Quick Summary

Belarusian and Ukrainian hackers have uncovered over 400,000 Russian death certificates linked to the war in Ukraine since Putin's invasion nearly five years ago. The leak reveals that Russia has suffered nine times more fatalities than all Soviet and Russian wars combined since World War II. Hacker groups Cyber Partisans and Silent Crow accessed Rosstat’s records following a November breach, while Rosstat denied sensitive data loss despite confirming the hack. This number aligns with earlier estimates by war analysts and British intelligence.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
