I have received numerous messages from people with their answer to the OSINT Olympics 2026 challenge. Not a single one so far was correct.

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! ❤️

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