No.  I suppose at some level I am implying that it was possible that it could 
have been, but I seriously doubt that it was.  What I am saying is that there 
are so many ways these systems can fail that it is easy to provide an alternate 
public story that most of the people directly involved with the systems would 
not be able to discern.  Obviously, actual participants of such stories would 
be aware.

I can see how this could be read as a spiraling conversation about cover-ups 
and conspiracies (I thought it might when I wrote the first comment), but that 
was not my intent and I'm not likely to pursue such a pointless back-and-forth. 
 In the vast majority of cases I am of the opinion that conspiracy theories are 
absolute bunkum.  However, there are some marginal situations where motivation 
and opportunity do lend themselves to obfuscation.  In this case, it would not 
destroy my world-view if I were to find out that the Brazilian grid operators 
turned out to be unable to determine whether their system was hacked and 
whether the sub-standard materials were to blame as opposed to someone jacking 
with their transmission equipment causing some of the sub-standard materials to 
fail - and further that related authorities might be tempted to point to said 
sub-standard materials with a "nothing to see here" declaration.

The grid is making forward strides - which I couldn't be happier about - but as 
you say NERC CIP will look limited compared to more evolved standards.  Major 
parts of the grid are getting much more resource than smaller parts, as is only 
expected.  But the grid consists of an enormous amount of individual players 
and the vast majority of those are severely challenged.  The scope of the 
effort to address issues in the grid alone is out of scale with the resources 
available to do so.

Moreover, the grid is only a (very large) small part of deployed control 
systems.  There are an extremely large number of control systems deployed in an 
enormous range of applications throughout the infrastructure, and beyond some 
parts of the grid virtually none of them are being addressed at all.  These 
systems are in both 'trivial' and non-trivial applications.

You disagree that we need to regularize our approach, or that it is necessary 
to do so to make headway?

Perhaps I overstated, let me try again:

We need to regularize our approach to CIP cybersecurity or we are extremely 
unlikely to make adequate headway in an appropriate amount of time.

Lessons are being learned, those can be repeated and built upon.  However, 
compared to standard IT networks (which not even I would argue are secured to a 
highly satisfactory level), control system security is at best underdeveloped 
and underdelivered.
