COIN-SIZED DEVICE CAN HIJACK BOEING 737

Researchers successfully inserted a coin-sized device into an exterior port and redirected the plane's autopilot or sabotaged its flight plan during the proof-of-concept attack. The vulnerability highlights physical security gaps in aircraft design. While the attack demands direct access to the plane's exterior—limiting real-world risk—it raises questions about airport perimeter security and maintenance procedures. Boeing has not yet publicly commented on the findings. The research underscores ongoing concerns about aircraft cybersecurity as modern planes rely increasingly on networked systems. Security experts recommend aircraft manufacturers review external port accessibility and implement additional authentication measures for critical systems. Aviation authorities may need to strengthen physical security protocols at maintenance facilities and hangars where aircraft remain parked.
