Ransoming Colonial basically put Darkside out of business. no one is going to hit them again

Their stuff may have been seized, but their business model has not to my knowledge been invalidated. Ransomware is not a capital-intensive business. A new generation of ransomware groups will quickly spring up to replace DarkSide.

Or, so they say... We really don't know enough to say anything here. It might just as well be that whoever controls the funds at Darkside pulled an exit scam.
