  Programs like NetBus and Back Orifice make this pretty simple.  The 
NetBus web page even also provides a tool for unmasking those who've 
set ICQ to attempt to hide their IP address.

  [Dial-up users are generally poor targets for hackers, because 
they're only connected intermittently, and often have dynamic IP 
addresses which vary from one connection to the next.
  ICQ, however, voids this apparent safety, because internally it has 
to broadcast essentially "I'm on NOW, at this IP!"....]
