Largest U.S. pipeline shuts down operations after ransomware attack

Colonial Pipeline, the largest fuel pipeline in the United States, has shut down operations after suffering what is reported to be a ransomware attack.

Colonial Pipeline transports refined petroleum products between refineries located in the Gulf Coast and markets throughout the southern and eastern United States. The company transports 2.5 million barrels per day through its 5,500 mile pipeline and provides 45% of all fuel consumed on the East Coast.

According to a report by CNBC, Colonial Pipeline suffered a ransomware attack yesterday that forced them to shut down their entire network to prevent the spread of the malware.

Today, Colonial Pipeline issued a statement confirming the attack and stated that they temporarily shut down their pipeline operations while responding to the attack.

"On May 7, the Colonial Pipeline Company learned it was the victim of a cybersecurity attack. In response, we proactively took certain systems offline to contain the threat, which has temporarily halted all pipeline operations, and affected some of our IT systems."

"Upon learning of the issue, a leading, third-party cybersecurity firm was engaged, and they have already launched an investigation into the nature and scope of this incident, which is ongoing," Colonial Pipeline said in a statement.

It is not known at this time what ransomware operation is behind the attack.
