The "New Space" era has transformed space into a critical domain for security, commerce, and digital infrastructure, but it has also introduced significant cybersecurity challenges. The digitalization of satellite systems has expanded the attack surface for cyber threats, making Anti-Satellite (ASAT) cyber operations a growing concern. This paper examines the intersection of cyberspace and space security, highlighting satellite vulnerabilities, supply chain risks, and global stability implications. It also explores the European Union’s strategic response, including the EUSSD, strengthened legislation, and inter-agency cooperation. Addressing cyber-ASAT threats will require international collaboration, strong cybersecurity policies, and proactive mitigation strategies to ensure space resilience.
