使用代码注入来实现进程隐藏 而不是使用DLL注入来实现进程隐藏
没有什么高级技术 纯体力活 原理就不说了 只是没有通过DLL注入 来实现HOOK API

后记：第一次没有照着书 打代码 也找不到C 注入代码的例子 能找到的都是DLL注入
原理早就知道了 真的写一遍 不容易
整个编写的过程 碰到了很多问题 最终都解决了 轻松了

使用代码注入来实现进程隐藏 而不是使用DLL注入来实现进程隐藏
没有什么高级技术 纯体力活 原理就不说了 只是没有通过DLL注入 来实现HOOK API
纯粹注入代码 邪恶二进制上 也有个代码注入的 只是用了一个未公开的函数，我还看不懂
= =本来想用汇编写的 发现汇编注入代码远比C注入代码来的繁 所以用C实现了
主要功能就是 隐藏进程 不过RING3的似乎没多大用 练习而已

后记：第一次没有照着书 打代码 也找不到C 注入代码的例子 能找到的都是DLL注入
原理早就知道了 真的写一遍 不容易
整个编写的过程 碰到了很多问题 最终都解决了 轻松了
