Mexican fast food chain Chipotle announced in April that its customer payment system had been breached, CNBC reported, and the company released locations affected by the nationwide data breach, including 22 in Connecticut.
In a statement on the company's website, Chipotle said it detected "unauthorized activity" on the system. Officials are focusing on credit card transactions that occurred from March 24, 2017, to April 18, 2017.
"The malware searched for track data (which sometimes has cardholder name in addition to card number, expiration date, and internal verification code) read from the magnetic stripe of a payment card as it was being routed through the point-of-sale device," the company said in a statement on its website.
Chipotle said that not all locations were involved and specific time frames vary by location.
The restaurant added that the breach has been stopped and additional security measures have been added, though the investigation is ongoing. Chipotle encouraged customers to monitor their card activity.
