Two German researchers have exploited security holes in a smart meter service to alter energy consumption rates, expose privacy flaws and determine what movies consumers had watched.
Dario Carluccio and Stephan Brinkhaus demonstrated the flaws with German energy company Discovergy at the Chaos Computing Congress in Berlin.
The researchers, also customers, learnt that energy consumption data was sent unencrypted because SSL was malfunctioning.
They intercepted and manipulated the data using Fritzbox! and WireShark and returned to the company a negative energy consumption rate of -106610 kWh.
Similar flaws also allowed Carluccio and Brinkhaus to demonstrate that a customer’s entire power consumption history was stored by Discovergy.
