DES MOINES, IOWA (KMHL) – Hy-Vee says it is in the early stages of investigating a data security incident involving their payment processing systems.

In a press release from the company, Hy-Vee says they have detected unauthorized activity in some of their payment systems.

The company says it is early in the investigation, but they immediately began investigating the issue with help from leading cybersecurity firms and reported it to law enforcement and the payment card networks.

“We believe the actions we have taken have stopped the unauthorized activity on our payment processing systems,” said Hy-Vee in the statement.

Hy-Vee says it is focusing the investigation on fuel pumps, drive-thru coffee shops and restaurants.

According to the company, those locations have different point-of-sale systems than those located at their grocery stores, drugstores and inside the convenience stores, which utilize a point-to-point encryption technology for processing payment card transactions.

“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 & spirits locations, floral departments, clinics and all other food service areas, as well as transactions processed through Aisles Online, are not involved,” said Hy-Vee.

The company says they’ll provide more details as they are known.
