Really? Yahoo has (or had) 3 BILLION customers? That seems strange. But in any case…
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. Yes, that’s a delay iof 4 years before telling customers that their accounts and passwords had been hacked.
That’s three billion accounts, including email, Tumblr, Fantasy and Flickr — or three times as many as the company initially reported in 2016.
If you still have a Yahoo account, please ask yourself, “Why?”
