Yahoo suffered a data hack in 2013 that put one billion user accounts at risk. The data stolen from the attack included birthdays, phone numbers, encrypted security questions, names, and encrypted passwords.

The company, who identified the 2013 attack after dealing with a similar attack in 2014, says they don’t know how many users were victimized. As a precaution, Yahoo invalidated all user security questions and forced them to reset their passwords. Critics of Yahoo blamed their lack of attention to security in recent years for making them an easy target.
