On an episode of Mr. Robot, the good guy hacks into a data-storage plant’s HVAC system and raises the temperature enough to start a fire. He does it by attaching a credit-card-size computer called a Raspberry Pi, which is a real thing that exists outside of TV, to the facility’s thermostat system. This may seem like something a bad guy would do, but the world of cybersecurity—and, frankly, the show—can be confusing.
And if you think it sounds far-fetched, you should see what researchers are working on at the Hume Center for National Security and Technology, on Virginia Tech’s Ballston campus.
