Yahoo now says that all of its 3 billion users were affected in the 2013 breach, disclosed last year, tripling the total number of victims initially reported. In a filing with the Securities and Exchange Commission (SEC) that itself disclosed a massive cyberattack last month, Verizon that now owns Yahoo revealed that “all Yahoo user accounts” were compromised in the biggest breach we have seen so far.

Last year, Yahoo reported that around 1.5 billion accounts of over 1 billion users had been compromised by a data breach that originally occurred in 2013. The company had disclosed the massive data breach during the final days of its acquisition by Verizon. The new owner of Yahoo now reveals that actually the company had managed to compromise every single account. This puts the total number of affected accounts at around 3 billion, about 40% of the world’s total population.
