In 2015, Wired reporter Andy Greenberg asked Charlie Miller and Chris Valasek to show him something interesting. Andy completely forgot what hackers consider “interesting” and they famously shut down the engine of a Jeep Cherokee while he was driving on the highway.

This talk aims to address the new and old problems in four frontiers of vehicle security and where security experts can make a difference.
