Struggled a bit with binwalk and used foremost. AND learned most from the comments. Thx
I have a related question to this challenge:
In this CTF we just had one picture to analyse. Assume you have hundreds and want to find out if something is hidden. How would you do this in a fast way?
I opened the file and saved a copy of it without changing anything (Linux Mint default picture viewer) and recognized that the file size changed. I compared this too a "normal" JPEG and there the filesize remained same.
Question: Would this be a reliable way to determine if something additionally is in the file? How would you do this?
