Working with SubExtractor Tool on Kali Linux OS

Example 1: Extracting Subdomains of w3wiki.org

python3 subextractor.py w3wiki.org

We have got the subdomains of the w3wiki.org parent domain. We can test these subdomains and find the security flaw in them.

Example 2: Extracting Sub-subdomains of cdn.w3wiki.org

python3 subextractor.py cdn.w3wiki.org

We have got the sub-sub domains of the cdn.w3wiki.org sub-domain. Many times a subdomain is also functionalist into the sub-sub domain which is rarely known to users. So we can enumerate and detect these sub-sub domains using the SubExtractor tool/

SubExtractor tool is an automated tool developed in the Python3 Language. This tool has the potential to extract subdomains of the parent domain. Not only these, but this tool can also extract sub-sub domains from a subdomain. This feature makes the tool unique from others. Many sub-sub domains can consist of sensitive data, so knowing the link to the sub-sub domain can expand the scope of the target, and the possibilities of finding the flaw increases. SubExtractor tool is available on the GitHub platform for free and is open-source to use.
