Cattle (Warmups)

Part of the Huntress CTF 2024

Description

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

Attachements

cattle

Solution

After downloading the file and running file - it turns out to be a simple text file.

Let's open it up and see what's inside.

😂 It's COW!! I've dealt with this in the past, due to other CTFs. COW is a programming language, and a variant of the Brainfuck language. These are both popular in CTFs. I've linked the wiki page for both above, so you can get more information if you are curious.

Since we have actual COW code, let's load up a web-based COW code intepreter and see what the output is. I'll be using CacheSleuth's Cow Code Interpreter.

Load the COW Code into the Ciphertext box and hit Decrypt. It gives us the flag we are looking for.

🐄 Moo, ya'll. 🐄

Just For Fun: Convert this message I made for you.
