MADISON, Wis. (WMTV) - The Caribou Coffee chain is reporting a data breach to its network, exposing some of its customers’ data.
Caribou said in a press release Friday that customers who visited its website between Aug. 28 and Dec. 3, 2018 may be vulnerable.
The Minnesota-based company said names as well as credit card information including card number, expiration date and card security code may have been accessed during that time.
While Caribou customers may have been affected, the company said customers of Bruegger’s Bagels, Einstein Bros. Bagels, Manhattan Bagel and Noah’s NY Bagels were not affected by the breach.
Cyber security firm Mandiant is currently investigating the data breach. Caribou reported unusual activity on its networks on Nov. 28. On Nov. 30 Mandiant reported it detected unauthorized access into Caribou’s sales system.
“Mandiant worked with us to contain the breach and ensure that the unauthorized access was stopped immediately,” according to Caribou’s press release. “At this time, we are confident that the breach has been contained.”
Caribou added that it is in contact with credit card companies in order to warn customers’ banks.
Caribou recommends customers review credit and debit card statements. If you have been affected, you are asked to report it to your credit or debit card companies.
