SubOver

But something more awesome will come soon!

Subover is a Hostile Subdomain Takeover tool originally written in python but rewritten from scratch in Golang. Since it's redesign, it has been aimed with speed and efficiency in mind. Till date, SubOver detects 30+ services which is much more than any other tool out there. The tool uses Golang concurrency and hence is very fast. It can easily detect and report potential subdomain takeovers that exist. The list of potentially hijackable services is very comprehensive and it is what makes this tool so powerful.

You need to have Golang installed on your machine. There are no additional requirements for this tool.

go get github.com/Ice3man543/SubOver

NOTE - Do not change the location of providers.json file. Or the tool will not work.

Q: What should my wordlist look like?

A: Your wordlist should include a list of subdomains you're checking and should look something like:

backend.example.com
something.someone.com
apo-setup.fxc.something.com

Yes, you're probably correct. Feel free to:

• Not use it.
• Show me how to do it better.

• Add more services :-)
• Improve the tool (There are many things that can be done :-) )

Want to contribute? Great!

You can add more services or recommend any changes to the existing ones. Any kind of help is appreciated.

Or buy me a coffee \o/
