The Federal State Statistics Service (Rosstat)’s online resources were subject to a cyberattack, the agency told RBC. Messages from the hacker groups “Cyberpartisans BY” and “Silent Crow,” both of which are considered extremist and banned in Russia, appeared on the main portal and the websites of regional departments. Among other messages, they posted the message “No one will escape responsibility” in Belarusian.
Rosstat’s press service clarified that the attacks were carefully planned and carried out simultaneously on several fronts from October 29 to November 1, “involving a significant number of specialists from various fields and across a wide geographic range of sources.” The agency also asserted that no databases or legally protected information were leaked, as “monitoring systems promptly alerted us to suspicious activity, allowing for a rapid response.” At the time of publication, Rosstat’s website was down.
The hackers themselves reported the theft of 23 TB of data from the service, including information on Russian casualties in the war in Ukraine, demographic and economic statistics, and documents marked “for official use only.”
Rosstat does indeed count deaths as a result of military action: this category is included in its official methodology. However, starting in 2024, the agency stopped publishing final statistics on causes of death. Other data that could have been used to assess the impact of the war also disappeared from public access.
In July 2025, the same hacker groups claimed responsibility for hacking Aeroflot’s information system, which caused a massive outage. The Prosecutor General’s Office confirmed the cyberattack. A criminal case was opened under the article on unauthorized access to computer information.
In January of that year, Silent Crow reported the theft of Rosreestr data, claiming to have obtained a database of two billion property ownership records. The agency denied the leak, but journalists were able to confirm the authenticity of some of the published information.
