这是一个 Frida VEH 示例

揰掵佲

好了废话不多说，因为太简单了，没什么话可以说，直接上代码。

Talk is cheap. Show you My code.

顺便说一句，丢掉调试器，丢掉各种Loader各种Patcher吧，一个 frida 的 Js 脚本就能干翻一切。
大佬们可以自己实现下 x64 下的代码（尝试下试硬件断点的方式，尝试下 VMP，TEP，WL，SE各种壳的替换机器码）

python3 安装 frida

pip3 install frida frida-tools -i https://pypi.tuna.tsinghua.edu.cn/simple

然后把这个 js 放 exe 同级目录，在目录下 cmd 或者 PS运行下面命令就行

frida -f 010Editor.exe -l ./frida-veh-010-bs.js
