Security expert warns of new ransomware attack after massive Yahoo hack

INDIANAPOLIS, Ind. - This week, Yahoo announced a billion accounts were compromised in a data breach, and now one cyber security expert warns there's another cyber attack coming that could spread like wildfire.

Yahoo said the hack took place in 2013. Hackers may have access to your name, email address, telephone number, date of birth, and your security questions and answers. The good news is that hackers did not get access to social security numbers from compromised accounts.

Users should change their password, enable two-factor authentication and search through their emails to make sure they didn't send out sensitive information.

“Yahoo may not ask for your social security number, but your mom might in another state where you sent it through email," explained Kevin Mabry, CEO of Sentree Systems.

Mabry said hackers make about $50 for each name that comes with personal information like a social security number, which is why we are seeing so many data breaches.

He warns people should change their passwords often and backup important data on an external hard drive which can be disconnected from your device.

He also said hackers are working on a new cyber-attack that could compromise countless computers.

“If you get ransom attacked, they say ‘I will give you the key to unlock your computer, if you will send this ransomware exploit kit to two people.' And they want proof that you sent it. So you don’t have to pay any money, but they want to spread it. That’s something that’s coming out in 2017. Be cautious of that one.”

You should also look into freezing your credit. Here are directions from the Federal Trade Commission:

Contact each of the nationwide credit reporting companies:

You'll need to supply your name, address, date of birth, Social Security number and other personal information. Fees vary based on where you live, but commonly range from $5 to $10.

After receiving your freeze request, each credit reporting company will send you a confirmation letter containing a unique PIN (personal identification number) or password. Keep the PIN or password in a safe place. You will need it if you choose to lift the freeze.
