Polymarket Front-End Hack Drains $3.1M PUSD From 11 Wallets on June 27

GateNews
Security IncidentsDaily Crypto News
According to blockchain intelligence firm AMLBot, hackers stole approximately $3.1 million in PUSD from 11 Polymarket user wallets on June 27 through malicious code from a compromised third-party vendor delivered via the platform's front end. The attack used hidden wallet approval prompts to route funds to attacker-controlled wallets. Security researchers identified the breach as a front-end supply chain attack rather than a smart contract exploit. Polymarket said on June 25 that it removed the affected dependency and committed to fully refunding impacted users.
