Over the past half year, I’ve had the pleasure of Collaborating with Bellingcat as a contributor to their OSINT (Open-Source Intelligence) challenge platform.

For those who aren’t aware, Bellingcat is an independent investigative journalism group based in the Netherlands that publishes investigations using OSINT about war, human rights abuses and the criminal underground (this description is shamelessly stolen from the Wikipedia article as they describe it well).

This all started back in March 2025, when I published this challenge in their Discord community. The premises are simple: find where that scan was taken.
Just a few minutes later, already three people managed to find the location; a few days later even more. This challenge seemed well-received, and I was contacted by the Producer of Bellingcat to create a few more challenges for their Open-Source Challenges Platform.

All the challenges took half a year to collect, design; and over 6000 km of travel was needed within Europe.
Though I’m a bit sad some scans didn’t make the final cut (some of the ones I originally planned turned out worse than I imagined), the challenges turned good overall.

I want to thank Bellingcat for this opportunity to collaborate, and I encourage anyone to check out the Open-Source Challenge platform, and even donate to them. The challenge scans will be made available within Resonite in 6 months time from now.
