Colonial Pipeline begins restart efforts after disruptive cyberattack in U.S.

Colonial Pipeline said on Wednesday it has begun to restart the largest U.S. pipeline network six days after a ransomware attack prompted it to shut the line, triggering fuel shortages and panic buying in the southeastern United States.

It will take several days for the fuel delivery supply chain to return to normal, Colonial said. 

Colonial halted 2.5 million barrels per day of shipments of gasoline, diesel and jet fuel last Friday after the most disruptive cyberattack ever on U.S. energy infrastructure.

No plans to pay ransom

Sources familiar with Colonial's response said the company does not plan to pay the ransom demanded by hackers who encrypted data on the pipeline, which stretches 8,850 kilometres from U.S. Gulf Coast oil refineries to consumers in Mid-Atlantic and southeast states.

The supply crunch sparked panic buying in the U.S. southeast, bringing long lines and high prices at gas stations ahead of the Memorial Day holiday weekend at the end of May, the traditional start of the peak summer driving season. Observers reported fist fights erupting over fuel supplies in North Carolina and other places.

Nearly 60 per cent of gas stations in metro Atlanta were without gasoline, tracking firm GasBuddy said. Its survey showed 65 per cent of stations in North Carolina and 43 per cent in Georgia and South Carolina without fuel. Virginia also reported high outages.

U.S. Transportation Secretary Pete Buttigieg said the administration is addressing fuel shortages and helping restore Colonial operations.

"Our top priority right now is getting the fuel to the communities that need it, and we will continue doing everything that we can to meet that goal in the coming days," he told reporters at the White House.

At a Citgo station in East Atlanta, Charles Williams, an Atlanta-based musician, filled his wife's Mini Cooper after seeing people with large jerry cans loading up.

"I wouldn't say I know they're hoarding, but I don't know if they're helping," the 66-year-old said. "If gas is getting sold out everywhere, yeah, it's time to start to worry."

Gas prices go up

Privately owned Colonial Pipeline opened portions of the line manually in Georgia, Maryland, New Jersey and the Carolinas. It also accepted two million barrels of fuel to begin efforts to "substantially" restore operations by week's end, the company has said.

The average national gasoline price rose to above $3 US a gallon, the highest since October 2014, according to the American Automobile Association.

Fuel industry representatives urged consumers to stop panic buying. They noted the country has plenty of gasoline supplies and said hoarding is creating shortages in areas not served by the pipeline.

"Retailers right now have sold several days worth of inventory within a few hours," said Rob Underwood, president of the Energy Marketers of America.

Four southeastern states — Florida, North Carolina, Virginia and Georgia — joined federal regulators in relaxing driver and fuel restrictions to speed deliveries of supplies. Georgia suspended sales tax on gasoline until Saturday.

The FBI has accused a shadowy criminal gang called DarkSide of the ransomware attack. The group, believed to be based in Russia or Eastern Europe, has not directly taken credit for the Colonial hack, but on Wednesday it claimed to have breached systems at three other companies, including an Illinois tech firm.

Russia's embassy in the United States rejected speculation that Moscow was behind the attack. On Monday, U.S. President Joe Biden said there was no evidence so far that Russia was responsible.

It was not known how much money the hackers are seeking.

Gulf Coast refiners that move fuel to market on the Colonial Pipeline have cut processing. Total SE trimmed gasoline production at its Port Arthur, Tex., refinery, and Citgo Petroleum pared back at its Lake Charles, La., plant.

Citgo said it was moving products from Lake Charles and "exploring alternate supply methods into other impacted markets." Marathon Petroleum said it was "making adjustments."

Several airlines have been transporting fuel by truck or fuelling planes at destinations rather than at East Coast origins. American Airlines said it would resume on Thursday non-stop service on two long-haul flights out its Charlotte, N.C., hub.

Delta Air Lines Chief Executive Ed Bastian said the airline has been told fuel supplies will be available "hopefully by the end of the week and as long as those predictions come true hopefully we'll be OK."
