KANSAS CITY, Mo. — One of the Midwest’s largest supermarket chains said Wednesday it has launched an investigation after noticing “unauthorized” activity involving its payment processing systems.
The company said in a statement that it is focusing its investigation on card transactions made at Hy-Vee gas station fuel pumps, drive-thru coffee shops and restaurants — including Market Grilles, Market Grille Express and Hy-vee owned and operated Wahlburgers.
Once the company noticed the activity, it said it worked with cybersecurity firms and notified federal law enforcement.
“We believe the actions we have taken have stopped the unauthorized activity on our payment processing systems,” the company said.
The company said the processing systems used at those locations are different than those used at grocery stores, drug stores and inside convenience stores.
“Based on our preliminary investigation, we believe payment card transactions that were swiped or inserted on these systems — which are utilized at our front-end checkout lanes, pharmacies, customer service counters, wine and spirits locations, floral departments, clinics and all other food service areas, as well as transactions processed through Aisles Online, are not involved,” the statement continued.
