Bruno Borges, a Brazilian student who has mysteriously vanished from his home, left behind numerous encrypted notes. Now a Brazilian newspaper reports on new activities in this case.

It’s a situation I encounter once in while. A blog post I wrote some time ago suddenly becomes extremely popular, and the page views are skyrocketing. Sometimes the reason for this popularity is clear. For instance, whenever one of the two Zodiac Killer movies is shown on TV, my Zodiac articles receive many views. In other cases I don’t know what caused so many people to suddenly read an old article of mine.


The Bruno Borges case

This morning I encountered such a situation again. When I looked at the web statistics, I saw that thousands of people had called a blog article I had written two months ago. It is about Brazilian student Bruno Borges, who vanished from his home and left behind encrypted notes. The following picture of him is taken from Facebook.


Bruno Borges, a 24 year old psychology student from Brazil, was working on some “alien project” when he mysteriously vanished in early April. He was known among his friends as an alien enthusiast. The student’s disappearance sparked worldwide interest – with some even believing he was abducted by aliens. A bizarre video of the inside of his bedroom was leaked online. Apparently, Borges had turned his room into a shrine to the extraterrestrial world. He removed all the furniture and put up an expensive statue of Giordano Bruno.

What makes Borges’ vanishing interesting for this blog is the fact that the walls in his room have been found covered with encrypted writing. In addition, Borges left behind 14 encrypted books.

The code Borges used for the major part of his notes is solved. It’s a simple substitution code (i. e., a monoalphabetic substitution cipher, also known as MASC). Check here for details.

However, there are a few text passages encrypted in a different code. To my knowledge they are still unsolved. Here’s the first part:


Here’s the second part:


If a reader can break this encryption or if a solution is already available somewhere, please let me know.


News from Brazil

The vanishing of Bruno Borges happened more than two months ago. So, why is there so much interest in my Borges article from April today?

According to Google News, the Brazilian news portal Globo has published three articles about the Borges case in the last two weeks. Google News shows no other media coverage of this story for this time period. Unfortunately, these articles are written in Portuguese – a language I don’t understand. Using Google translate I tried to figure out what these articles are about. Here’s the result:

  • Article 1 (2017-06-02): A friend of Bruno Borges, who had been questioned by police before, was questioned again.
  • Article 2 (2017-06-07): Police tried to interrogate another friend of Bruno Borges, who was also heard before, but to no avail. The two friends might have stolen something from Borges and made false statements.
  • Article 3 (2017-06-11): This seems to be a summary of the first two articles.

Is there more new information about the Borges case? Why have so many people called up my old Borges post today? Was the Borges case mentioned on TV somewhere yesterday? If somebody knows more, please tell me.

    OK, so I asked some people in the Forum about Bruno. He is alive and doing well, even if nobody knows his whereabout. Police found in his friend’s house some of Brunos belongings, and also a contract signed with a small group of friends, talking that they will share profit from his books. All these signs caused police to stop follow the case, not being suspected as kidnapping anymore. But many people aren’t amused, since the whole story seems to be a marketing stunt for his books.

    I love the story thought. It’s like a good novel by Umberto Eco.

    I’m member of Bruno forum at FB, and one member, who I’m in contact with, said, that Brunos father dropped a message that they will publish the first book by Bruno as ebook. And members of that forum will be the first to achive it. The book is in Portuguese though.

    In this first book Bruno writes about his ways to achieve as many knowledge as possible.

    Passo agora uma sinopse desse magnifico autor, analisado por nosso consultor Carlos.
    O Primeiro livro de Bruno Borges propõe uma metodologia capaz de potencializar a absorção e a criação de conhecimentos. O autor propõe uma série de práticas e mecanismos que podem levar o indivíduo a multiplicar seus conhecimentos.
    A Teoria da Absorção de Conhecimentos (TAC) parte de uma visão dialética clássica, porém, propõe uma metodologia completamente inovadora na forma de explicá-la.
    Dentro das práticas propostas por Bruno Borges está o isolamento, que, segundo o autor, pode potencializar a espiritualidade e os órgãos sensoriais para gerar “insights” produtores de novos conhecimentos.
    Bruno vem testando em si mesmo a sua teoria, demostrando na prática que, com a produção de 14 livros em um curto período de tempo, foi possível potencializar seu cérebro de uma forma não explicada pelos métodos de aprendizagem convencionais.
    Segundo Bruno, a obra é uma ação que gera a reação do isolamento, a paixão é uma emoção que gera a ação de criar, e unidas à fé, geram um estado de espírito capaz de transforma o ser humano e agigantar seu potencial criador

    ist schon jemanden aufgefallenwie das erste bild angeordnet ist?
    fällt schnell auf das jeder buchstabe seinen platz hat. ich bezweifle das er zu faul war die bleistoftmakierungen zu entfernen.
    viel mehr glaube ich man braucht eine art schablone die man darüber legt.
    darauf verweisen auch die 2 schwarzen punkte die als anlegemakierung dienen könnten.
    könnte sein das es sich bei der schablone um den schlüssel handelt und das alphabet nur eine ablenkung ist.

    bruno borges ist wieder da!
    am 11.08 tauchte er vor der wohnung seiner eltern auf und wurde von einer sicherheitskamera gefilmt.
    er gab einer portogisischen zeitung ein interview:

    aus dem bericht geht auch hervor das die polizei bei einem studienfreund verträge fand, die ihn an den verkäufen der bücher begünstigen.
    außerdem fand man bei dem studienfreund auch möbel aus seinem zimmer. bruno hatte also hilfe und das ganze war von vornherein als marketingstrategie geplant…
