Jimmy John’s data breach affects Marquette Township store

MARQUETTE TOWNSHIP — A national sandwich shop chain has experienced a data breach, and its store in Marquette Township has been affected.

Officials with Jimmy John’s say they believe login credentials were stolen in late July, allowing the thief to access cash registers remotely. Credit card numbers, expiration dates, names and other data were stolen.

Jimmy John’s says more than 200 stores nationwide have been affected, and their store on US-41 in Marquette Township is one of them. Customers that had a credit or debit card swiped at the store between July 1st and August 8th may be at risk.

It’s unknown how many customers have been affected. Jimmy John’s is asking customers that think they’ve been affected to contact the company at the corporate level, not the individual stores.
