Massive Data Breach Compromises 1 Billion+ Yahoo Users

Yahoo has confirmed that it has been the target of another massive data breach, this one stemming back to August, 2013. The newly discovered breach is in addition to the huge 2014 breach and impacts more than one billion Yahoo users.

The breach includes names, email addresses, phone numbers, dates of birth, MD5-hashed passwords, and security question answers. This latest hack makes Yahoo the victim of two of the largest data breaches in history.

If you have a Yahoo account, here are some steps you should take to secure your account:

  1. Update your passwords AND security questions/answers if you haven't done so since August 2013.
  2. Check if you have used your Yahoo password in other sites, and change the password and security questions for those accounts. (And, in the future, use different passwords for different services.)
  3. Be wary of unsolicited email asking for personal information.
  4. Be wary of unsolicited email attachments.
  5. Check your bank accounts for suspicious activity, particularly if you have used your Yahoo password on financial accounts.
