Challenge Description
After downloading the file using wget, we can run exiftool <file-name> to retrieve the flag, as both the description and the hint indicate that we have to examine the metadata of the file.
PicoCTF Hint: What does meta mean in the context of files?
Indeed, our flag is in the ‘Artist’ section of the file metadata.
