Hackers Claim 23 TB Theft from Russia’s Rosstat; Agency Denies Protected Data Leak

Belarusian CyberPartisans and Silent Crow claimed they compromised Russia’s Federal State Statistics Service, Rosstat, between October 29 and November 1, 2026, and stole approximately 23 TB of data, including internal electronic document management records. The groups alleged access to central and regional systems, domain controllers, virtualization platforms, and infrastructure management systems. They also reportedly displayed purported Russian military casualty figures from the war in Ukraine on Rosstat’s website; neither the claimed exfiltration nor the casualty figures has been independently substantiated.

Rosstat acknowledged that its information resources were targeted during that period but said it had identified no compromised databases or leakage of legally protected information and that its infrastructure remained operational. Cybersecurity specialists and law enforcement are investigating. The attackers’ claims suggest potentially extensive infrastructure access, but the scope of any compromise and the authenticity of the allegedly stolen material remain unresolved.
