工具:PW32GOLD,TRW1.23。
过程:
先用PW32反汇编,查找“你输入的用户注册码不正确”。
来到如下地址:
:004B5026 8B83E4020000 mov eax, dword ptr [ebx+000002E4]
:004B502C E847EDF7FF call 00433D78
:004B5031 8B55EC mov edx, dword ptr [ebp-14]
:004B5034 58 pop eax
:004B5035 E8E2F0F4FF call 0040411C------->比较
:004B503A 7416 je 004B5052 ------->不跳即死
* Possible StringData Ref from Code Obj ->"您输入的用户注册码不正确。"

:004B503C B8B8524B00 mov eax, 004B52B8
:004B5041 E85A46FAFF call 004596A0
:004B5046 8BC3 mov eax, ebx
:004B5048 E87B99F9FF call 0044E9C8
:004B504D E9DE010000 jmp 004B5230
* Referenced by a (U)nconditional or (C)onditional Jump at Address:
|:004B503A(C)

:004B5052 8D55E8 lea edx, dword ptr [ebp-18]
.....................................................................................
进比较CALL
:0040411C 53 push ebx
:0040411D 56 push esi
:0040411E 57 push edi
:0040411F 89C6 mov esi, eax---->真的注册码(D EAX)
:00404121 89D7 mov edi, edx---->假的注册码(D EDX)
:00404123 39D0 cmp eax, edx---->比较
:00404125 0F848F000000 je 004041BA
......................................................................................
运行程序,打开注册框,注册名填crackboy,注册码填123456.
先不要按确定,运行TRW,BPX 0040411F,F5回到程序,按确定被拦下,
这时下D EAX 可看到真的注册码023690261367041454。回到程序用真注册码注册成功!
整理注册码如下:
注册名:crackboy
注册码:023690261367041454
