Chess.com Leak Exposes 7.3M Users, Evidence Points to Scraping

A breach exposing 7.3 million Chess.com user records was posted for free on data-leak forums, containing usernames, email addresses, names, locations, and chess ratings, but no passwords or payment data. Technical analysis confirms the data is genuine and recent, but evidence strongly suggests it came from large-scale scraping rather than a server breach, including the presence of internal Google Ad Manager audience tags and data collected across nine consecutive days in daily batches. Users need not be overly concerned about payment fraud since financial information was not compromised.
