Yahoo says hackers stole information from over 1B accounts

National/World

NEW YORK (WATE/AP) — Yahoo says it believes hackers stole data from more than one billion user accounts in August 2013.

The Sunnyvale, California, company says it’s a different breach from the one it disclosed in September, when it said 500 million accounts were exposed. That new hack revelation raises questions about whether Verizon will try to change the terms of its $4.8 billion proposed acquisition of Yahoo.Previous story:Yahoo says hackers stole info in 500 million user accounts

Troublingly, Yahoo’s chief information security officer Bob Lord says that the company hasn’t been able to determine how the data from the one billion accounts was stolen. “We have not been able to identify the intrusion associated with this theft,” Lord wrote in a post announcing the hack.

Yahoo says the information stolen may include names, email addresses, phone numbers, birthdates and security questions and answers. The company says it believes bank-account information and payment-card data were not affected.

What can users do to protect their account?

Yahoo encourages users to visit their Safety Center page for recommendations on how to stay secure online. Some important recommendations they are re-emphasizing include:

  • Change passwords and security questions and answers for any other accounts on which you used the same or similar information used for your Yahoo account;
  • Review all of your accounts for suspicious activity;
  • Be cautious of any unsolicited communications that ask for your personal information or refer you to a web page asking for personal information;
  • Avoid clicking on links or downloading attachments from suspicious emails; and
  • Consider using Yahoo Account Key, a simple authentication tool that eliminates the need to use a password on Yahoo altogether.
