Anawave Web Snake 1.23

Type       : Offline Explorer
Protection : Serial
Tech       : Patching


Crack : Finding S/N for this program is difficult.
This program tries to fool crackers by generating worng S/N.
But by patching it can be cracked.Finding the place to patch
is also little harder,we have to trace through MFC DLL.Other
wise we will never reach that code :)

Hunt from starting ...

0x4495F2 CALL 0x4498E0    >> INSIDE WEB SANKE
            | | |
            vvvvv
         0x4498F0 CALL 0x44994E
                     | | |
                     vvvvv
                  0x5F40999C CALL [EAX+58]  >> INSIDE MFC

After tracing through MFC we will reach :

0x4219D1 CALL [0x45FC1C]   >> GOING TO ENTER IN TO _ANALIB.DLL

Inside _ANALIB.DLL

0x10007352 CALL 0x10007670 >> MAIN CHECK
