A cyberattack has prompted a company that operates a major energy pipeline in the U.S. to shut down operations.
The Colonial Pipeline Company said in a statement it learned on Friday that it was the victim of a cybersecurity attack, and so “proactively took certain systems offline to contain the threat, which has temporarily halted all pipeline operations, and affected some of our IT systems.”
In an updated statement on Saturday afternoon it said it had “determined that this incident involves ransomware.”
In most ransomware attacks, criminal hackers seize data and demand a large payment to release it, although it’s unclear what was taken or whether any demands were made.
The breach appears to be an attack on the nation’s critical energy infrastructure.
The company describes its pipeline as “the largest refined products pipeline in the United States,” and says it transports more than 100 million gallons of fuel through a pipeline system spanning 5,500 miles between Texas and New Jersey.
