev中,hook 即可
