SPOKANE, Wash. -

Target, one of the nation's largest retailers, has been hacked, millions of credit and debit cards exposed and if you've shopped at Target since Black Friday that list includes you.

This impacts anyone who has swiped their card at any Target store across the country. Online purchasers have not been compromised, but overall 40 million people need to take a closer look at their bank accounts.

It's the worst time of the year for something like this to happen with consumers doubting a store's security because a hacker shoplifted Target's customer data. The stolen data includes customer names, credit and debit card numbers, expiration dates and the three-digit security codes.

Chelsea Maguire with the Better Business Bureau in Spokane suggests checking your bank account several times a day if you've shopped at Target recently.

"This is a very big issue and they need to be concerned, but using a credit card is still one of the safest ways to transfer money," Maguire said.

That way you can also see if there are any discrepancies to dispute a fraudulent charge right away.

"Businesses really need to take this message. All businesses large and small, how important it is to protect the data of their customers," Maguire said.

The Target breach is similar to the URM breach here in the Inland Northwest last month.

In a statement on the Target website the company said they are working with law enforcement to resolve the issue. They've also hired a third-party forensics firm to conduct an investigation as well.

If you have shopped at Target since Black Friday and find what you think is a fraudulent charge on your account you need to first call your bank and tell them what's happened. You can also Target at 1-866-852-8680.
