Hackers on a Plane

Posted April 11, 2013    BeyondTrust Research Team

If I were cast in a movie in which the plotline centered on a person on a plane maliciously controlling the entire 550MPH Pringles Can via smartphone, I’d demand the movie be called ‘Hackers on a Plane’, just so people knew what they were getting into when purchasing their matinee ticket. However, this seemingly far-fetched plotline is now a reality via the culmination of three years of flight management systems (FMS) InfoSec research.

This year at Hack in the Box Amsterdam, N.Runs’ Hugo Teso, who happens to be a commercial pilot as well as a security researcher, demonstrated the capability to completely control an aircraft’s trajectory via spoofed communications from the ground. By leveraging known weaknesses in ADS-B (Automated Dependent Surveillance-Broadcast) and ACARS (Aircraft Communications Addressing and Reporting System), Teso could leverage vulnerabilities within flight management systems, manufactured by Honeywell and Thales, among others, on an aircraft to make the aircraft change heading, angle, and speed. However, there is catch: no hacking took place on actual aircraft (which would be quite dangerous), but merely PC-based flight training and simulation software.

According to European Aviation Safety Administration (EASA), as well as a spokesperson from Honeywell, there are significant differences between PC-based FMS training software, and FMS deployed in aircraft. FMS used in aircraft apparently contain “overwriting protection and redundancies” that supposedly provide some mitigation against exploitation, but this does not mean that embedded systems are not vulnerable to similar flaws. More importantly, this latest research (and the latest round of hype from popular media outlets) does not address the most glaring flaws of all: the lack of authentication concerning communication from the ground to aircraft. If the embedded FMS systems were developed over the last 30 years, “… following strict guidance and best practices that include … particular robustness”, then why did no one tackle the fairly obvious issue concerning how we talk to planes currently?

“…a network is only as secure as its weakest link…”

As mentioned in our CTO Marc Maiffret’s recent op-ed piece in the New York Times, we “typically do not hear about how attackers were able to put a virus or other malware on a system in the first place” but in this situation, we know. Research has been released over the past few years detailing how insecure ADS-B and ACARS is, but no governing body has addressed it directly, beyond the slow deployment of Aeronautical Telecommunications Network, which is the secure replacement for ACARS. Do we really have to wait for some tragedy to occur before we realize that security was not a fundamental part of the design process?

    You realize there’s an organization called Hackers on a Plane right?

Are Your Data Security Efforts Focused in the Right Area?

Posted January 28, 2015    Scott Lang

Vormetric Data Security recently released an insider threat report, with research conducted by HarrisPoll and analyzed by Ovum. Based on the survey responses, it is apparent that there is still a great deal of insecurity over data. However, the results also show that there may be misplaced investments to address those insecurities. I will explain…

GHOST Vulnerability…Scary Indeed

Posted January 28, 2015    BeyondTrust Research Team

A vulnerability discovered by Qualys security researchers has surfaced within the GNU C Library that affects virtually all Linux operating systems. The vulnerability lies within the various gethostbyname*() functions and, as such, has been dubbed “GHOST.” GHOST is particularly nasty considering remote, arbitrary code execution can be achieved. In an effort to avoid taxing DNS lookups, glibc developers introduced…

Your New Years Resolution: Controlling Privileged Users

Posted January 27, 2015    Dave Shackleford

Is 2015 the year you get a better handle on security? The news last year was grim – so much so, in fact, that many in the information security community despaired a bit. Really, the end-of-the-year infosec cocktail parties were a bit glum. OK, let’s be honest, infosec cocktail parties are usually not that wild…
