Kmart data breach: What you need to know

In a letter posted on, the company acknowledged that Kmart store payment data systems were infected with a malicious code that anti-virus systems didn’t detect.

Once identified, the malicious code was removed and Kmart says its payment data systems are safe again.

Kmart stresses that no personal identifying information, such as names, addresses, Social Security numbers, birth dates and email addresses, was obtained by the criminals.

However, the retailer admits that some credit card numbers have been compromised.

Kmart says all of its stores had EMV “Chip and Pin” technology enabled during the time of the breach. The company believes the exposure to data that can be used to create counterfeit cards is limited.

At this point, there’s no evidence that debit personal identification numbers (PIN) were stolen.

Check your statements immediately!

Kmart is urging customers to carefully review and monitor their debit and credit card account statements. Always report any suspicious charges to your payment card issuer immediately.


Another tip: See if your credit card company allows you to sign up for text alerts whenever a purchase is made.
