Belarusian Cyber Partisans and Silent Crow say they stole 23 terabytes from Russia’s statistics agency, with files allegedly covering wartime losses as public data on the conflict has narrowed.
The Moscow Times reported that messages from the groups appeared on Rosstat’s main site and regional portals. The groups said the files also contained demographic and economic statistics and documents labeled “for official use only.” The Moscow Times said it could not independently verify their claims. Russian authorities have outlawed the organizations and classified them as extremist.
Rosstat told RBC that its monitoring systems identified suspicious activity and gave staff time to respond. The agency denied that databases or information protected by law were exposed. Rosstat placed the incident between Oct. 29 and Nov. 1, saying multiple parts of its online services were targeted. The Moscow Times reported that Rosstat’s main site was inaccessible when it published its story.
Rosstat’s official method for classifying deaths includes a category for deaths tied to military operations. The agency stopped issuing annual cause-of-death statistics in 2024. The Moscow Times reported that other information useful for evaluating the war’s effects is also no longer publicly accessible.
In July 2025, the two groups said they were behind an attack on Aeroflot’s information technology systems that caused widespread disruption, The Moscow Times reported. Russian prosecutors confirmed the attack and opened a criminal investigation into unauthorized computer access.
In January 2025, Silent Crow claimed to have obtained 2 billion property-owner records from Rosreestr, the state real estate registry. Rosreestr denied a leak; The Moscow Times said journalists confirmed some information the hackers had made public.
