Bug hunting in zoom with ASN & CIDR - How to find them




Bug hunting in zoom with ASIN & CDR - How to find them?


So today we will know about the special technique of web penetration testing, which is named ASIN and CDR so, we will covered in this article about What is ASIN & CDR and How to find them ? How to find bug in zoom.us ? so, you can find in kali linux and windows also. so, lets get started!

ASN ( Autonomous system number ) ?

Autonomous system number is a uniqe number assignerd to an autonomous system ( AS ) by the internet assigned numbers authority ( IANA ).

An autonomous system number ( ASN ) is a way to represent a collection of IPs and who owns them.

An AS consists of blocks of IP addresses which have a distinctly defined policy for accessing external networks and are administered by a single organization but may be made up of several operators. Bug hunting in zoom with ASN & CDIR - How to find them

What is CIDR ?

A classless Inter-Domain Routing ( CIDR ) range is a short way of representing a group  of IP Addresses. Compromising a server hosted on a company's CIDR range may lead you directly into their internal network therefore these assests are considered critical and are ideal targets.

Example :- 192.0.2.0/24 for IPv4, and 2001:db8::/32 for IPv6.


So, first of all we will need some websites for find ASN and CIDR, like networks tool website and CIDR website and at the same time, we will also tell you that if you want to search bugs on facebook so, what is the privacy policy of facebook and according to which you can find bugs.


Look at the picture below and click on the link to see a privacy policy of facebook and how to find bugs and you will get reward...

To do bug hunting on any IP address, first you have to get the IP address of the main domain of an organization, company, social sites etc.

open your terminal in kali linux and Enter a command :

ping zoom.us





same command you will try in windows ( command prompt )


 ping zoom.us

 

Find ASN Number of any organization, company etc


All of your MX record, ASN number, DNS, blacklist and SMTP diagnostics in one integrated tool.  Input a domain name or IP Address or Host Name. Links in the results will guide you to other relevant tools and information.  And you'll have a chronological history of your results.

Go to this Link and select a ASN option and the IP address

For Example :  3.235.71.136











Total amount of IPs for this ASN: 1,048,576



In the above picture you can see here AS Name - amazon.com is visible while we have used the zoom application to find the ASN number from the IP address, but this happened because the zoom application itself  Due to lack of cloud service, amazon.com provides cloud service here which is a third party.


Now, we will copy a AS Number 14618 and once again search a ASN Lookup in the search box.









You can see the above image AS number, AS name is visible with CIDR range.

so, copy the CIDR range and go to this website link

Link :- https://ipaddressguide.com/cidr


Now, after copy the CIDR range, then you will calculate in the CIDR To IP Range...




After calculating ...




You can see here the result is given here CIDR range, Netmask, Wildcard bits, First IP, First IP ( Decimal ), Last IP, Last IP ( Decimal ) and total host...

Hey wait wait...

Now I tell you where you will use these IP's ( first IP, Last IP etc ), you can use the network mapper( Nmap ) tool with this IP, you can find which ports are open on this IP address like SSH, DNS, HTTP, SQL ETC.



I hope you liked this post, then you should not forget to share this post at all.
Thank you so much :-)
