They won't necessarily know who it is, but every communication to and from
the internet has the IP address of the computer (which could be spoofed) and
the MAC address of the network card in the computer.  Chances are pretty
good that if you relied on the connection, you would provide more than
enough information about yourself to allow them to track you down quickly if
they wanted to.  I was hacked early last year over wireless.  I have learned
a lot about its weaknesses since then.
