Can you crack it (Part 3)

Well it looks like I am late to the party, I went back to the site and it’s closed.

That’s ok, we will keep going.

If you have not figured out what is contained in the image, it’s a….

> file test.exe
test.exe: DOS executable (COM)

I have recognized this from experience, if you want to see where file gets this from you can find it here.

less /usr/share/misc/magic
>0      byte            0xeb            DOS executable (COM)

Double check the file to make sure you have the correct hex entered in to the file, I had a mistake in mine.  The file command will still return a DOS exe if the whole file is not correct.  It only checks the first bits.
