What sources claim
- CoinDesk reported that on Ethereum the attacker used a 2025 upgrade built to make ordinary wallets smarter, armed with 50 signatures from Binance's own wallet.
- CoinDesk framed the attack as an Ethereum upgrade that helped drain part of Binance's $6 billion loss.
Still unresolved
- Which specific 2025 Ethereum upgrade was involved, and what would an official Binance or Ethereum Foundation statement or on-chain data show about how it was used?
- What portion of the $6 billion loss the described transaction accounts for, and what would a Binance filing or incident report confirm?
Evidence levels describe source coverage, not the probability that a report is true. Price moves and their timing cannot establish a cause; minute samples show an observed interval and alert thresholds are heuristics. Explanations are model-assisted, with citations and figures checked. Source titles stay in their original language; full articles are not republished.
