Cyberattack on Rosstat Servers
The Russian Federal State Statistics Service (Rosstat) admitted that its servers were hit by coordinated cyberattacks between October 29 and 31. However, it denied claims that tens of terabytes of data had been leaked, as asserted by hack groups like the Belarusian CyberPartisans and Silent Crow. Rosstat stopped publishing annual cause-of-death statistics in 2024, but the hackers say that the huge new 23TB data haul includes data on Russian wartime losses marked “for official use only.” A new chart shared by the hack groups using the data suggests that as many as 50,000 Russian soldiers are killed every month.
Rosstat is comparable to national statistical bodies such as the U.S. Census Bureau or the Office for National Statistics in the UK. While it is not a traditional military infrastructure target, the potential exfiltration of accurate war casualty figures from the dataset would represent a significant intelligence development.
Today @cpartisans and SilentCrow took down Russia's Federal State Statistics Service — the nerve center behind every socioeconomic number this regime produces. Full breakdown below 👇 https://t.co/wUKfyUi6y6November 1, 2026
Scale of Infrastructure Impact
Both the Belarusian CyberPartisans and Silent Crow claim to have acquired extensive sensitive data from the Russian government during the breach. The former group published evidence and a breakdown stating that the entire IT infrastructure was compromised, including domain controllers, databases, servers, virtualization, document workflow, workstations, admin consoles, and VPNs. Systems reportedly disrupted include STATEK, CSOD, Demography, SED, ESSO, OFSN, internal employee surveillance, and StatRegister.
The situation remains a developing story, with the hackers promising to share further sensitive information from Rosstat after analyzing the contents. The Rosstat website was defaced with hacker messages and logos and remained inaccessible following the incident.
Casualty Claims and Data Analysis
A graphic shared by the Belarusian CyberPartisans alongside the Silent Crow logo indicates that between 25,000 and 50,000 Russian soldiers were killed monthly over the preceding two years, with the October 2026 figure approaching 50,000, assuming the authenticity of the leaked data.
The same hacking collectives previously claimed responsibility for high-profile cyberattacks in 2025, including a disruptive incident affecting Aeroflot IT systems and a breach of a state real estate company compromising two billion records.
