WHAT YOU WALK OUT WITH
🏴 The "Ghost" badge top 3 teams only. Permanent rank boost on the Cyber Unbound platform, visible where recruiters look. Never issued again after this event.
📜 Signed certificates from Zeron and Cyber Unbound for all 10 finalist teams.
🛰️ A hardware bounty on one challenge. First team to crack it takes the device home. We're not saying what it is only that it's on most hackers' wish lists and does something you shouldn't be able to do from a laptop.
🎁 Plus a few prizes we're not announcing. Physical. Collectible.
🍕 Food and non-alcoholic drinks all day, on us.
