Security breach at Michaels stores affects nearly 3 million cards

DENVER — You might shop for supplies for school projects at Michaels, but the company’s computers were hacked and now millions of credit card numbers might be at risk.

Nearly 3 million cards, or about 7 percent of all debit and credit cards used at the stores nationwide, might be affected. But store officials say they have the breach under control.

They realized it when banks started reporting fraudulent charges. The hackers have access to card numbers and expiration dates, but there’s no evidence that PINs were at risk.

This comes after last year’s security breach at Target that affected 40 million debit and credit cards.

The breach at Michaels occurred between May 8 and Jan. 27. The company also owns Aaron Brothers. The breach affected 54 of those stores from June 26 and Feb. 27

If you suspect your card has been compromised, the best thing you can do is cancel it right away. Ask your bank about policies for covering charges you didn’t make.
