You might call 2015 "The Summer of Car Hacking," with multiple exploits presented and the first-ever cybersecurity-related vehicle recall. It grabbed the attention of manufacturers, regulators, lawmakers, and consumers. But the Summer of Car Hacking didn't just happen out of nowhere. In this talk, I'll cover some of the history of car hacking, including some of our earlier results, including taking over a 2009 sedan through cellular connections, Bluetooth, Windows Media files, and infected dealer tools. I'll also talk about more recent work where we compromised aftermarket insurance dongles to hijack control of vehicles. I'll discuss how a blind-sighted industry began to take security seriously, and cover where I think the industry is headed.
