How To Unlock A Car With A Text Message

Las Vegas (CNN) -- Don Bailey says he can unlock thousands of cars across the United States simply by sending a few texts from his Android phone.

And that's not even the scary part.

Bailey, a senior security consultant with iSEC Partners, said in an interview with CNN at the Black Hat security conference here at Caesars Palace that the same hack he has used to demonstrate unlocking and even starting a car via text message also could be used to attack industrial systems, the power grid and the water system.

"I could care less if I could unlock a car door," he said. "It's cool. It's sexy. But the same system is used to control phone, power, traffic systems. I think that's the real threat."
