莱鸟啄壳子―我的蜕壳笔记

[引言]   1.轻轻松松找到蜕壳后的OEP。

........2.ESP基本定律和pushad、popad两对基础理论全是错误的。

........3.RVA困惑将荡然无存,莱鸟也可随便玩蜕壳,只需知道简易地加减400000的标准。[预备期专业知识] 只须对PE文档头构造有分步的知道。

  

  我贴了几页烂文就有点儿得意忘形起來,闲来无事又打着了“壳”的歪主意。我要找1个短小精悍的“软壳蛋”来小试下鸡刀,无所谓了挑选到了1个“铁核桃”,差点儿没把门牙啃脱。壮着胆量闯下来,咳~!总算出来,还悟出至少大道理来。

   秀才耍棍棒,还得关键点基本技能。“壳”这一物品对莱鸟一些神秘化,关键缘故是欠缺对PE文档构造的知道,更对RVA的变换头疼。蜕壳以前先将段钢的“数据加密与破译”或罗云彬的“汇编程序设计方案”中有关PE文档构造一部分读五遍就能够应负了!下边用脱FantaMorph.exe 的注册机Keygen.exe(外国人写的)的壳为例,谈点蜕壳构思和方式。(Keygen.exe见附注,请大神认证1个该壳是软還是硬?)

  一、怪异的PE头和蜕壳的初试牛刀

  1.没见过那样的PE头:

  先加16进制编辑器开启keygen.exe文档,看一下它的PE头,给出:
