How many victims? The company did not indicate how many stores were affected or how many customer credit cards were potentially compromised but said the malware had been removed.

What information was breached? The affected systems contained payment card customer names, numbers and expiration dates. The company has no evidence that other customer personal information, such as social security numbers, PINs and email addresses, was compromised as a result of this malware infection.

When did it happen? Sears Holdings Corp. announced that it detected a data breach at its Kmart stores that began in September 2014, affecting certain customers’ credit and debit card accounts.

What they’re saying: “Our Kmart store payment data systems were infected with a form of malware that was undetectable by current anti-virus systems,” Sears Holdings said in a statement.

Kmart has apologized to the public and said it was in the process of working with federal authorities, banking partners and security firms in an ongoing investigation into the hacking. The Secret Service was among the agencies in the probe, a spokesman said. Earlier this summer, the Secret Service estimated that nearly 1,000 American merchants were affected by this kind of attack, and that many of them may not even know that they were breached.
