Financially-troubled Sears Holdings has confirmed that hackers recently breached the credit card processing system of some of its Kmart stores, and that the cards of some customers could have been compromised.
But Sears said that neither Sears nor Kmart were deeply impacted by the attack — the second of its kind since 2014.
Even so, cyber analysts routinely tell consumers to check their credit card statements when such a breach happens.
The latest breach against Kmart was first reported, in an extensive way, by journalist Brian Krebs, who operates one of the most widely read cybersecurity sites on the web.
Kmart isn’t the only major chain hit by hackers. Over the Memorial Day weekend, Chipotle acknowledged that most of its stores had been hit by hackers using malicious software.
