Hackers could use in-flight entertainment to take control of airplane

Flaw could put passenger safety at risk on multiple airlines

A vulnerability found in an in-flight entertainment system could enable hackers to hijack flight systems or even take control of a plane, a security researcher has warned.

Ruben Santamarta, principle security consultant at IOActive, found that an in-flight system from Panasonic Avionics could be hacked with its on-board displays used to display any information a hacker wanted. It could also be used to change cabin lighting and send announcements over the airplane communications channel.

According to reports by the Telegraph, Santamarta said all of this would be "an unsettling experience for passengers".

The system is currently in use by airlines such as Qatar, Scandinavian, Singapore, United, and Virgin, to name a few. He added that in some circumstances, credit card details of frequent flyers stored in an automatic payment system could be accessed and it was possible the vulnerability could be used to access aircraft controls.

"I don't believe these systems can resist solid attacks from skilled malicious actors," he told the newspaper. "This only depends on the attacker's determination and intentions, from a technical perspective it's totally feasible."

Santamarta said that it would be up to the airlines to limit access in case of a breach. He added that in-flight entertainment systems should never be linked to aircraft controls and isolating critical systems was vital to protect against such attacks.

The researcher said he had alerted Panasonic to the problems back in March 2015, but it isn't clear what action the company has taken to fix the flaw. IT Pro contacted the firm for comment, but hadn't received a response at the time of publication.

Stephen Gates, chief research intelligence analyst at NSFOCUS, told IT Pro that in the light of this research, physical separation between in-flight entertainment systems and aircraft control systems could never be more important.

"As airlines continue to add new customer-based entertainment and information technologies, airlines need to ensure that an impenetrable barrier is in place protecting aircraft control systems," he said.

Mike Ahmadi, global director of critical systems security at Synopsys, told IT Pro that any system that gets the attention of the hacking/research community will eventually be found vulnerable. 

"There are literally an infinite number of ways to compromise any system.  Organisations need to constantly monitor and test their systems in order to keep up with security issues.  Moreover, organisations should assume compromise will happen and plan accordingly," he said.
