The new owner of Yahoo, Verizon, has announced that the massive data breach at Yahoo in 2013 was far more extensive than previously thought, affecting all of its 3 billion user accounts.
Late last year, it had said that the attack compromised 1 billion accounts - which already made it the largest data breach ever. Three months before that, the company also disclosed a separate attack, which had occurred in 2014, that had affected 500 million accounts.
"Based on an analysis of the information with the assistance of outside forensic experts, Yahoo has determined that all accounts that existed at the time of the August 2013 theft were likely affected," Yahoo disclosed Tuesday.
"It is important to note that, in connection with Yahoo's December 2016 announcement of the August 2013 theft, Yahoo took action to protect all accounts. The company required all users who had not changed their passwords since the time of the theft to do so," the statement read.
