![]() These vulnerabilities were found by security researcher Sam Curry who conducted in-depth research into the security loopholes of the automotive industry along with researchers Neiko Rivera, Brett Buerhaus, Maik Robert, Ian Carroll, Justin Rhinehart, and Shubham Shah. Millions of vehicles belonging to 16 different manufacturers had completely exposed API vulnerabilities which could be abused to unlock, start, and track cars while also impacting the privacy of the vehicle owners.
