Brad Haines (RenderMan) CISSP, is a Whitehat by trade, Blackhat by fashion, who presented this talk at DEFCON 20. For those of you unfamiliar with him, RenderMan has a history of hacking RF who’s rumored to be a member of the Church of WiFi. In this presentation he turns his attention to ADS-B (Automatic Dependent Surveillance-Broadcast), a common technology installed or being installed on a vast majority of commercial airliners that involves an unencrypted and unauthenticated radio broadcast. He explores the system’s features and weaknesses, noting what can happen when security is not built in from the beginning. He hopes that this serves tospur more research and investigation into this field.
