Tornado2之Licence暴力破解

Tornado2是VxWorks开发调试工具,试用期为一个月.
超过试用期需要Licence支持,一个Licence需要$6000~$2000.买了软件,还要花钱,真是!@#$%^&*.

破解如下,希望对大家有用. :)

1.跟踪:
Tornado2的Licence程序主要运行在 ...\\host\\x86-win32\\bin\\tgtsvr.exe(...为Tornado2安装目录)

经过痛苦的跟踪过程,发现008B5236处为判断鉴权是否成功(该地址是在NT4.0+SP5.0中,可能系统
不一样,地址会不一样).跟踪过程就不写了吧.大家都是高手,我的跟踪过程写出来,大家会笑话的.
在跟踪过程中,我犯了很多愚蠢的错误,甚至死了很多次.后来发现都是可以避免的.

008B5236前有一系列CALL,是进行计算的.我曾跟进去,但发现是可能一个DLL.该公司用一个DLL进行运
算,我是不能通过算法破解了,只好暴力破解.

写破解代码可能对大家有一些作用,我将详细介绍.

2.破解思路:
该程序是通过加壳的,壳比较奇怪,我孤陋寡闻,没有见过.
我的想法是,我也可以在程序中加外壳,先获得控制修改代码,在原来壳结束时,作跳转到我的修改代码.
原来程序入口是00426DF5,原来壳的结束位置是00426F33.
1)将程序的入口地址改为00400300
mov ebx,426F33h
mov dword ptr [ebx],0FD93C8E9h
add ebx,4
mov byte ptr [ebx],0FFh
jmp 00426DF5
//以上为将00426F33改为jmp 1111.
1111.为自己代码地址
push ebx
mov ebx,426F33h
mov dword ptr [ebx],535BD0FFh
add ebx,4
mov byte ptr [ebx],81h
//以上为将00426F33改为
{
00426F33 FF D0 call eax
00426F35 5B pop ebx
00426F36 53 push ebx
00426F37 81 EB 2E 0D 00 00 sub ebx,0D2Eh
}
mov ebx,eax
add ebx,0E10Ah
mov dword ptr [ebx],7DEBC033h
//以上将程序改成鉴权成功
{
008B5236 33 C0 xor eax, eax
008B5238 EB 7D jmp 008B52B5
}
sub ebx, 0B7h//ebx=008B517F
mov word ptr [ebx],xxxx
//以上将程序改成98下跳到NT代码中执行
{
008B517F jmp 008B51C5
}
pop ebx
jmp 00426F33

外壳程序详细说明:
1)改变程序的入口地址到自己代码,在自己代码地方写跳转代码.该跳转代码将00426F33处程序改成jmp xxxx.
在该项操作中,需要取硬盘序列号,与jmp xxxx的机器码做xor运算.
取硬盘序列号使用LoadLibrary,GetProcAddress和GetVolumeInformationA.
其中LoadLibrary和GetProcAddress的函数地址需要查原来程序地址.
LoadLibrary = 00426FD0
GetProcAddress = 00426FCA
CALL xxxx = E8 + 偏移(4位)
2)在上面的jmp xxxx的xxxx地方处写代码,改变程序的运行路径.
需要有如下几个具体操作:
(1)将00426F33处还原
(2)改程序为98下也到NT代码中执行
(3)该程序为鉴权成功
3)需要的固定数据:
'KERNEL32.DLL', 0 //13 BYTES,LoadLibraryA用
'GetVolumeInformationA', 0 //22 BYTES,GetProcAddress用
'C:\', 0 //4 BYTES, GetVolumeInformationA用
总共0x27 = 39个BYTE
因此数据从400300开始,代码从00400330开始.

