Kmart is the latest retailer targeted by a data breach involving malware which may have compromised some customers’ payment-card information, the Associated Press reported.
Sears Holdings Corp., the holder of Kmart stores, said on Friday that Kmart’s information technology department had detected the breach of payment data systems on Thursday.
According to Bloomberg, the retailer is working with a top security firm to assess the attacks on private data, which started last month.
The store payment data systems were infected with a form of malware that was undetectable by current anti-virus,” according to Friday’s SEC filing. “Kmart was able to quickly remove the malware. However, Kmart believes certain debit and credit card numbers have been compromised.”
The AP reports that while Kmart wasn’t able to provide the number of cards affected, the company said it believes no personal information, debit card PIN numbers, email addresses and social security numbers were compromised.
