3 challenges from h0h0h0day

The next edition of Montrehack will be held on Wednesday February 22nd 2023.

For this MontréHack, we’ll review three challenges from our last h0h0h0day CTF!

1. Behaviors we love! (by Fob, category shellcoding/pwn)

   Santa wants to know if you’ve been naughty or nice. Can you put yourself on the nice list to get your gift?

2. Blackmail (by KptCheeseWhiz, category forensics)

   I managed to clone Santa’s USB key which contains all his darkest secrets. I could use it to blackmail him to finally get out of the naughty list, but it is encrypted with something called BitLocker, can you help me open it? I have the recovery key file, but it is corrupted and unreadable, maybe you will be able to do something with it?

3. Fête de l’hiver (by Klammydia and privat, category pwn)

   Vous êtes invités à la grande fête de l’hiver.
