3 - Zombies like PPTP
Our intel shows us that the Zombies use a MS-PPTP like protocol and luckily we
could intercept a challenge-response transmission of one of the Zombie
outposts. The important thing for Zombies in this war is mass! Not only brain
mass but their mass. So they built their PPTP protocol compatible to all older
Zombie soldiers. Luckily our science team could extract the algorithm of the
challenge-response system out of a captured Zombie brain … I spare you the
details, let's just say it was not a pretty sight. And here comes your part
soldier: we need the password of this intercepted transmission. With this
password we were finally able to turn this war to our favor. So move your ass
soldier and good luck! https://ctf.fluxfingers.net/challenges/pptp.tar.gz
