Networking Tech Vulnerability Could Be Used to Hack Spacecraft: Researchers


The flaw affects Time-Triggered Ethernet (TTE), a networking technology specifically designed for real-time applications and cyber-physical systems with high safety and availability requirements.

TTE is often used to reduce costs and improve efficiency as it allows mission-critical components to exist on the same network hardware as less important systems.

For instance, life support systems can share the network with onboard experiments in the case of spacecraft, robot control systems can share a network with data collection systems in manufacturing facilities, or passenger Wi-Fi could be on the same network as flight control systems in the case of airplanes — this is not the case in current commercial airplanes.
