NEW YORK - Top U.S. fuel pipeline operator Colonial Pipeline has shut its entire network after a cyberattack that industry sources said was caused by ransomware software.

Colonial's network supplies fuel from U.S refiners on the Gulf Coast to the populous eastern and southern United States.

The company transports 2.5 million barrels per day of gasoline, diesel, jet fuel and other refined products through 8,850 kilometers (5,500 miles) of pipelines, and it transports 45% of the East Coast fuel supply.

The malicious software used in the attack was ransomware, two cybersecurity industry sources familiar with the matter said. Ransomware is a type of malware that is designed to lock down systems by encrypting data and demanding payment to regain access. The malware has grown in popularity over the last five years and is most often deployed by cyber-criminal groups.

The company shut down systems to contain the threat after learning of the attack on Friday, Colonial said in the statement. That action has temporarily halted operations and affected some of its IT systems, the company said.

Colonial has engaged a third-party cybersecurity firm to launch an investigation and has contacted law enforcement and other federal agencies, it said.

Colonial did not give further details or say for how long its pipelines would be shut.

"Cybersecurity vulnerabilities have become a systemic issue," said Algirde Pipikaite, cyber strategy lead at the World Economic Forum's Center for Cybersecurity.

"Unless cybersecurity measures are embedded in a technology's development phase, we are likely to see more frequent attacks on industrial systems like oil and gas pipelines or water treatment plants," Pipikaite added.

Reuters reported earlier Friday that Colonial had shut its main gasoline and distillate lines.

During Friday's trading session, Gulf Coast cash prices for gasoline and diesel edged lower. Both gasoline and diesel futures on the New York Mercantile Exchange rose more than crude prices during the day. Gasoline futures gained 0.6% to settle at $2.1269 a gallon, while diesel futures rose 1.1% to settle at $2.0106 a gallon.

"The fact that this attack compromised systems that control pipeline infrastructure indicates that either the attack was extremely sophisticated, or the systems were not well secured," said Mike Chapple, a professor at the University of Notre Dame's Mendoza College of Business and a former computer scientist with the U.S. National Security Agency.

Longer-term prices will depend on the amount of time that the lines are shut. If barrels are not able to make it onto the lines, Gulf Coast prices could weaken further, while benchmark prices in New York Harbor could rise, one market participant said. Rising benchmark prices are typically followed by price hikes at the pump.

Colonial shut down its gasoline and distillate lines during Hurricane Harvey, which hit the Gulf Coast in 2017. That contributed to tight supplies and gasoline price rises in the United States after the hurricane forced many Gulf refineries to shut down.
