Note

This undergraduate assignment in the Data Security System course is a scientific version of previous tutorial. Actually, we were only given the task of writing an essay on bruteforce, but I happened to try Backtrack Linux at that time and decided to pratice the bruteforce with Hydra. Apart from me, our group consisted of Yulianti Murprayana, Nyoman Arta Jaya, Muhammad Audy Bazly, and Dwi Angga Pratama.

If you just want to experiment, just follow the video.

Chapter 1 Introduction

1.1 Background

Bruteforce is a computer network breaching technique by trying all the words in the dictionary as a username and/or password to enter a network. From the word bruteforce itself means to force purely using force. For hackers, bruteforce is the last solution to breach computer networks. However, this technique is rarely used because it requires a long time, large dictionary files, high computer specs and other similar types. If the hacker’s human resources are sufficient, this technique is sure to work. Although this technique is commonly known and understood by its mechanism of action, few people know its application. In other words, many know the theory but never take this action. In this paper, an experiment will be conducted to perform bruteforce with Hydra software available on the Linux operating system. The experimental material is the Windows 7 operating system on the telnet service.
