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.
Homepage URLs: The personal website, blog, portfolio or social profile link you added to a forum, developer site or community profile.
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.
