Invoke-SocksProxy - Socks Proxy, And Reverse Socks Server Using Powershell


7.2 High

AI Score



Creates a local or “reverse” Socks proxy using powershell.

The local proxy is a simple Socks 4/5 proxy.

The reverse proxy creates a tcp tunnel by initiating outbond SSL connections that can go through the system’s proxy. The tunnel can then be used as a socks proxy on the remote host to pivot into the local host’s network.



Create a Socks 4/5 proxy on port 1080:

Import-Module .\Invoke-SocksProxy.psm1  
Invoke-SocksProxy -bindPort 1080  

Increase the maximum number of threads from 200 to 400

Import-Module .\Invoke-SocksProxy.psm1  
Invoke-SocksProxy -threads 400  


Create a “reverse” Socks 4/5 proxy on port 1080 of a remote host:

# On the remote host:   
# Generate a private key and self signed cert  
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout private.key -out cert.pem  
# Get the certificate [fingerprint](<> "fingerprint" ) to verify it:  
openssl x509 -in cert.pem -noout -sha1 -fingerprint | cut -d "=" -f 2 | tr -d ":"  
# Start the handler  
python 443 1080 ./cert.pem ./private.key  
# On the local host:  
Import-Module .\Invoke-SocksProxy.psm1  
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost   
# Go through the system proxy:  
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost -useSystemProxy  
# Validate certificate  
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost -certFingerprint '93061FDB30D69A435ACF96430744C5CC5473D44E'  
# Give up after a number of fail   ed connections to the handler:  
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost -maxRetries 10

  • This is only a subset of the Socks 4 and 5 protocols: It does not support authentication, It does not support UDP or bind requests.
  • When the Socks Proxy runs out of available threads, new connections cannot be established until a thread is freed.
  • New features will be implemented in the future. PR are welcome.


This project is intended for security researchers and penetration testers and should only be used with the approval of system owners.
