Charlie Miller (@0xcharlie) is a security engineer at Twitter. Back when he still had time to research, he was the first with a public remote exploit for both the iPhone and the G1 Android phone. He is a four time winner of the CanSecWest Pwn2Own competition. He has authored three information security books and holds a PhD from the University of Notre Dame. Charlie spends his free time trying to get back together with Apple, but sadly they still list their relationship status as "It's complicated".
