Boeing's new 787 Dreamliner passenger jet could contain a "serious security vulnerability" according to the U.S. Federal Aviation Administration (Via Wired).
"Because of this new passenger connectivity, the proposed data-network design and integration may result in security vulnerabilities from intentional or unintentional corruption of data and systems critical to the safety and maintenance of the airplane," the FAA adds.
This means that a passenger could potentially break in the airplane's internal network and take control of the plane's systems.
A Boeing spokeswoman told Wired that passenger and control networks are only loosely connected but Boeing has already taken steps to make sure that the concerns of the FAA, which oversees air space in the US, are resolved.
More than 800 units of the airplane have been sold but until the FAA is fully confident that the plane is safe to fly, it will block the 777 deployment.
Mark Loveless, a network security analyst who presented a conference talk last year on Hacking the Friendly Skies commented on the announcement saying "This is serious, This isn’t a desktop computer. It's controlling the systems that are keeping people from plunging to their deaths. So I hope they are really thinking about how to get this right."
