Bloomberg reports that the owner of Cisero's in Park City, Utah is suing the restaurant's payment processor and bank over $82,692 in fines from card issuers related to an alleged (but not confirmed) security breach.

"Two independent forensic investigations found that the restaurant had unknowingly stored credit card numbers, but there was no clear evidence of any actual breach," according to "Despite the absence of confirmation of any breach that could account for customers’ fraudulent charges elsewhere, Visa ultimately fined U.S. Bank, the acquiring bank."

"At issue here is that the restauranteur’s claim that there was no evidence that they had been hacked, Visa didn’t prove that there had been a compromise of their system that resulted in fraud, and that although they had unknowingly stored over 8,000 card numbers, that number was below the contractual threshold to trigger fines," the article states.
