This Coin-Sized Device Can Hack a Boeing 737

Researchers describe a practical avionics vulnerability in which a tiny hardware implant hidden in an obscure connector can connect to a plane's Wi‑Fi and relay spoofed commands to onboard systems, potentially confusing pilots or causing unsafe behavior; the paper outlines mitigations (remove or epoxy connectors, software defenses, electrical isolation, cryptographic authentication) and experts warn the threat model for sensitive systems must be updated given the feasibility of the attack.
