Target Credit Card breach

Target is offering a store discount and free credit monitoring after what's being called the second-largest credit card breach in U.S. history.

For many of us, the holiday season means our credit card bills are piling up nonstop, but the recent security breach at Target could have some shoppers worried.

Target says it's fixed the problem that allowed credit and debit card information on as many as 40 million accounts to be stolen. It says credit card holders can continue to shop at its stores.

One security analyst says it's "alarming" that Target could experience a data breach putting up to 40 million credit and debit card accounts at risk, considering all of the security the store chain has in place.

Target says that about 40 million credit and debit card accounts may have been affected by a data breach that occurred just as the holiday shopping season shifted into high gear.

The Secret Service says it is investigating a credit- and debit-card data theft at Target stores.
