"We recommend that you remain vigilant by reviewing your account statements for unauthorized charges. If you believe your payment card may have been affected, you should immediately contact your bank or card issuer."
including Target, Michaels was working with federal law enforcement and third-party security experts to determine the origin and scope of the breach.
"After weeks of analysis, we have discovered evidence confirming that systems of Michaels stores in the United States and our subsidiary, Aaron Brothers, were attacked by criminals using highly sophisticated malware that had not been encountered previously by either of the security firms," Rubin said, in a statement issued last week.
Among the findings of Michaels' investigation are:
- The affected systems contained certain payment card information, such as payment card number and expiration date, about both Michaels and Aaron Brothers customers. There is no evidence that other customer personal information, such as name, address or PIN, was at risk in connection with this issue.
- Regarding Michaels stores, the attack targeted a limited portion of the point-of-sale systems at a varying number of stores between May 8, 2013 and January 27, 2014. Only a small percentage of payment cards used in the affected stores during the times of exposure were impacted by this issue. The analysis conducted by the security firms and the Company shows that approximately 2.6 million cards may have been impacted, which represents about 7% of payment cards used at Michaels stores in the U.S. during the relevant time period.

- Regarding Aaron Brothers, the Company has confirmed that between June 26, 2013 and February 27, 2014, 54 Aaron Brothers stores were affected by this malware.
