这个驱动是1.40版的,即最后一个还有点用处的版,随后的1.44版将
.text:00019BB9 call Init_IDT_Array
去掉了,也就是放下屠刀了。
驱动的版本在如下地方查看:
.text:000116A5 mov dword ptr [eax+18h], 8Ch
8C = 140 即 1.40版
其中 eax 指向输出缓冲区,即返回到调用驱动的程序,1.40 版和以前的版本Buffer = 0x50,其后的版本为 Buffer = 0x60 但增加的部分没有使用。

1、请问使用什么调试的?sice吗?
2、能介绍一下花指令的去除技巧吗?
3、建议用pe_sections.idc预处理一下,会清晰一些,比如section INIT
我处理后的结果:
