Hackers infiltrated Polymarket’s comment section and inserted phishing links that compromised the credentials of users logging in via email. The attack allowed them to inject malicious scripts and steal funds.
Senior trader @25usdc confirmed losses exceeding $500,000 and warned users to avoid external links in comments. The company stated that the losses affected only users, not the protocol or institutional funds.
The platform’s total value locked (TVL) dropped by around 12% within 24 hours, reflecting the impact of the incident on user confidence. Ethereum wallets were particularly affected, exposing weaknesses in the Web2 layer of the DeFi ecosystem.
Researcher @zachxbt described the attack as “simple but effective” and urged stronger security practices. Polymarket is implementing mitigation measures and reviewing the integrity of its platform.
