This rule detects suspicious command-line activity indicative of a Remcos RAT loader attempting to establish persistence by copying or moving an executable (.exe) file into the AppData\Roaming directory. It specifically looks for 'cmd.exe' or 'powershell.exe' executing commands that contain both 'AppData\Roaming' or '%APPDATA%' and file manipulation commands ('copy', 'move', 'xcopy', 'REM') along with an '.exe' file extension.
