Binance Covers $6.34 Billion Hack Losses from Own Reserves Without External Funding

Binance has revealed that it managed to recover user losses from a significant security breach amounting to $6.34 billion entirely from its own balance sheet. The exchange made this announcement on October 31, 2026, assuring users that they would not incur any losses due to the hack.

The recovery funds were sourced from three internal reserves: the Secure Asset Fund for Users (SAFU), a portion of the futures insurance fund, and the company’s own reserves. Binance confirmed that no external borrowing or asset sales were necessary for this recovery.

As of November 1, 2026, Binance reported that approximately 90% of the financial impact from the hack had been replenished, an increase from earlier estimates of around 80%. Notably, ten specific assets, including Bitcoin, Ethereum, and Tether’s USDT, have achieved full reserve backing.

For assets that are not yet fully covered, Binance has committed to purchasing additional tokens on the open market. The exchange has not set a specific deadline for completing this replenishment.

In a bid to enhance transparency, Binance published a new Proof of Reserves snapshot on October 31, 2026, with full zero-knowledge proofs expected to be released on November 3, 2026. This cryptographic method will allow users to verify that their balances are included in Binance’s liabilities without revealing individual account details.

The hack is noted as one of the largest in Binance’s history, and the exchange’s proactive approach to covering user losses contrasts with a broader industry trend where losses are often distributed among users.

New Insights on the Binance Hack

• The Binance breach, which occurred on October 29, 2026, involved the theft of approximately $6.3 billion worth of digital assets.
• Opsek founder Pablo Sabbatella suggests that the attackers may have had access to Binance's systems for weeks prior to the actual theft.
• The attack was executed in a rapid 20-minute window, but the groundwork was laid at least 36 hours before the cash-out.
• The entry point for the attackers was likely a compromised laptop belonging to a DevOps engineer, allowing them to access critical systems.
• Security firms have attributed the attack to a group known as TraderTraitor, which is linked to North Korea.
• Binance has committed to covering approximately 90-95% of the stolen assets using its own reserves, while also freezing $2.7 to $3 billion of the stolen funds in cooperation with stablecoin issuers.
• This incident highlights the need for exchanges to adopt an "assume compromise" mindset, focusing on internal security rather than just external threats.
