Hacking Airplanes

Originally published in CNN.com, April 16, 2015

Imagine this: A terrorist hacks into a commercial airplane from the ground, takes over the controls from the pilots and flies the plane into the ground. It sounds like the plot of some “Die Hard” reboot, but it’s actually one of the possible scenarios outlined in a new Government Accountability Office report on security vulnerabilities in modern airplanes.

It’s certainly possible, but in the scheme of Internet risks I worry about, it’s not very high. I’m more worried about the more pedestrian attacks against more common Internet-connected devices. I’m more worried, for example, about a multination cyber arms race that stockpiles capabilities such as this, and prioritizes attack over defense in an effort to gain relative advantage. I worry about the democratization of cyberattack techniques, and who might have the capabilities currently reserved for nation-states. And I worry about a future a decade from now if these problems aren’t addressed.

First, the airplanes. The problem the GAO identifies is one computer security experts have talked about for years. Newer planes such as the Boeing 787 Dreamliner and the Airbus A350 and A380 have a single network that is used both by pilots to fly the plane and passengers for their Wi-Fi connections. The risk is that a hacker sitting in the back of the plane, or even one on the ground, could use the Wi-Fi connection to hack into the avionics and ...
