- '%HOMEPATH%\CaIocokM\GocwIYEU.exe'
Executes the following:
- '<SYSTEM32>\cscript.exe' <LS_APPDATA>\Temp/file.vbs
- '<SYSTEM32>\reg.exe' /pid=0xbd0 /log
- '<SYSTEM32>\reg.exe' add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /d 0 /t REG_DWORD /f
- '<SYSTEM32>\reg.exe' add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /f /v HideFileExt /t REG_DWORD /d 1
