I'm pretty sure Russian hackers target former USSR countries. Estonia and Ukraine come to mind, but I would imagine all of the Baltic states, Georgia, and Moldova would be ok as well.
There have been a ton of attacks originating from Russia against Ukraine and Estonia very publicly. Read Sandworm for a deep dive. Just because some hackers are lazy and use a Cyrillic keyboard as a lazy man's geofencing does not mean these countries are off limits.
