Hannaford Bros. Supermarkets is warning customers that their credit card information may have been compromised. The company said a network hacker broke into the firm's database, stealing credit card numbers, along with expiration dates.
Company CEO Ron Hodge says the attack has been contained.
"No personal information, such as names or addresses, was accessed. Hannaford doesn't collect, know or keep any personally identifiable customer information from transactions," Hodge said in a statement on the company's Web site.
The intrusion affected Hannaford stores, Sweetbay stores in Florida and certain independently-owned retail locations in the Northeast that carry Hannaford products.
"The stolen data was limited to credit and debit card numbers and expiration dates, and was illegally accessed from our computer systems during transmission of card authorization," Hodge said.
Hannaford said it is cooperating with credit and debit card issuers to ensure those customers who may be affected by the theft are protected. It said it has also alerted law enforcement authorities, and is working closely with them to help identify those responsible.
