Colonial Pipeline, operator of the largest U.S. fuel pipeline, said Wednesday it is restarting operations after being shut down for five days due to a cyberattack.
The company shut down its entire operation Friday after its financial computer networks were infected by a Russia-tied hacker gang known as DarkSide, fearing that the hackers could spread to its industrial operations as well.
The shutdown led to widespread gasoline shortages and caused temporary price spikes. The U.S. saw the problem as serious enough to issue an emergency order that relaxed restrictions for drivers carrying fuel in affected states.
