Do we know this or is this just a guess?

The infamous 1988 Morris worm was also thought to be something
similarly sinister for a short while until Bob Morris, Jr et al owned
up to it just being an experiment by a couple of students gone out of
control.

Back around 1986 I accidentally brought down at least half the net by
submitting a new hosts file (for Boston Univ) with an entry that
tickled a bug in the hosts.txt->/etc/hosts code which everyone ran at
midnight (whatever) causing a loop which filled /tmp (this would be
unix hosts but by count they were by far most of the connected
servers) and back then a full /tmp crashed unix and it often didn't
come back up until a human intervened.

Ok I doubt this was an accident, tho its scale could've been an
accident, a prank gone wild.

Anyhow what do we *know*?

That the effect was large doesn't necessarily imply that it required a
lot of resources.

We live in a world rife with asymmetric warfare. A few boxcutters and
3,000+ people dead.

Same question. Would Dyn et al publicize ransom demands at this point?

And even if not how do we rule out a prank or similar?

Is there something specific about this attack which required
significant resources? How significant?

Well, barring further details one can go anywhere with a few
suppositions.
