功能DLL--完成破解任务的DLL
还记得lpk.dll么?对,就是这样子的顽强战士!今天,让我们为战士完成变身,增加更多理性,完成破解伟业
[思路]:
由于lpk.dll之类使用,不是100%的兼容性,很多壳已经做了anti,我们必须有新的方式让我们的dll入驻。
本教程的思路是:
在exe的00 00 00 00 00 ...魔幻空间里建立新oep,注射载入DLL的Shellcode代码,载入后jmp OldOep原先的Exe入口,完成任务。
提醒:当然如果壳有校验,你注射代码后得修复校验码或直接patch掉校验。
[示范代码]:
此代码调用目录下的usdisp.dll,具体您可进行ascii修改。

完成修改后,用Loadpe之类工具,把oep设置到Shellcode开始的Call位置,完成任务。 太阳太神气了，补丁方式好裤~ 不错 LPK好像真的要倒 这个牛貌似我晚上做梦的时候“看”到过这种方法就是不会写。。。 再膜拜一次。。。。这个代码真的好牛。，， 支持一下 ····
