Have you ever watched a movie where a snarky young computer hacker wreaks havoc with civic infrastructure, and wondered if it could happen in real life?
Well, a team of researchers researchers from the University of Michigan had that same question. So they looked into a scenario like this one, featured in the remake of The Italian Job:
"Was that really possible?” said Branden Ghena, who was on the research team. “Could you actually change the light colors? Is that a thing that can really happen, or are these systems as secure as we hoped they were?"
Turns out, the answer is yes – it really can happen.
