tl;dr: Hackers drained roughly $6.3 billion in crypto from Binance hot wallets across at least ten blockchains in a 20-minute attack on October 29, likely initiated via a compromised engineer's laptop. Tracing firms TRM Labs, Chainalysis, and Elliptic attribute the heist to North Korea's TraderTraitor group, citing on-chain overlaps with the prior Bybit and Bitget exploits. About $2.8B (mostly stablecoins) has been frozen, but the remaining $3.3B in Bitcoin, Ether, and XRP cannot be frozen and is being laundered via novel automated patterns.
