Ukrainian cyber specialists attacked one of Russia's largest internet service providers in Siberia, causing over $834,000 in damages, UkrInform reports. 

The provider itself acknowledged that the cyberattack caused 66 million rubles in damages and confirmed a leak of user personal data.

Provider files complaint with Russian police

Orion Telecom has asked Russian police to open a criminal case over the cyberattack. Under Russian law, the provider could face a fine of up to $189,000 due to the data breach.

Russia Day turned into a day of silence in Siberia

The cyberattack occurred during the summer on Russia Day. On that day, the internet and television went offline in a closed city focused on uranium mining, where Orion Telecom was the only provider. Local social media pages in Krasnoyarsk, Irkutsk, Bratsk, and Abakan were filled with complaints about the lack of connectivity.
