Blush. The video is a TEDx talk I did for TEDxTwenteU in 2025 about open source intelligence that designed and managed since 1990 for the Dutch Defence Intelligence Service for about 23 years. May be have a look? Let me know your thoughts or questions. More on OSINT training: https://www.opensourceintelligence.biz […]
The World Factbook (WFB) was a popular reference tool for country studies. First launched in 1962 as a printed, classified reference manual, it described in numbers and short texts, the economies, military, geography, agriculture, industries, society, government, people, memberships, energy, health and much more of all the countries in the world, as well as areas […]
In the meantime, AI agents behaviour is remarkbly similar. I use ChatGPT, Perplexity, Copilot and Gemini hoping that the answers from one will augment the answers from the others. Unfortunately, in my personal experience, that is not the case. Not only the answers are often identical, even the syntax grammar and writing style are identical […]
AI chatbots and LLM’s are an amazingly impressive development that will have a great impact on OSINT and intelligence analysis. Many of you use chatbots may be even on a daily basis for a variety of tasks and assignments, from simple ones to more complex things. And results can be surprising. That is, surprisingly good […]

Many cyber security firms focus on just two main items. The first is tools, technical stuff and software solutions, the other is rigidly ticking off checklists based on international standards and norms of which there are so many. Pretty easy to do and it has led to many cyber companies who may be classified as […]
So I ask OSINT students to solve a modest research assignment any way they see fit. They all listen carefully to me, then turn around to the computer screens and frantically start typing. After a few minutes I call them back to the central table to ask them what exactly they are doing, what is […]
Google has a few ways of limiting results by date. It used to be just using daterange: which required a Julian date. That has been replaced by before: and after: search operators. These can be used with a more readable data format such as: “border conflict” after:1995-05-02 before:1995-05-0 To limit results to just that time […]
The OSINT Bibliography now holds about 150 titles of reports, papers and books on open source intelligence. Most links are to the full text, but in cases of copyright I have linked the title to a purchase or library catalogue card. I have in addition added a How to use section to explain how to […]
