Polymarket front-end compromised through third-party vendor; about $3M of users' pUSD drained
Polymarket disclosed on 25 June 2026 that a breached third-party vendor let attackers inject malicious code into its website for some users. Users who interacted with the compromised front-end had their pUSD (Polymarket's USDC-backed stablecoin) drained; Bubblemaps estimated about $3M taken from fewer than 15 users, and the funds were converted to ETH. Polymarket removed the code and says it will fully refund affected users.
