Supermarket chain Hy-Vee has revealed that the credit card payment information of some of its customers has been exposed in a recent data breach.
The Iowa-based company, which has grocery stores dotted around southern Minnesota and the Twin Cities, says there was a "security incident" involving the payment processing systems at its fuel pumps, drive-thru coffee shops and restaurants.
The restaurants include its Market Grilles, Market Grille Express and Wahlburgers locations operating at Hy-Vee grocery stores.
Hy-Vee says it recently detected "unauthorized activity" on these payment systems, prompting it to bring in cybersecurity experts and notify federal law enforcement.
"We believe the actions we have taken have stopped the unauthorized activity on our payment processing systems," a company statement said.
"Because the investigation is in its earliest stages, we do not have any additional details to provide at this time," it added. "We will provide notification to our customers as we get further clarity about the specific timeframes and locations that may have been involved."
These places have different payment processing systems than Hy-Vee's grocery, liquor and drug stores, which have not been impacted by the breach.
Nonetheless anyone who has used Hy-Vee's gas stations, coffee shops and restaurants are advised to keep an eye on their credit card statements for any unusual activity.
