Welcome to OSINT Exercise #026!
Task briefing:
The image below shows the contents of a zip file. Inside you will find a 31-second video recorded during a train ride, and four photos of undisclosed locations. They were all taken by the same individual in February 2024. Despite having no useful metadata, they still contain enough information to track down this person’s movements.
Your task is to determine:

Exercise level:
For beginners: a) Hard
For experts: a) Hard
Bonus challenges:

Why is my walkthrough not showing up above?
If you sent me your walkthrough and you do not see it on the list, here are the possible reasons:
• One or more of your answers were incorrect or missing.
• You asked me not to include it on the list, and I’m respecting your wishes.
• You may have sent me an incorrect or incomplete link.
• You linked to a website that tracks who sees your articles (e.g, LinkedIn).
• I suspected AI was heavily involved in the production of your walkthrough.
• I suspected you just wrote a walkthrough based on my video, and not your own work.
• I haven’t had the time to actually read, and add it yet (give me at least a week).
• I forgot about it (doesn’t usually happen, but I’m not flawless).
Why do some walkthroughs have a ⭐ in front of them?
The golden star emojis were introduced on the second year anniversary of OSINT Exercises. I will be adding them to walkthroughts that I feel stand out and deserve extra recognition. You can read more about my reasoning behind the decision in my blog post: “Two Years of OSINT Exercises: The Importance of Community Learning.”
