Chess.com

A data breach involving the popular online chess platform Chess.com was reported in late 2023. The incident involved the exposure of approximately 1.2 million user records which were circulated on various hacking forums. The leaked data set includes sensitive user information such as email addresses, internal usernames, and real names. Additionally, profile-specific details were compromised, including registration dates, country of origin, profile links, skill levels, chess ratings, and subscription statuses. The breach likely resulted from scraping or an unauthorized database export rather than a direct infrastructure compromise, as no passwords were reported in this specific data set.
