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.
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.
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.
