Colonial pipeline that supplies fuel to nearly half of the east coast of the US had to shut down its entire network. This is said to be the handiwork of a professional cybercrime group called “DarkSide”, which deployed ransomware. This is one of the most devastating cyberattacks, in the recent past, as prolonged shut down of the line may cause the fuel prices to spike. While the investigation is underway, there is no given date when the pipeline will again start functioning.
