Colonial Pipeline attack underscores US energy’s vulnerability

The ransomware attack on Colonial Pipeline, the largest supplier of oil to the Northeast region of the United States, is underscoring just how vulnerable critical U.S. infrastructure is to cybercriminals in a way no previous attack has done, say U.S. officials and experts in the field.

The successful breach of Colonial Pipeline’s IT system forced the company to shut down 5,500 miles of pipelines to ensure hackers could not gain access to its operational technology.
