In the short term, low intensity large scale "offensive" action is probably the course to take with most potential return. Just poke with as many Russian server/service as possible. Since your country has a high risk of being (unfortunately) under Russian control soon, take some minimal precautions to cover your traces. This is basically the same principle as international sanctions. Try to make everything harder for Russia and (unfortunately) for Russian people. Playing people's opinion against their leader. You can do the same in Belarus that saw civil unrest recently, mobilizing Russian soldiers.
