A SECURITY RESEARCHER kicked off a United Airlines flight last month after tweeting about security vulnerabilities in its system had previously taken control of an airplane and caused it to briefly fly sideways, according to an application for a search warrant filed by an FBI agent.
Chris Roberts, a security researcher with One World Labs, told the FBI agent during an interview in February that he had hacked the in-flight entertainment system, or IFE, on an airplane and overwrote code on the plane’s Thrust Management Computer while aboard the flight. He was able to issue a climb command and make the plane briefly change course, the document states.
“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,” FBI Special Agent Mark Hurley wrote in his warrant application (.pdf). “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.”
Hurley filed the search warrant application last month after Roberts was removed from a United Airlines flight from Chicago to Syracuse, New York, because he published a facetious tweet suggesting he might hack into the plane’s network.
Upon landing in Syracuse, two FBI agents and two local police officers escorted him from the plane and interrogated him for several hours. They also seized two laptop computers and several hard drives and USB sticks.
Although the agents did not have a warrant when they seized the devices, they told Roberts a warrant was pending. A media outlet in Canada obtained the application for the warrant today and published it online. The information outlined in the warrant application reveals a far more serious situation than Roberts has previously disclosed.
