Grocery wholesaler URM Stores, which processes payments for several grocery stores in the Pacific Northwest, recently announced that it had been "advised by law enforcement officials and a financial institution" that it may have been the target of a cyber attack against its payment processing system (h/t The Spokesman-Review).

A third party computer security firm uncovered signs of an attack, and the company says it's cooperating with law enforcement and implementing additional security measures.

"Until these measures are in place, you should consider paying with cash or check," URM CEO Ray Sprinkle wrote in a statement [PDF]. "Some stores may be able to process your card through a dial-up connection that is not affected by the attack. This process takes a few more minutes at the checkout stand and we ask for your patience."

The Spokesman-Review reports that affected stores include Yoke's Fresh Markets and Rosauers. "This is a ridiculously horrible time for this to happen," Yoke's CEO John Bole told the newspaper, noting that the time right before Thanksgiving is one of the busiest times of the year.

A dedicated call center has been set up to answer customers' questions at (877) 237-7408.
