Lisa Madigan Opens Investigation Into Jimmy John's Data Breach
Illinois Attorney General Lisa Madigan on Thursday warned residents who made purchases with their credit or debit cards at Jimmy John's to immediately be on the lookout for unauthorized charges on their accounts.
“Identity theft is a serious threat to consumers," Madigan said. "It’s critical to start incorporating extra precautions in your daily routine to limit the damage done as a result of a data breach.
Madigan has opened an investigation into the security breach at 216 of the Champaign-based company's restaurants.
Jimmy John's said Wednesday that stores in 37 states, including Illinois, were affected by the breach that occurred between June 16 and Sept. 5.
It appears customers' credit and debit card data was compromised after someone stole log-in credentials from a point-of-sale vendor, and used the information to remotely access the systems at the individual stores, company officials said.
The security issue has been contained and the company said customers can continue using their credit and debit cards securely at Jimmy John’s stores. Third-party forensic experts have been brought in to assist with the investigation.
The restaurant chain is offering credit protection services to customers impacted by the breaks. Call 1-855-398-6442 for more information.
Madigan said Illinois residents also can call her office’s Identity Theft Hotline at 1-866-999-5630 for assistance.
