Yeah, there’s a net of volunteers that are helping them at the moment, including helping them move towards Europe or settle in in Russia (surprisingly, some prefer to do it, especially if they have relatives somewhere, although it’s obviously a minority by far).
The scariest thing is the “filtration” that happens when they cross the border the first time — because we don’t really know what happens with those who fail it. Some were found in Russian prisons, I believe, but there are certainly Nazi vibes about that whole procedure and I’d fear for the worst.
