What was exposed
Device information: Technical details an app or website recorded about your device: make and model, operating system version, screen size, language, carrier, and sometimes the device name or advertising ID.
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.
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.
Partial credit card data: Fragments of a payment card rather than the full number, typically the first six or last four digits, the card brand, the expiry date or the cardholder name.
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.
