can i open it in a VM to see what happens?


?
If you need to ask...
NO!Really, when analysing malware, if you don't know exactly what you're doing and that you're doing it safely, don't do it at all!

I did not want to ask.
I wanted to run in a VM under ubuntu on a newly formatted laptop without personal data. I wanted to analyze it, do some network captures and putting infected files on my VM. But I read "this RAT actually checks if virtualbox is installed and running, and exits if it is. So it tries to evade analysis That Way." and do not understand what this means.
As I can analyze it?
Any tool?
