Lab Description

In this lab, you will explore both manual and automated approaches to subdomain enumeration using the crt.sh service. Starting with manual searches, you’ll analyze SSL/TLS certificates to uncover subdomains linked to target domains. The results will be processed using LibreOffice Writer for organization and review.

You’ll then shift to automation by creating and running a bash script that performs the same subdomain extraction at scale, improving efficiency and minimizing manual effort. This dual approach mirrors real-world practices in reconnaissance, supporting tasks such as asset discovery, vulnerability assessment, and threat hunting. By combining analysis with automation, this lab helps you build foundational skills in subdomain intelligence and data processing.
