Module advanced options (payload/windows/vncinject/reverse_tcp_rc4_dns):
Name Current Setting Required Description
---- --------------- -------- -----------
DisableSessionTracking false no Disables the VNC payload from following the active session as users log in an out of the input desktop
EnableStageEncoding false no Encode the second stage payload
