From a CSIS perspective, the activities of Russia are still a concern. Russia has a tremendous interest and focus in the Arctic. However, they are of less concern than, say, the activities of China and other hostile state actors at this time.
That's not to say they're not of concern. As you mentioned, since the invasion of Ukraine, there have been a number of international sanctions against Russia, which have limited their ability to be as effective in their intelligence collection activities as they were in the past.
