New class of attacks dubbed MadIoT (Manipulation of demand via IoT) could cause local power outages or large-scale blackouts. Attackers could enslave high-wattage IoT devices in a botnet to manipulate the demand side of the grid. The risks of these attacks only increase in the future as more manufacturers come out with smarts appliances with the ability to connect to the internet. Princeton University researchers: It would take 90,000 air conditioners and 18,000 electric water heaters to disrupt the power demand in a targeted geographical area.”]
