A newly discovered data breach exposed the private information of more than 1 billion Yahoo users. The information theft in 2013 is distinct and twice as large as the 2014 hack Yahoo disclosed earlier this year. Data stolen include names, email addresses, telephone numbers, dates of birth, and passwords.
Better for safety:
-Change your password, security questions and answers for any other accounts on which you used the same or similar information used for your Yahoo account.
-Review your accounts for suspicious activity (e.g., unfamiliar login).
Be cautious of any unsolicited communications that ask for your personal information or refer you to a web page asking for personal information.
-Avoid clicking on links or downloading attachments from suspicious emails.
-Consider using Yahoo Account Key, a simple authentication tool that eliminates the need to use a password altogether.
