MegaFon

MegaFon is a Russian telecommunications operator that provides mobile and internet services to customers within the country. Its operations are reported to include service delivery in major urban centres such as Moscow and St. Petersburg as well as in central regions of Russia. The company functions under the oversight of Russia's communications regulator, which monitors its network performance and incident responses. As a provider of essential connectivity, MegaFon supports both consumer and business communications across its service area. The operator’s role in the Russian telecom sector positions it as a key component of national communications infrastructure.

On 24 January 2025, MegaFon experienced a significant cyberattack carried out by Ukraine’s Defense Intelligence Main Directorate (HUR), which resulted in widespread disruptions to its mobile and internet services for users in Moscow, St. Petersburg and central regions. The attack also affected other providers such as Yota and NetByNet and temporarily limited Russian access to third‑party platforms including Steam, Twitch and Discord. Russia’s communications regulator acknowledged the outage and attributed it to a successful distributed denial‑of‑service (DDoS) attack targeting MegaFon. While the regulator cited the DDoS as the cause, MegaFon itself stated that its network operations were normal but noted unspecified external factors affecting connectivity. This incident underscores the operator’s importance as a critical service provider and highlights its exposure to sophisticated cyber threats. No explicit details regarding MegaFon’s size, ownership structure or subsidiary relationships are available in the supplied information.
