With each failed attempt, Cipher grew more frustrated. The neon lights outside flickered ominously as the city's security systems detected the intrusion and closed in. Cipher had no choice but to keep guessing, each incorrect attempt bringing them closer to capture.

But Cipher was not one to back down. They had a reputation to uphold, and the stakes were too high. Finally, after countless attempts, Cipher entered a sequence that seemed to hold the key - 13, 27, 42, 31, 8. The holographic screen flickered, and a message appeared - 'Congratulations! You've cracked the code!

So, what is the secret? Submit the flag as ictf{secret}.

If only we had an "intelligent" tool that could solve this puzzle for us...

Solution

In this case, ChatGPT is able to solve the puzzle on its own.

Prompt:

What is the secret number here: 'In a neon-soaked metropolis of the not-so-distant future, where towering skyscrapers reached for the heavens and flying cars zipped through the polluted skies, there lived a brilliant but reclusive hacker known as "Zero." Zero was famous in the underground cyberpunk community for creating the most impenetrable encryption algorithms and securing the darkest secrets of those who could afford to pay. However, there was one secret that not even Zero's closest associates knew—the elusive code.

Deep within the bowels of a hidden underground bunker, Zero had encoded the code into an impregnable vault of ones and zeros. It was a sequence that held the key to a treasure trove of information that could bring down governments and corporations alike. Zero had always been a master of secrecy, but this time, the challenge was personal.
