This Coin-Sized Device Can Hack a Boeing 737

Academic researchers have demonstrated a practical physical-access attack vector against Boeing 737s using a coin-sized device costing under $100 that can manipulate autopilot systems and falsify critical flight data to pilots—exposing a significant blind spot in aviation cybersecurity. While Boeing downplays the real-world risk, the researchers emphasize the need for immediate operational security improvements (such as port access controls) and long-term redesigns of aircraft component security. This vulnerability highlights a critical gap in supply chain and physical security protocols that IT leaders must recognize extends beyond traditional network-based threats to life-critical infrastructure.
