• Rotor 2: I, Initial: Q, Ring A
• Rotor 3: III, Initial L, Ring A
• Reflector: UKW B
• Plugboard: BQ CR DI EJ KW MT OS PX UZ GH

Solution#

The challenge has conveniently provided all the necessary information to decode the ciphertext.

We turn to an online tool to decrypt a ciphertext using an enigma machine: Enigma Machine Decryptor

After decryption, the plaintext seems strange at the first glance.

Upon closer review, it becomes apparent that the words are improperly separated. Resolving that issue, we get the following comprehensible message and consequently, our flag.

message wrapped in light hidden deeper out of sight locking it more tightly anyway your flag is here flag fdfeabcacbebfbadaefbeccaadddbafezzz

Flag: flag{fdfeabcacbebfbadaefbeccaadddbafe}
