Researchers say new attack could take down the European power grid
Power grid in Central Europe uses unencrypted radio signals to add and shed loads.
After observing a radio receiver on the streetlight poles throughout Berlin, they got to wondering: Would it be possible for someone with a central transmitter to control them en masse, and if so, could they create a city-wide light installation along the lines of Project Blinkenlights? The researchers, who presented their work last month at the 38th Chaos Communication Congress in Hamburg, Germany, wondered if they could control streetlights in Berlin to create a city-wide version, though they acknowledged it would likely be viewable only from high altitudes. With confidence that an attacker could send unauthorized Radio Ripple Control telegrams that instructed real electrical systems connected to the grid, the researchers got to wondering: What's the maximum amount of damage a malicious actor—most likely one working for a nation-state—could inflict?
