Coin-Sized Device Can Hijack Boeing 737 Flight Systems in Under a Minute

Researchers from UC San Diego and Oberlin College demonstrated a proof-of-concept attack using a coin-sized device that can hijack critical flight systems in Boeing 737 aircraft. By plugging the device into a hardwired communications channel, attackers can manipulate flight data, potentially redirecting flights or causing unsafe takeoff conditions. The attack requires physical access to the aircraft, which can be gained during maintenance or while parked at a gate. The vulnerability was disclosed to Boeing in 2020, and the company has since collaborated with the researchers to evaluate security measures. The Boeing 737 is widely used, with approximately 8,000 units in service globally. Boeing stated that the research does not pose an immediate threat to operational safety, but they take security concerns seriously and appreciate responsible disclosure.

Key Points: • A coin-sized device can hijack Boeing 737 flight systems in under 60 seconds. • The attack requires physical access to the aircraft's communication ports. • Boeing has acknowledged the vulnerability and collaborated with researchers since 2020.
