Verizon may soon want to change some details in their deal with Yahoo, as Yahoo just announced that they believe hackers stole data from more than one billion user accounts back in 2013.
This is a different breach than the one the company announced in September. That breach had 500 million accounts exposed.
According to Yahoo, the information stolen may include names, email addresses, phone numbers, birth dates and security questions and answers. The company does not believe that bank-account information and payment-card data were affected.`
