Art and crafts retailer Michaels Stores confirmed Thursday that it about 3 million payment cards were affected by a data breach that ran from May 2013 to February 2014 in its Michaels and Aaron Brothers stores.
Retailers have been under fire for data breaches. Target late last year was hit with a large data breach that hurt the company's earnings and standing with customers.
The company said in January it learned of the breach and hired security firms to investigate. Michaels also said that it has contained the incident and the malware isn't a threat.
