Dairy Queen and Kmart security breached

Both Dairy Queen and Kmart are the latest stores to be plagued with computer security breaches. Dairy Queen said 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 e-mail addresses were accessed. The Edina, Minnesotabased company, is offering customers free identity repair services.

Retailer Sears Holdings Corp said the payment data system at its Kmart unit had been breached, and that certain debit and credit card numbers could have been compromised.

The data hacking at Kmart discount stores comes after a slew of data breaches at US companies over the last two years.
