We wanted to inform you of a serious security breach at Yahoo!
Earlier today, Yahoo! issued a press release stating that 500 million users' accounts were breached. Account information accessed includes usernames and passwords, security questions and answers and other confidential user information.
Yahoo! said in the press release that:
A recent investigation by Yahoo! Inc. has confirmed that a copy of certain user account information was stolen from the company's network in late 2014 by what it believes is a state-sponsored actor. The account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (the vast majority with bcrypt) and, in some cases, encrypted or unencrypted security questions and answers. The ongoing investigation suggests that stolen information did not include unprotected passwords, payment card data, or bank account information; payment card data and bank account information are not stored in the system that the investigation has found to be affected. Based on the ongoing investigation, Yahoo! believes that information associated with at least 500 million user accounts was stolen and the investigation has found no evidence that the state-sponsored actor is currently in Yahoo's network.
If you were a victim of the attack, we encourage you to review these steps you can take to file a report and help protect yourself from identity theft.
Yahoo! also recommends – as we do, too – that users take advantage of two-factor authentication to provide an extra layer of security to their Yahoo! accounts.
