ShellCode注入程序

程序功能是利用NtQueueApcThreadEx注入ShellCode到一个进程中，程序运行后会让你选择模式，按1为普通模式，所需的常规API接口都是使用Windows原本正常的API；在有游戏保护的进程中Windows原本正常的API无法使用，这时候需要选择内核模式，按2选择内核模式。

内核模式下使用的一些关键API都是我自己在ring0从0实现的，本帖仅开源普通模式下的代码。内核模式下使用的关键API以及调用框架不开源。

选择模式之后需要输入被注入进程的PID

项目包含三个源代码文件：1.源.cpp

2.fun.asm

3.fun.h

首先是源.cpp文件代码：

shellCode的功能是给被注入进程设置一个键盘钩子，TAB键。
