How do we know? for realz?
It's probably not Russia. Those guys seem totally legit. More likely some kids screwing in a basement. Rather kids screws around in a basement with their cell phones, and skateboards, and huluhoops, and their Nutflix, and their warez. All hacking is just some kids, you guys! Didn't you hear the goodly new orange guy? You can trust THAT knowledge. 4shore! *eggplant* *smilie face* *dog poop*
Ukraine has something even more to fear
The pro-democracy, anti-corruption groups in Ukraine got very little support from Europe and something from the USA, but now that Trump has an anti-Ukraine, pro-Russia team, Ukraine is probably looking at a very bleak future.

The whole country is just a pie for oligarchs, mobsters, extreme nationalists and possibly the "National Endowment for Democracy", what are you on about? I you expect DEMOCRACY! to spring up like that, especially after ultra-right-wingers were glorified in the "western free press" (complete with explained-away iconography) and are in control of security services, I have got a bridge to sell you.
They just got visa free travel for Europe as a show of solidarity, that's gotta count for something right?
> anti-Ukraine, pro-Russia team
What are you smoking during the day, then? How about "not interested in stirring up trouble in the ex-Soviet zone for the beautiful eyes of neocons".
"The West" (more like, the Blob) better normalize relationships, and then work from there. The unreal Freedom Fantasms of the up-militarized-by-NATO European supine and "self-interest-free" decision makers is especially disheartening.
So many suspects...
There are millions of people in Ukraine who are VERY angry with the banks in the latest scandal, in which millions of Ukrainians lost their life savings because the banks essentially just refused to pay out any of the accounts.
Poroshenko - aka Willy Wonka - has been a huge disappointment. He does done so little about the endemic corruption that even Saakashvili quit. Note, Saakashvili is wanted by Georgia on corruption charges. Not one banker has been investigated, and not one Hrivna has been returned.
So I suspect this is an internal Ukrainian activity, since there are a lot of very skilled citizens who have either lost lots of money to the banks, or their families have.
