UPCX suffered unauthorized access, and about $70 million of UPC tokens were abnormally outflowed

Mars Finance News, on April 1st, the Japanese open-source payment system UPCX announced that it discovered unauthorized activities involving project management accounts. As a preventive measure, immediate actions are being taken to ensure platform security. UPCX's deposit and withdrawal functions are temporarily suspended. User assets remain safe and unaffected. Previously, Cyvers Alerts warned that suspicious transactions involving UPCX were detected. It appears that someone gained access to address 0x4C....3583E, upgraded the "ProxyAdmin" contract, and executed the "withdrawByAdmin" function, resulting in the transfer of 18.4 million UPC tokens (approximately $70 million) from three different management accounts.
