Tornado2之Licence暴力破解

Tornado2是VxWorks開發除錯工具,試用期為一個月.
超過試用期需要Licence支援,一個Licence需要$6000~$2000.買了軟體,還要花錢,真是!@#$%^&*.

破解如下,希望對大家有用. :)

1.跟蹤:
Tornado2的Licence程式主要執行在 ...\\host\\x86-win32\\bin\\tgtsvr.exe(...為Tornado2安裝目錄)

經過痛苦的跟蹤過程,發現008B5236處為判斷鑑權是否成功(該地址是在NT4.0+SP5.0中,可能系統
不一樣,地址會不一樣).跟蹤過程就不寫了吧.大家都是高手,我的跟蹤過程寫出來,大家會笑話的.
在跟蹤過程中,我犯了很多愚蠢的錯誤,甚至死了很多次.後來發現都是可以避免的.

008B5236前有一系列CALL,是進行計算的.我曾跟進去,但發現是可能一個DLL.該公司用一個DLL進行運
算,我是不能透過演算法破解了,只好暴力破解.

寫破解程式碼可能對大家有一些作用,我將詳細介紹.

2.破解思路:
該程式是透過加殼的,殼比較奇怪,我孤陋寡聞,沒有見過.
我的想法是,我也可以在程式中加外殼,先獲得控制修改程式碼,在原來殼結束時,作跳轉到我的修改程式碼.
原來程式入口是00426DF5,原來殼的結束位置是00426F33.
1)將程式的入口地址改為00400300
mov ebx,426F33h
mov dword ptr [ebx],0FD93C8E9h
add ebx,4
mov byte ptr [ebx],0FFh
jmp 00426DF5
//以上為將00426F33改為jmp 1111.
1111.為自己程式碼地址
push ebx
mov ebx,426F33h
mov dword ptr [ebx],535BD0FFh
add ebx,4
mov byte ptr [ebx],81h
//以上為將00426F33改為
{
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
//以上將程式改成鑑權成功
{
008B5236 33 C0 xor eax, eax
008B5238 EB 7D jmp 008B52B5
}
sub ebx, 0B7h//ebx=008B517F
mov word ptr [ebx],xxxx
//以上將程式改成98下跳到NT程式碼中執行
{
008B517F jmp 008B51C5
}
pop ebx
jmp 00426F33

外殼程式詳細說明:
1)改變程式的入口地址到自己程式碼,在自己程式碼地方寫跳轉程式碼.該跳轉程式碼將00426F33處程式改成jmp xxxx.
在該項操作中,需要取硬碟序列號,與jmp xxxx的機器碼做xor運算.
取硬碟序列號使用LoadLibrary,GetProcAddress和GetVolumeInformationA.
其中LoadLibrary和GetProcAddress的函式地址需要查原來程式地址.
LoadLibrary = 00426FD0
GetProcAddress = 00426FCA
CALL xxxx = E8 + 偏移(4位)
2)在上面的jmp xxxx的xxxx地方處寫程式碼,改變程式的執行路徑.
需要有如下幾個具體操作:
(1)將00426F33處還原
(2)改程式為98下也到NT程式碼中執行
(3)該程式為鑑權成功
3)需要的固定資料:
'KERNEL32.DLL', 0 //13 BYTES,LoadLibraryA用
'GetVolumeInformationA', 0 //22 BYTES,GetProcAddress用
'C:\', 0 //4 BYTES, GetVolumeInformationA用
總共0x27 = 39個BYTE
因此資料從400300開始,程式碼從00400330開始.

外殼程式實現:
1)將幾個固定資料寫進檔案中:Raw Address = 0x300
00400300 'KERNEL32.DLL', 0
0040030D 'GetVolumeInformationA', 0
00400323 'C:\', 0
00400327 4 BYTE 資料
0040032B 0

2)寫跳轉程式碼,將00426F33處程式改成jmp xxxx, Raw Address = 0x330
00400330
00400330 55 push ebp
00400331 8B EC mov ebp,esp
00400333 83 EC 30 sub esp,70h ;實際使用0x22 BYTE

實驗資料:
VolumeSerialNumber = 0x283a1709
E9 54 94 FD ^ VolumeSerialNumber = 0xd5ae43e0

其中的GetVolumeInformationA和變化資料,不是必須的.在寫這一段程式碼時,不能將他放到原來的程式碼塊中,
我曾經放過,但程式執行死了.可能有其他檢查,但程式死的時候,堆疊已經被破壞了,我無法定位,不知哪位
能指點?

後記:
今年7月底破解該軟體,原來想買給xx公司.不過後來失敗了.這也是加GeVolumeInformatinA的原因.
前兩天看到貴論壇上一篇文章,深有感觸.破解應該是一個業餘愛好吧,
希望能和大家交個朋友.

執行該Patch程式注意:
1.保證您已經安裝好TornadoII,且TornadoII的應用程式沒有執行.
2.執行程式patch.
3.選擇TornadoII的安裝路徑.
4.將出現如圖patch1OK.jpg所示,此時patch1已經成功,這時
patch.exe可以按否關閉,或者不關閉,直接執行TornadoII進行注
冊.
注意:現在一定不能馬上按"是"按鈕.如果您按下,那麼只好從第
二步重新來.
5.註冊TornadoII將出現如register.jpg所示,此時您可以輸入
任意的26個數字或字母,可以數字和字母混合.註冊成功後,將
TornadoII的應用程式退出.
6.如果剛才您沒有關閉patch.exe,現在直接按patch1OK.jpg所示的
"是"按鈕,TornadoII將完全破解.如果您剛才將patch.exe推出了,
現在需要重新執行他.這一步成功的標誌是patch2OK.jpg所示.
注意:如果您的作業系統是98/95,在第5步時將出現如98.jpg所示(98.jpg不能貼上來,見諒),
此時實際已經註冊成功.您需要關閉TornadoII的註冊程式,按照
第六步的指示做.如果您的作業系統是98/95,而且已經過期了,該
   Patch無能為力.只好重灌系統和TII了.:(
