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

Subdomain Takeover Scanning using Second Order
./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.
