fridaRegstNtv

本项目是利用 frida 获取 Jni RegisterNatives 动态注册的函数，并将其函数地址和对应的 so 打印出来 由于此功能使用频率较高，所以单独拉出一个库，方便使用。

npm build 后，用 Pycharm 打开编辑，可以看到 frida api 代码补全提示。

效果

安装

git clone https://github.com/deathmemory/fridaRegstNtv.git
cd fridaRegstNtv
sudo npm install
npm run build

使用

工程里已经生成了 _fridaRegstNtv.js 可以不用 build 直接使用。

frida -U -l _fridaRegstNtv.js -f com.package.name --no-pause
