New Blog: AI isn’t just supporting OSINT — it’s distorting it. Hallucinations, poisoned data, synthetic narratives… and leadership often can’t see it happening. My new blog digs into this shift with examples, risks, and what must change. 📘 Read here: www.dutchosintguy.com/post/critica...

New Blog: More OSINT tools. More dashboards. Less actual reasoning. AI didn’t break OSINT, it revealed a problem that was already there. OSINT is still a thinking game. Read it here: www.dutchosintguy.com/post/osint-i...

New Blog: OSINT isn’t getting harder because investigators lack tools. It’s getting harder because the internet is becoming adversarial: disappearing data, closed platforms, AI deception. The next phase of #OSINT will be about judgment, not dashboards. www.dutchosintguy.com/post/the-nex...

🚨New blog: A city is not a word. It’s a language system. When people say “020,” “Mokum,” or “Freedom City,” they’re still talking about Amsterdam just not in a way your #OSINT investigation understands. Imagine how many you’re missing. Read the blog here: www.dutchosintguy.com/post/how-osi...

🧵 1/14 2025 wasn’t a writing exercise for me. It was a warning. Across every blog I wrote this year, one pattern kept repeating: OSINT doesn’t fail because we lack data, tools, or AI. It fails when we stop thinking.

Happy #OSINT holidays to all my followers and friends !

#HUMINT is human truth. #OSINT is digital truth. Neither makes sense without the other. I wrote about this in my latest blog. What I’ve seen work, what I’ve seen fail, and why intelligence today is never one discipline alone. www.dutchosintguy.com/post/when-hu...

This is why I love working for @ShadowDragonIO. We build #OSINT capabilities that help uncover real world criminals. This use case started with one FBI Most wanted page: www.fbi.gov/wanted/cyber... Park Jin HYOK is wanted by the FBI for his role as a hacker for #DPRK. 1/3

New Blog: Fatigue is the invisible corruption of intelligence work. It dulls intuition, erodes skepticism, and makes analysts trust tools more than their own reasoning. #OSINT doesn’t fail when data runs out. It fails when curiosity does. Read: www.dutchosintguy.com/post/black-s...

New Blog: Most people doing #OSINT aren’t doing OSINT. They’re just Googling with extra steps, screenshotting dashboards, and calling it “intelligence.” That’s not tradecraft. That’s cosplay. Let’s talk about what OSINT is not: www.dutchosintguy.com/post/stop-ca...
