DQ is hacked

Dairy Queen confirmed yesterday that 395 of the chain’s 4,500 system were infiltrated by the so-called Backoff malware program, raising the possibility some guests’ payment card information was stolen.

The vulnerable data was limited to the names, numbers and expiration dates of the cards, DQ said. Patrons’ social security numbers and e-mail addresses were not exposed during the breach.

One unit of Orange Julius, the chain’s smaller sister brand, was also infiltrated.

The franchisor said the breach was traced to the unauthorized use of a vendor’s means of entering data systems at selected units.
