GoKawiil7.3 Million Chess.com Profiles Leaked, Likely From Data Scraping Not a Breach
A 15.5 GB file containing over 7.3 million Chess.com user records surfaced for free on two data-leak forums, with no ransom attached. Analysis of the archive found genuine, recent Chess.com data including emails, usernames, ratings, and subscription status, but no passwords or payment details, pointing toward large-scale scraping rather than a server intrusion.
GoKawiil's interpretation of the reporting above, not reported fact.
The presence of internal Google Ad Manager audience tags, fields not exposed through Chess.com's public API, suggests the scrapers may have pulled from more than just public profile pages, possibly touching marketing infrastructure. Even without passwords, exposed emails and real names tied to chess ratings and subscription tiers create strong material for phishing and targeted social engineering against millions of users.
- 7.3 million Chess.com records leaked for free across two data-leak forums.
- Data includes emails, usernames, ratings and internal ad-targeting fields, but no passwords or payment info.
- Evidence points to scraping rather than a direct breach of Chess.com's servers.
