Prediction market Polymarket has suffered a major security breach, with nearly 1,000 accounts compromised and over $2.6 million lost. Blockchain analyst Conor Grogan disclosed that a total of 995 accounts were affected, with losses amounting to approximately $2.65 million. The two largest individual losses were $341,000 and $307,000, respectively. The attackers have converted all stolen funds into Polygon's native token, POL, possibly to prevent the funds from being frozen. Polymarket has confirmed that the attack originated from the compromise of a third-party service provider and has suspended trading, pledging to fully reimburse all affected users.
