Genesco, a specialty retailer of footwear, sports apparel and related accessories, has sued Visa USA for $13.3 million in fines. In 2010, the retailer suffered an intrusion in which unknown attackers attempted to steal payment card information from its networks. The attackers installed packet-sniffing malware on the company’s network in an apparent bid to grab unencrypted card data as it was being transmitted for approval to card-issuing banks. The retailer’s lawsuit is the first to challenge a credit card company on the issue of fines resulting from payment card data breaches.”]
