1080 - Pentesting Socks

Basic Information
SOCKS is an Internet protocol that exchanges network packets between a client and server through a proxy server. SOCKS5 optionally provides authentication,
so only authorized users may access a server.
Practically, a SOCKS server proxies TCP connections to an arbitrary IP address, and provides a means for UDP packets to be forwarded.
SOCKS performs at Layer 5 of the OSI model
Default Port: 1080
Enumeration
Authentication Check
nmap -p 1080 <ip> --script socks-auth-info
Brute Force
Basic usage
nmap --script socks-brute -p 1080 <ip>
Advanced usage
nmap  --script socks-brute --script-args userdb=users.txt,passdb=rockyou.txt,unpwdb.timelimit=30m -p 1080 <ip>
Output

Tunneling and Port Forwarding
Basic proxychains usage
Setup proxy chains to use socks proxy
nano /etc/proxychains4.conf
Edit the bottom and add your proxy
socks5 10.10.10.10 1080
With auth
socks5 10.10.10.10 1080 username password
