According to CoinMeta, Wu said that on November 10th at 11:07 (Beijing time), a hacker exploited a loophole in the platform's internal accounting system for fund transfers between sub-accounts to artificially increase account balances and initiate withdrawals. As a result, the hacker successfully withdrew 2,234,391 USDG tokens from the platform. Additionally, about $3 million in withdrawal requests were intercepted by the platform's cross-chain bridge limit mechanism and subsequently cancelled. arcus temporarily suspended all withdrawals at 12:07 on the same day, repaired the vulnerability at 12:37, and resumed withdrawals at 17:26. This incident only affected one account; the balances, positions, and orders of other users were not impacted. arcus and labs have used the company's reserve funds to fully cover the losses. The platform is currently cooperating with blockchain investigation agencies to trace the stolen funds and will assist law enforcement authorities if necessary.
