Right now there are thousands of satellites orbiting above our heads performing crucial tasks. At the end of the day, they’re just computers running software – albeit at thousands of miles up and thousands of miles per hour. Can they be hacked? What are the dangers? Aaron Myrick and the Hack-A-Sat team are trying to answer those questions. And they’re doing it by launching an actual satellite into low earth orbit for this year’s DEF CON hacking contest and asking talented hackers from around the world to take their best shot.
