ASN Enumeration

After this comes your second step ASN Enumeration Now what is this ASN? First of all we know that all companies or organization have their own unique ASN no which the identity of that company

Bug bounty methodology

In this case, subdomains can also be found using the same ASN no, but first you have to find ASN no, for this you can use the website bgp.he.net as you can see in the image. The website looks something like this

Here you have to give your target in the search box as you can see in the image, here you have got ASN no at the top, as well as you are getting ASN no show from different countries also, by clicking on these here, you can also get information gathering.

You may not have heard about the Reverse WHOIS before, but you can find it everywhere about the WHOIS record, but there is very little talk about what this Reverse WHOIS is, let us tell you about it.

Bug bounty methodology

For Reverse WHOIS you can use whoxy website, as in this article we are running the target of yahoo, there will also be the owner of yahoo, whose name you will get from google, find other subdomains by the same name.

As you can see in the image, you have to do the reverse WHOIS of your target while bug hunting, here you get the option to reverse WHOIS by company name, owner name, email address and domain keyword.

As you can see, you have also found out about other domains of your target by owner name, here you have to see which domain or subdomain that matches your target’s name, in this way, find the subdomain.


Subdomains can also be found by the shodan website in the bug bounty methodology. We all know about the shodan website, we use it to get the information of connected devices from the internet.

But shodan website can also be used to find subdomains, as you can see in the image, in this way you have to search query, here you have to signup first, only then you can search in this way.

Also you can view js files with the help of burp suite. When you look at the page source of any website, you get to see js files there and sometimes you also get to see vulnerabilities like information disclosure in js files.

That is why it is said that whenever you do bug hunting, in such a situation, you should explore your target for the most time because the possibilities of getting bugs can be from anywhere, so you have to observe everything carefully.

After this, your next step comes of subdomain enumeration and subdomain bruteforce, we have already told you about these, if you have not read our articles, then you must read them, you have been told to practically do it for subdomain scrapping You can also use the website. https://subdomainfinder.c99.nl/

Port Analysis

Like port 80 and port 443 are mostly open but there are many types of services that work on any other port, in such a case if it is open, then by bruteforce attack on it, if the password is found it Is called a valid bug

As you can see in the image, the first thing is to do port scanning, we have done this work using nmap, if you want, you can also use mass scan tool, it is your choice.

After doing all this, you have to save the report in xml file as you can see in the image, here we have saved the report of nmap in xml, similarly you have to save the file of your target as well.

After this you get a tool whose name is brutespray, you have to use it to do bruteforce attack on open services, if the password is found, you can report in such a way that you get bounty.
