To guard against cyberattacks in space, researchers ask ‘what if?’

Protecting Space Systems from Cyber Attack | by The Aerospace ...

If space systems such as GPS were hacked and knocked offline, much of the world would instantly be returned to the communications and navigation technologies of the 1950s. Yet space cybersecurity is largely invisible to the public at a time of heightened geopolitical tensions.

Cyberattacks on satellites have occurred since the 1980s, but the global wake-up alarm went off only a couple of years ago. An hour before Russia’s invasion of Ukraine on Feb. 24, 2022, its government operatives hacked Viasat’s satellite-internet services to cut off communications and create confusion in Ukraine.

I study ethics and emerging technologies and serve as an adviser to the U.S. National Space Council. My colleagues and I at California Polytechnic State University’s Ethics + Emerging Sciences Group released a U.S. National Science Foundation-funded report on June 17, 2024, to explain the problem of cyberattacks in space and help anticipate novel and surprising scenarios.

Space and you

Most people are unaware of the crucial role that space systems play in their daily lives, never mind military conflicts. For instance, GPS uses signals from satellites. GPS-enabled precision timing is essential in financial services where every detail – such as time of payment or withdrawal – needs to be faithfully captured and coordinated. Even making a mobile phone call relies on precise coordination of time in the network.

Besides navigation for airplanes, boats, cars and people, GPS is also important for coordinating fleets of trucks that transport goods to stock local stores every day.

Earth-observation satellites are “eyes in the skies” with a unique vantage point to help forecast the weather, monitor environmental changes, track and respond to natural disasters, boost agricultural crop yields, manage land and water use, monitor troop movements and much more. The loss of these and other space services could be fatal to people vulnerable to natural disasters and crop failure. They could also put global economics and security at serious risk.

Many satellites are crucial for tracking natural and human activity here on Earth.

Factors in play

In our report, we identified several factors that contribute to the increasing threat of space cyberattacks. For instance, it’s important to recognize that the world is at the start of a new space race.

By all accounts, space is becoming more congested and more contested. Both nation-states and private companies, which are underregulated and now own most of the satellites in orbit, are gearing up to compete for resources and research sites.

Because space is so remote and hard to access, if someone wanted to attack a space system, they would likely need to do it through a cyberattack. Space systems are particularly attractive targets because their hardware cannot be easily upgraded once launched, and this insecurity worsens over time. As complex systems, they can…
