According to the source, multiple Russian users are complaining about malfunctions in online operations of the mobile communication service provider Rostelecom, the lack of Internet access from the mobile phone operators MTC and Beeline, about the lack of connection to Yandex.pochta email platform, as well as Yandex.yeda online meal delivery service and Yandex.taxi online booking service. All the Russian online resources attacked are providing support and finance for the war Russia is waging in Ukraine, the source said.

In addition to this massive cyber attack, online resources of dozens of major industries in the Russian Federation, who are providing support for Russia’s arms manufacturing industry, have been affected.

Brook INEUM (supplier of equipment and software products, servers, processors, etc.).

Sources claim that the cloud and file storage of the Internet service providers Mail.ru, VDSin, and Quidex, LLC National Cable Networks, PJSC Central Telegraph and others were among the targets for the attack.  Moreover, at least two dozen resources of companies manufacturing lighting equipment, diesel stations, anti-ballistic protection devices, as well a number of hosting service providers and others came under attack.

As a result of the cyber attack, at least 33 servers and 283 service PCs of industrial facilities were affected, 15 cloud and file storages destroyed, and 21 websites disabled in the aftermath of the attack. A total of around 70 terabytes of information was destroyed.  On top of that, Ukrainian hackers left "plugs" with propaganda content in support of Ukraine's victorious actions on the websites of the platforms they destroyed.
