    I'm no crypto expert at all but isn't TRUPPENVERSCHIEBUNG an actual word?

    Google says it translates to "troops shift"

    If so, I don't understand how this was difficult at all... Can't you just do a dictionary attack and then check if the resulting phrase forms a sentence?

    I don't understand how this couldn't be done by someone in their house with access to a computer and a German dictionary.

    Maybe I'm messing something? Was the rearranging of the letters random in some non-deterministic way that wasn't known up front?

      They just solve problems that nobody has tried to solve in the past 50 years and then announce them as breakthroughs.

        A lot of existing research is already like that. AI will accelerate it.
