This is a major story: a probably Russian cybercrime group called DarkSide shut down the Colonial Pipeline in a ransomware attack. The pipeline supplies much of the East Coast. This is the new and improved ransomware attack: the hackers stole nearly 100 gig of data, and are threatening to publish it. The White House has declared a state of emergency and has created a task force to deal with the problem, but it’s unclear what they can do. This is bad; our supply chains are so tightly coupled that this kind of thing can have disproportionate effects.

EDITED TO ADD (5/12): It seems that the billing system was attacked, and not the physical pipeline itself.
