Both of those everyday activities, along with many others, are made possible in part because of satellites, those orbiting chunks of metal that only a fraction of the population thinks about on a regular basis. Now, though, security-minded officials in the Pentagon’s Defense Digital Service (DDS), the Air Force and New York-based vendor Red Balloon Security are trying to improve satellite security by sending computer researchers the technology they would need to hack them. It’s part of an effort to ensure that those big satellites orbiting the Earth remain reliable, and keep the GPS navigation running. One research challenge, called Nyan-Sat, is broken up into three parts. Hackers are building their own satellite tracking antennae, exploiting a ground station modem, and then participating in a live-streamed ground station event. […]
