We are pleased to announce the program of GreHack'18. A more precise schedule will be published in a few days.

As many of you seem stuck on the "Network" challenge, here is a hint: The challenge is not steganography, is offline and is self-contained. Have fun!

GreHack challenge is online! You can participate through this link: https://2018.challenge.grehack.fr/. There are free tickets for GreHack 2018, and sweet sweats (sic) offered to the first 3 persons who manage to solve the challenge! Good Luck and Have Fun!

The 6^th edition of GreHack will hold on November 16^th, 2018 in Grenoble, France.

GreHack 2018 is thankful to the following entities to help us make this event live another year.
