File

The challenge contains a single file download; A file named cool_image.jpg.

The first thing I did, as with other forensics challenge is ran the file command.

$ file cool_image.jpg
cool_image.jpg: ASCII text

So its a text file. I tried opening the file

$ cat cool_image.jpg

Theres our flag.
