What was exposed
Browser user agent details: A short text string your browser sends to every website, naming the browser, its version, the operating system and often the device type, for example Chrome on Windows or Safari on an iPhone.
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.
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.
Physical addresses: Your residential, postal, billing or delivery address, stored by retailers, utilities, banks, government services and almost any company that sends you something.
Salutations: The title used before your name, such as Mr, Mrs, Ms, Mx, Dr or Rev, stored so letters and emails can address you formally.
