Define area: Set detailed filters related to the airplane, for example activate something when a plane is in the area of X kilometers or when it starts flying on a predefined altitude.
Visit ground: Crash the airplane.
Kiss off: Remove itself from the system.
Be punckish: A theatric way of alerting the pilots that something is seriously wrong - lights start flashing and alarms start buzzing.
By showing a sample scenario of a drunk pilot flying over Berlin, Teso mentioned that the Android application also uses the benefits of the accelerometer and therefore a remote attacker can transform the motion of its smartphone into physical changes in the plane's movement.

It's amazing to discover that aviation - an industry where safety is of vital importance and every physical element has one or even two fail-safe mechanisms - is failing to secure the onboard computer, the heart and brain of the plane.

Teso has not shared too many details about the tools he used to effect the attack, as the vulnerabilities have yet to be fixed. He says that he was pleasantly surprised by the reaction of the industry to his research and discoveries, as the companies didn't try to deny the existence of the problems and have vowed to aid him in his research.

He says that older, legacy systems harking back to the 1970s will be difficult, if not impossible, to fix, but that modern ones will easily be updated with patched and modified firmware and software.
