Kali Linux (earlier known as BackTrack) is a Debian-based distribution with a bundle of security and forensics tools. It features well-timed updates of security and a choice of four popular desktop environments. It also supports ARM architecture and flawless upgrades to newer versions. The popularity of Kali Linux grew when it was featured in multiple episodes of the Mr. Robot TV series. Tools that were featured in the show and are provided by Kali Linux are Bluetooth Scanner, Bluesniff, John the Ripper, Nmap, Shellshock, Wget, and many others.

Who Developed Kali Linux?

Mati Aharoni and Deavon Kearns are the leading developers of Kali Linux. It was a rewrite of Backtrack Linux, another penetration-testing-centric Linux distribution. Its development is set according to Debian standards as it imports most of its code from Debian repositories. The action was started in March 2012 by a small group of developers. Very few selected developers were allowed to commit packages in a protected environment. Kali Linux came out with its first release in 2013. Since then, Kali Linux has been through several significant updates. Offensive Security handles the result of these updates.

Why Do People Use Kali Linux?

There are many reasons why people use Kali Linux. They are listed below:

  1. Kali Linux has always been free to use.
  2. There are many tools that Kali Linux offers.
  3. Kali Linux follows a widely appreciated open-source model as it is a member of the very famous Linux family. Their development and the code can be publicly viewed on GitHub. 
  4. It supports multi-language. As we know that penetration tools tend to keep English only, but it has been ensured that Kali includes multi-language. This allows more and more users to operate in their mother language, and also it enables them to locate the tools as per their needs.
  5. It is entirely customizable. The developers in offensive security understand that everybody won't agree with their design model, so they have made it easy for everyone by making it customizable as per their liking.

System Requirements for Kali Linux

Installing Kali is very simple. All you have to ensure is that you have compatible hardware. Kali is supported on amd64, ARM (ARMEL and ARMHF)) and i386 platforms. The hardware requirements are significantly less. They are listed below. And as said Better the hardware Better the performance. 

  • Disk space of a minimum of 20 GB for the Kali Linux installer.
  • A RAM for amd64 and i386 architectures. A minimum of 1GB is required, and 2GB or more is recommended. 
  • CD-DVD Drive / USB boot support/ VirtualBox

How To Use Kali Linux Using Virtual Box?

The steps to install Kali Linux are listed below:

  • First, download the Virtual box and install it.
Step1 download virtual box
  • Download Virtual Box.
  • According to your operating system, select the correct package.
  • Proceed by repeatedly clicking next on the installer until you reach the Finish Button.

  • Now Virtual Box is successfully installed. Now move to the next step and download Kali Linux.
completion of virtual box
  • Download the Kali Linux package from its website.
  • Click VirtualBox → New. Choose the suitable virtual hard disk file and click Open.

  • Next, Click the Create button.
create os
  • Start Kali Operating System. The username and password are "root" and "tool" respectively.

You can now start working on Kali Linux.

List of Tools

Below is a list of tools pre-installed for ethical hacking, done by using Kali Linux. This list is not expensive as Kali has a lot of tools. Listing a few of them below: 



Network Mapper, also known as Nmap, is an open-source service for security auditing and network discovery. It uses raw IP packets in hidden ways to identify which hosts are available, what type of services they are offering, what operating systems they are managing, what type of packet firewalls are in use and many other characteristics.

Many network administrators find it useful for tasks like:

  • managing service upgrade schedules
  • monitoring host or service uptime
  • network inventory      




Aircrack-ng is a set of tools used to evaluate WiFi network security. It focuses on the key and vital areas of WiFi security:

  • Monitoring: The packet capture and exports the data to the text files for further processing by third-party tools.
  • Testing: Checking the WiFi cards and driver capabilities.
  • Attacking: De-authentication, fake access points, and others via packet injection.
  • Cracking: WEP and WPA PSK (WPA 1 and 2).

All tools are the command line which allows for heavy scripting. A lot of GUIs have also taken advantage of this feature. It works primarily on Linux and Windows, OS X, FreeBSD, OpenBSD, NetBSD, and Solaris.

Hydra is used to force crack a remote authentication service. It can perform rapid dictionary attacks against over 50 protocols, including telnet, HTTP, SMB, FTP, HTTPS, and many more databases. It can crack into packet crafters, wireless networks, etc.




WireShark is an open-source analyzer that is free of charge. With it, you can see the activities from a microscopic on a network level, including customizable reports, advanced triggers, alerts, etc. It is the world's most widely-used network protocol analyzer for Linux.


We have listed a few of the tools. Besides these, there are many other tools as well

Frequently Asked Questions

Why do hackers use Kali Linux?

Kali Linux is a free, convenient, and highly secure Linux OS. It also includes more than 600 tools for information security. Hackers often use Kali Linux because it has security analysis, auditing, and penetration testing.

Is Kali better or Ubuntu?

It comes with a less user-friendly Interface compared to Ubuntu. 8. Ubuntu is a good option for beginners in Linux. Kali Linux is an excellent option for those who are new to Linux.

Is Linux easy to hack?

Yes, Linux systems can be hacked. Even though they are very secure, hacking a Linux system is still possible.

Do hackers use Ubuntu?

Ubuntu is one of the best OS for hackers. Basic and networking hacking commands in Ubuntu are valuable to Linux hackers.

Is Kali good for programming?

Kali Linux is a top choice for programmers, developers, security researchers, and web developers. It's also a good OS for low-powered devices, as Kali Linux runs well on devices like Raspberry Pi.
