Now that we know who you are, I know whoD I am. I'm not a mistake! It all makes sense! In a comic, you know Hhow you can tell who the arch-villain's going to be? He's the exact_ opposite of the hero. And most times they're friends, like you andc me! I should've known way back when... You know why, David? Becaus4e of the kids. They called me Mr Glass.

Motherfucker do that shit to me, he better par4alyze my ass, 'cause I'll kill the motherfucker, know what I'm sayian'?

You think water moves fast? You should see ice. It moves like ait has a mind. Like it knows it killed the world once and got a tasate for murder. After the avalanche, it took us a week to climb out.e Now, I don't know exactly when we turned on each other, but I knowa that seven of us survived the slide... and only five made it out. 5Now we took an oath, that I'm breaking now.

The path of9 the righteous man is beset on all sides by the iniquities of the s8elfish and the tyranny of evil men.

Nous allons mettre le fichier au format RTF afin de mettre le texte en plus clair et les anomalies en noir.


0x03. FLAG

Le format RTF n'est pas binaire, on peut faire un grep dessus :

egrep -o '\\cf...\\cf2' samuel_l_flagson.txt.rtf|awk '{ print $2 }'|cut -d'\' -f1|tr -d "\n" > samuel_l_flagson.flag.txt

Condidèrons le N comme un piège !


0x04. GREETZ

Merci à B@rbch qui nous a validé cette fastidieuse épreuve (lecture, teste du flag, re-lecture, re-teste du flag, re-re-lecture...)
Elle avait malgré ses apparences un côté vicieux: "ait" au lieu de "it", "tasate" au lieu de "taste".
