According to ChainCatcher, a board member of Singapore market maker QuantMatter posted on a social platform that the company's $11.6 million deposited in OKX was suddenly stolen by hackers on May 30. The funds were converted into BTC ETH USDC USDT and transferred to an on-chain address in just 25 minutes without any email notification or two-step verification.
According to Wu, QuantMatter said that it has set up an offline Google authenticator, and withdrawals require email and GA dual authentication, which is kept by the founder and partner. It is likely that hackers stole the coins using offline GA authentication and the market maker's GA was stolen. The market maker has reported to the police in Singapore and contacted more than 5 security agencies for inspection.
At present, the authenticity of the incident has not been confirmed. The cause of the theft cannot be determined by the market maker itself, security agencies, OKX, etc., and further investigation is needed.
