Content Discovery - No 404 Status
In a perfect world all websites would respond correctly with the correct HTTP status codes

You'll notice that the "Page Cannot Be Found" page consistently has a file size of 669 bytes. Let's re-run the ffuf command but with the -fs switch which filters out any results that are 669 bytes in length.
This should cut the results down to just one file secret
