This presentation will explain and show how to remotely attack and take control of some aircraft on-board systems, exposing some of the results of my five years research on the aviation security field. Following the same approach of past presentations, and in order to present a feasible attack scenario, I will follow the full attack methodology against an aircraft by exploiting aviation protocols weaknesses and avionic systems vulnerabilities. The complete attack will be accomplished remotely, without needing physical access to the target aircraft at any time, and real avionics systems (SW and sometimes HW) will be used. As an improved version of my past presentations, more realistic demos will be shown, better research and attack environments presented and new attack vectors and target systems will be exposed that overcome most of the limitations of previous attacks.
