Binance users withdrew $3.6 billion in assets after the exchange reopened on Sunday following what major organizations, including the FBI, say was the largest cryptocurrency hack in history. The breach affected $6.3 billion in digital assets and forced Binance to suspend all transactions.
The FBI has accused North Korea of responsibility for the attack. Binance said it has covered around 95% of stolen assets, with the remaining amount to follow. The firm committed to covering all losses.
Withdrawals between 06:00 and 15:30 GMT on November 1 totaled $4.649 billion, offset by $1.01 billion in deposits. The net outflow represented just over 2% of Binance's $171 billion in assets under management. An initial spike in withdrawals later declined and began stabilizing, Binance said.
Binance has reserved more than $6.3 billion to address fallout from the attack. Withdrawals of major cryptocurrencies including Bitcoin and Ethereum have resumed, with additional services returning in phases once security checks complete.
Alec Zebrick, senior manager in global services at Chainalysis, told the BBC that stolen funds continue to be laundered actively across thousands of addresses and deposits.
Binance said early checks suggest the incident may have begun with a compromised laptop belonging to an engineer. The FBI published a list of cryptocurrency wallet addresses linked to the attack and urged industry partners to block related transactions. Binance.com's US-facing platform was not affected.
