Russian hackers organize power outages in regions of Ukraine - they break into control rooms of power stations and turn off the power remotely. Cyber experts gained access to the server that connected the internal network of the energy infrastructure to the Internet. With it they were able to remotely control substations and turn off the electricity. The hackers also gained access to the control room cameras. In the recording, workers take shelter after an air raid warning was announced, and messages with greetings from Russia appear on the screens. In the Vinnytsia region, after such an attack, emergency shutdowns were introduced: part of the region spent more than five hours without electricity.
