Cyberattack (Satellite Systems)

Also known as: Cyberattack, Cyber

A cyberattack in satellite communications is an attack directed against the data, software, or information systems associated with a satellite system, including spacecraft onboard processors, ground-segment infrastructure, and user terminals. Cyberattacks target the information carried over RF links and the systems that generate, process, route, store, or interpret that data.

Unlike jamming, which disrupts the RF link itself by overwhelming the receiver on the uplink or downlink, cyberattacks exploit vulnerabilities in digital systems and networks. Their effects may include data corruption or loss, service disruption, denial of access to communications services, and—in severe cases—loss of spacecraft command and control if critical telemetry, tracking, and command (TT&C) systems are compromised. 1,2
