What was exposed
Bios: The free text about me section you wrote for a profile on a dating app, forum, social network, gaming platform or professional site.
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.
Passwords: The secret you use to sign in, stored by the breached service either in plain text, in a scrambled form called a hash, or encrypted. How it was stored decides how quickly it can be recovered.
Phone numbers: Your mobile or landline number, collected at signup for contact, delivery updates, marketing and two-factor codes.
Social media profiles: Usernames, profile URLs or handles for social networks such as Facebook, Instagram, X, TikTok, LinkedIn or Discord, stored alongside another account.
