Hackers, FAA Disagree Over ADS-B Vulnerability

The ADS-B system that is the cornerstone of the FAA’s NextGen ATC modernization plan is at risk of serious security breaches, according to Brad Haines (aka RenderMan), a hacker and network security consultant who is worried about ADS-B vulnerabilities. Haines outlined his concerns during a presentation he gave at the recent DefCon 20 hacker conference in Las Vegas, explaining that ADS-B signals are unauthenticated and unencrypted, and “spoofing” or inserting a fake aircraft into the ADS-B system is easy.

Haines and hacker Nick Foster demonstrated this by spoofing a fake aircraft into simulated San Francisco airspace, using the Flight Gear simulator program. He said spoofing a target into the real ADS-B system would be a simple matter of transmitting the signal on the ADS-B frequencies.
