Michaels Stores Inc. announced in a press release Thursday that as many as 2.6 million payment cards used at Michaels and Aaron Brothers craft stores may have been affected by a security breach. They say they have so far received "limited" reports of fraud.
A criminal attacked the largest arts and crafts chain in the U.S. using sophisticated malware. The company learned of a possible data security breach in January but did not discover the details until after several months of investigation. Michaels Stores said they had identified and fully contained the incident.
