The thing is - I do not trust those reports at this time, as we have previous experience of such reports being falsified in the past in order to attain political ends. I would guess that this argument was already mentioned (and thus I appologise for probably over using it) but this looks like the pre-Iraq reporting or more recently US reporting on ISIS and Syrian rebel movement in general (where the reports regarding ISIS were changed in the military intel apparatus in order to suit the political needs at the time).

Regarding the reports, such as the 13 page one that you have linked, it does not have evidence regarding how they attributed the attacks. In fact the majority of that report is about how to prevent and deal with the attacks. Morever the report itself is poorly writen, as they mix the names of the actors with the software used (page 4 of the report) making me doubt the competence of it's authors and it's credibility.

I wonder if the purge of US intel comunity (especially the CIA) by Trump would change things, or if this patern of behaviour would contrinue, just with another vector.
