Warp Terminal

If you read the Kali Linux review, you know why it is considered one of the best Linux distributions for hacking and pen-testing and rightly so. It comes baked in with a lot of tools to make it easier for you to test, hack, and for anything else related to digital forensics.

It is one of the most recommended Linux distro for ethical hackers. Even if you are not a hacker but a webmaster – you can still utilize some of the tools to easily run a scan of your web server or web page.

In either case, no matter what your purpose is – we shall take a look at some of the best Kali Linux tools that you should be using.

Non-FOSS Warning! Some of the applications mentioned here are not open source. They have been included in the context of Linux usage.

There are several types of tools that comes pre-installed. If you do not find a tool installed, simply download it and set it up. It’s easy.

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. Lynis

Lynis is a powerful tool for security auditing, compliance testing, and system hardening. Of course, you can also utilize this for vulnerability detection and penetration testing as well.

It will scan the system according to the components it detects. For example, if it detects Apache – it will run Apache-related tests for pin point information.

3. WPScan

Wpscan Kali Linux

WordPress is one of the best open source CMS and this would be the best free WordPress security auditing tool. It’s free but not open source.

If you want to know whether a WordPress blog is vulnerable in some way, WPScan is your friend.

In addition, it also gives you details of the plugins active. Of course, a well-secured blog may not give you a lot of details, but it is still the best tool for WordPress security scans to find potential vulnerabilities.

4. Aircrack-ng

Aircrack Ng Kali Linux Tool

Aircrack-ng is a collection of tools to assess WiFi network security. It isn’t just limited to monitor and get insights – but it also includes the ability to compromise a network (WEP, WPA 1, and WPA 2).

If you forgot the password of your own WiFi network – you can try using this to regain access. It also includes a variety of wireless attacks with which you can target/monitor a WiFi network to enhance its security.

5. Hydra

Hydra Kali Linux

If you are looking for an interesting tool to crack login/password pairs, Hydra will be one of the best Kali Linux tools that comes pre-installed.

It may not be actively maintained anymore – but it is now on GitHub, so you can contribute working on it as well.

6. Wireshark

Wireshark Network Analyzer

Wireshark is the most popular network analyzer that comes baked in with Kali Linux. It can be categorized as one of the best Kali Linux tools for network sniffing as well.

It is being actively maintained, so I would definitely recommend trying this out. And it’s really easy to install Wireshark on Linux.

7. Metasploit Framework

Metasploit Framework

Metsploit Framework is the most used penetration testing framework. It offers two editions – one (open source) and the second is the pro version to it. With this tool, you can verify vulnerabilities, test known exploits, and perform a complete security assessment.

Of course, the free version won’t have all the features, so if you are into serious stuff, you should compare the editions here.

8. Skipfish

Skipfish Kali Linux Tool

Similar to WPScan, but not just focused for WordPress. Skipfish is a web application scanner that would give you insights for almost every type of web applications. It’s fast and easy to use. In addition, its recursive crawl method makes it even better.

For professional web application security assessments, the report generated by Skipfish will come in handy.

9. Maltego

Maltego

Maltego is an impressive data mining tool to analyze information online and connect the dots (if any). As per the information, it creates a directed graph to help analyze the link between those pieces of data.

Do note, that this isn’t an open source tool.

It comes pre-installed, however, you will have to sign up in order to select which edition you want to use. If you want for personal use, the community edition will suffice (you just need to register for an account) but if you want to utilize for commercial purpose, you need the subscription to the classic or XL version.

10. Nessus

If you have a computer connected to a network, Nessus can help find vulnerabilities that a potential attacker may take advantage of. Of course, if you are an administrator for multiple computers connected to a network, you can make use of it and secure those computers.

However, this is not a free tool anymore, you can try it free for 7 days on from its official website.

11. Burp Suite Scanner

Burp Suite Community Edition

Burp Suite Scanner is a fantastic web security analysis tool. Unlike other web application security scanner, Burp offers a GUI and quite a few advanced tools.

However, the community edition restricts the features to only some essential manual tools. For professionals, you will have to consider upgrading. Similar to the previous tool, this isn’t open source either.

I’ve used the free version, but if you want more details on it, you should check out the features available on their official website.

12. BeEF

Beef Framework

BeEF (Browser Exploitation Framework) is yet another impressive tool. It has been tailored for penetration testers to assess the security of a web browser.

This is one of the best Kali Linux tools because a lot of users do want to know and fix the client-side problems when talking about web security.

13. Apktool

Apktool

Apktool is indeed one of the popular tools found on Kali Linux for reverse engineering Android apps. Of course, you should make good use of it – for educational purposes.

With this tool, you can experiment some stuff yourself and let the original developer know about your idea as well. What do you think you’ll be using it for?

14. sqlmap

Sqlmap

If you were looking for an open source penetration testing tool – sqlmap is one of the best. It automates the process of exploiting SQL injection flaws and helps you take over database servers.

15. John the Ripper

The official website mentions the procedure to get it installed if you don’t have it already.

17. Autopsy Forensic Browser

Nikto is a powerful web server scanner – that makes it one of the best Kali Linux tools available. It checks in against potentially dangerous files/programs, outdated versions of server, and many more things.

20. Yersinia

Yersinia

Yersinia is an interesting framework to perform Layer 2 attacks (Layer 2 refers to the data link layer of OSI model) on a network. Of course, if you want a network to be secure, you will have to consider all the seven layers. However, this tool focuses on Layer 2 and a variety of network protocols that include STP, CDP, DTP, and so on.

21. 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.
