Kmart stores hit by data breach

RBR Staff Writer Published 13 October 2014

Sears Holdings announced a data breach at its wholly owned subsidiary, Kmart stores, the latest in a series of computer security breaches to hit US retailers in recent months.

Kmart, which has about 1,200 stores across the US, said its investigation to date indicates that the breach started in early September.

According to Kmart's security experts, its store payment data systems were infected with a form of malware that was undetectable by current anti-virus systems. Though the company has removed the malware, however, it believes certain debit and credit card numbers have been compromised.

Based on the forensic investigation to date, no personal information, debit card PIN numbers, email addresses and social security numbers were obtained by those criminally responsible. There is also no evidence that kmart.com customers were impacted, the retailer said.

Kmart said it would be offering free credit monitoring protection to further protect its members and customers who shopped with a credit or debit card in its stores during the month of September through October 9, 2014.

Kmart said that it is working closely with federal law enforcement authorities, its banking partners and IT security firms in this ongoing investigation and is also deploying further advanced software to protect customer information.
