(WHNT) – Michaels says a security breach at its stores lasted eight months and affected about three million customers.
The news comes three months after the largest U.S. crafts chain told customers it learned of a possible hack. It’s been investigating since then.
Some credit and debit card numbers and expiration dates were compromised.
However, the company said there is no evidence information such as customer names or PINs were stolen.
The breach affected about seven percent of card transactions at its stores from early May 2013 to late January 2014.
The Michaels subsidiary Aaron Brothers was also hacked.
Information from another 400,000 cards was potentially stolen at the Aaron Brothers stores between late June 2013 and late February 2014.
The initial Michaels announcement came just weeks after Target also disclosed it was hacked.
