Latest model ChatGPT-6 Astra managed to crack an 85-year-old message sent by the German army on July 10, 1941, encrypted using the world's most famous encryption machine, the Enigma, in just two days. This 82-character cipher was called MVUEH and people have been trying to decipher it since 2005. The message appeared on the specialized website Crypto Cellar Research in 2005. Both professional and hobby cryptographers from all over the world tried to decipher the message, but no one succeeded. Until now, Carter Leffen used artificial intelligence. The model he used was specifically GPT-6 Astra from OpenAI, which is freely accessible.
It first mapped the context and focused on another, already cracked message from the same day that MVUEH was sent. The model then autonomously programmed its own Enigma emulator and a software equivalent of the Bomba electromechanical decryption machine, using which it searched for the correct key combination. Nakonec managed to break the cipher after 48 hours, even though it contained typos that occurred when the message was sent. In addition, the message used nestThe standard order of the Enigma rotors. Despite everything, the AI managed to break it, and we now know that the supply section of the SS-Totenkopf division requested an immediate dispatch of the march route.
