After completing a probe with cybersecurity firms and law enforcement, Chipotle  (CMG - Get Report) now believes that customers at stores across 48 states could have been affected by a hack on the company's payment systems between March 24 and April 19.

In some cases, the stolen data contained the customer's name in addition to their card number, expiration date and verification number.

"We removed the malware, and we continue to work with cybersecurity firms to evaluate ways to enhance our security measures. [We] are working with the payment card networks so that the banks that issue payment cards can be made aware and initiate heightened monitoring," the company said in a statement.
