re: Can someone in the know explain RE: pipeline "hack"?

Like the rest of industry, pipelines have been automated and rely on software systems to safely operate. The automation performs basic operations like opening/closing valves, running pumps, scheduling deliveries and various other vital processes for operating a pipe. My understanding is it was a ransomware hack where the hackers shut down their internal systems in exchange for a large $ payout. Last update was they have "resolved" the issue and the pipe should be up and running by close of week.
