Binance’s initial review found that the total financial impact of the security breach could be approximately $6.3 billion. The company said user funds were safe.
Work with industry partners led to approximately $3 billion in assets being frozen on the blockchain. Binance said it would cover all resulting losses through the SAFU fund, established to protect users, and its own resources.
The breach may have begun when the computer of an engineer responsible for the company’s software and systems infrastructure was compromised. The attackers used this access to reach Binance’s service infrastructure and carry out unauthorized withdrawals.
In a company statement, Binance said there was no evidence that the private keys for cryptocurrency wallets had been leaked.

Transactions temporarily suspended
Binance temporarily suspended deposits and withdrawals during its security checks. The affected address had its access revoked, while the company worked with law enforcement to recover the assets.
Binance announced that it would publish a comprehensive report containing the technical details of the incident, along with updated reserve information, after the review was completed.
