Binance’s $6.3B Hack Exposes a New Hot-Wallet Security Risk

Binance’s preliminary findings point to compromised operational infrastructure rather than a confirmed leak of wallet private keys. Blockaid identified a successful EIP-7702 delegation among 50 authorizations submitted against a live hot wallet. Aave’s emergency restrictions demonstrate how stolen exchange assets can create risks for decentralized lending markets. A compromised employee laptop may have been enough to expose billions of dollars in cryptocurrency without the attacker directly stealing Binance’s hot-wallet private keys. That is the central security question emerging from the October 29 incident , which Binance now estimates had an impact of approximately $6.3 billion.
