What is Subdomainizer?

Subdomainizer is an open-source tool designed for subdomain enumeration and discovery. It assists security professionals, penetration testers, and bug bounty hunters in identifying subdomains associated with a target domain. By discovering subdomains, users can uncover potential security vulnerabilities and attack vectors within an organization's infrastructure.

Subdomainizer utilizes various techniques, including passive reconnaissance, brute-force enumeration, and search engine scraping, to gather information about subdomains associated with a target domain.

Common Use and Commands:

Subdomainizer is commonly used to perform subdomain enumeration and reconnaissance. Below are some common commands and options used in Subdomainizer:

subdomainizer -d example.com -o output.txt

• -d: Specify the target domain to enumerate subdomains for (e.g., example.com).
• -o: Specify the output file to save the results (e.g., output.txt).

Additional options and flags include:

-h, --help            ---> Display help message and exit.
-v, --version         ---> Display version information and exit.
--all, -a             ---> Perform all available subdomain enumeration techniques.
--sublist3r           ---> Use Sublist3r for subdomain enumeration.
--findomain           ---> Use Findomain for subdomain enumeration.
--crtsh               ---> Use CRT.SH for subdomain enumeration.
--hackertarget        ---> Use HackerTarget for subdomain enumeration.
--threatcrowd         ---> Use ThreatCrowd for subdomain enumeration.

These options allow users to specify different subdomain enumeration techniques and customize their subdomain discovery process.
