As the British magazine The Economist recently wrote, the field of open source investigations has grown. Where there used to be a niche community of a relatively small number of people who had free time and a habit of sitting on the Internet for a long time, now there is a wide field of research and journalism, and OSINT techniques are used in various fields and institutions. It’s time to roll up your sleeves and start investigating. The beauty of open source investigations is that anyone (not just journalists or think tank researchers) can contribute to investigations that uncover criminal activity and help bring perpetrators to justice. When we say “anyone”, we really mean “anyone”: if you have access to the Internet, free time, and a stubborn desire to get to the truth, then you can become an open source researcher. Deciding to do such research can be difficult, especially if the field is completely new to you.
However, there is no need to worry: this guide provides concrete steps to help you develop the skills you need, find groups that match your interests, and ultimately help you with an important investigation. By following the steps below, you can learn where to find open source researchers, how to observe and learn from their work, and how to practice your new skills. And first of all, in this article, we will analyze how such simple things as Internet news can help you with this.
