ARP Spoofing with Kali Linux: An Introduction to Man-in-the-Middle Attacks

====================================================================================

In this tutorial series on penetration testing and information gathering using Kali Linux, we will delve into various techniques for compromising network security. In the first part of our three-part series, we'll explore one fundamental attack method – ARP Spoofing.

What is ARP Spoofing?

-----------------

ARP (Address Resolution Protocol) spoofing is a type of man-in-the-middle (MITM) attack where an attacker intercepts and manipulates Address Resolution Protocol packets between two or more devices on the same network. By doing so, the attacker can impersonate legitimate devices to eavesdrop on traffic or even inject malicious data.

Setting up Kali Linux for ARP Spoofing

-----------------------------

Before we dive into the technical aspects of this attack, let's set up our environment:

1. Install VirtualBox and download the latest version of Kali Linux ISO from its official website.

2. Create two virtual machines: one running Metasploitable 2 (Target 1) with IP address `10.0.2.100` and another running XP (Target 2) with IP address `192.168.101.102`.

3. Connect both virtual machines to the same network interface on your host machine.

Step-by-Step ARP Spoofing Tutorial

------------------------------

### Step 1: Installing Ettercap

Firstly, we need to install the required tools onto our Kali Linux system:

```bash

sudo apt-get update -y && sudo apt-get upgrade -y --force-yes && echo 'deb http://k4.ubuntu.com/~nsp/ k3v2 main' | tee /etc/apt/sources.list.d/nmap-k3v2bak.ppa.conf; curl -O https://launchpad.net/~nmap/magicwand/trunk/+archive/ppa-release.gpg > ~/magicwand.key && sudo apt-key add ~/magicwand.key && rm -rf ~/magicwand.key&&sudo apt-get update -y && sudo apt-get install libssl-dev python2.7-libffi6 libgcrypt11 libglib2-30 libnetfilter-queue1 netfilter-pmasq ettercap-textual --force-yes

```

### Step 2: Configuring Ettercap

After installing the necessary tools, let's configure our environment:

```bash

sudo service network restart && sudo apt-get install arpspoof -y && echo 'nameserver 192.168.101.1' > /etc/resolv.conf; echo 'interface eth0' >> ~/.etterc/ etterrc ; echo 'congestion timeout 10000'>>~/.etterc/etcetera/capture/packets/tap0.prerun0';echo -n 'arpspoof --spoof -- poisoning --arp --local-only tap0;sleep 2;' > ~/.getterpreruntargets && echo 'exit' >> ~.gettermux

```

### Step 3: Executing ARP Spoofing

Now that we have everything set up, let's execute the attack:

```bash

sudo apt-get install arpspoitype -y; sudo service network restart && arpspoitetype --help; arpspoif eth0 tap0 && ettercap -f ~/.etterpreruntargets -P /usr/local/bin/etter.cap

```

Verifying ARP Cache Poisoning

--------------------------

To verify whether our attack was successful, let's check the ARP cache on both target machines:

```bash

arp -n | grep 192.168.101.1 && arp -n | grep

```

-------

In conclusion, this tutorial has covered a basic introduction to man-in-the-middle (MITM) attacks using Kali Linux and Ettercap toolset for penetration testing purposes only.

Remember that all activities described above should be performed on your own network with proper permissions. Never attempt these techniques against unauthorised systems or networks without explicit permission from their owners.

In our next tutorial, we'll explore more advanced techniques such as SSLStrip to further compromise web applications and steal sensitive user data through man-in-the-middle attacks!
