Null Sessions

Checking if Null Session is enabled on the network, can be very useful on a Domain Controller to enumerate users, groups, password policy etc

#~ cme smb 10.10.10.161 -u '' -p ''
#~ cme smb 10.10.10.161 --pass-pol
#~ cme smb 10.10.10.161 --users
#~ cme smb 10.10.10.161 --groups

You can also reproduce this behavior with smbclient or rpcclient

smbclient -N -U "" -L \\10.10.10.161

rpcclient -N -U "" -L \\10.10.10.161
rpcclient $> enumdomusers
user:[bonclay] rid:[0x46e]
user:[zoro] rid:[0x46f]

Forest or Monteverde machines are good examples to test null session authentication with CrackMapExec
