Confirmed 1 billion Yahoo accounts hacked

Yahoo has confirmed the theft of data linked to 1000 million user accounts. This unauthorized access took place in August of 2013, being a different case than the data theft that suffered at the end of 2014 and in which the data of 500 million accounts were stolen. Among the data stolen this time would be personal information such as birth dates, email addresses, phone numbers, hashed passwords (using MD5)   and, in some cases, encrypted or unencrypted security questions and answers. According to Yahoo's investigation, data filtering does not include clear passwords or bank details of any kind. Yahoo is notifying affected users and requesting a change of password.
