Maintenant que la compréhension du programme est vue, il est possible de développer un générateur de licences en Python. La contrainte principale est d’interagir exclusivement avec le conteneur Docker via le port réseau exposé, toute autre méthode n’étant pas considérée comme une solution valide. Ainsi, le script doit être conçu pour communiquer avec le conteneur à l’aide de netcat sur le port 4000. Chaque fois que le programme du conteneur demande une licence, le script devra lui envoyer automatiquement une réponse appropriée via netcat. Le script fait ainsi tout le travail.

On voit qu’il y a 50 demandes de licences, et, surprise, 2 flags :
-
un flag pour “the Junior Challenge”, qui se répète tout le temps :
FCSC{2053bb69dff8cf975c1a3e3b803b05e5cc68933923aabdd6179eace1ece0c41a} -
un flag pour “the Pinkman Challenge”, qui consistait donc à répondre correctement à toutes les demandes :
FCSC{9600becd765ca03baa623504244e008e6f3348bce0219fe4027432d790dd074f}
Maintenant que le challenge est résolu, si on regarde dans le container :
