One alarming academic article by Dheeraj Gurugubelli and Dr Chris Foreman of Purdue University sets out how a targeted attack on smart meters could potentially result in the shutdown of the power grid, disabling energy delivery systems. (They argue that “the compromise of even a single smart meter through focused attack or reverse engineering potentially provides access to the AMI network as a whole. This, coupled with the extensive use of multiple wireless technologies and geographic dispersion, results in an attack surface of unprecedented scale.”
