SONIC Drive-In has acknowledged that some of its payment systems may have been breached after unusual activity was reported on credit cards used at SONIC locations.
SONIC has over 3,500 locations across the country, including four in Connecticut.
The company is working with law enforcement to determine the scope of the issue. A company spokesman did not say how many locations may have been affected and said the investigation was only in its beginning stages.
“Our credit card processor informed us last week of unusual activity regarding credit cards used at SONIC,” the company wrote in a statement.
“The security of our guests’ information is very important to SONIC. We are working to understand the nature and scope of this issue, as we know how important this is to our guests. We immediately engaged third-party forensic experts and law enforcement when we heard from our processor. While law enforcement limits the information we can share, we will communicate additional information as we are able.”
Anyone who has recently visited a SONIC and used a card to pay should monitor their accounts carefully and report any discrepancies to their financial institution.
