The Wall Street Journal: Yahoo says information on at least 500 million user accounts is stolen

Yahoo Inc. on Thursday disclosed a massive security breach affecting at least 500 million users as the beaten-down internet company works through the sale of its core business.

Yahoo YHOO, +0.39% said a copy of certain user account information—including names, email addresses, telephone numbers, dates of birth, hashed passwords and, in some cases, encrypted or unencrypted security questions and answers—was stolen from the company’s network in late 2014 by what it believes is a state-sponsored actor.

Yahoo said it is notifying potentially affected users and has taken steps to secure their accounts. The company, which is working with law enforcement, said the ongoing investigation indicates that stolen information didn’t include unprotected passwords, payment card data, or bank account information.
