ChatGPT-6 Astra Cracks 1941 Enigma Message in Two Days
ChatGPT-6 Astra decrypted an 82-letter Enigma message sent to the SS-Totenkopf Division in 1941, a task that would take human researchers weeks or months.
An AI model has solved a World War II Enigma cipher that had remained unbroken for more than eight decades. ChatGPT-6 Astra decrypted the 1941 MVUEH message in just two days, according to Tom's Hardware.
The 82-letter cipher was sent by the German Army to the SS-Totenkopf Division on July 10, 1941. It had been shared online in 2005 and resisted all attempts at decryption until now.
Astra autonomously wrote Python and C++ software to build an Enigma simulator and an Enigma Bombe, the electromechanical device used by Allied codebreakers during the war. It selected MVUEH as a target and hypothesized a link to the plaintext of message Nr. 173, SIPVX.
The decrypted text reads approximately: "Please specify the route of march. I am in Rosenow, Rosenow. Immediate reply by radio." The original message contained a spelling mistake at the front.
Crypto Cellar researchers noted that the same task would take a human researcher weeks or months. The Enigma machine used three rotors chosen from five, a plugboard, and daily-changing settings.
Tom's Hardware previously reported that GPT6-Astra deciphered a 108-year-old WWI German ADFGVX-encrypted code.
