West Sacramento-based Raley's said today that it recently discovered that a portion of its computer network systems may have been the target of a cyber attack.
The company said an investigation was "immediately initiated" to determine whether the attackers obtained customer credit card and debit card information.
"At this time, we have not confirmed any unauthorized access to payment card data, but our investigation remains ongoing," the Raley's notice said. "We have no reason to believe that debit PIN numbers could have been accessed.
"We do not collect Social Security or drivers' license numbers in association with payment card transactions."
Raley said it has taken steps to enhance security measures to protect customer data. The company said it is confident that customers can continue using their payment cards in stores.
The grocer recommended that customers do the following:
Check/monitor bank and credit card statements for evidence of unauthorized transactions.
Contact your bank or credit card company if you identify suspicious charges.
