U.S. Working With Colonial Pipeline to Restore Operations After Cyber Attack The White House was working closely with top U.S. fuel pipeline operator Colonial Pipeline on Sunday to help it recover from a ransomware attack that forced the company to shut a critical fuel network supplying populous eastern states. The attack is one of the most disruptive digital ransom schemes reported and has prompted calls from American lawmakers to strengthen protections for critical U.S. energy infrastructure from hacking attacks. Commerce Secretary Gina Raimondo said the pipeline fix was a top priority for the Biden administration and Washington was working to avoid more severe fuel supply disruptions by helping Colonial restart as quickly as possible its more than 5,500-mile (8,850 km) pipeline network from Texas to New Jersey.
