Impact: Defacement and access disruptions affecting central and regional websites; delayed releases of key economic statistics
Russia’s Federal State Statistics Service suffered cyber-attacks from 29 October to 1 November 2026, resulting in defacement and access disruptions affecting its central and regional websites. Cyber Partisans and Silent Crow claimed access to approximately 25,000 computers and the theft of 23 TB of data, but the agency denied that its databases had been compromised or protected information leaked and investigated the source of the attacks. Records of combatant deaths identified through analysis of the stolen records were subsequently made public, while system recovery and the provision of key statistics remained disrupted through 15 November.
