Almost exactly a year after Yahoo announced they suffered the largest data breach to-date, officials corrected the estimated number of users affected in a statement released on October 3rd. The initial estimation, which was made when they first announced their data breach in September 2016, was that the details of 500 million users were stolen. Three months later, Yahoo upped their assessment to one billion users. However, Yahoo is now telling users that virtually everyone who has a Yahoo account has had their data stolen. That’s correct, all THREE BILLION users have had their sensitive data stolen.
