Salo2112 writes with a followup to a story from April in which a security researcher was pulled off a plane by FBI agents seemingly over a tweet referencing a security weakness in one of the plane's systems. At the time, the FBI insisted he had actually tampered with core systems on an earlier flight, and now we have details. The FBI's search warrant application (PDF) alleges that the researcher, Chris Roberts, not only hacked the in-flight entertainment system, but also accessed the Thrust Management Computer and issued a climb command. "He stated that he thereby caused one of the airplane engines to climb resulting in a lateral or sideways movement of the plane during one of these flights. He also stated that he used Vortex software after comprising/exploiting or ‘hacking’ the airplane’s networks. He used the software to monitor traffic from the cockpit system." Roberts says the FBI has presented his statements out of their proper context.
