Yahoo Reveals That Its 2013 Hack Affected All of Its 3 Billion Accounts

Yahoo announced this week that the data breach the company suffered in 2013, actually affected all of the company’s 3 billion accounts.

According to a securities filing in May from the company, Yahoo has already been hit with 41 consumer class-action law suits in U.S. federal and state courts.

The latest figure on how many people were affected triples the earlier estimate and makes it the largest hack in history.

It was this past December that Yahoo said the hack had affected 1 billion accounts. The data breach then was considered so huge that Yahoo had to cut the price of its assets when selling them to Verizon. Verizon decreased its offer for Yahoo’s assets by $350 million after the hack was revealed.

According to “recently obtained new intelligence,” the company said on Tuesday that all accounts had been affected. The company reassured however that the investigation showed that no passwords in clear text, payment card data or bank account information was included in the data breached.

According to Mark Molumpy, the lead counsel in a shareholder derivative lawsuit against

Yahoo announced that it is sending email notifications to additional affected user accounts.
