NEW YORK - Even ice cream isn't safe from hackers.
Fast-food and ice cream chain Dairy Queen said Thursday that hackers may have gained access to customer names, credit and debit card numbers and expiration dates at 395 stores between August and October. The company said it has fixed the problem, which stems from malware dubbed "Backoff."
"Based on our investigation, we are confident that this malware has been contained," said Dairy Queen CEO John Gainor in a statement.
International Dairy Queen has about 4,500 franchised stores in the U.S. It's also the parent of the Orange Julius chain, and one stand-alone Orange Julius store was breached. The company said a third-party vendor's account credentials were used to access the systems at affected stores.
Dairy Queen said there's no evidence Social Security numbers, card PIN numbers or email addresses were stolen.
The Edina, Minnesota-based company, which is owned by Warren Buffett's Berkshire Hathaway (BRK.A), is offering customers free identity repair services.
