一、脱壳
PEiD查壳:UPX 0.89.6 - 1.02 / 1.05 - 1.24 -> Markus & Laszlo
1.用脱壳机。
2.手脱:F8+ESP定律+F8 到达OEP,没有自效验。
脱壳后PEiD查:Borland Delphi 6.0 - 7.0
二、追码
OD 载入程序查找字串参考,找到:“register succeed, enjoy!”双击来到:004B7BB8处,向上在004B791B处下断,F9运行程序。在注册框里填用户名:wzwgpa(大于5、小于等于40) 注册码:123-4567-891(固定格式) 点“OK”

三、追码分析
1.用户名、注册码输入注册框时,非数字字符程序自动转成大写,用户名位数大于5、小于等于40,注册码:***-****-***(固定格式)
2.用户名与程序名连接(含2个空格),ND5加密
WZWGPA --> WZWGPAFlash ScreenSaver Maker --> MD5 --> ab88f3f20059220e0a05494a2cfb6877
3.注册码第4位必须是0…9之间的数,根据注册码第4位数值查表得到指向MD5加密字符的定位值。
1234567891 --> 4 --> 10、1、16、9、1D --> e、a、9、0、6
16、1、22、9、29
4.e、a、9、0、6 成为注册码中的第2、3、6、7、9位。
我的用户名:wzwgpa
注册码:*ea-4*90-*6* (*为任意数)
注册信息保存在注册表:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ShellSaver
