Sears Holdings Corp.’s Kmart discount chain, the latest victim of hacker attacks on retailers, said it detected a security breach this week and is investigating the incident with law enforcement officials.
The retailer’s information-technology team identified the breach on Oct. 9 and is working with a top security firm to assess the incursion, which happened in early September, Kmart said in a filing yesterday. Customer payment-card information was probably exposed by the attack.
