Some Polymarket users reported that their accounts logged in via Google have been attacked.

Golden Finance reported that, according to Cointelegraph, some Polymarket users complained that their account logged in through Google was attacked, and their USDC balance was stolen. Attackers used the 'proxy' function to steal funds, but only a few Google login users were affected. Users using browser extension wallets such as MetaMask and Trustwallet were not affected. Users found their balance empty after depositing funds, and Polymarket officials have launched an investigation. Currently, the total loss for users has exceeded $5,000.
