How I filtered out a whole chunk of 404 subdomains

Well, let me introduce myself first. My name is Vyshak. I am a beginner in this whole Ethical Hacking and Bug Bounty community and i wanted to give back something what i learned.

Recon is an important phase in either bug bounty and penetration testing. Subdomain enumeration is widely done by many in this recon phase.

While I am doing Subdomain Enumeration for my target, the list was way lot big than I expected.

But out of these 1465 subdomains, I need only those which has 200 response code, but it is a lot harder to find that manually. Doing some more research, I found a website which has become useful for me and I hope it will be useful for you guys also :)

btw, the website is https://httpstatus.io/

Here,you can paste upto 100 subdomains at a time. I use these websites to check status codes.

Guess what, out of those 1465 subdomains, only 12 of them got 200 status code.

I hope this blog finds helpful especially for beginners like me.Thank you.
