Yahoo confirmed today that at least 500 million of its user accounts were stolen as part of a data breach in 2014. Yahoo believes that a "state-sponsored" actor is responsible for the breach. Information stolen may include names, email addresses, telephone numbers, dates of birth, hashed passwords, and security questions and answers. For more information, see Yahoo's statement on the breach.
