# 1080 - Pentesting Socks

{{#include ../banners/hacktricks-training.md}}

## Basic Information

**SOCKS** is a protocol used for transferring data between a client and server through a proxy. The fifth version, **SOCKS5**, adds an optional authentication feature, allowing only authorized users to access the server. It primarily handles the proxying of TCP connections and the forwarding of UDP packets, operating at the session layer (Layer 5) of the OSI model.

**Default Port:** 1080

## Enumeration

### Authentication Check

```bash
nmap -p 1080 <ip> --script socks-auth-info
```

### Brute Force

#### Basic usage

```bash
nmap --script socks-brute -p 1080 <ip>
```

#### Advanced usage

```bash
nmap  --script socks-brute --script-args userdb=users.txt,passdb=rockyou.txt,unpwdb.timelimit=30m -p 1080 <ip>
```

#### Output

```
PORT     STATE SERVICE
1080/tcp open  socks

```

## 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
```
