Chipotle says hackers hit most restaurants in data breach
By Lisa Baertlein
Hackers used malware to steal customer payment data from most of Chipotle Mexican Grill Inc's (CMG.N) restaurants over a span of three weeks, the company said on Friday, adding to woes at the chain that has just started recovering from a string of food safety lapses in 2015.
Chipotle said it did not know how many payment cards or customers were affected by the breach that struck most of its roughly 2,250 restaurants for varying amounts of time between March 24 and April 18, spokesman Chris Arnold said via email.
Stolen data included account numbers and internal verification codes.
The malware has since been removed.
The information could be used to drain bank accounts, make "clone" credit cards, or to buy things on certain less-secure online sites, said Paul Stephens, director of policy and advocacy at the non-profit Privacy Rights Clearinghouse.
An investigation into the breach found the malware searched for track data from the magnetic stripe of payment cards.
Chipotle is not offering credit monitoring or notifying affected customers directly, as many other chains have in the past. A handful of Canadian restaurants were also hit.
"Credit monitoring is only designed to let you know when someone is opening a new credit account using your information. Credit monitoring does not alert you when a fraudulent charge is made on a payment card," Arnold said.
He also said that Chipotle could not alert customers directly as it did not collect their names and mailing addresses at the time of purchase.
The company said it had posted a notification on the Chipotle and Pizzeria Locale websites and issued a press release to make customers aware of the incident.
Linn Freedman, an attorney at Robinson & Cole LLP specializing in data breaches, said Chipotle was putting the burden on the consumer to discover possible fraudulent transactions by notifying them through the websites.
"I don't think you will get to all of the customers who might have been affected," she said.
Shares in Chipotle Mexican Grill ended marginally lower at $480.15 on Friday following the announcement.
