Excellent Knowledge about Ethical Hacking using Python.

It is a usual practice amongst ethical hackers to write useful scripts and automate any structured process, varying from small network scans to wide area network packet sniffing. In recent years, Python has become the language of choice for such tasks, and there are useful purposes for this. In this article on ethical hacking using Python, we will discuss the reasons that make these two such a brilliant couple.

Here is the list of topics we shall be going over:

 What is Ethical Hacking?

The word hacking goes a long way back. To be specific, it all started at the Railroad Club of MIT, where it first coined both the term ‘hacking’ and ‘hacker’. It’s been nearly 50 years now, and hacking has evolved into a discipline in the present day and age. With the increase in experience regarding data protection and data privacy, hacking has been considered as an illegal activity today. If caught, there’s a real chance that you will be prosecuted for quite a wonderful time depending on the extent of harm caused.

Nonetheless to shield themselves from hackers of all sorts, the profession of Ethical Hackers has become a regular practice amongst organizations. Ethical hackers have the responsibility of finding and fixing security flaws for a particular organization before black hat hackers find them.

What is Python?

Python is a scripting language with general-purpose that has earned immense fame amongst professionals and beginners for its simplicity and excellent libraries. Python is crazily versatile and can be employed for nearly any kind of programming. From building small scale scripts that are intended to do banal tasks, to large scale system applications – You can use python anywhere and everywhere. In fact, NASA indeed uses Python for programming their equipment and space machinery.

Python can also be applied to process text, solve scientific equations, display numbers or images, and save data. In short, Python is used at the back of the scenes to process many elements you might need or encounter on your devices.

Why use Python for Ethical Hacking?

Python has gained its fame mostly because of its super powerful yet simple to use libraries. Sure Python has excellent readability, and it is straightforward, and all but nothing beats the truth that your role as a developer is made super easy with these libraries. These libraries find applications in all sorts of domains; for example, artificial intelligence has Pytorch and Tensorflow while Data Science has  Matplotlib, Pandas, Numpy.

Similarly, Python is brilliant for ethical hacking for the following reasons:

  • Useful python libraries like NetworkX, Pulsar, NAPALM, etc. making developing network tools a breeze
  • Ethical hackers commonly develop small scripts, and Python is a scripting language that provides impressive performance for small programs
  • Python has a vast community. Hence any doubt related programming is immediately solved by the community
  • Learning Python also gives you doors to various other career opportunities

 Demo: Dictionary Attack using Python

Let’s try a small demonstration as to how an ethical hacker may apply Python in his daily job. Suppose you were scanning for a 3-way handshake within an FTP server and a client, and you were victorious in doing so too. But as you guys might be aware, passwords are never really saved in plain text. They are always a hash form before being stored in a database, and usually, the hash itself is matched for verification reasons. Let us build a small Python program that can be applied to crack a password using the dictionary attack method.

 

import hashlib

 

flag = 0

 

pass_hash = input(“md5 hash: “)

 

wordlist = input(“File name: “)

try:

pass_file = open(wordlist,”r”)

except:

print(“No file found :(“)

quit()

 

for word in pass_file:

 

enc_wrd =word.encode(‘utf-8’)

digest =hashlib.md5(enc_wrd.strip()).hexdigest()

# print(word)

# print(digest)

# print(pass_hash)

if digest.strip() == pass_hash.strip():

print(“password found”)

print(“Password is ” + word)

flag = 1

break

 

if flag == 0:

print(“password not in list”)
