Binance vows to cover $6.3bn hack losses as withdrawals stay frozen

Key Points

1. Binance says it will absorb all customer losses from a breach estimated at $6.3 billion.
2. Deposits and withdrawals remain suspended, with about $3 billion in affected assets frozen on-chain.
3. The theft ranks among crypto's largest and knocked Bitcoin, Ether and BNB sharply lower.

The latest:

Binance has pledged to cover every customer loss from a security breach it estimates at $6.3 billion, drawing on its insurance fund and company reserves. A spokesperson for the exchange said user funds are safe and that an updated Proof of Reserves will be published once remediation is complete. Deposits and withdrawals remain suspended while security teams investigate.

Details:

• The pledge: A Binance spokesperson said the exchange will cover all losses from the SAFU fund and company funds, and that users will not bear the financial impact. The spokesperson added that an updated Proof of Reserves will follow once remediation work is finished.
• The fund: SAFU, the Secure Asset Fund for Users, was set up in 2018 to shield customers from losses caused by security breaches and has historically held roughly $1 billion. Binance has not disclosed how much it expects to draw from the fund versus its own reserves.
• Frozen assets: The exchange said about $3 billion in affected assets had been frozen on-chain. Deposits and withdrawals were temporarily suspended while security teams examined the incident, and Binance did not set out a timetable for restoring either service.
• How it happened: An initial investigation suggests the breach may have originated from a compromised laptop belonging to a DevOps engineer, according to Binance. That access allowed attackers to reach a service container and submit unauthorised withdrawal transactions.
• Wallet keys: Binance said it had found no evidence that wallet private keys had been leaked, and that it had revoked the authorisation for the affected address. The exchange gave no indication that the custody system was compromised beyond that single address.
• Market reaction: Bitcoin fell 4.5 per cent to $76,664 early on Friday. Ether dropped 5.2 per cent and BNB, the token tied to Binance itself, slid 7.1 per cent — the steepest fall of the three, and a sign the damage was read as company-specific.
• Leverage wipeout: More than $1.5 billion in leveraged cryptocurrency positions were liquidated over a 24-hour window as prices slid, compounding the selling pressure triggered by news of the breach.
• The tracing effort: Binance said it is working with law enforcement and blockchain intelligence partners to trace the stolen assets. It has not named the agencies or firms involved, nor said how much of the missing $6.3 billion it expects to recover.
• User response: The incident prompted concern and scepticism among cryptocurrency users on social media, where doubts focused on the gap between the scale of the loss and the exchange’s publicly known insurance cushion.

Background:

Binance is the world’s largest cryptocurrency exchange by trading volume. SAFU was created in 2018 after a series of exchange hacks across the industry, funded by setting aside a share of trading fees to reimburse users when platforms are breached.

Between the lines:

The arithmetic is driving user scepticism: a fund historically sized at about $1 billion against losses estimated at $6.3 billion means most of the shortfall must come from company reserves, which Binance has not quantified. The promised Proof of Reserves update is the test of the pledge, and BNB’s 7.1 per cent drop shows traders pricing that uncertainty.

What’s next

Watch for the updated Proof of Reserves Binance promised, the resumption of deposits and withdrawals, and any disclosure of how much of the $3 billion in frozen assets is recovered or how remaining losses are funded.
