Subdomain Takeover Scanning using Second Order: Brilliant and Free tool to use in 2024

Hey Hackers,
Greetings of the day. Today we’ll be learning about another yet important tool that is Second order that will help in detection of subdomain takeover flaws and much more so let us get started.

What is Second Order? Subdomain Takeover Scanning using Second Order

Second order is a tool that is open source written in golang. The tool comprises of various config files that is used while scanning for subdoomain takeover, crawling and collecting sensitive parameters for testing purposes.

So let’s go forward and set this tool on our system

Installing and setting up

So in order to install this tool make sure golang is installed in your system for that use the following command

sudo apt-get install go 

And to verify the installtion use the version command

go version 

Well it is installed let’s move to the next step

Cloning Second-Order

So in order to clone the second order repository use the following go command

go install -v github.com/mhmdiaa/second-order@latest

The tool has been successfully installed on the system to verify the installation use the -h switch to check the help menu

./second-order -h

Using Second-Order

Performing scanning : takeover.json

So in order to perform scan on a target site use the following command

./second-order -target https://hackingblogs.com -config config/takeover.json

Here the takeover.json config file is used to initiate subdomain takeover scanning on the site hackingblogs.

Performing scanning : parameter.json

So we use this config file when we are crawling the site and want to dig interesting paramters on the site this can be done using the following command

./second-order -target https://hackingblogs.com -config config/parameters.json

Performing scanning : header.json

So to find the headers (Http headers) we’ll be using the headers.json config file and the command that we’ll be using will be

./second-order -target https://hackingblogs.com -config config/Headers.json

Now you show me how you will be performing scans to dig javascript from the website

Conclusion

As you see the tool will be helpful for bug hunter in order to find and detect flaws, find paramters etc. The tool offers variety of scanning try to use the other json files and analyse the result, that is it and i’ll come back again.

Keep the fire and Learn. Hacking is an Art and a Hacker is an Artist.
