Polymarket Rejects Breach Claims Amid 300K Record Leak Reports The platform denies any hack, while researchers point to API flaws, undocumented endpoints, and exposed datasets shared on a cybercrime forum. Key Highlights Polymarket says the reported 300K-record “leak” consists of publicly accessible on-chain and API data, with no private information compromised. The alleged dataset was reportedly compiled using undocumented API endpoints, weak pagination controls, and misconfigurations, alongside an exploit kit shared on a cybercrime forum. While Polymarket calls the claims misleading, critics argue large-scale aggregation of public data, and the methods used, raise security and privacy concerns that remain unaddressed. Prediction market platform Polymarket has denied claims of a security breach after reports surfaced that more than 300,000 records and an exploit kit were leaked on a cybercrime forum. #PolymarketDeniesDataBreach
