The same operation has been doing DDoS attacks at various Russia-opponent-related targets for quite a long time, this is not a new unknown organization. However, yes, there doesn't seem to be a reason to assert that it is ordered by the Russian state (specific attributions e.g. to a particular agency or individuals have been made for certain operations, but generally it takes a lot of time and is done only in restrospective), it could be just a loose group of activists scattered around the world and sharing just a chat channel, this attack is unsophisticated enough to not require any specific resources or cooperation.
