Wired:
IN 2013, WHEN University of Birmingham computer scientist Flavio Garcia and a team of researchers were preparing to reveal a vulnerability that allowed them to start the ignition of millions of Volkswagen cars and drive them off without a key, they were hit with a lawsuit that delayed the publication of their research for two years. But that experience doesn’t seem to have deterred Garcia and his colleagues from probing more of VW’s flaws: Now, a year after that hack was finally publicized, Garcia and a new team of researchers are back with another paper that shows how Volkswagen left not only its ignition vulnerable but the keyless entry system that unlocks the vehicle’s doors, too. And this time, they say, the flaw applies to practically every car Volkswagen has sold since 1995.
“It’s a bit worrying to see security techniques from the 1990s used in new vehicles,” says Garcia. “If we want to have secure, autonomous, interconnected vehicles, that has to change.”
