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 ground stations and cyber-enabled disruption of communications networks.
Recent geopolitical tensions have further elevated concerns around the resilience of satellite infrastructure. Several governments have identified space as a strategic domain alongside land, sea, air and cyberspace, creating renewed interest in securing orbital assets against both criminal and nation-state adversaries.
According to OPSWAT founder and CEO Benny Czarny, traditional cybersecurity assumptions may not apply in space. “Cybersecurity in space cannot be built around the idea that someone on Earth will always be available to fix the problem,” Czarny argues.
This thinking reflects a broader shift towards what cybersecurity professionals call zero-trust architecture and prevention-first security. Rather than assuming systems can be patched after a compromise, security controls must prevent malicious activity from occurring in the first place.
OPSWAT’s MetaDefender Kiosk employs a technology known as Content Disarm and Reconstruction (CDR). The approach assumes that any incoming file could be malicious. Instead of attempting to identify malware signatures alone, the system strips potentially dangerous active content from files and reconstructs clean versions before they enter protected environments.
For highly isolated environments, whether nuclear facilities, military installations, offshore platforms or potentially spacecraft, such preventative approaches are gaining attention.
One emerging trend attracting considerable interest is the prospect of orbital data centres. Several commercial ventures have proposed locating computing infrastructure in space, citing advantages such as access to solar power, reduced terrestrial cooling requirements and proximity to satellite networks. While many of these concepts remain experimental, they illustrate how rapidly the space economy is evolving.
The implications for cybersecurity are significant. Traditional security teams often rely on continuous monitoring and cloud-based threat intelligence. These options may not be available when systems are operating hundreds of kilometres above Earth. As a result, future orbital infrastructure may require highly autonomous cybersecurity systems capable of making decisions without immediate human intervention.
While malware remains a concern, the threats facing space infrastructure extend much further. Potential attack scenarios include GPS spoofing, satellite command hijacking, and communication signal interception. In addition, electronic warfare activities, data exfiltration, and supply chain compromise add further concerns.
The rise of generative AI has added another dimension to the challenge. Security researchers increasingly warn that AI tools can be used to develop more convincing phishing campaigns, automate vulnerability discovery and accelerate cyber offensive operations. This has strengthened arguments for security architectures that minimise exposure rather than relying solely on detection.
Canada’s growing role in space cybersecurity
Canada has a particular stake in these developments. The country has a long history in space technology through the Canadian Space Agency and is internationally recognised for innovations such as the Canadarm robotic systems used on the Space Shuttle and International Space Station.
Today, Canada’s space sector supports satellite communications, Earth observation and scientific research. Companies including Telesat are investing in next-generation low-Earth orbit satellite networks designed to provide broadband connectivity across Canada and globally. These developments have increased attention on satellite resilience and cyber protection. Canadian government agencies have also highlighted critical infrastructure security as a national priority, particularly as cyber threats continue to evolve.
The growing intersection of artificial intelligence, cybersecurity and space operations is attracting interest from both Canadian researchers and defence planners. As satellite constellations expand, securing them against sophisticated cyberattacks will become increasingly important.
