According to Crypto LaLa, the operations manager of QuantMatter, a Singaporean market maker, disclosed on social media that a hacker took full control of his account and stole more than $11 million of funds from OKX trading accounts, including the main account and sub-accounts. The hacker sold everything for ETH, and all the funds disappeared instantly within 25 minutes. There was no email notification, no two-step verification, and nothing. In addition, Crypto LaLa said that this is the money of the company, and he is a director of the company. OKX is investigating and only hopes that the money can be recovered. According to OKX personnel @Haiteng_okx, the account withdrawal requires email and offline GA authentication, and its offline GA information is managed by the other team. At present, we have not found any leakage of offline GA.