外壳程序实现:
1)将几个固定数据写进文件中:Raw Address = 0x300
00400300 'KERNEL32.DLL', 0
0040030D 'GetVolumeInformationA', 0
00400323 'C:\', 0
00400327 4 BYTE 数据
0040032B 0

2)写跳转代码,将00426F33处程序改成jmp xxxx, Raw Address = 0x330
00400330
00400330 55 push ebp
00400331 8B EC mov ebp,esp
00400333 83 EC 30 sub esp,70h ;实际使用0x22 BYTE
00400336 68 00 03 40 00 push 400300h ;'KERNEL32.DLL'
0040033B E8 90 6C 02 00 call 426FD0h;LoadLibraryA
00400341 68 0D 03 40 00 push 40030Dh ;'GetVolumeInformationA'
00400346 50 push eax ;hModule
00400347 E8 7F 6C 02 00 call 426FCAh;GetProcAddress
0040034B 6A 0A push 0Ah ;sizeof(lpFileSystemNameBuffer)
0040034D 8D 5D D8 lea ebx,[ebp-28h]
00400350 53 push ebx
00400351 8D 5D D0 lea ebx,[ebp-30h]
00400354 53 push ebx
00400355 8D 5D E4 lea ebx,[ebp-1Ch]
00400358 53 push ebx

00400362 53 push ebx
00400363 68 23 03 40 00 push 400323
00400368 FF D0 call eax
0040036A 8B 45 E8 mov eax,dword ptr [ebp-18h];VolumeSerialNumber
0040036D BB 27 03 40 00 mov ebx,400327h
00400372 33 03 xor eax,dword ptr [ebx]
00400374 BB 33 6F 42 00 mov ebx,426F33h
00400379 89 03 mov dword ptr [ebx],eax
0040037B 83 C3 04 add ebx,4
0040037E C6 03 FF mov byte ptr [ebx],0FFh;原来是E9 54 94 FD FF jmp 0040038D
00400381 83 C4 70 add esp,70h
00400384 8B E5 mov esp,ebp
00400386 5D pop ebp
00400387 E9 69 6A 02 00 jmp 00426DF5;跳转代码完成
0040038C
0040038C 53 push ebx
0040038D BB 33 6F 42 00 mov ebx,426F33h
00400392 C7 03 FF D0 5B 53 mov dword ptr [ebx],535BD0FFh
00400398 83 C3 04 add ebx,4
0040039B C6 03 81 mov byte ptr [ebx],81h
0040039E 8B D8 mov ebx,eax
004003A0 81 C3 0A E1 00 00 add ebx,0E10Ah
004003A6 C7 03 33 C0 EB 7D mov dword ptr [ebx],7DEBC033h
004003AC 81 EB B7 00 00 00 sub ebx,0B7h
004003B2 66 C7 03 EB 44 mov word ptr [ebx],44EBh
004003B7 5B pop ebx
004003B8 E9 76 6B 02 00 jmp 00426F33
004003BD

实验数据:
VolumeSerialNumber = 0x283a1709
E9 54 94 FD ^ VolumeSerialNumber = 0xd5ae43e0

其中的GetVolumeInformationA和变化数据,不是必须的.在写这一段代码时,不能将他放到原来的代码块中,
我曾经放过,但程序运行死了.可能有其他检查,但程序死的时候,堆栈已经被破坏了,我无法定位,不知哪位
能指点?

后记:
今年7月底破解该软件,原来想买给xx公司.不过后来失败了.这也是加GeVolumeInformatinA的原因.
前两天看到贵论坛上一篇文章,深有感触.破解应该是一个业余爱好吧,
希望能和大家交个朋友.

运行该Patch程序注意:
1.保证您已经安装好TornadoII,且TornadoII的应用程序没有运行.
2.运行程序patch.
3.选择TornadoII的安装路径.
4.将出现如图patch1OK.jpg所示,此时patch1已经成功,这时
patch.exe可以按否关闭,或者不关闭,直接运行TornadoII进行注
册.
注意:现在一定不能马上按"是"按钮.如果您按下,那么只好从第
二步重新来.
5.注册TornadoII将出现如register.jpg所示,此时您可以输入
任意的26个数字或字母,可以数字和字母混合.注册成功后,将
TornadoII的应用程序退出.
6.如果刚才您没有关闭patch.exe,现在直接按patch1OK.jpg所示的
"是"按钮,TornadoII将完全破解.如果您刚才将patch.exe推出了,
现在需要重新运行他.这一步成功的标志是patch2OK.jpg所示.
注意:如果您的操作系统是98/95,在第5步时将出现如98.jpg所示(98.jpg不能贴上来,见谅),
此时实际已经注册成功.您需要关闭TornadoII的注册程序,按照
第六步的指示做.如果您的操作系统是98/95,而且已经过期了,该
   Patch无能为力.只好重装系统和TII了.:(
