Dairy Queen stores hit by 'Backoff' malware, payment card data stolen

The systems were accessed using account credentials from a third-party vendor, Dairy Queen said

Dairy Queen said Thursday the "Backoff" point-of-sale malware infected systems at 395 of its stores, stealing payment card data.

The company, which has 4,500 independently owned franchises in the U.S., said in a statement it believes the "malware has been contained." Most of the stores, including one Orange Julius location, were affected for between three weeks to a month starting in early August, according to a list.

"We deeply regret any inconvenience this incident may cause," wrote CEO and President John Gainor.

The company is the latest one to disclose a data breach due to malicious software. Home Depot and Target disclosed large data breaches that compromised card data. Other companies affected were Neiman Marcus, Michaels, P.F. Chang's China Bistro and Sally Beauty.

Dairy Queen said its investigation showed that a third-party vendor's account credentials were used to access the systems at the affected locations. The same style of attack method yielded access to Target's systems. The vendor was not identified.

The stolen information comprised customer names, payment card numbers and card expiration dates. No customer information, such as Social Security numbers, PINs or email addresses were stolen, it said.

The U.S. Department of Homeland Security and Secret Service warned in August that upwards of 1,000 businesses may be infected by malware such as Backoff on their point-of-sale devices.

Backoff, which first appeared around October 2013, collects payment card data from a computer's RAM where it briefly sits unencrypted after a card is swiped.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
