驱动插ring3线程执行代码

近日有在写一个小东西
需要在内核态中运行一个WIN32程序
之前提到的插入APC可以满足部分要求
但是一到WIN7 x86平台下就崩溃了
WIN7下只能插入第三方的进程
一插入系统进程就崩溃，但是这样满足不了我们猥琐的想法
- - 后来找到了一段代码是注入RING3线程的

基本流程就是查找系统中某个进程比如explorer.exe
然后遍历线程链表，判断线程是否是RING3的线程，
而且不是被挂起的。（这个无所谓的）。。。
找到符合要求的线程之后在对方进程中申请一段内存来存放我们自己的ShellCode 代码
然后修改线程的_KTRAP_FRAME中的EIP的值，使线程跑起来的时候先运行我们的自己的
代码，运行完了之后跳回到原来的EIP去指定。。。
需要用到两个未公开的函数:ZwSuspendThread,ZwResumeThread
一个是挂起线程来方便我们修改EIP的一个是恢复线程使它跑起来

再说说在RING0下搜索RING3 API地址的方法
其实就是从_EPROCESS中得到PEB结构
从PEB中的ldr中的InInitializationOrderMoudleList链表中去查找Kernel32.dll的基地址
通常来说WINXP中了链表的第一项就是Kernel32.dll的基地址
而到了win7 它就存在第二项了 win7下第一项是kernelbase.dll的基地址（这个好像是一个kernel32.dll的壳）
不多说了看代码吧
