On Thursday, Oct. 9, 2014 Kmart's IT team detected that the Kmart store payment data system had been breached and immediately launched a full investigation working with a leading IT security firm. The security experts report that beginning in early September, the payment data systems at Kmart stores were purposely infected with a new form of malware (similar to a computer virus). This resulted in debit and credit card numbers being compromised.
