New York Times story (temporarily viewable with free registration): Can a Virus Hitch a Ride in Your Car? What if viruses, worms or other forms of malware penetrated the computers that control ever more crucial functions in the car? Could you find yourself at the wheel of two tons of rolling steel that has malevolent code coursing through its electronic veins? That frightening prospect has had Internet message boards buzzing this year, amid rumors that a virus had infected Lexus cars and S.U.V.'s. The virus supposedly entered the cars over the Bluetooth wireless link that lets drivers use their cellphones to carry on hands-free conversations through the cars' microphones and speakers. ... The Lexus tale, based on murky reporting and a speculative statement by Kaspersky Labs, a Moscow antivirus company, seems to have been unfounded. "Lexus and its parent companies, Toyota Motor Sales USA Inc. and Toyota Motor Corporation in Japan, have investigated this rumor," the carmaker said in a statement last month, "and have determined it to be without foundation." But the question lingers: Could a car be infected by a virus passed along from, say, your cellphone or hand-held computer? Or worse, by a hacker with a Bluetooth device within range of the car's antennas?Even without Bluetooth, cars are increasingly built with built-in computers, from fuel mixing to braking systems to GPS navigation to OnStar. So this particular story was apparently not true, but here's what I wonder: How vulnerable are any of these systems? Is it just a matter of time before one of these rumored "carhackings" turns out to be real?
