    Thats very strange for me but i cannot even connect to the challenge. Even curl (with any 0X parameter) hangs out. Could somebody PM me if that's normal case?

    If you need help with something, PM me how far you've got already and what you've tried. I won't respond to profile comments. And remember to +respect me if I helped you <3

  • Enjoyed the challenge @Xh4h, nice and easy, makes me feel smarter than I am :)

    @Kucharskov should be able to connect just fine with nc.

    Awesome!! Glad you like it :)

  • Nice challenge, I didn't really understand why the other menu options are there though. If you are stuck it's definitely worth thinking about the title of the challenge and how it might relate to the cryptosystem being presented!

  • Beautiful challenge. It took me a long time to study and taught me a few things about cryptography. Thanks @Xh4h

    I did it! Very cool challenge with some math ;)
    I already done an automation script for passing this challenge.

    That was Optimus Prime, and I send this message to any surviving HTB players taking refuge among the stars. He is here. He are waiting.

  • Hi guys, I'm very new to hack the box and I'm not sure how to connect to the challenge. If someone could point me in the right direction that would be much appreciated!

    You press the 'start' button and then use something like netcat together with the hostname (docker.hackthebox.eu) and the port provided. However, that said, if you are new to hackthebox I suggest you try an easier challenge first.
