Yahoo Leaks 500 Million User Accounts
Few days ago Yahoo confirmed leakage of 500 million users account details, which may include names, email addresses, telephone numbers, dates of birth, passwords, and, in rare cases, security answers.
As Yahoo folks said, the bank account information and payment cards data have not been affected after the hack, and the company doesn’t store payment details in its system.
What to do if you use Yahoo?
Step #1. Change your password. That’s the standard action to prevent leakage of your personal information after the hack. Use a separate password for each account and make it strong.
Step #2. Change the answers to security questions. The same applies to other accounts that you use.
As the official Yahoo statement says:
Yahoo is notifying potentially affected users and has taken steps to secure their accounts.
These steps include invalidating unencrypted security questions and answers so that they cannot be used to access an account and asking potentially affected users to change their passwords.
During the recent years, Yahoo has been the target for hackers and has changed 4 chief information security officers between 2013-2015. And the recent hack took place in late 2014. It means that your accounts may had been hacked back in 2014, but we learned about it only now.
