Hundreds of planes flying commercially today could be vulnerable to having their onboard computers hacked and remotely taken over by someone using the plane's passenger Wi-Fi network, or even by someone on the ground, according to a new report from the Government Accountability Office. One of the authors of the report, Gerald Dillingham, told CNN the planes include the Boeing 787 Dreamliner, the Airbus A350 and A380 aircraft, and all have advanced cockpits that are wired into the same Wi-Fi system used by passengers.
