R3con1z3r – Lightweight Information Gathering Tool in Kali Linux
R3con1z3 is a free and open-source tool available on Github. R3con1z3 is one of the easiest and useful tools for performing reconnaissance on websites and web apps. The R3con1z3r tool is also available for Linux on Github. R3con1z3r is written in python language. You must have python language installed into your Kali Linux operating system. R3con1z3r provides a command-line interface that you can run on Kali Linux. This tool can be used to get information about our target(domain). We can target any domain using R3con1z3. The interactive console of R3con1z3 provides a number of helpful features that are helpful for security researchers.
R3con1z3 is based on Open Source Intelligence (OSINT). R3con1z3 is also called a lightweight Web information-gathering tool. R3con1z3r is also used to find footprints of the target. In terms of security, footprints are called a collection of every possible information regarding the target. R3con1z3r has a number of unique features that make this tool a lightweight tool. R3con1z3r has built-in functionalities which include passive reconnaissance Whois Footprinting, DNS information, Nmap port scanner, HTTP header flag, Traceroute, Reverse Target and hyperlinks on a webpage. As this tool is a lightweight tool it generated output in HTML format after the input domain is given in the input field of the tool.

Installation of R3con1z3 Tool
Step 1. Open your Kali Linux operating system. Move to desktop. Here you have to create a directory called R3con1z3. In this directory, you have to install the tool. To move to desktop use the following command.
Step 2. Now you are on the desktop. Here you have to create directory R3con1z3. To create R3con1z3 directory use the following command.
Step 3. You have created a directory. Now use the following command to move into that directory.
Step 4. Now you are in R3con1z3 directory. Now you have to install the pip command. Use the following command to install R3con1z3.
sudo apt install pip
Step 5. The pip command is being installed into your system. Now to install the R3con1z3 tool use the following command.
pip install R3con1z3r
Step 6. The tool has been downloaded and installed into your system. This is the time to run the tool. To run the tool use the following command.
Example: Use the R3con1z3 tool and scan the website testphp.vulnweb.com and find out open-ports, header information, etc. First we need to set our target using the following command.
r3con1z3r -d testphp.vulnweb.com
We can see that here all the scanning has been completed and an HTML report has been generated. To view, the report uses the following command. To view the report. Go to the tool directory, and you will find the whole report.
This is the HTML file that you have to open, and you will find the following similar kind of results.
