Hundreds of multi-ton liabilities—soaring faster than the speed of sound, miles above the surface of the earth—are operating on Windows-95.They’re satellites, responsible for everything from GPS positioning, to taking weather measurements, to carrying cell signals, to providing television and internet. For the countries that own these satellites, they’re invaluable resources. Even though they’re old, it’s more expensive to take satellites down than it is to just leave them up. So they stay up.Unfortunately, these outdated systems makes old satellites prime targets for cyber attacks.A malicious actor could fake their IP address, which gives information about a user’s computer and its location. This person could then get access to the satellite’s computer system, and manipulate where the satellite goes or what it does. Alternatively, an actor could jam the satellite’s radio transmissions with earth, essentially disabling it.
