Massive Michael's security breach includes Milwaukee-area stores
BROOKFIELD -- A major security breach is affecting another retail chain, and thousands of shoppers in the state are at risk.
Michael's, the nation's largest arts and craft chain, confirmed the massive security breach Thursday, saying hackers stole credit and debit card numbers and expiration dates using what the company calls highly sophisticated malware.
The breach began in May 2013 and lasted through January 2014.
The store says there's no proof that PIN numbers were compromised.
There are stores scattered throughout southeastern Wisconsin, including Milwaukee, West Allis, Brown Deer and Brookfield.
Michael's is offering free identity theft protection and credit monitoring for all of its customers.
