Adam Wirth (SimonJ) is a wireless communications software and systems engineer with more than 15 years professional experience. He has spent the majority of his career working on esoteric wireless communications for even-more-esoteric purposes, including RF emitter geolocation. He won both the foxhunting challenges in the WiFi Pentathlon at DEFCON 21 using nothing but an unrooted Android tablet, and wants more of a challenge this year.
