Hacking traffic control systems was a topic presented at Def Con 22 by IOActive Lab’s Cesar Cerrudo. But now security researchers have hacked traffic lights in real life and say it’s easy to do a person only needs a laptop and wireless card operating on the same 5.8 gigahertz frequency as the wirelessly networked traffic lights, then he or she could access the entire unencrypted network. If you are gamer, then you might have “hacked” traffic lights in the video game Watch Dogs to cause epic wrecks and allow you to escape the cops.
You’ve seen traffic lights hacked in movies like Live Free or Die Hard or The Italian Job.
