Almost forgot to share my latest Bellingcat challenge I completed last week.

This one’s a good reminder that partial text can be incredibly helpful, but you still need to independently verify plausible answers.

And of course, checking the obvious data sources early is still a good idea even if they give you bugger all in terms of useful information.

Anyway, here’s the writeup if you fancy reading it.

Getting back into Bellingcat challenges after far too long.

I solved one today involving image metadata, GPS coordinates, a very foggy airfield, and the mildly embarrassing realisation that I already had the exact EXIF tool I needed installed on my PC. 😅

Anyway, I wrote up the process, including the wrong turns. If you fancy giving it a read, here’s the link: https://medium.com/@kdmurdock/lost-in-the-fog-turning-uncertainty-into-investigation-d487b4776b6d?sharedUserId=kdmurdock
