i don't think this topic can move beyond speculation. this is probably about the best summary of the reality of things that you'll find:

Although the Russian military has been slow to embrace cyber for both structural and doctrinal reasons, the Kremlin has signaled that it intends to bolster the offensive as well as the defensive cyber capabilities of its armed forces. 

i might add that it has probably been slow to adopt cyber warfare for simple technical reasons, as well.

i know it's hard to drop the idea of the superior or at least comparable russian threat, but the reality is that it was always nonsense. they were stuck in the dark ages up to world war one, and only got out of it due to a lot of fdi from american capital. in world war two, they couldn't compete with the germans on technological terms; they just (eventually) overran them with sheer force, and, again, with a lot of help from the united states (lend-lease). during the war, the russians captured a substantial number of the best german scientists and kept them working on the space program for decades afterwards. but, they also carried out a lot of espionage. there was certainly not a lot of space for technology to flourish after the fall of communism; what you had, instead, was widespread theft and piracy of western technology, with little innovation in the region, itself. if the russians have cyberwarfare capabilities, they would have been built from scratch over the last ten years, and would necessarily be still playing catch-up. but, the russians have been playing catch-up the whole time...

i mean, you'll note that putin runs windows on his desktop, right?

i'm picking up on an idea that has been expanded upon by a number of writers. to be balanced, i'll cite both sutton and chomsky. they were always years - decades - behind us. this is the reality: the russians have been chasing the west since napoleon, at least.

there was a section in the oliver stone interview where oliver stone seems convinced that putin is hiding something. that's not exactly what i picked up. but, if you want to use that language, then what he's hiding is that there isn't a substantial russian cyberwarfare program - because they don't have the capability to construct one that is competitive with the real players: the united states, israel and china.

i didn't get a lot out of the series. but, it wasn't meant for me.
