Arcus Loses $2.23 Million Due to Accounting Flaw, Fully Reimbursed

Decentralized exchange platform Arcus disclosed that on November 10, an accounting flaw was discovered that allowed users to withdraw funds they were not entitled to. Arcus detected and fixed the flaw within an hour, and user balances were unaffected, with trading and withdrawals proceeding normally. The report indicated that at 11:07 AM on November 10, a newly created account exploited the flaw to record a balance far exceeding its actual holdings and requested a withdrawal, resulting in approximately $2.234 million USDG being withdrawn on-chain, while another $3 million withdrawal request was intercepted and canceled. Arcus Labs has fully reimbursed the shortfall from the company treasury and is working with blockchain investigators to trace the funds, while also publishing the attacker's initial address and requesting exchanges and service providers to flag the related funds.
