An epic and historic data breach at Yahoo in August 2013 affected every single customer account that existed at the time, Yahoo parent company Verizon said on Tuesday. That's three billion accounts -- including email, Tumblr, Fantasy and Flickr -- or three times as many as the company initially reported in 2016. Verizon revised the number of breached accounts to three billion after receiving new information. Yahoo will send emails to the additional affected accounts. In any breach it's safe to assume the number of affected accounts will be adjusted, he said.
