'Unusual activity' reported on credit cards used at Sonic locations
Sonic has acknowledged a security breach affecting an unknown number of its stores' payment systems.
Sonic says there's been some “unusual activity” on credit cards used at some of its restaurants.
There are five locations in the Pittsburgh area, among them at the Pittsburgh Mills mall complex in Frazer and on Route 30 in Hempfield.
The Oklahoma City-based fast food chain said in a statement that its credit card processor told them about the incident last week and that it's now “working to understand the nature and scope of this issue.”
It did not disclose how many credit cards were potentially involved in the incident or when the incident took place.
There are more than 3,500 Sonic restaurants in 44 states, according to the company's website.
Sonic said that it is working with third-party forensic experts and law enforcement officials on the incident.
The potential breach at Sonic was initially reported by Krebs on Security , which said the first hints of a breach at Sonic came last week when financial institutions noticed a recent pattern of fraudulent transactions on cards that had all previously been used at Sonic.
“The ongoing breach may have led to a fire sale on millions of stolen credit and debit card accounts that are now being peddled in shadowy underground cybercrime stores,” KrebsOnSecurity reported.
Sonic is not the first restaurant operator to deal with such issues.
Last year, Wendy's announced that hackers were able to steal customers' credit and debit card information at more than 1,000 of its U.S. locations.
Wendy's said at the time that the hackers were able to obtain card numbers, names, expiration dates and codes on the card.
Some customers' cards were used to make fraudulent purchases at other stores.
