Writeup of an OSINT challenge during Imaginary2023 CTF

OSINT

~1 minute

MISC(signpost) - (100pts) - 167 solves

For the only OSINT challenge in this CTF. We had to solve a GeoInt chall.

We had access to a signpost with 3 directions. The aim here was to find the latitude-longitude coordinates of the photo shot.

To avoid wasting too much time with google maps, I coinflip a google dork with the 3 stadium names such as: "seals stadium" "polo grounds" "scottsdale stadium"

Searching, I find :

with corresponding signs and description: Stadium direction signs at AT&T Park Stadium, San Francisco, California, USA, North America.

From there, it's very easy. Just search for the stadium on google maps and wander around until you find the viewpoint.
