US govt wants DEF CON hackers to pwn this satellite while it's in space. Full details inside
The goal of Moonlighter was to move offensive and defensive cyber-exercises for space systems out of an on-Earth lab setting and into low Earth orbit, according to project leader Aaron Myrick of Aerospace Corp. Not only that, but the satellite needs to be able to handle multiple teams competing to seize control of its software without losing or damaging the whole thing and ruining the project. Thus, an onboard sandbox approach was taken.
To this end, the small satellite runs a software payload that behaves like a real flight computer, which can — hopefully! — to be subjected to multiple, realistic attacks and commandeered without underlying critical subsystems being affected. This year's annual competition will thus be the first time conference hackers get to test their skills against a live, in-orbit satellite. The top three teams will win a monetary price: $50,000 for first place, $30,000 for second, and $20,000 for third.
Because of this, space systems are built in a risk-averse way, and employ redundancy to provide multiple communication pathways to recover a system if it fails, or to debug equipment that's malfunctioning.
