Binance estimates that a security vulnerability caused financial losses of approximately $6.3 billion. Binance said preliminary findings indicate that attackers may have used a compromised laptop belonging to a DevOps engineer to make unauthorized withdrawals. The exchange said blockchain partners helped freeze approximately $3 billion in affected assets on-chain. Binance said the SAFU Fund and company funds will cover all losses, and assured users that their funds remain safe. The exchange said deposits and withdrawals were temporarily suspended during security checks.
