Attack on U.S. Power Grid Could Cost $1 Trillion, Lloyd’s Says

A cyber attack on the U.S. power grid could cost more than $1 trillion because of property damage, higher death rates and crippled infrastructure, according to Lloyd’s of London.

“The scenario predicts a rise in mortality rates as health and safety systems fail; a decline in trade as ports shut down; disruption to water supplies as electric pumps fail and chaos to transport networks,” according to a report from the insurance market and Cambridge University.
