ISIL cyberattack on airplane unlikely, federal intelligence analysts reported

OTTAWA - The prospect of a terrorist cyberattack on an airplane struck federal intelligence analysts as more pie-in-the-sky than a real possibility, newly released documents show.

The modern airliner's reliance on digital flight-control systems make some believe planes are vulnerable to malware that could be uploaded either online or through a direct connection, notes an assessment by Transport Canada's security intelligence assessment branch.

Although there are no confirmed cases of malware being used to hijack an aircraft's flight systems, it is "theoretically possible to do so," says the November 2014 assessment, recently obtained under the Access to Information Act.

"Changing flight control settings at critical times (landing or takeoff) could be catastrophic," the note allowed, but added: "The likelihood of such an event is assessed as very low."
