SatBleed: Security of Commoditized Communication Modules in Satellites

Substantial reduction in launch and manufacturing costs has resulted in the accelerated deployment of small satellite missions, with commercial off-the-shelf COTS components becoming the prevailing standard for specific subsystems. However, this modular architecture introduces critical security...

Silent Subversion: Sensor Spoofing Attacks Via Supply Chain Implants in Satellite Systems

Spoofing attacks are among the most destructive cyber threats to terrestrial systems, and they become even more dangerous in space, where satellites cannot be easily serviced, and operators depend on accurate telemetry to ensure mission success. When telemetry is compromised, entire spaceborne...

SpyChain: Multi-Vector Supply Chain Attacks on Small Satellite Systems

Small satellites are integral to scientific, commercial, and defense missions, but reliance on commercial off-the-shelf COTS hardware broadens their attack surface. Although supply chain threats are well studied in other cyber-physical domains, their feasibility and stealth in space systems remai...
