2025: Hacker attack. The main trunk router is damaged

The Russian Datahouse data center network was subjected to a coordinated cyber attack, which disrupted the configuration of the main backbone router of the data network. The attack also affected telecom operator Citytelecom, both companies are part of the perimeter of the Filanko group of companies. The incident occurred on the night of August 11, 2025 at about 01:00 Moscow time.

Citytelecom duty services automatically recorded a network infrastructure malfunction and immediately started diagnosing the system. Engineering teams acted in stages, consistently checking each segment of the network to establish the causes of the malfunction. During the restoration of control, experts confirmed the safety of key data and critical server systems.

Initial technical analysis of the nature of the attack excluded the use of distributed denial of service technologies. Attackers used other methods of influencing network equipment, which required specific approaches to system recovery. The attack was aimed specifically at the core of the network infrastructure of companies, which indicates the targeted nature of cyber activity.

Thanks to the well-coordinated work of specialized technical divisions and increased attention to information security systems, most of the affected services were restored by the evening of August 11, 2025. The company regularly improves the protection of IT infrastructure, which made it possible to minimize the consequences of the incident and quickly localize problem areas of the network.

Aleksei Soldatov, General Director of the Filanko Group of Companies, noted that IT engineering departments are constantly preparing for possible attacks, improving defense systems. Careful pre-preparation, availability of backups and a segmented security system allowed the team to quickly localize the problem and restore most of the infrastructure, he said.^[1]

The history of the development of the DataHouse data center network began in 2006 with a small data center in Moscow. As of August 2024, the company operates facilities not only in the Russian capital, but also in Yekaterinburg and St. Petersburg. It is said that there are joints with more than 540 Internet providers through their own Cloud-IX traffic exchange point (Msk-IX, Spb-IX, Ekt-IX, D-TEL, DEC-IX). DataHouse provides services for renting servers and server racks, accommodation of equipment, etc.

The previously launched Moscow data center DataHouse, called Copper Foil, is located near the Nagornaya metro station. The data center combines eight rooms, and the total number of server racks and cabinets exceeds 500. In the data center, two types of cooling of the cold corridor and energy switchboards were designed: precision and chiller. The facility is connected to the power supply according to the 1st category from several independent city substations, which come by N-feeders from two CRPs according to the voltage level of transformers 10/0.4 kV. The data center is connected to the central core of the MMTS-9 network through two independent FOCL routes laid in the telephone sewer by separate highways. The total redundant backbone capacity of the data center is 100 Gbps with the possibility of operational increase.^[2]
