Dynamic Port Forwarding

Dynamic port forwarding uses SSH to create a SOCKS proxy, allowing traffic to be routed through a tunnel to access external resources.

SSH

ssh -N -D <ssh_client_ip>:<ssh_client_port> <ssh_server_username>@<ssh_server_ip>

This creates a SOCKS proxy on specified port , routing traffic through the pivot machine interface.

To use it with proxychains, add to /etc/proxychains4.conf:

/etc/proxychains4.conf

socks5 <ip> <port>

Remote dynamic forwarding

The SSH server is the attacker local machine.

ssh -N -R <local_port> <ssh_server_username>@<ssh_server_ip>
