A federal judge has thrown out all but one civil lawsuit in the Hannaford data breach case. In his ruling, U.S. District Judge D. Brock Hornby said Tuesday that consumers whose payment data are stolen can recover claims only if a merchant’s negligence caused a direct loss to the consumer’s account; plaintiffs who cited inconvenience or distress because of the breach could not. Of 4.2 million credentials exposed, no more than 1,800 were ever used for unauthorized purchases, according to Hannaford. — CAM
