Hacking Week 2015

The Hacking week just started, it’s a CTF that happens over a week.

You’ll find challenges about crypto, network, forensic, reverse and exploit.

And also, I have a challenge up there in the crypto challenge ^^

It’s in french here: http://hackingweek.fr/challenges/ (click on “voir” next to crypto 4)

basically Alice encrypted the secret, you have to find what the secret is. What you have is a key that shares the same modulus as Alice.
