Enjoy the last 24 hours :

The first puzzle involved finding prime numbers hidden within a seemingly innocuous image. The answer lay in steganography—a technique for concealing information—hidden inside that image. I received a phone call, followed by an official recruitment email, but that email has long since vanished. The prime numbers, in order, were: 307, 383, 503, 617, 743, 883, 1013. The second puzzle was a Caesar cipher, a simple encryption technique. The decrypted text read: "The answer is: 3301" The third and final puzzle involved decrypting an encrypted data file. (5) The decryption process required a combination of cryptographic techniques, including frequency analysis and cipher decryption. (6) The decrypted file contained a simple message: "WELL DONE, YOU HAVE PASSED THE TEST." (7) Cicada 3301. Damn cicada.
