Last year, the FBI opened a Cyber Range in Huntsville, Alabama, for simulating cyberattacks. Think of it sort of like the famous Hogan’s Alley, but for modern digital crime training. It’s a massive 22,000 square-foot replica of an entire town, complete with a convenience store, gas station, hospital, and even fully furnished houses.

It’s a training facility where the bureau can recreate real-world scenarios for training and research purposes. All of the various buildings and facilities are hooked up the way they would be in a real town. There’s even a small data center with over 200 servers that can be hacked, infected with malware, and studied. But, importantly, all of the systems in the fake town are cut off from the outside world, which means there’s no danger of any malicious code or anything from escaping containment.

Students practice performing forensic investigations on car entertainment systems, hospital computer networks, and corporate security systems. They can see how various cyberattacks might affect power grids or spread through home networks.

While the facility opened last year, the FBI only shared a video this week, giving the public its first glimpse inside.
