A hacker, alleged to be an arrested 20-year-old Omar Ramos-Lopez, a former Texas Auto Center employee who was laid off last month, used a web-based vehicle-immobilization system run by credit and repo companies to remotely brick about 100 vehicles sold by the center in what authorities believe was an act of revenge. The hacker set off the vehicles' horns and rendered the cars undriveable.
