Growing Cyber Threats Targeting Space Sector in 2025

• •407 cyber incidents reported against 183 space entities in 2025.
• •DDoS attacks were the most common, with hacktivists as primary threat actors.
• •No documented attacks on satellites, indicating potential detection gaps.

In 2025, 407 cyber incidents were reported against 183 space-related entities, primarily affecting ground systems and organizational networks. The incidents included DDoS attacks, ransomware, and data theft, with hacktivist groups being the most active threat actors. Notably, no attacks were documented against satellites in orbit, but this does not imply their security, as most lack onboard cyber detection sensors. The incidents closely followed geopolitical tensions, including conflicts in Ukraine, Iran, and Gaza. The assessment highlights significant gaps in cyber threat intelligence and the need for improved detection and reporting mechanisms in the space sector.
