500 million users had their names, email addresses, phone numbers, birth dates, hashed passwords, and security questions and answers exposed following a previous breach of the company announced in September. Yahoo later revealed that they had known about the hack as early as 2014, however didn’t inform users until two years later.

This news story is still developing and will be updated.

Yahoo advises users to change their passwords and security questions.
