Yahoo’s 2013 breach left 3 billion accounts exposed
Yahoo had originally said that one billion accounts were affected
If you had a Yahoo account in 2013, you were in fact affected by the huge data breach as the company has today revealed that all three billion accounts were exposed.
Yahoo had initially reported in December 2016 that one billion accounts had been affected but now a new statement said that the company is now providing notice to additional account member that had not been notified before.
Yahoo does stress that the latest investigation found that the stolen information did not include passwords in clear text, payment card data, or bank account information. However it does include names, email addresses, birthdays and phone numbers, as well as encrypted and unencrypted security questions and answers.
The statement said:" Subsequent to Yahoo's acquisition by Verizon, and during integration, the company recently obtained new intelligence and now believes, following an investigation with the assistance of outside forensic experts, that all Yahoo user accounts were affected by the August 2013 theft.
"While this is not a new security issue, Yahoo is sending email notifications to the additional affected user accounts. The investigation indicates that the user account information that was stolen did not include passwords in clear text, payment card data, or bank account information. The company is continuing to work closely with law enforcement."
