The first thing it does is check the device language. If it matches the language ID of Kazakhstan, Uzbekistan, Azerbaijan, Belarus or Russia, the software leaves the system without any malicious action otherwise you are fucked.
This is somewhat funny, since I expect that like everywhere on the world, quite a lot of users from those countries will have their windoze in US English only.
So it's a rather stupid way to be "racist"
It has to be the primary language or any?
It has occurred to me that maybe if we install one of those languages would this malware leave us alone?
