Department store chain Sears Holding Corp and Delta Air Lines Inc said on Wednesday some of their customer payment information may have been exposed in a cyber security breach at software service provider.
Sears said it was notified of the incident in mid-March and the incident led to unauthorized access to the credit card information of under 100,000 of its customers.
Technology firm, which provides online support services for Delta, Sears and Kmart among other companies, found that a cyber security incident affected online customer payment information of its clients, it said.
The incident happened on or after Sept. 26, 2017 and was found and resolved on Oct. 12, the company said.
Personal details related to passport, government identification, security and SkyMiles information were not impacted, Delta said.
The No.2 US carrier said while a small subset of its customers would have had their information exposed, it cannot be said with certainty if their information was accessed and compromised.
Sears said its stores were not compromised and their internal systems were not accessed in the breach. There was no impact on the information of customers using a Sears-branded credit card, the retailer said.

Retailer Hudson’s Bay Co on Sunday disclosed that it was the victim of a security breach that compromised data on payment cards used at Saks and Lord & Taylor stores in North America.
One cyber security firm said that it has evidence that millions of cards may have been compromised, which would make the breach one of the largest involving payment cards over the past year, but added that it was too soon to confirm whether that was the case.
Toronto-based Hudson’s Bay said in a statement that it had “taken steps to contain” the breach but did not say it had succeeded in confirming that its network was secure. It also did not say when the breach had begun or how many payment card numbers were taken.
