On Wednesday, December 14th Yahoo Inc. revealed that it suffered a security breach back in 2013 that compromised more than one billion accounts. This however, is different than the breach that occurred in September of 2014 where over 500 million user accounts had been hacked. These two attacks are the largest breaches of one company’s computer network.

The newly disclosed 2013 attack involved sensitive user information, including names, telephone numbers, dates of birth, encrypted passwords and unencrypted security questions that could be used to reset a password.

If you have a Yahoo account, what should you do now? How do you know if your personal information was stolen? To be on the safe side, you should assume your personal information was stolen. Yahoo said that it notified potentially affected users but this was a huge breach and similar attacks happen all of the time.

Here are a few of the steps you should take now to ensure your information stays secure:

  1. Change Your Passwords: This step is an absolute must. It is always essential to change passwords for the sites that contain sensitive information like financial, health or credit card data. Take a look at previous blog post I’ve written on how to create strong passwords.

  2. Utilize Additional Security Features: Unfortunately, passwords are not enough to keep you safe. If a site offers additional security features like a two-factor authentication, absolutely take advantage of this increased level of security.

  3. Keep an Eye on Your Account: While it’s hard to say exactly what you should be looking for, keep an eye out for things that do not look normal on your account. Check your sent messages to make sure there aren’t emails that you didn’t send. Don’t click on any links from emails that look shady and don’t provide any personal information or passwords if asked.

It is important that you understand that breaches and attacks are inevitable, hackers are always trying to find a way to break in. If you don’t feel like you or your organization is where you need to be from a security standpoint, then it’s time for a conversation with our security experts.
