Example: If I connect to Dell website and let them "detect" the laptop's service tag, I will need to allow the software to be installed.
I can imagine the same is possible if the program a user will install is programmed to detect a tag or serial #.
Even software's product key can be detected by other programs that a user allows to scan and detact.
I was wondering if a laptop's serial number can leak on internet. Dont really know how to explain better the question i.e if through "sniffing" a certain ip by a certain method one can find out what is the serial number.
Thanks for any pointers
