Kali Linux is a Debian-derived Linux distribution that is maintained by Offensive Security. It was developed by Mati Aharoni and Devon Kearns. Kali Linux is a specially designed OS for network analysts, Penetration testers, or in simple words, it is for those who work under the umbrella of cybersecurity and analysis. The official website of Kali Linux is Kali.org. It gained its popularity when it was practically used in Mr. Robot Series. It was not designed for general purposes, it is supposed to be used by professionals or by those who know how to operate Linux/Kali. To know how to install Kali Linux check its official documentation. Sometimes we have to automate our tasks while performing penetration testing or hacking as there could be thousands of conditions and payloads to test and testing them manually is a difficult task, So to increase the time efficiency we use tools that come pre-packed with Kali Linux. These tools not only saves our time but also captures the accurate data and output the specific result. Kali Linux comes packed with more than 350 tools which could be useful for hacking or penetration testing. Here we have the list of important Kali Linux tools that could save a lot of your time and effort.
Nmap is an open-source network scanner that is used to recon/scan networks. It is used to discover hosts, ports, and services along with their versions over a network. It sends packets to the host and then analyzes the responses in order to produce the desired results. It could even be used for host discovery, operating system detection, or scanning for open ports. It is one of the most popular reconnaissance tools. To use nmap:
- Ping the host with ping command to get the IP address
- Open the terminal and enter the following command there:
nmap -sV ipaddress
- Replace the IP address with the IP address of the host you want to scan.
- It will display all the captured details of the host.

2. Burp Suite
Burp Suite is one of the most popular web application security testing software. It is used as a proxy, so all the requests from the browser with the proxy pass through it. And as the request passes through the burp suite, it allows us to make changes to those requests as per our need which is good for testing vulnerabilities like XSS or SQLi or even any vulnerability related to the web. Kali Linux comes with burp suite community edition which is free but there is a paid edition of this tool known as burp suite professional which has a lot many functions as compared to burp suite community edition. To use burpsuite:
- Read this to learn how to setup burp suite.
- Open terminal and type “burpsuite” there.
- Go to the Proxy tab and turn the interceptor switch to on.
- Now visit any URL and it could be seen that the request is captured.
Wireshark is a network security tool used to analyze or work with data sent over a network. It is used to analyze the packets transmitted over a network. These packets may have information like the source IP and the destination IP, the protocol used, the data, and some headers. The packets generally have an extension of “.pcap” which could be read using the Wireshark tool. Read thisto learn how to set up and configure Wireshark. To use wireshark:
- Open Wireshark and download a demo pcap file from here
- Press”ctrl+o” to open a pcap file in wireshark.
- Now it can be seen that it display the list of packets along with the headers of these packets.
4. metasploit Framework
Metasploit is an open-source tool that was designed by Rapid7 technologies. It is one of the world’s most used penetration testing frameworks. It comes packed with a lot of exploits to exploit the vulnerabilities over a network or operating systems. Metasploit generally works over a local network but we can use Metasploit for hosts over the internet using “port forwarding“. Basically Metasploit is a CLI based tool but it even has a GUI package called “armitage” which makes the use of Metasploit more convenient and feasible. To use metasploit:
- Metasploit comes pre-installed with Kali Linux
- Just enter “msfconsole” in the terminal.
Aircrack is an all in one packet sniffer, WEP and WPA/WPA2 cracker, analyzing tool and a hash capturing tool. It is a tool used for wifi hacking. It helps in capturing the package and reading the hashes out of them and even cracking those hashes by various attacks like dictionary attacks. It supports almost all the latest wireless interfaces. To use aircrack-ng:
- aircrack-ng comes pre-compiled with Kali Linux.
- Simply type aircrack-ng in the terminal to use it.
6. Netcat Netcat is a networking tool used to work with ports and performing actions like port scanning, port listening, or port redirection. This command is even used for Network Debugging or even network daemon testing. This tool is considered as the Swiss army knife of networking tools. It could even be used to do the operating related to TCP, UDP, or UNIX-domain sockets or to open remote connections and much more. To use netcat:
- Netcat comes pre-installed with Kali Linux.
- Just type “nc” or “netcat” in the terminal to use the tool.
- To perform port listening type the following commands in 2 different terminals.
nc -l -p 1234
nc 127.0.0.1 1234
Read this for more information regarding netcat tool.
7. John the Ripper
John the Ripper is a great tool for cracking passwords using some famous brute force attacks like dictionary attack or custom wordlist attack etc. It is even used to crack the hashes or passwords for the zipped or compressed files and even locked files as well. It has many available options to crack hashes or passwords. To use John the Ripper:
- John the ripper comes pre-installed in Kali Linux.
- Just type “john” in the terminal to use the tool.
sqlmap is one of the best tools to perform SQL injection attacks. It just automates the process of testing a parameter for SQL injection and even automates the process of exploitation of the vulnerable parameter. It is a great tool as it detects the database on its own so we just have to provide a URL to check whether the parameter in the URL is vulnerable or not, we could even use the requested file to check for POST parameters. To use sqlmap tool:
- sqlmap comes pre-installed in Kali Linux
- Just type sqlmap in the terminal to use the tool.
Autopsy is a digital forensics tool that is used to gather information from forensics. Or in other words, this tool is used to investigate files or logs to learn about what exactly was done with the system. It could even be used as a recovery software to recover files from a memory card or a pen drive. To use autopsy tool:
10. Social Engineering Toolkit
Social Engineering Toolkit is a collection of tools that could be used to perform social engineering attacks. These tools use and manipulate human behavior for information gathering. it is a great tool to phish the websites even. To use Social Engineering Toolkit
- Social Engineering Toolkit comes pre-installed with Kali Linux
- Just type “setoolkit” in the terminal.
- Agree to the terms and conditions to start using the social engineering toolkit.
