What happened
In early 2023, over 200M records scraped from Twitter appeared on a popular hacking forum. The data was obtained sometime in 2021 by abusing an API that enabled email addresses to be resolved to Twitter profiles. The subsequent results were then composed into a corpus of data containing email addresses alongside public Twitter profile information including names, usernames and follower counts.

What was exposed
Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
Names: Your first name, surname and sometimes middle name or initials, as you gave them when you signed up. It appears in almost every breach because nearly every account asks for it.
Social media profiles: Usernames, profile URLs or handles for social networks such as Facebook, Instagram, X, TikTok, LinkedIn or Discord, stored alongside another account.
Usernames: The handle or login name you chose for an account, which may be public on forums, games and social platforms or used privately to sign in.
