I have received numerous messages from people with their answer to the OSINT Olympics 2026 challenge. Not a single one so far was correct.
The problem is as old as time: confirmation bias.
I hope my upcoming video walkthrough makes sense, but in the meanwhile, here's a sneak preview.

My website has a new look!

This upgrade has been a long time coming as I often felt my "old" website was a bit crappy 😬

With so many daily users, I wanted to be able to provide a nicer experience, therefore I spent endless evenings and weekends learning and improving it bit by bit. I'm not a web designer so it's still not perfect, but I'm much happier with how it looks now.

Check it out! ❤️

Do you want to investigate possible human rights violations happening right now, in plain sight?

Protests in Iran are spreading across major cities & authorities are escalating efforts to suppress them.

In 2022, I published a practical guide on monitoring oppressive regimes using Iran as a case study. These methods & guidelines remain relevant & applicable across platforms.

If you are looking for a way to jump from theory to practice, this is a good place to start.

The answer to this OSINT challenge will reveal my favourite Christmas film of all time 😍

For one of my @OSINT4FUN's Advent calendar tasks, I wanted to add a twist. Instead of starting with an image or video, you begin with the coordinates. The problem is that these point to.. nothing..? 🤔

Enjoy and please, NO SPOILERS in the comments!
