OSINT: Content Discovery
Course Overview
About This Free Course
OSINT (open-source intelligence) is not a single topic. It is, in short, open-source intelligence. OSINT is as old as the internet and goes by many names including intelligence gathering (IG), information gathering (IG).
The same techniques have been used by network administrators to monitor network traffic and detect intrusions, by social media analysts to monitor hashtags and topics on Twitter, in the military to monitor potential adversaries, and in marketing to monitor competitors.
In this course we'll focus on web servers. You will learn how to find hidden directories and files on any web server or website. You'll learn how to get access to older versions of a website, about web technologies, how to view HTTP headers and how to do automated scans.
Hackers will do content discovery as part of their hacking process, if they find a web server is running. From there, they may find out ways to exploit the scripts (php, node), find documents and more.
This is a beginners course, you don't need any prior knowledge. But, you should have Kali Linux at hands. Kali Linux is a free system designed for Cyber Security and Ethical Hacking, it has around 600 hacking programs. The easiest way to start it is from a USB disk or inside Virtual Box.
Who Should Take This Course
"OSINT: Content Discovery" is aimed at people who want a practical, structured introduction to udemy without paying full price for it. It's a solid fit if you're starting out in udemy and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 4.5/5 rating on Udemy. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a udemy course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether udemy is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
