SatBleed: Security of Commoditized Communication Modules in Satellites
Researchers find severe flaws in COTS satellite communication modules, linking at least 28 in-orbit missions to takeover risk.
A security study of commercial off-the-shelf satellite communication modules finds severe weaknesses in firmware, protocols, and architecture. The authors build a threat taxonomy for the always-exposed COM subsystem and compare modules from multiple vendors. Correlating findings with open-source telemetry, they infer at least 28 missions already in orbit could be taken over. They argue commoditized satellite radios are a neglected attack surface affecting dozens of missions.
- COTS communication modules are the trusted, always-exposed command path on small satellites.
- Vulnerabilities span firmware, protocols, and architectural design across vendors.
- Open telemetry correlates findings to at least 28 in-orbit missions.
- Authors warn of hostile takeover risk and call for urgent hardening.
