Yahoo believes, based on third party forensic evidence, that someone stole user data from one billion Yahoo accounts in 2013, according to a press release from the company. This theft is separate from the hack of 500 million accounts disclosed in September and Yahoo’s surveillance for the US government.
The company has not been able to identify the perpetrators of the billion-account hack, the press release said. Yahoo is requiring users to change their passwords and password recovery questions.
The data may have included “names, email addresses, telephone numbers, dates of birth, hashed passwords (using MD5) and, in some cases, encrypted or unencrypted security questions and answers.” Credit card info was not affected, according to Yahoo.
