On December 13th, 2016, Yahoo released a statement that more than 1 billion accounts were compromised in 2013. This is separate data breach from the 500 million accounts compromised in 2014. Yahoo says that the stolen user information included names, email addresses, telephone numbers, dates of birth, hashed password and in some cases, encrypted or unencrypted security questions. 

Here are some steps to insure your account is secure. 

  • Log in to that account and change your password. If possible, also change your username.
    • If you can't log in, contact the company. Ask them how you can recover or shut down the account.
  • If you use the same password anywhere else, change that too.
  • If you have any financial informational saved in your yahoo account, check your financial accounts for any charges that you don't recognize
