Polymarket resumed trading after a halt of about one hour following a reported attack, according to monitoring cited by Odaily and Bitcoin News. The attacker was said to have exploited still-active user sessions, allowing positions to be sold directly through the Polymarket system and funds to be withdrawn. The incident was reportedly linked to a compromise involving a DebugBear website performance monitoring script. That script was said to have been replaced with malicious code, which users’ browsers treated as trusted. After services came back online, Polymarket said it would compensate affected users. The case has also been referred to law enforcement authorities in the United Kingdom. No additional figures on losses or the number of affected users were disclosed in the source material.
