A popular gourmet sandwich restaurant chain may have dished out more than your favorite submarine sandwich recently. According to security journalist Brian Krebs, Jimmy John’s is investigating a possible breach involving customer credit card information.
Several major credit card institutions have reported a pattern of fraudulent activity on cards used at Jimmy John’s retail locations. The “card-present” fraud activity enables hackers to create duplicate stolen credit cards. Typically, this form of card fraud is carried out through payment terminals that have been compromised by malicious software.
A spokesperson for the Champaign, Ill.-based Jimmy John’s told Krebs Thursday that “Jimmy John’s is currently working with the proper authorities and investigating the situation. We will provide an update as soon as we have additional information.”
Though Jimmy John’s has nearly 2,000 locations in the U.S., 98 percent are independently operated and may not function on the same information technology. The suggested franchise point-of-sale (POS) system, Signature Systems Inc., declined to comment to Krebs inquiries.
