most should be recovered. however no guarantees on all mods as the zip dump the attackers dropped cannot be confirmed to contain all the addons, or to contain safe versions of them. there's also a file count discrepancy between what they dumped and what was deleted off the cdn, which may mean some addons are gone.
to further clarify, the cdn was completely erased and the "zip dump" was uploaded by the attacker(s) in its place.
the zip is encrypted but apparently has the contents of the cdn in it prior to deletion (the file names weren't encrypted so are viewable).
it's either:
- an attempt at a joke, i.e. a "we can see the data but can't ever get it back" deal.
- leverage for some form of ransom or demand, although to my knowledge no ransom or demand has been received to this date. we wouldn't respond any way.
the file count discrepancy is not between the now-deleted cdn and the dump, the file count discrepancy is between
what we actually have left over on the glass server and the dump.
the now-deleted cdn is exactly that - deleted - there is nothing to compare it with any more except that encrypted dump file, and as far as i'm aware it is
literally just the entirety of the cdn but encrypted. we will never know if they actually made modifications to the contents because the contents are encrypted, and even if we had the password it would still be considered an untrustworthy source.
regardless, we're confident that in time all add-ons can be restored as the ones that are missing can easily be found elsewhere. what might be gone forever are all the add-on pages' screenshots since they were also stored on the cdn and it is unlikely anyone would have saved those specifically.
