We have to find a clue about a guy that probably committed suicide, and only a FAT image file (from his phone) is provided. This challenge is very easy if you are lucky to find the key, but it can take a lot of time if not, because we don’t know exactly what we are looking for.
I started opening the mail and web cache files, but there was a lot of garbage, so I decided to change the strategy, opening the entire volume directly in a hex editor and searching for terms like “suicide”. Then, I found some more garbage, but fortunately in the same fragment (very close to this word), I saw a Google search with an odd string (where can i buy potassium cyanide), and this was the key of the challenge.
