Hi all,
I am able to sniff Serial of one program
But even after a 'Registration Succeded' MsgBox, There is no Success.

My Findings are :
1)There is a separate User-ID for each Computer.

2)A file *****.dat is created.The real Serial No: is Encrypted and stored here.
3)The File is packed with ASpack (Version???)

Seems more Protection Mechanisms are there.
Any body had the idea?

Perhaps the program is connecting to a remote server to validate the serial number you fished? If you use a good firewall it should tell you if the program is trying to connect to a remote auth server. Just an idea.

Hi zkhan123,

Notice some protections make their serial generation routines depend on a program integrity check. This way, if you set breakpoints in the code, the generated serial you fish will be valid and recorded, but as long as you restart the program and you change or remove the breakpoints, the serial won't pass the initial validation and it will fail.

You'd better study the initial validation process, since that is the really important one which will lead to you target being set to "registered mode", even though it may use the same way to protect against tampering.

Please let us know of your progressions.
Good luck!
