Another data breach has hit SuperValu, the company said Monday.

In a statement, SuperValu said some cardholder information from payments at checkout lanes was possibly stolen by hackers using malware. The malware potentially captured account numbers, expiration dates, and names from cards used at checkout lines at Cub Foods stores in Hastings, Shakopee, White Bear Lake and the Roseville store at Har Mar Mall.

Cardholder data may have been stolen from payment cards used in those stores from Aug. 27 through Sept. 21.

It is the second data breach for Supervalu this year. In August the company announced that between June 22 and July 17, cardholder information may have been stolen from transactions in more than 200 stores across the country. SuperValu is still investigating that incident and hasn't determined whether any cardholder data was in fact stolen in the breach.

The company says the two intrusions are separate.

"We've taken measures to install enhanced protective technology that we believe significantly limited the ability of this malware to capture payment card data and we will continue to make these investments going forward," President and CEO Sam Duncan said in a statement.

In light of the most recent breach, SuperValu says it took immediate steps to attempt to eradicate the malware and has contacted both federal authorities and major payment card companies about the breach.

The company said customers may call with questions: (855) 731-6018.
