EDINA, MINN.—Dairy Queen has become the latest retailer to announce a data breach affecting consumer credit and debit cards.
The company said that 395 of its 4,500 locations, along with one Orange Julius location, were infected with the Backoff malware in which a third-party vendor’s compromised account credentials were used to access systems at some locations. The company said time periods during which the Backoff malware was present on the relevant systems vary by location, and it has published a list of impacted locations, as well as the relevant time periods, at www.dq.com/datasecurityincident/.
