Some parts of the country still face gas shortages related to the Colonial Pipeline ransomware attack, and the incident has drawn attention to the growing threat cyberattacks pose in the U.S. and around the world. We discuss the increasing threat and what to do about it.

The operator of the nation’s largest gasoline pipeline — hit on May 7 by a ransomware attack — announced Saturday that it has resumed “normal operations,” delivering fuel to its markets, including a large swath of the East Coast.

Gas shortages at the pumps have spread from the South, all but emptying stations in Washington, D.C., following a ransomware cyberattack that forced a shutdown of the nation’s largest gasoline pipeline. Though the pipeline operator paid a ransom, restoring service was taking time.

There is no gasoline shortage, according to government officials and energy analysts. But there is a problem getting the fuel from refineries on the Gulf Coast to the states that need it, and officials are scrambling to find alternate routes to deliver that fuel.

A cyberattack on a critical U.S. pipeline is sending ripple effects across the economy, highlighting cybersecurity vulnerabilities in the nation’s aging energy infrastructure.

As the shutdown of a major fuel pipeline entered into its fifth day, efforts are under way to stave off potential fuel shortages, though no widespread disruptions were evident.

The cyberextortion attempt that has forced the shutdown of a vital U.S. pipeline was carried out by a criminal gang known as DarkSide that cultivates a Robin Hood image of stealing from corporations and giving a cut to charity, a person close to the investigation said Sunday.
