What was exposed
Dates of birth: Your full birth date, day, month and year, collected at signup for age checks, identity verification, insurance quotes, birthday offers or government services.
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.
Historical passwords: Passwords you used on an account before changing them, kept by a service in a password history so you cannot reuse them, or gathered from older breaches into combined lists.
Instant messenger identities: Usernames or IDs for messaging services such as Telegram, Discord, WhatsApp, Signal or Skype, or older services such as ICQ and AIM, stored in profile fields or contact records.
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.
Website activity: Records of your actions on a website or app, such as pages viewed, searches, clicks, downloads, logins, cart activity, IP addresses and timestamps.
