Dairy Queen says that its payment systems were breached by hackers who may have gained access to customer names, credit and debit card numbers and expiration dates.
The ice cream and fast food chain says 395 of its stores around the country were affected. The data breach happened between August and September.
Dairy Queen says it worked with law enforcement authorities and credit card companies to investigate the breach. It says there's no evidence Social Security numbers, personal identification numbers or email addresses were accessed. The Edina, Minnesota-based company is offering customers free identity repair services.
