According to forensic engineering consulting firm PT&C|LWG, cars today use between 20 and 70 computers, each with is own specialized use, that make up the overall functionality of the vehicle.
“Cars are vulnerable because they were never built with defenses in mind. If you take something that was designed to work in one set environment and you connect to it a much more hostile environment, you don’t have the right defenses in place. So of course it’s vulnerable. It’s like Bambi walking out of the forest into the field,” Jeff Williams, chief technology officer of the security firm Contrast Security, told Business Insider.
To find out which cars on the road today are the most vulnerable to hackers, PT&C|LWG put together a handy infographic. The most vulnerable cars are the 2014 Jeep Cherokee, the 2014 Infiniti Q35, 2015 Cadillac Escalade, the 2014 and 2010 Toyota Prius, and the 2014 Ford Fusion. (My primary car isn’t on the list, but I almost bought one that is.)
Their infographic also includes information on the least vulnerable cars, as well as what you can do to defend your vehicle from being hacked.
