what is the best way to crack s/w that acccess the web to check s/n?

hello all

i have been trying a few ways to crack some s/w that uses the web to check s/n if i try to bypass this then i can't get any updates..it will let you get 4 free updates before it asks to pay...it checks the s/n (which is diff on each p.c you install it on) via the web? can this be cracked or no?

there is a section to enter a s/n that they send to you...it seems like the download updated button is disable

[EDIT JMI: Chad there is an Edit Button on the Posts. There is NO NEED to start a new post to ADD to your last one.]

thanks

Have you tried to use a network protocol analyzer - ethereal for example - to capture the data that it tries to send to the remote site?
Maybe you can get some clues or try to see what it expects back from the server.
Do you have an URL of that program?

yes the url is

h**p://www.numaxcreator.com/Uploads/NumaxCreator%20v7.x%20Setup.exe

thanks

p.s sorry about that JMI

[EDIT JMI: No big deal. Just trying to save some room in the database.]

"...it checks the s/n (which is diff on each p.c you install it on) via the web? can this be cracked or no?

I guess this is a kind of protection that we'll start to see more and more and it's obvious that nobody feels safe studying an app connected to the net. I am not sure but i remember that DAMN made some kind of "proxy"(?) to emulate some protection based on this...not sure.

yea i have tried a few diff ways to crack this so far no go but i'am still learning this stuff...i hope someone out there thinks of a way to get around this....

thanks

well, Load the EXE or DLL into IDA...

check out the imports.. usually imports are used to connect to the internet and check a sn :>
if not, then check out the exports, some other functions that the exe has..

id just disable the Net connect, and assemble the proper code for it to be registered.. :>

i don't know if could be useful, i've seen the new trillian web check protection yesterday and this program use these imports of Wininet.dll

HttpOpenRequestA
InternetCloseHandle
InternetConnectA
HttpSendRequestA
InternetQueryDataAvailable
InternetReadFile
InternetQueryOptionA
InternetSetOptionA
InternetOpenA
HttpQueryInfoA

so look fro strange names into imports.. maybe your program uses stupid functicon like these bye

WSAAccept
WSAConnect
WSARecv
WSARecvDisconnect
WSASend
WSASendDisconnect
WSASocketA

"Personally I don't like the style of "press F8, make a dump using PETools, fix the offset at...". I prefer the way of logic explaination (not tutorial) and ideas suggestion"

Yeah,,i agree completely with these words and also, if possible, ideas suggestion with a little rhetoric digressions in the old +Orc's oratorian style. Ahh...i'm sure i'm not the only one who misses so much that old texts.....Sorry.
