A pizza chain targeted in a credit card hacking scheme says its former law firm has a conflict of interest in the case because it’s representing the son of a Russian lawmaker charged with hacking into businesses across the U.S. Zpizza’s president told a federal judge Tuesday that the company shared confidential information with the Fox Rothschild firm that could benefit Roman Seleznev, saying the firm’s failure to reveal a possible conflict is “reprehensible.” The firm says it doesn’t believe there’s a conflict, because it no longer represents Zpizza and has barred communication between the attorneys representing Seleznev and the attorney that represented the restaurants.
