Dairy Queen is the latest fast-casual restaurant chain to announce its systems have been breached by hackers, joining the ranks of P.F. Chang’s, Target, Home Depot, and others. The company has been working with law enforcement, it says, to investigate an intrusion by the so-called “Backoff” malware that affected 395 of its 4,800 stores between August and September.
The company posted the list of affected stores, and while the blog KrebsOnSecurity reported back in August that finance types thought they’d seen signs of a DQ card breach, a spokesperson at the time would only say they were “still investigating.” The company now says it’s “confident that this malware has been contained,” and that there’s no evidence that Social Security numbers, card PINs, or email addresses were compromised — so, that just leaves names and credit- and debit-card info. The company is offering customers free “identity repair services.”
