Modus operandi: The Gas Lass parks her car in front of a gasoline station off the turnpike. It's late. There's no one around except a sleepy attendant at the register inside. The Gas Lass attaches a skimmer over the credit card reader at the pump. It's a special skimmer: It emits a Bluetooth signal to a laptop close by, says Noonan. The Gas Lass pays, heads off to the motel next door and sets up her laptop to receive the data from the compromised pump over the next several days.
Known whereabouts: The Gas Lass installs skimmers over ATMs, parking meters, vending machines and any other places with unmanned credit card readers.
