Colonial Pipeline transports gasoline, diesel, jet fuel and heating oil from refineries. The pipeline network extends from Texas to New Jersey.
The oil pipeline was hacked in May with a ransomware virus.
This led to a halt in the supply of gasoline and other fuels used on the populous east coast of the United States.
Only after that the company had paid $ 4.4 million – around 40 million kroner – in ransom, they could use the cable again.
The hacker group Darkside themselves have said that they are behind the attack. The group is described by Western security experts as a criminal network.
