Unverified COTS hardware enables persistent attacks in small satellites via SpyChain

08:39 - 14 Oct 2025

SpyChain shows how unverified COTS hardware in small satellites can enable persistent, multi-component supply chain attacks using NASA’s NOS3 simulator. The rise of small satellites has transformed scientific, commercial, and defense operations. Using commercial off-the-shelf (COTS) parts makes them cheaper and faster to build but also introduces new, poorly understood security risks unique to space […]
