【软件大小】2.44M
【原版下载】http://www.skycn.com
【保护方式】注册码
【软件简介】命中乐透彩软件综合目前 网络上最热门的彩票分析技术,运用各种数学方法对彩票的历史开奖号码进行复杂的整理、统计、运算,得到更具分析性的数据,提供了多种投注方式,通过多种常用的过滤方法(同一种过滤方法可以在不同的转换数据分析中使用8次)高比例的对投注组合进行优化, 最大限度的减少了彩民的投注数量,使投入资金减少95%以上,是长期分析乐透型彩票的利器。

【破解声明】
------------------------------------------------------------------------
【破解过程】首先用PEID查壳,发现无壳,是用Microsoft Visual Basic 5.0 / 6.0写的。
用od载入,F9运行。机器码为“HWDWCANMF776078”在注册处填入“123123123”下万能断点程序停在77D3352D:
77D3352DF3:A5 REP MOVS DWORD PTR ES:[EDI],DWORD PTR DS>;停在这里
77D3352F8BC8MOV ECX,EAX
77D3353183E1 03 AND ECX,3
77D33534F3:A4 REP MOVS BYTE PTR ES:[EDI],BYTE PTR DS:[>

77D3353F5BPOP EBX
77D335405DPOP EBP
77D33541C2 1000 RETN 10

Alt+F9回到程序领空:
0062137C .DBE2FCLEX ;回到这里,一路F8
0062137E .8985 B4FEFFFF MOV DWORD PTR SS:[EBP-14C],EAX

0062138B .7D 23 JGE SHORT MzLotto.006213B0
0062138D .68 A0000000 PUSH 0A0


来到这里:
00621411 .E8 8A5ADEFF CALL <JMP.&MSVBVM60.__vbaLenBstr>;获取假码长度
00621416 .83F8 0F CMP EAX,0F
00621419 .0F84 9F000000 JE MzLotto.006214BE;与15比较,不等就注册码错误

00621426 .C785 7CFFFFFF>MOV DWORD PTR SS:[EBP-84],0A

00621437 .C745 8C 0A000>MOV DWORD PTR SS:[EBP-74],0A
由此知道注册码为15位。
Ctrl+F2重新载入程序输入15位注册码“1234567890abcde”,同样的方法在00621419处跳转,然后继续F8.

一个大循环,循环15次,依次对转化后的注册码进行处理,不是很重要,我只取了头尾部分:

这个循环是算法,依次取机器码和假注册码进行计算。
算法清楚了:
注册码只能为数字和字母,依次取出机器码a和注册码b每一位,
(48+a-37(或30)-位置数-(b-37(或30)))mod24+37(或30)
循环15次得到新的一组15位的数,结果保存在 EAX
退出循环,往下看:

看来要使机器码和注册码运算后的结果为零才能注册成功。
这里计算很复杂,本来想爆破把00621AE0 的JNZ 改为JZ 发现行不通。
后来不断尝试发现机器码依次往后数它所在的位置数得到的数与它运算结果恰好为零,它是按
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ排序的。

最后用“HWDWCANMF776078”和“IYG0HGUUOHIIDLN”注册成功。

你说本地验证.我还以为有网络验证的呢....
不错这算法挺绕的...
