Binance, the world's largest cryptocurrency exchange, has replaced $6 billion of the $6.3 billion stolen in a hack using company funds, Reuters reported on Oct. 31.

Binance bought tokens with company money to make up the losses, the report said. Binance said on X, "We have already replaced $6 billion of the losses." The company said the remaining less than 10 percent consists of low-liquidity assets, so it may take longer to secure what is needed.

The funds for the token buybacks came from part of the $1 billion Secure Asset Fund for Users (SAFU), part of a futures insurance fund and Binance's own funds, Reuters reported.

The U.S. Federal Bureau of Investigation (FBI) identified the North Korean government-backed hacking group TraderTraitor as behind the attack. The FBI said it detected members of the group converting the stolen assets into ethereum and expected additional money laundering. Analysts had earlier pointed to North Korea as being behind the attack and said it could be the largest financial theft on record. North Korea has for years denied financial theft using state-linked cyber organisations.

Binance is freezing some of the stolen assets with industry partners.

Binance has recalculated its asset holdings as of 0000 GMT on Oct. 31 in line with its proof-of-reserves process. Holders of 10 tokens, including bitcoin and ethereum, will be able to check whether their assets are held at a minimum 1:1 once the full proof is released.
