> Changpeng Zhao urged followers to avoid email links and attachments. Binance estimated the security incident’s total impact at about $6.3 billion.

Elon Musk responded with only fire and laughing emojis to an Oct. 28 email-security warning from Binance co-founder Changpeng Zhao on Oct. 30; his post gave no explanation and did not mention Binance’s security incident.

Zhao’s warning urged followers not to open links or download attachments from emails, including messages that appeared to come from trusted contacts.

In its Oct. 30 update, Binance put the estimated impact near $6.3 billion and the amount frozen on-chain at roughly $3 billion. The $6.3 billion figure is an estimated total impact, not a final net-loss figure.

The exchange’s preliminary investigation suggested a compromised DevOps engineer’s laptop may have allowed an attacker to access a service container and submit unauthorized withdrawal transactions. Binance said it found no evidence of a wallet private-key leak.

Binance said it would cover all losses with funds from its Secure Asset Fund for Users (SAFU) and company funds. Deposits and withdrawals were temporarily suspended during security checks.

Binance plans to publish a technical report after its investigation is complete.
