Ukrainian cyber specialists from the Defense Ministry’s Main Intelligence Directorate (HUR) recently executed a large-scale cyberattack targeting MegaFon, one of Russia’s largest mobile and internet service providers. The attack was reported by HUR sources to have begun early in the morning, affecting residents in Moscow, St. Petersburg, and several central regions of Russia. Users began experiencing significant disruptions in mobile communications, internet access, and poor performance of mobile services and applications. The Russian communications watchdog, Roskomnadzor, later acknowledged a failure in MegaFon’s infrastructure, though it attempted to downplay the extent of the issue.
Russian media eventually revealed that the disruptions were caused by a powerful distributed denial-of-service (DDoS) attack, described as a “carpet-bombing” attack.
Despite MegaFon’s initial claims that its network was operating smoothly, the company admitted that it faced access issues due to external factors, indirectly confirming the attack. The impact of the attack was widespread, affecting not only MegaFon but also other Russian operators, including Yota and NetByNet. As a result, many Russians were temporarily cut off from various online platforms and services, including Steam, Twitch, and Discord.
The attack also had broader implications as some of these platforms are reportedly used by Russian military and intelligence services in their operations against Ukraine. By targeting MegaFon and other operators, Ukrainian intelligence disrupted services that are essential for the Russian military’s communications and online activities. The successful execution of the cyberattack is seen as a significant blow to Russian digital infrastructure, furthering the ongoing cyber conflict between the two nations.
This cyberattack adds to the growing trend of cyber warfare in the ongoing Russia-Ukraine conflict. As the digital frontlines expand, both sides increasingly rely on cyber operations to inflict damage, disrupt operations, and gather intelligence. Ukrainian cyber capabilities have been demonstrated to be highly effective, targeting key Russian infrastructure and hindering Russian efforts in the ongoing war, showing the growing importance of cyber operations in modern warfare.
