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

By Patrick Lin, California Polytechnic State University

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.
