Dr. Charlie Miller is "one of the most technically proficient hackers on Earth," according to Foreign Policy. After receiving his PhD in Mathematics from the University of Notre Dame, Dr. Miller was a computer hacker for the National Security Agency for five years. Since that time he has worked for the Twitter information security team, as well as worked on the autonomous vehicle security team for Uber, Didi Chuxing, and currently Cruise Automation. He has won the "Super Bowl" of computer hacking, the annual Pwn2Own competition four times. Dr. Miller has found countless vulnerabilities in a number of Apple products including their laptops and phones. He was the first to remotely exploit the iPhone when it was released as well as the first Android phone when it was released (on the day it came out). Lately, Dr. Miller has spent considerable time in the field of automotive security. Dr. Miller demonstrated that a variety of Fiat Chrysler vehicles could be remotely hacked from anywhere in the country and he could control the radio, brakes, wipers, transmission, acceleration, and even the steering of the target vehicle. The demonstration of these vulnerabilities led to the recall of 1.4 million vehicles.
