Dairy Queen, the ice cream and fast-food chain, is the latest retailer to reveal a hack of its customer data. The company said hackers may have gained access to customer names, credit and debit card numbers and expiration dates at 395 stoores between August and October. Officials said they have fixed the malware problem and that there's no evidence Social Security numbers, card PIN numbers or email addresses were stolen. The company is offering customers free identity repair services. In the past year, other retailers such as Target, Home Depot and Michael's have been targeted by cyberattacks.
