The last place anyone would expect to face a computer security attack is on the windshield of their car in the form of a parking ticket.

But that's the latest -- and intensely clever -- way that hackers are attempting to goad people into visiting infected websites and willingly install malware on their machines.

The scam is instantly clever once you hear how it works: Hackers print up phony "PARKING VIOLATION" notices and plaster them on cars parked on the street. The phony ticket directs the car's owner to visit a certain website, and of course the website in question (which largely seems to comprise of photos of badly parked cars) is a hack site which attempts to install malware on your PC.

Essentially what we have here is a phishing attack that takes place in the real world instead of via email. The use of fliers on parked cars is what's truly ingenious: A similar attack sent via postal mail would probably have minimal effect, but people are incredibly protective of their cars, and I imagine these windshield fliers will actually have a pretty good percentage of people typing in the URLs typed on them.
