想学Hook技术的兄弟看过来.........

njhhack 2001-06-21 08:23:00

兄弟谢谢你对我的理解,看到有些人骂我弱,我真得感到很弱,因为我是菜鸟,但我想我懂的东西别人不一定懂,因此想把我懂的东西让大家共享,我没有别的意思,我没有大的能耐,看到有的兄弟说Delphi下的Hook不好做,所以在下把每个Hook都在Delphi做了一下,觉得没啥问题,而且处理的方法较新颖,拿来让兄弟们探讨,这回我说的是Hook，不是深度进程隐藏,还望各位高人不要骂我弱哟,我好害怕哪,不过上面好多高手说的进程隐藏好象只能在nt,w2k下用,win9x下没这种函数呀,在win9x中有个好办法就是用cih病毒的方法,直接进入ring0级啦,不过太难了呀,哪位高人知道win9x下隐藏的好方法,教我呀,我好想学呀,关于hook问题,有不懂的问我就行,不过有的Hook我只做了个框架,没有具体实用作用,要做的兄弟自已完善就行了,呵呵,代码在下面,自已看啦..........
