As governments and private companies invest billions in satellites, orbital communications, Earth observation systems, and even plans for space-based data centres, cybersecurity experts are warning that a new attack surface is rapidly emerging. Unlike terrestrial infrastructure, systems operating in orbit cannot be patched easily, inspected physically, or repaired by an on-site IT team. This raises a critical question: how do you protect infrastructure that is hundreds of kilometres from Earth?
A recent experiment by cybersecurity company OPSWAT provides a glimpse into how industry is beginning to address this challenge. The company sent its MetaDefender Kiosk Mini to an altitude of 104,883 feet (31,968 metres) aboard a weather balloon, exposing the device to near-space conditions including freezing temperatures, low atmospheric pressure, high ultraviolet radiation and eventual freefall. Throughout the mission, the system continued scanning and sanitising files while operating entirely offline.
While the test was designed to demonstrate the resilience of the technology, it also highlights a broader issue: space infrastructure is increasingly being viewed as part of the world’s critical infrastructure ecosystem.
Why space is becoming a cybersecurity battleground
Space-based systems are woven deeply into everyday life. Satellites support global positioning systems, weather forecasting, telecommunications, financial transactions, military operations and internet connectivity. As reliance on these assets grows, so too does concern about their vulnerability.
The World Economic Forum’s Global Cybersecurity Outlook 2026 noted that a growing proportion of organisations now consider dependence on space-based assets as part of their cyber risk planning. These concerns are not hypothetical. Cybersecurity researchers and defence analysts have repeatedly warned about threats including satellite jamming, signal spoofing, interception, ransomware attacks on…
