This is my undergraduate assignment that I translated to English myself in the Data Security Systems course where I was only assigned to write an essay on “man in the middle” but I was also interested in practicing it using Arpspoof and Wireshark applications on Linux. Apart from myself, our group consists of my colleagues Yulianti Murprayana, I Made Dwi Angga Pratama, Muhammad Audy Bazly, and I Nyoman Arta Jaya. This task has never been published anywhere and we as the author and copyright holder license this assignment customized CC-BY-SA where anyone can share, copy, republish, and sell it on condition to state our name as the authors and notify that the original and open version available here. If only interested in the practice, just follow the video.

Chapter 1 Introduction

1.1 Background

Wireshark is a software for capturing packets passing on the network called packet sniffing. Sniffing itself means smell, used by dogs to catch traces. Wireshark is not shown to do hacking but as a traffic monitoring and hacking detector software, meaning that it is a software to monitor traffic conditions so that it can detect if there is a breach or something unusual on the network. However, Wireshark can also function as a hacking software.

Wireshark captures all passing packets, meaning that the username and password that is sent is captured. If you are connected to the network and you can find out what other hosts are connected, it is possible to kill the activities carried out by that host, namely by using ARP (Adress Resolution Protocol) poissoning and sniffing. In this assignment, we will try to capture a host’s username and password to various web addresses using a combination of scanning, ARP poissoning and sniffing methods.
