Yahoo's parent company says 2013 data breach affected every customer account

Posted:

(CNN) - It now appears a data breach that affected Yahoo in 2013 was much worse than originally thought.

In 2016, Yahoo's parent company, Verizon, said the breach affected roughly 1 billion accounts. Verizon said Tuesday that it has since received new intelligence and new forensic information. Now, the company said the breach in August 2013 affected every customer account that existed at the time, which includes 3 billion accounts across Yahoo's email services, Tumblr, Flickr and Fantasy.

Yahoo, in talking about the hack in 2016, said names, passwords and email addresses were breached but not financial information.
