As of today, May 7, 2019, at 17:15:24 (UTC), we have detected a large-scale security breach. Hackers managed to capture numerous user API keys, 2FA codes, and potentially other information. Hackers used a variety of techniques, including phishing, viruses and other attacks. We are still finalizing all possible methods used. There may be other affected accounts that have not yet been identified.

The above transaction is the only transaction affected. This only affected our BTC hot wallet (containing approximately 2% of our total BTC holdings). All our other wallets are safe and undamaged.
The hackers had the patience to wait and carry out well-planned actions at the most appropriate time through multiple seemingly independent accounts. The transaction is structured to pass our existing security controls.
We had the unfortunate situation of being unable to prevent this retreat before it was executed. Once executed, the retraction triggered various alarms in our system. We stopped all withdrawals immediately after that.
Binance will use the #SAFU fund to fully address this incident. No user funds will be affected.
We must conduct a thorough security review. The security review will include all parts of our systems and data, which is a huge asset. We estimate this process will take approximately ONE WEEK. We will post updates frequently as we make progress.
Most importantly, deposits and withdrawals will need to be SUSPENDED during this period. We ask for your understanding in this difficult situation.
We will continue to enable trading so you can adjust your positions if you wish. Please also note that hackers may continue to control certain user accounts and use them to influence prices in the meantime. We will monitor the situation closely. However, we believe that when withdrawals are disabled there is little incentive for hackers to influence the markets.
