A morning in Mauritania (OSINT challenge)

I solved the OSINT challenge n°1 made by the renown analyst Sofia Santos. I will try to stick to the Intelligence Life Cycle as much as I can.

The plan

The collection and processing

The input image of the challenge where I highlighted the important parts:

Well, a lot of information can be noted, but careful none of these things can be actually be taken 100% for granted, but it gets us on track:

Interestingly, Yandex reverse image search yields a picture of Kiffa as first result, reducing bias induced by the text:

There’s only one match for “Kiffa” on Google Earth/Maps (in Mauritania).

First, I’m going to focus on the roads, looking for a paved one, perpendicular to the sun east-rising and passing through a green area, so I trigger Google Maps first and will switch to Earth when needing more precise imagery. Not much paved roads in Kiffa:

Switching to satellite view, this road matches with the requirements (going south, trees area on each side):

I hit Google Earth with an approximate GPS coordinates, do a 180° rotation and use the embed archive tool to view imagery closer to the date of the input (2013), the 2013 archive is less readable but the archive before (2010) is cleaner:

After a few seconds of wandering on this Mauritanian road, we can notice the pattern detected earlier. Buildings + big tree on the right, building next to an electric pole on the left, more electric poles along the road, paved road, in the right direction and going towards a greener area with a slight tilt to the right:

The top area is greener in 2013 and looks like more of the input:

So this is it, we supposedly have our place figured out. Now a few notes.

Calling out gaps

The reliability can be discussed here as the area lacks Street Views to produce an evidence that perfectly matches the input.

I’d score Reliability with 4/5 and Bias with 1.5/5.

We could investigate the scriptures on the left building, but again, lacking Street Views I’m not sure this would be helpful in our case.

Conclusion

This challenge was interesting as the area is really remote, and following the intelligence cycle has helped me to be more focused and critical towards the findings.
