Patriot CTF: My phone!
This was a simple Crypto challenge where we had to figure out the location of a phone thief, that was encrypted by a odd cipher.
The Challenge
Solution
I first just searched up symbol ciphers but I was confused between Blitz Cipher and Bill’s Cipher as they both look kind of familiar.
After thoroughly looking through the ciphertext and what was stated in the challenge. I realised that the location was encrypted using Bill’s Cipher and that is because in Gravity Falls a triangular shaped demon is named Bill Cipher.
With the help of a online decoder website called dCode I was able to decrypt the ciphertext and the plaintext is shown below:
They look like coordinates right? Yes, so I just typed them inside google maps and got the name of the city where the phone thief was in.
