After a long analysis by me and my friends we've determined that after running their launcher and getting into a game some cmds pop-up and close in an instant. If you go to %appdata% -> roaming you'll notice some new files. a .bat file that seems to have a couple diff names "giy_SC.cmd", "calc.bat runs as calc.ps1". We've determined that it's a known rat called "ZGRat V1". Additionally it downloads "plugin3.mp4" that is an interesting file as well. Please find the proof below:
You can see the detailed analysis here as well as the replay monitor if you scroll on the webpage:
