Themida V1.3.5.5脱壳之delphi程序
【破解作者】 windycandy【使用工具】 OD,PEID,LordPE,ImprtREC F1.6

【软件简介】 今年我们的英雄成功crackThemida,可以说是解密界的一新闻,但themia的脱壳
教程并不多见,近日在一蓑烟雨读得fly大侠大作<Themida V1.1.1.0 无驱动版
试炼普通保护方式脱壳>,成功将Themida.V1.3.5.5.加壳的98notepad脱掉,
遂用Themida.V1.3.5.5.对delphi编写的程序进行试验(将入口virtualization
调至0),本脱文可以说是fly大大那篇脱文的翻版,没有什么技术含量,献给与我一样
的菜鸟分享,高手则略过.如果需要对其中的原理进一步了解,请参照fly大大的文章

【加壳方式】 Themida.V1.3.5.5
【破解声明】 我是一只小菜鸟，偶得一点心得，愿与大家分享：）

【脱壳过程】

Alt+M 打开内存察看窗口，在代码段设置内存写入断点。连续Shift+F9三次后中断在

这里说明一下,用98的notepad练习的时候,OD载入到这里只用两次就可以了,这个程序一共用了5次,可能是由于不同
语言编写的缘故,但是009327FC 和00939043 的汇编代码是一样的.
中断后,上下拉动鼠标,可以找到一段长长的代码: (对照fly大侠的注析来看这段代码)

写好代码后,取消先前在code段下的内存断点,shift+F9,中断在00939171,到这里已经获得了IAT,现在找OEP.
在这里我按FLY大侠重开一个OD,shift+F9到程序运行后Ctrl+B在整个段块搜索Hex值：9D C3 E9找OEP的方法
没能成功,可能是我自己的操作问题,有成功经验的朋友希望介绍一下.
这里提供一个更快找themida保护程序OEP的方法,具体的原理是什么,我也不清楚,是一次偶然失误发现的(未必适
合所有程序)
在00939171处断下后,取消断点,ALT+M打开内存察看窗口，直接在代码段F2下断点。Shift+F9断在OEP处
0059F96C 55 push ebp-----------------OEP
0059F96D 8BEC mov ebp,esp
0059F96F 83C4 F0 add esp,-10
0059F972 53 push ebx
0059F973 B8 7CF15900 mov eax,yhds.0059F17C
0059F978 E8 8778E6FF call yhds.00407204
0059F97D 8B1D 183C5A00 mov ebx,dword ptr ds: ; yhds.005A4C38
0059F983 68 60FC5900 push yhds.0059FC60 ; ASCII "yyyy-MM-dd"
0059F988 6A 1F push 1F
0059F98A E8 157CE6FF call yhds.004075A4
0059F98F 50 push eax
0059F990 E8 877DE6FF call yhds.0040771C
0059F995 68 6CFC5900 push yhds.0059FC6C
到这里就可以用LordPE纠正大小后完整dump出来了,打开ImportREC F1.6, OEP:19F96C,自动搜索,获得有效指针
RAV:001A61F0, 大小:9CC,剪掉一个无效指针后修改dump出来的文件,修复后PEID0.94显示是Borland Delphi 6.0 - 7.0
编写的程序,修复后程序能正常运行.就是退出来时有出错提示(这个我就不知道怎么弄了,有请知道原因的朋友解
析一下).
