I'm excited to announce I'll be speaking at @defcon.bsky.social #ReconVillage this August! My talk, "OSINT Is Still a Thinking Game," explores how AI dependence is eroding our tradecraft - and how to fight back. See you in Vegas. #DEFCON34 #ReconVillage #OSINT #CyberSecurity
Taking the new biscuit pro for a (war)drive. Wifi / BLE sniffing is a highly overlooked technique within #osint research and investigations. Nerds gonna nerd 😎
The @SANSInstitute #OSINT summit #Amsterdam is about to get started and sold out. Day 1 workshops, day 2 talks. I’ll be having a ton of fun chairing this together with Matt Edmondson. Looking forward to see old friends and make a bunch of new friends.
A horrific #Belfast stabbing shows why responsible OSINT matters. Starting with one BBC article + basic Google searches, I used ShadowDragon Horizon to map public online signals around the suspect Not hacking. Not guessing. Just OSINT. www.bbc.co.uk/news/article... #OSINT #ShadowDragon

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...
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...

Some people online are claiming that #Kirk was shot up close by a man standing next/close to him. This is not true. After the impact you can clearly see his right hand is empty, NO GUN. #OSINT #CharlieKirk
Morning coffee, skimming the news. This article about the arrest of a serial killer caught my attention : nypost.com/2025/09/08/u... Decided to use our #OSINT enterprise solution @shadowdragonio.bsky.social to see if I could learn about the suspect. Couple of minutes I was able to uncover A LOT !
New Blog: Discover how graffiti serves as modern hieroglyphics in #OSINT. Explore graffiti's role in gang communication and territorial markers today. www.dutchosintguy.com/post/osint-r...
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...
Cooking up a new sun and moon shadow-cast calculator for #OSINT investigations. Looking for input for (advanced) features.... anyone? See screenshots of work in progress:
