Polymarket Rejects Dark Web Claims of 300,000+ Customer Data Breach

According to posts on dark web forums, Polymarket denied allegations that a hacker stole over 300,000 customer records and 10,000 user profiles. The platform stated that the data referenced by the attacker was already publicly accessible through its open APIs and on-chain blockchain records, not the result of unauthorized access.

Security researchers and cybersecurity experts questioned the breach allegations, with some suggesting the data was scraped from public sources rather than leaked from internal systems. Vladimir S, chief security officer at Legalblock, said the situation appeared to be someone collecting publicly available information and falsely presenting it as a database leak.
