Binance's initial investigation into the security incident suggests it may have involved a compromised DevOps engineer’s laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions. The estimated total impact is around $6.3 billion. Binance has frozen approximately $3 billion of affected assets on-chain and confirmed it will cover all losses from its SAFU fund and company funds, ensuring user funds are safe. The exchange has temporarily suspended deposits and withdrawals, revoked affected address authorization, and engaged law enforcement and blockchain intelligence partners to trace and recover funds. No evidence of any wallet private key leak has been found.
