Solution

Because of the title I figured this was a Caesar Cypher and I used this website to decipher the code. It lists all possible shifts using the alphabet, giving me these results:

I knew the first 3 letters were "ctf" because this is the code for the flags they have been using, which means the 5th entry is the correct one.

Additional information

The Caesar cipher is a classic example of ancient cryptography that involves shifting each letter of a plaintext message by a certain number of letters. It is a type of substitution cipher where one letter is substituted for another in a consistent fashion.

The method is named after Julius Caesar, who used it in his private correspondence.
