Cyber Attack on Power Grid Could Cost $243B, Study Says

Lloyd’s, a specialist insurance market, partnered with the Centre for Risk Studies at the University of Cambridge to calculate the potential economic damage of cyber crime that targets the national power grid. Under one scenario, an attack -- orchestrated, the report suggests, by terrorists, “hacktivists” (like, say, Anonymous) or maybe “disgruntled insiders” -- that knocks out 50 of the almost 700 generators serving the northeastern U.S. and causes a blackout of around four days would lead to $243 billion in immediate and tangential economic loss.
