Polymarket halts trading after 'security incident' siphons $2.65 million in minutes

Polymarket halted trading after a security incident compromised a third-party provider (Debugbear), resulting in $2.65 million siphoned from users' wallets in over 900 transactions. The attack affected Polymarket's U.K. platform but not U.S. users; the company said it will fully reimburse affected traders and referred the matter to British authorities. This is the second major security incident for Polymarket in months, following a $3.1 million phishing attack in June.
