Old Memories

Welcome to GreHack 2016 challenge. This challenge is composed by several steps. You need to validate step { n } to access step { n + 1 }.

You can see the progression of pwners in the scoreboard. The first three to complete the challenge will be offered a ticket for GreHack 2016 and a sweet sweat (sic) - Edition GreHack 2016 (this one), and one of them will present (a part of) his solution during the conference. The first pwner to complete the challenge will have a Benefactor ticket, which includes diner with speakers the day before (November 17th). You can play in teams but only one person will receive the prize.

For any question, you can contact us on twitter at @GrehackConf (#OldMemories), by mail at challenge@grehack.fr or on irc at securimag.org, channel #OldMemories.
