Ukrainian Cyberattack Targets Major Siberian Internet Provider
On October 15, 2025, cyber specialists from the Main Intelligence Directorate of the Ukrainian Ministry of Defense launched an attack on the infrastructure of “Orion Telecom,” one of the largest internet providers in Siberia. The company reported losses amounting to 66 million rubles, reports 24brussels.
According to Ukrainian intelligence sources, the incident was revealed through a statement submitted by “Orion Telecom” to Russian police. The provider acknowledged a data breach that compromised user personal information and has requested law enforcement to initiate a criminal investigation.
Furthermore, under Russian law, “Orion Telecom” may also face a fine related to the data leak, which could reach up to 15 million rubles.
In June, Ukrainian cyber specialists had already targeted “Orion Telecom.” Reports from Ukrainian intelligence indicate that this provider services several strategic facilities and is widely used by Russian security agencies in their ongoing conflict against Ukraine. Following the previous cyber assault, internet disruptions occurred across multiple Russian cities, impacting even a closed city engaged in uranium mining, as “Orion” was its sole internet provider.
Subsequently, Ukrainian hackers executed another significant operation against the network infrastructure of PJSC “Gazprom,” resulting in substantial financial damage. This attack led to the destruction of a large volume of databases and the implementation of specialized software designed to irreversibly delete data from the Russian monopolist’s information systems.
