Two years ago, Charlie Miller and Chris Valasek pulled off a demonstration that shook the auto industry, remotely hacking a Jeep Cherokee via its internet connection to paralyze it on a highway. Since then, the two security researchers have been quietly working for Uber, helping the startup secure its experimental self-driving cars against exactly the sort of attack they proved was possible on a traditional one. Now, Miller has moved on, and he’s ready to broadcast a message to the automotive industry: Securing autonomous cars from hackers is a very difficult problem. It’s time to get serious about solving it.
Last month, Miller left Uber for a position at Chinese competitor Didi, a startup that’s just now beginning its own autonomous ridesharing project. In his first post-Uber interview, Miller talked to WIRED about what he learned in those 19 months at the company—namely that driverless taxis pose a security challenge that goes well beyond even those faced by the rest of the connected car industry.
