DENVER - Shoppers potentially picking up a few items for their Thanksgiving feast may have found fraudulent charges on their bank accounts a few days after shopping at Safeway.
The grocery store chain confirmed Wednesday that workers found card skimmers at checkout lanes in three Colorado stores.
Safeway reported the skimmers at the Colfax and Garrison store in Lakewood, the store at 44th and Lowell in Denver, and the Main Street store in Conifer.
Workers found them in early November. A story published Wednesday on the online cyber security blog "Krebs on Security" first reported the problem.
The blog says stores in California also found skimmers.
Safeway spokesperson Kris Staaf says surveillance video in the stores pinpointed when the devices were installed, though she's not giving a specific date. She says the skimmers were on the card readers for "a few days." Workers found them during routine inspections.
Staaf says the company did not notify customers. She says banks are typically good at detecting fraud and alerting customers. Staaf says the company's internal security team felt by warning customers, the company could compromise the investigation and the search for the suspect or suspects..
Safeway has notified authorities and banks.
The company released a statement Wednesday saying in part:
"Like all responsible business owners, our store teams routinely inspect all point of sale devices and discovered the three skimmers during these inspections. When our store teams find evidence of criminal activity like this, we have been able to pinpoint with surveillance video when the devices were installed and how many transactions were processed. We immediately followed the proper protocol of contacting law enforcement and the banks that service the few cards that were used on those pin pads. Customers who have any concerns, should review their bank statements for fraudulent activity in November, or contact their cardholder or bank directly."
