What was exposed
Chat logs: The text of conversations you had in an app or website chat, including direct messages, group chats and support chats, sometimes with attached files, images and voice notes.
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.
Geographic locations: A general location recorded on your account, such as a country, state, city, postcode or region, either typed in by you or estimated from your IP address.
IP addresses: The network addresses your devices used when you signed up, logged in or posted, recorded by almost every website in its access logs.
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.
Private messages: Direct messages, chats and inbox conversations on a platform, which can include photos, links, attachments, addresses, phone numbers and details you shared expecting only one person to read.
User statuses: A label describing your account state, such as active, inactive, verified, suspended, banned, premium or pending verification.
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.
