Exploiting Spacecraft

Brandon Bailey

Demonstrates command replay, command link intrusion, and GPS jamming attacks against operational spacecraft simulators.

Summary

The Spacecraft Threat Landscape

Space assets increasingly face cyber threats targeting ground stations, satellite communications links, and onboard flight computers controlling mission payloads.

Command Replay and Link Intrusion Attacks

Using high-fidelity spacecraft simulation environments, researchers demonstrated how unauthenticated or weakly protected uplink channels permit command replay attacks and unauthorized command injection.

Denial of Service via GPS Jamming

Simulating localized GPS jamming against spacecraft positioning receivers illustrates how loss of precise timing and orbit determination degrades satellite pointing accuracy and payload functionality.

Defensive Hardening for Space Missions

Mitigating spacecraft exploits requires implementing robust cryptographic authentication on telemetry and telecommand links, securing ground segment control software, and auditing simulated flight hardware.
