Locate Me
Sherlock is investigating a kidnapping case and managed to retrieve an image from the hard drive of a suspect. Could you help Sherlock find the location from this image? Once the location is determined, supply the Plus Code to the compute_flag.py script and retrieve the flag.
This challenge gave us TWO files to work with;
compute_flag.py
locate_me.jpg
From the hint given, we have to somehow find the Plus Code, and in order to get the Plus Code, we have to first find the location.
We took a look at the .jpg file and there is nothing out of the ordinary. We suspected that this could be another form of Steganography! So, we used an online Steganography tool, called Aperi'Solve, that performs layer analysis on an image.
Unfortunately, there were nothing of interest. 😭
We figured that since it is an image, maybe we should check out the metadata! We used exiftool to see the metadata results.
exiftool locate_me.jpgInterestingly, there were a lot of metadata information given! GPS Position is what we took note of.
We took the Latitude(55.20) and Longitude(22.80) and searched it on Google Maps.
We copied the Plus Code and served it to the compute_flag.py and we got the flag!!! 🎉
