15 Top Kali Linux Tools For Advanced Penetration Testing

Are you looking for the best Kali Linux tools? If yes, you have stumbled upon the right webpage. In this article, I am going to cover a list of the best Kali Linux tools.

So, without any further ado, let’s get started –

Kali Linux Tools – What do we know?💁

Kali Linux is one of the most popular and widely used operating systems for penetration testing and hacking. Even though it got popular amongst the general audience when they saw Kali Linux was practically used in the Mr. Robot series, it is not designed for general purposes.

Kali Linux is designed for people in the cybersecurity, analysis, and hacking industry, such as network analysts, penetration testers, hackers, and more.

Kali Linux is originally a Debian-derived Linux distro developed by Mati Aharoni and Devon Kearns, and currently, all the development of this tool is being managed by Offensive Security. However, due to its open-source nature, you can find many tweaked versions of Kali on the internet. You can even modify Kali to make it completely yours.

Kali Linux is such a popular operating system among hackers and security professionals because it has more than 600 pre-built penetration testing tools that can make the penetration testing process much faster. These tools not only let you automate the process and save time but also capture accurate essential data.

These tools can be categorized in a wide range of categories such as information gathering, wireless attacks, vulnerability analysis, web app penetration, exploitation tools, sniffing & spoofing tools, password attacks, and more. You can find the detailed list of these tools on Kali Linux’s official website.

One best thing about Kali Linux is that when you install it on your computer, it gets a very clean installation with very basic tools and a terminal. Even though there are over 600 tools, you won’t find them when you install Kali Linux. It happens so that your computer won’t get heavy with tools you won’t ever use.

Once you have installed Kali, you can use Kali Linux Metapackages to install a set of tools that you want to use. For example, if you are into wireless security and want tools to assess wireless security, you can install Kali and then use the kali-linux-wireless meta package only.

That said, if you are a beginner, you won’t need all of the Kali Linux tools installed on your system. This is the purpose of writing this article. This article has covered some of the best Kali Linux tools you can use, regardless of what metapackages they belong to.

So, here we go –

Best Kali Linux Tools – Our Top Pick👌👌

1. Nmap

Nmap, aka Network Mapper, is one of the most popular Kali Linux tools you can use. It is quite popular because it allows you to discover hosts and services on any computer network. Nmap does this by sending packets and then analyzing the responses it receives.
