La Quête du sens
For this challenge, we are given this audio. We need to find the name of the text that this song comes from. We know that the name of the woman we are searching starts with Mar… Marie ? Margarette ? Marion ? Who knows ?
This took a while to get done. I first try Deezer or similar tools to find the music without success. I then tried to Google poetesse morte francaise because this hole CTF is about French literature and found two results that could be the good ones:
But Marguerite Yourcenar was Belgian-born, so I tried the other one Marceline Desbordes-Valmore. On her Wikipedia page, we can see a list of her poem that was set to music. The tune of the music didn’t seem really classic, so i tried from the end of the list until I get into the music of Julien Clerc called Les Séparés. It is said that Julien Clerc a ainsi mis en musique le poème « Les séparés », qui avait déjà été mis en musique par Henri Woollett, chanson intitulée Les Séparés dans l'album Julien, 1997 ;. So I search the music on YouTube and at this time watch of the music we hear the same tune of the piano that we had.
The flag is then obviously: 404CTF{les_séparés}
