p3nt4/invoke-socksproxySocks proxy, and reverse socks server using powershell.
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 to verify it:
openssl x509 -in cert.pem -noout -sha1 -fingerprint | cut -d "=" -f 2 | tr -d ":"
# Start the handler
python3 ReverseSocksProxyHandler.py 443 1080 ./cert.pem ./private.key
# On the local host:
Import-Module .\Invoke-SocksProxy.psm1
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost 192.168.49.130
# Go through the system proxy:
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost 192.168.49.130 -useSystemProxy
# Validate certificate
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost 192.168.49.130 -certFingerprint '93061FDB30D69A435ACF96430744C5CC5473D44E'
# Give up after a number of failed connections to the handler:
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost 192.168.49.130 -maxRetries 10
