On March 13, a federal credit union filed a class action suit against a national retailer and parent company, alleging their actions during a September 2014 data breach injured credit unions, banks, and other financial institutions. Greater Chautauqua FCU v. Kmart Corp and Sears Holdings Corp., No. 15-cv-2228, (N.D.Ill. Mar.13,2015) The complaint contends that financial institutions (i) were required to, among other things, refund fraudulent charges, respond to a higher volume of customer complaints, and increase fraud monitoring efforts, and (ii) lost revenue due to a decrease in card usage after the breach was disclosed. The complaint alleges that the retailer failed to maintain adequate data security under applicable payment card industry standards, particularly in the wake of well-publicized data breaches at other retailers by third parties using similar techniques and malicious software. Moreover, the retailer failed to detect or notify customers for a period of at least five weeks. The complaint was filed in US District Court for the Northern District of Illinois, and alleges damages in excess of $5,000,000 for violations of the Illinois Personal Information Protection Act, the Illinois Consumer Fraud and Deceptive Business Act, and New York General Business Law, as well as negligence, and negligent misrepresentation and/or omission.
