Linux-based distros are the most preferred platforms for ethical hacking. Specifically, open source operating systems like Kali Linux Tools and Parrot are very popular among security researchers. They come with a long list of hacking tools with Terminal and GUI interfaces.

In this article, I’ll be listing the best Kali Linux tools for 2019 that you can use on Linux operating system. I’ve chosen the most popular tool for each category of security tools and described their main highlights.

Kali Linux Tools

1. Nmap

Nmap or “Network Mapper” is one of the most popular tools on Kali Linux for information gathering. In other words, to get insights about the host, its IP address, OS detection, and similar network security details (like the number of open ports and what they are).

It also offers features for firewall evasion and spoofing.

2. Aircrack-ng

Aircrack-ng is one of the best wireless password hack tools for WEP/WAP/WPA2 cracking utilized worldwide!

It works by taking packets of the network, analyses it via passwords recovered. It also possesses a console interface. In addition to this, Aircrack-ng also makes use of standard FMS (Fluhrer, Mantin, and Shamir) attack along with a few optimizations such as the KoreK attacks and PTW attack to quicken the attack which is faster than the WEP.

If you find Aircrack-ng hard to use, simply check for tutorials available online.

3. Wireshark

For iformation Gathering

If I say that Wireshark is one of the most used network protocol analyzers around, I won’t be wrong. This free and open source Kali Linux hacking tool uses the Qt widget for its interface. With this tool, you can take a closer look at what’s happening on your network with the support for hundreds of protocols. It also brings along live capture and offline analysis. The captured files are compressed using gzip and they can be easily decompressed or exported to formats like CSV, XML, PostScript, or plain text. For the die-hard lovers of Terminal-based tools, there’s a non-GUI version named TShark as well. Using this tool, an ethical hacker can read the live traffic or analyze the already-captured packets. What makes Wireshark more useful is its cross-platform availability for Linux, macOS, Solaris, BSD, etc.

 4. WPScan

The first one on our list of best Kali Linux Hacking tools is the WPScan. WordPress is indeed one of the best security auditing tools. For those using WordPress, like bloggers, WPScan is the best option to go for since it also enlists the detailed plugins that are active.

With WPScan, makes WP less vulnerable and ensures the safety of your blog. This is a free tool but is not open source. It does all the scanning required and works effectively as well.

5. Metasploit Framework

For Exploitation Tools

The Metaploit Framework needs no introduction as it’s the world’s most used penetration testing platform. It lets you spot, validate, and exploit different loopholes. It’s also used as a base for many commercial ethical hacking frameworks. Being an open source framework, the open source community keeps adding newer modules and Rapid7 also keeps adding new features on its own. What makes it even more interesting is the fact that new updates to this tool are pushed every day. You can install Metasploit on Linux, Windows, macOS, and BSD.

6. Nessus

kali linux hacking tool

Nessus tool helps users scan the computers for vulnerabilities. It is more of a remote scanning tool that does not block the scanned vulnerabilities. However, by running 1200+ vulnerability scans, it can take them out by sending alerts whenever security patches are required to be made.

So Nessus could be a great option if you want to find vulnerabilities of a Network on which the computer is connected.

This way the computers connected to one network connection can be easily secured. The only drawback that hits us here is, Nessus is no more a free tool.

You will have to pay after a free trial period of 7 days.

 7. Netcat


NC or Netcat is one of the Kali Linux tools that can be used for creating almost any sort of connections. You can make use of this network utility for using the IP/TCP protocols for reading and writing the data across network connections.

This tool can be used for exploring and debugging numerous networks with the use of port-scanning, tunnel mode, and so on. So what are you waiting for? Go grab the amazing Kali Linux hacking tool.

8. John the Ripper

John the Ripper is another popular cracking tool used in the penetration testing (and hacking) community. It was initially developed for Unix systems but has grown to be available on over 10 OS distros.

It features a customizable cracker, automatic password hash detection, brute force attack, and dictionary attack (among other cracking modes).

9. Burp Suite Scanner


A professional integrated graphic user interface tool that is used for scanning the vulnerabilities regarding the security of web apps is the Burp Suite Scanner. This tool is quite different from other web security analysis tools and is not an open source tool.

You will be offered a Graphic User Interface along with a number of features here. This can work for rudimentary purposes. However, if you are looking for professional features, you will have to upgrade.

10. Wifite2

Wifite2 is a free and open-source Python-based wireless network auditing utility tool designed to work perfectly with pen-testing distros. It is a complete rewrite of Wifite and thus, features an improved performance.

It does a good job at decloaking and cracking hidden access points, cracking weak WEP passwords using a list of cracking techniques, etc.

11. Social Engineering Toolkit (SET)

Social Engineering Toolkit

If you are into pretty serious penetration testing stuff, this should be one of the best tools you should check out. Social engineering is a big deal and with SET tool, you can help protect against such attacks.

12. Nikto


The last one on our list of best Kali Linux Tools is the Nikto open-source web scanner that performs comprehensive testing against web items. It is mostly used in case of web applications. It is an open source vulnerability scanner.

This tool works by the mechanism of checking through various outdated program versions, server-oriented issues, vulnerable server configurations, and so on.

Various features like host authentication, SSL, proxies, attack encoding, etc. can be seen in this tool. Thus it is used by ethical hackers for locating insecure configurations, programs, and files, etc.
