WEST SACRAMENTO (CBS/AP) -- Raley's Supermarkets was advising customers who used their credit or debit cards at any of its stores to check their statements because its computer network may have been the target of a cyberattack.
Raley's said on Thursday it has launched an investigation, and has so far not found any unauthorized access to payment card data.
Nicole Townsend, a Raley's spokeswoman, told the Sacramento Bee on Thursday that a credit card company notified the chain of suspicious activity on May 30 but she did not elaborate.
West Sacramento-based Raley's has 128 stores in Northern California and northern Nevada that operate under the names Raley's, Bel Air Markets, Nob Hill Foods and Food Source. It also operates Aisle 1 Fuel Stations.
