Kruger national retailer said on Friday that authorized users have violated some of its financial and health data.
The company stated that a “limited number” of customers and employees were affected by the violation. The company believes that less than 1% of its customers are affected.
The supermarket chain added that there was no access to credit or debit card information during the attack.
This is one of the many companies affected by using Accellion to violate secure third-party file transfers, Kruger said. Kruger said it no longer uses Accellion’s services.
Customers seeking additional information about violations can call the incident telephone number at 1 (855) 558-2999 between 6 a.m. 8:00 PM PDT (Monday through Friday) and 8:00 AM PDT (Saturday and Sunday).
Kroger is the parent company of several other regional supermarket chains, including Ralphs, Harris Teeter, Fry’s, King Soopers and Fred Meyer.
