What was exposed

  • 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.
