NEW YORK—Top U.S. fuel pipeline operator Colonial Pipeline has shut its entire network, the source of nearly half of the U.S. East Coast’s fuel supply, after a cyber attack that the company said was caused by ransomware.
The shutdown has raised fears of a price spike at the gas pumps ahead of peak demand summer driving season if it persists, and has drawn attention to how critical U.S. energy infrastructure is vulnerable to hackers.
