Binance says attackers drained about $6.3B from hot wallets, mostly in around 20 minutes across 10 chains, in what TRM Labs and Chainalysis attribute to North Korea's TraderTraitor group linked to Lazarus. That attribution is why posts like Kalshi_Crypto, WSJ and spectatorindex call it North Korea's $6.3B hack and the largest heist in history, topping the $1.5B Bybit hack.

Binance says the entry was a compromised DevOps laptop reaching a service container to submit unauthorized withdrawals, with no private key leak, later adding more breach points and calling it a complex attack. Co-CEO Richard Teng said attackers used Ethereum EIP-7702 delegation to keep withdrawing, and Binance puts frozen funds at about $3B via issuers and partners.

Binance says it reserved over $6.34B and will cover all losses via SAFU plus company funds, buying back impacted tokens via market and OTC. Withdrawals stay paused while it rebuilds the withdrawal service, expected back in about 40-45 hours, deposits work normally, with a full Proof of Reserves promised by Monday.

Bitcoin fell with the news to about $76,410 on Binance spot, down about 5.5% in 24h at 18:53 UTC Oct 30, near $76.3k-76.4k across venues. The 60% chance Bitcoin drops to $70,000 before $100,000 in the Kalshi post is that account's claimed prediction market odds, not a verified trade.
