UPCX halts transactions after $70m security breach

The open-source payment platform UPCX suspended transactions following an unauthorized withdrawal of approximately $70 million in digital assets. Blockchain security firm Cyvers identified the breach on April 1, flagging suspicious activity involving 18.4 million UPC tokens. Cyvers reported that an attacker gained control of a UPCX administrative wallet and modified its ProxyAdmin contract. This enabled the execution of a withdrawal function, leading to fund transfers from three different management accounts. The stolen tokens remain in a single wallet, with no observed attempts to swap or liquidate the assets.
