Chess.com (2023) data breach
1,274,077 accounts · breached November 8, 2023
What happened
In November 2023, over 800k user records were scraped from the Chess.com website and posted to a popular hacking forum. The data included email address, name, username and the geographic location of the user. A further 446k scraped records were later provided and added to HIBP.
What data leaked
- Email addresses
- Geographic locations
- Names
- Usernames
What to do if you had an account
- Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
- Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
