Don't take the claims at face value
While I am inclined to believe that the electronics in an aircraft can be hacked, I would not take this guy's claims as being 100% legitimate. If he's a white hat gone astray then he should be able to demonstrate his skills in taking control of the aircraft electronic with the plane on the ground. If he can in fact do this then all aircraft makers need to get very serious about hardening their electronic systems.
