Hacked Sberbank Memo Puts Russia Chances of Winning War at Seven Percent and Outlines Eight Conflict Scenarios

BLUFContested provenance and an 83% machine-generation score render the leaked memo unreliable as evidence of internal Russian pessimism, regardless of whether its cited figures are accurate.

The hacker group Black Mirror published screenshots of an internal Sberbank memo dated April, dated to before Ukraine's stepped-up refinery strikes, that assigns Russia a 7% chance of achieving decisive military victory 12. The memo, which the hackers say Sberbank chairman German Gref sent to an unnamed correspondent described as among Russia's 50 most influential figures, lays out eight scenarios, with a "Trump deal" freezing the conflict along current lines rated most likely at 32% and a "Korean freeze" without formal agreement at 22% 1. It cites a first-quarter budget deficit of 4.58 trillion rubles, a 45.4% drop in oil and gas revenues, and monthly Russian losses of 20,000 to 25,000 troops 1. Reaching the decisive-victory scenario would require a second mobilization wave of 300,000 to 500,000 troops, and the memo put Russia's economic sustainability at only 12 to 18 months 13. Sberbank has not commented on the leak, and a source in Russia's financial sector told Meduza they had not seen the original document and suspected it was AI-generated, a theory the detection service Pangram supported by finding 83% of the English text machine-generated 3.

Analysis
The memo's authenticity, not its arithmetic, is the fight. A detection tool flags 83% of the English text as machine-generated, and Sberbank's silence leaves both readings open. Reporting traces to a single Insider disclosure, with other outlets relaying rather than independently verifying it. If genuine, the 7% victory estimate and 20,000-25,000 monthly loss figure would be the bleakest internal Russian assessment surfaced yet. If fabricated, Black Mirror or an affiliated actor generated it to seed a war-fatigue narrative ahead of any negotiation push, and no forecast horizon applies until provenance is resolved.
