What you will learn - It will give you a brief overview of OSINT, note taking, sock puppets, google dorks, reverse image searching, geolocation, breached data, people search engines and social media OSINT.
Review/Personal Opinion -
It’s one of the most popular free courses and it’s loved by beginners. I have completed this course back in 2021 when i was a complete beginners in OSINT and I really liked. It gives you a rough idea of what you are going to learn in this domain, so I genuinely recommended this course. But I also believe, this course is over hyped, many people recommended this course as a beginner would become expert by completing this little course. It will just give you an introduction to different topics in OSINT, don’t keep any high expectations from it.

This is one of my favorite playlists which is still my first recommendation when someone asks me resources for learning GeoINT. Every new video of the playlist has something new to teach and I am follower of this person from my early days when i was new in OSINT.

This is an amazing playlist of some awesome videos created by OSINT Curious, which was run by some amazing OSINT Experts like Sector035, Wondersmith Rae, OSINT Techniques and some others.

Course Duration - Depends on you
Target Audience - Beginners
What you will learn - It is a learning-based course. You will be doing challenges on the topics and tools like The Harvester, TweetDeck, Google Dorks, OSINT Framework, Reverse Image Searching.
Review/Personal Opinion -
This is not a course which will teach you from the basics, instead it’s a learning-based course which will teach you how to apply OSINT for solving problems in CTFs and in real world. Start this course, when you have foundational knowledge of OSINT or in other words, when you have completed the three above mentioned courses. I really suggest this course as it will teach you how to tackle the problems and how to think.

Review/Personal Opinion -
When I completed this course last year, i loved this as it’s an interactive, rather than watching some boring videos, i was solving case with my learning and knowledge in OSINT. I highly recommend this course as it simulates a real-world investigation and gives you the confidence in your skill when you finish the course.

Review/Personal Opinion -
I would recommend this course to those who wants to learn how to use Maltego as a tool for their Investigations, this course have enough resource to get started with Maltego and Personally I would suggest to go through this course because Maltego is a highly used tool in the industry and learning how to use it will help you a lot.
So, these are my favorite course which i suggest to any beginner who approached for asking for resources. There are many other free courses and playlists for OSINT, some of them will be good and some will be bad too. But i only recommended those resources which I myself have used or am sure of their quality. I don’t want to give any bad advice or any advice which can be harm anyone in the future.
