Pure Hacking CTO Ty Miller said "With literally thousands of machines or devices accessible, I only needed to hack one [during a scheduled penetration test of an airline network] to begin escalating my privileges that resulted in complete compromise the airline's environment. This included capturing credit cards, documents, plans, communications and databases."
He added that "[future] cyber-threats will be more diversified and take the form of multi-stage and multi-dimensional attacks that utilise and target a variety of attack tools and technologies. For example, the latest generation of web worms uses a variety of different 0-day exploits, propagation methods, and payloads to inflict physical damage." Yet the aviation sector implicitly relies on systems that require a highly secure environment.
"The stereotypical Die Hard 2 airport attack where aircraft controls can be taken over is no longer just a movie script. It's an actual reality."
