关于Windows内核空间操作的一些说明

   首先对被我误导的人说声对不起了。我在论坛中发的那篇贴(用户态隐藏进程的通用版本)真是乱七八糟(-_-我也是受害者)。在XP和WINDOWS 2003中用那种方法都是行不通的,而且在20043中的偏移也是错的。这里我先把XPSP2和2003中的EPROCESS整理出来给大家看一下:

关于如何在xp和2003中读写内核空间,TK大哥已经说的很清楚了,用ZwSystemDebugControl函数的8,9调用号就可以了。
这里给大家一个写的示例程序,大家改一下放到程序中,再做一下系统的判断就可以达到通用性了。

这里我还对TK大哥在04峰会上讲的内容做了验证,发现SessionProcessLinks在XP和2003中都是可以用来权举进程的,但是在2000中都为0x00000000,
也就是说,在2000中不能通过它进行进程检查了,只能通过WorkingSetExpansionLinks来权举进程。这里TK大哥也没做说明,前面一直没怀疑过TK大哥的准确性,
花了很长时间去执行,都没成功,用WINDBG一看就出来了。哎,看来什么事还得自己验证一下啊。5555。。。下面是对TK大哥讲的内容的实现代码:
