Leaked Russian records link 412,576 death certificates to the Ukraine war, the Guardian reports — a toll Moscow has not published
Leaked data from Russia's state statistics agency Rosstat contains 412,576 death certificates explicitly linked to the war in Ukraine, the Guardian reports — more than 400,000 Russian deaths since the full-scale invasion began nearly five years ago. The Guardian says it could not independently verify the whole dataset, which was obtained by two hacking groups; Rosstat confirmed it had been hacked but denied that sensitive information had leaked. Other estimates point the same way: British intelligence put Russian military deaths at about 500,000 in September, and the independent outlet Mediazona has named nearly 286,000 dead and estimates the true toll is closer to half a million.

Key points
- Leaked Rosstat records link 412,576 death certificates to the war — the hacking groups' count, reported by the Guardian, not a verified toll.
- The Guardian could not independently verify the whole dataset; Rosstat confirmed a hack but denied sensitive data leaked.
- British intelligence estimated about 500,000 Russian soldiers killed; Mediazona has named nearly 286,000 and estimates closer to half a million.
- An expert who studied the data says it looks authentic and probably understates the toll.
What happened
Russia has treated its war dead as a state secret since the early months of the 2022 invasion, publishing no official toll while independent counters — Mediazona naming the dead one by one, Western intelligence estimating — built the picture from outside. A leak from inside the state's own statistics agency is a different kind of evidence: the state's own paperwork, if authentic.
The leak lands in the week US-brokered talks between Russia, Ukraine and the United States open in Abu Dhabi. The Guardian reports that a person familiar with President Putin's thinking said the scale of the losses was more likely to harden his resolve than to push Moscow toward a settlement.
Claim by claim
Why this label: The dataset was obtained by the Belarusian opposition-linked hacker group Cyber Partisans and the Ukrainian collective Silent Crow, and shared with the Guardian and a small group of other outlets. The Guardian says it could not independently verify the authenticity of the entire dataset, so the 412,576 figure is carried as the groups' count of the leaked records, not as a confirmed toll.
On the ladder: the evidence so far sits low — early, single or social sources. We publish the claim as a claim, never as fact.
Why this label: Rosstat's position, as reported by the Guardian. Russia has not published a death toll since the early months of the invasion, and military casualty information is treated as a state secret.
On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.
Why this label: Both estimates as reported by the Guardian. Mediazona's named count is a floor built name by name; its estimate, and British intelligence's, are estimates, not counts of records.

Why this label: Kluge's assessment, as reported by the Guardian. It is an expert judgement on the data, carried as such; it does not by itself verify the dataset.

Why this label: The patterns are drawn from the leaked dataset as analysed and reported by the Guardian; they stand or fall with the dataset itself, which has not been fully verified.

What we know / what we don't know yet
What we know
- That Rosstat confirmed a hack and denied sensitive data leaked, and that the Guardian could not verify the entire dataset.
- The outside estimates the leak is measured against: British intelligence at about 500,000 killed, and Mediazona's nearly 286,000 named dead.
What we don't know yet
- Whether the leaked dataset is authentic in full — no independent verification of the whole of it has been published.
- Russia's true death toll: the leaked count, the named count and the intelligence estimates differ, and Moscow publishes none.
Why it matters
Every previous number for Russia's dead was an estimate or a name-by-name count from outside the state. These records, if they hold up, are the state's own count — 412,576 certificates — and even the analyst who vouches for them says the real toll is likely higher. What Moscow does with a number it has never admitted is now the open question.
