DUBAI, United Arab Emirates—The guard in a control room at Iran’s notorious Evin prison springs to attention as one by one, monitors in front of him suddenly blink off and display something very different from the surveillance footage he had been watching.

“Cyberattack,” the monitors flash. Other guards gather around, holding up their mobile phones and filming, or making urgent calls. ”General protest until the freedom of political prisoners” reads another line on the screens.
