                                             THE ESSAY

this tutorial was written for newbies, so i'll try to explain everything in details.
if u found something that is not explained well, thats cuz i'm a newbie myself!
BTW...when i write something like "d eax" or something like that i mean without the quotes.

        SO...THINK U READY?!? GOOD!!! SRART READING!!!
-------------------------------------------------------------------------

STEP 1: go to the registration part, enter your favorite name, company, and your fake reg number(its recommanded that u enter a number that is easy to remember ;)
my reg info was:
NAME: Blackgh0st
COMPANY: BLACKGH0ST
CODE: 12345
now..open softice (CTRL+D) and set a breakpoint on execution, this time it will be "getwindowtexta"  so type "bpx getwindowtexta" and enter. now close softice (CTRL+D/F5) and go to the program, click ok and u get kicked into softice... ;)

STEP 2: in softice u nedd to press "F5" two times (cuz there are three fields in the registration part and we are in the first now) now press "F12" to step out of the DLL, and u should be here:

:0044B3B6   MOV    ECX, [ebp+10]
:0044B3B9   PUSH   FF
:0044B3BB   CALL   00444CBF
:0044B3C0   JMP    0044B3C

now start tracing with F10 untill u get here:

0042691F    MOV    [EBP-18], EAX <---our fake number (in eax) moves to [EBP-18]   
00426922    CMP    [ECX+000004DB], BL
00426928    JZ     00426B40015F
0042692E    CMP    EAX, EBX
00426930    MOV    ESI, 0047DA00
00426935    JZ     00426A41
0042693B    PUSH   DWORD PTR [EDI+000000D5]
00426941    CALL   004272DC
00426946    CMP    [EBP-18], EAX <----we know that our fake serial is [ebp-18] and it is compared to something, what can it be compared to? right, the real serial! for me it was: 4305010508
CONGRATULATIONS! U JUST CRACKED TELEPORT PRO 1.29 BY YOURSELF! (not really, i helped u!)
