A theft of roughly $6.3 billion in cryptocurrency from Binance unfolded largely within 20 minutes on October 29, across wallets on at least ten blockchains, including Bitcoin, Ethereum, Tron, and Solana. Investigators say preparation began at least 36 hours earlier: the attackers tested code and transactions on several wallets, rehearsed the operation, then installed the final code on Binance hot wallets - internet-connected wallets used to process customer withdrawals. Binance halted deposits and withdrawals and says it will cover losses while working with law enforcement. Its initial suspicion of a compromised employee laptop has broadened into an investigation of several possible points of entry.
Crypto-tracing firms TRM Labs and Chainalysis see signs pointing to TraderTraitor, a sophisticated North Korean hacking group, though Binance and law enforcement have not confirmed that attribution. Analysts cite similarities to past attacks, including a suspected compromised staff device, advance rehearsals, and stolen funds mixing with money from a previous exploit linked to North Korean hackers. Companies initially froze about $3 billion; Elliptic estimates roughly $2.8 billion, mostly stablecoins, has been immobilized. Much of the remaining $3.3 billion is Bitcoin, Ether, and XRP, which cannot be frozen directly and may be intercepted only if it reaches an exchange or other service. Investigators report rapid, automated transactions and unfamiliar laundering patterns, suggesting substantial sums could remain beyond recovery.
