Just been reading this mornings paper here.
It seems there are people here in town that like to drive around town looking for un-secured Wi-Fi signals to latch onto, to download all sorts of things.
A couple of people have been caught out, the hard way with huge ISP bills. shocked
The police are now involved.

Personally I can't say I have a lot of sympathy for these people, I mean, how difficult is it to secure a wireless router these days?
Most set-up software makes it a cinch to secure your wifi signal.
However some people are of the mind that it's just too hard, if they bothered to read the documentation that came with the thing, they'd not be out of pocket.

Sure, these punks shouldn't be doing this sort of thing (which is tantamount to theft), but would you leave your house unlocked 24/7?
