A massive breach involving an ex-employee leaked detailed user profile data from roughly 2.87 billion Twitter accounts, combining new and previously exposed information. The dataset includes user metadata like IDs, screen names, follower counts, and tweets, increasing risks of phishing and impersonation. Although no sensitive information such as email addresses was found in the new data, the merge with past breaches presents a comprehensive user profile view. Twitter has not acknowledged the breach, which stands as the second-largest in history.
