Today Yahoo has disclosed that they have found out that there was another recent hack committed against their systems.

They revealed this news today, stating that more than one billion user accounts had been affected by the attack that dates back to 2013. They say it appears separate from the breach that they disclosed in September, which affected 500 million accounts in 2014.

Yahoo has said that names, phone numbers, passwords, and email addresses were stolen, but bank and payment data were not stolen.

They also stated that they are working closely with the police and authorities about this data breach, which not only included personal information but also “unencrypted security questions and answers”, so you should be sure to change your password and security questions and answers to any service that is in any way linked to the email that you used with Yahoo.

This is not only bad news for the one billion people who were affected by this attack, but it is also bad news for Yahoo themselves.

Yahoo is on the verge of being acquired by Verizon for $4.8bn, however, it is possible that this might suffer as a result.

We will update you about this if we hear more news.
