Singapore market maker QuantMatter's $11.6 million stored in OKX was stolen, claiming to have offline Google verification

ChainCatcher news, a board member of the Singaporean market maker QuantMatter posted on social media that the company had $11.6 million stored in OKX suddenly stolen by hackers on May 30. The funds were converted into BTC, ETH, USDC, and USDT and transferred to an on-chain address in just 25 minutes, without any email notification or two-factor authentication.

According to reports from Wu, QuantMatter stated that they had set up an offline Google Authenticator, and withdrawals required dual authentication with email and GA, managed by the founder and a partner. It is highly likely that the hackers used the offline GA verification and that the market maker's GA was compromised. The market maker has already reported the incident to the police in Singapore and contacted more than five security agencies for investigation.

Currently, the authenticity of the incident has not been verified, and the reasons for the theft remain uncertain, as the market maker, security agencies, and OKX are all unable to determine the cause, requiring further investigation.
