Hacktivists claim 23TB breach of Russia's Rosstat, including war-death data

Belarusian group Cyber Partisans and Silent Crow say they stole statistics on Russian military losses; Rosstat confirms an attack but denies any leak.

What to know

  • Cyber Partisans and Silent Crow claim to have stolen 23TB of data from Rosstat, including statistics on Russian military losses in Ukraine.
  • Rosstat confirms a coordinated attack occurred between Oct. 29 and Nov. 1 but denies any database or legally protected information was leaked.
  • Leaked data is reported to suggest as many as 50,000 Russian military deaths per month, a claim that cannot be independently verified since Rosstat stopped publishing cause-of-death statistics in 2024.

    Silent Crow details scope of the Rosstat intrusion

    Silent Crow issued a statement saying the hackers gained access to Rosstat's central office, regional branches and its Main Interregional Center for Processing and Dissemination of Statistical Information, describing it as an intrusion into a federal agency's full infrastructure rather than isolated servers.

    “The bulk of the data consists of databases, internal documents, official information and data from employees' work computers. The scale of the incident goes far beyond the compromise of individual servers or user accounts.”
