U.S. motorists are expected to see a shortage of fuel and an increase in prices after a cyber-attack shut down the country’s largest pipeline. FSN reports that four days after the attack it’s still not clear when the pipeline, that carries almost half the east coast’s fuel supply, will be operating again. U.S. gasoline prices at the pump jumped 6 cents per gallon in the latest week, said the Automobile Association, and could soon be headed for the highest level since 2014 due to the supply disruption caused by a cyberattack on the country’s biggest fuel pipeline system.
