German security researchers Dario Carluccio and Stephan Brinkhaus recently demonstrated security flaws in German energy company Discovergy's smart meters that could allow attackers to change consumption information and access private data.
"The researchers, also customers, learnt that energy consumption data was sent unencrypted because SSL was malfunctioning," writes SC Magazine's Darren Pauli. "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," Pauli writes.
