Binance estimated that a security breach caused about $6.3 billion in total financial damage. Binance said preliminary findings suggest an attacker may have used a DevOps engineer's compromised laptop to enable unauthorized withdrawals. Binance said blockchain partners helped freeze approximately $3 billion of affected assets on-chain. Binance said the SAFU fund and company funds will cover all losses and assured users that user funds remain safe. Binance temporarily halted deposits and withdrawals during security checks, the exchange said.
