You see, the average hacker is only looking for a place from which to launch attacks, store warez (pirated software) and play games. It doesn't matter to them if you see an IP address and think networked printer. They see ram and disk space. They don't care if it's a printer or a garage door opener. If it's running Windows, it's definitely fresh meat. It only gets better when it's your grandmother's Windows 98 machine that she leaves online over her dialup modem every night when she falls asleep in front of CSI:Sheboygan. (I know you've always wondered why her phone was busy at the oddest times.)
