SatBleed: Security of Commoditized Communication Modules in Satellites
An in-depth security evaluation of COTS communication modules in small satellites.
The rapid deployment of small satellite missions has led to increased use of commercial off-the-shelf (COTS) components. However, this modular architecture introduces significant security risks, particularly in the Communication Subsystem (COM). This study constructs a tailored threat taxonomy for attacks on the COM subsystem and analyzes representative systems from various vendors, uncovering severe vulnerabilities in firmware, protocols, and architectural designs.
