Dairy Queen Confirms Data Breach in 395 Stores
International Dairy Queen has confirmed a data breach did take place in 395 locations and may have affected nearly 600,000 debit and credit cards.
After an investigation that began in August, the company found that Backoff malware, used in so many recent cyber attacks, affected the payment systems in these locations. Customer names, debit card and credit card numbers and their expiration dates were compromised.
“We have no evidence that other customer personal information, such as Social Security numbers, PINs or email addresses, were compromised as a result of this malware infection,” John Gainor, the President and CEO, said in a statement.
Dairy Queen is owned by Berkshire Hathaway, and has 4,500 stores throughout the United States.
The locations of the stores are listed here.
The company is offering free identity repair services for one year to customers in the U.S. who used their payment card at one of the impacted locations during the relevant time period.
The Department of Homeland Security issued an advisory in August, stating more than 1,000 businesses were impacted by the “Backoff” malware used in the Target breach. Dairy Queen becomes the latest in a long line of retailers hacked within the last year, including Target, Neiman Marcus, Michaels, P.F. Chang’s, Jimmy John’s, UPS Stores, Sally Beauty, Home Depot and Supervalu and Albertsons grocery stores.
