U.S. news media went bonkers a couple of weeks ago when information security researchers, in conjunction with a journalist from Wired, demonstrated how they could remotely access a Jeep Cherokee and take control of various functions, including its engine, steering, and braking. The hack exploits the fact that many cars and trucks today interface with the Internet in some fashion, either directly or via other devices that connect to them (like a smartphone).
That hack targets vehicles on a one-to-one basis, and it is not the first of its kind. But what if you could broadcast an exploit to multiple vehicles at once? Turns out this is possible, too. Researchers in the U.K. say they can transmit code within a DAB digital radio signal that provides control of critical vehicle systems.
