Challenge Statement

I know it’s an esoteric challenge for a Capture the Flag, but could you herd these cows for me?

Solution

After downloading the file given and reading it, I found it filled with variations of moo, ooo, mmo and so on.

Since I spend some time with esoteric languages I recognized this as a programming language called COW. So all I did was find an online code execution environment and ran it. I used this from JDoodle and got the flag.
