One of the world’s largest and longest-running Internet sites had bad news Thursday.

Yahoo! revealed user account information was stolen from the company’s network in 2014 by what it believes to be a state-sponsored actor, and the information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords, and in some cases, encrypted or unencrypted security questions and answers.

The breach affected 500 million users, according to Chief Information Security Officer Bob Lord.

If there’s a silver lining, none of the stolen information included unprotected passwords, payment card data, or bank account information, as that data was not stored in the system that was impacted, Lord said in a statement.

“An increasingly connected world has come with increasingly sophisticated threats,” Lord said in the statement. “Industry, government and users are constantly in the crosshairs of adversaries. Through strategic proactive detection initiatives and active response to unauthorized access of accounts, Yahoo will continue to strive to stay ahead of these ever-evolving online threats and to keep our users and our platforms secure.”
