Wait hang on, that cliff hanger though

>"Multiple security experts quickly zeroed in on how investigators were able to retrieve the funds, which did not represent the total amount Colonial paid (~$4.4 million): The amount seized was roughly what a top DarkSide affiliate would have earned for scoring the initial malware infection that precipitated the ransomware incident."

I'm not quite sure what this implies? That the team who did the initial infection was in fact some sort of FBI undercover?

So undercover FBI successfully hacked colonial pipeline, ignited all this press coverage and attention, and quietly disappeared with the ransom amount? Am I interpreting that correctly?
