Contest – Tamper Evident Contest

Break in and leave no trace behind…

Welcome to this year’s Tamper Evident Challenge!

This year, the F.I.B agency is back again and needs your help breaking into a package to swap some items. The challenge will be split into two sections: Beginner and Advanced.

For the beginner’s challenge, you will be tasked with lifting various seals and stickers without leaving residue behind. There is no time limit, but how fast you complete the challenge will affect your score. This is a solo challenge, but verbal communication with other participants is allowed.

For the advanced challenge, you will be tasked with breaking into a multi-layer nesting doll package and swamping objects in the middle. This challenge is completed onsite, and all necessary tools are provided. You will have 30 minutes to complete the challenge; speed will factor into your score. This is a team challenge, but teams will be limited to two people.

Where Is It

Find us next to the AppSec Community. You can’t miss the carnival themed games.

How to Play

You’ll play the games right at our booth, using a provided laptop.

Each game may look simple on the surface, but hidden within each game is a subtle vulnerability. Exploit it to win big.

What to Bring

Just yourself! The booth setup includes everything you need to play.

For more points you’ll want to submit a fix, and you’ll need a device to code that up.

Important Times

The AppSec Carnival runs from Tuesday afternoon to Friday morning.

Each game may look simple on the surface, but hidden within each game is a subtle vulnerability. Your mission: exploit it to win big.

You’ll play right at the booth, using a provided laptop. The source code for each game is open and available on GitHub, so your only real enemy is your own curiosity, skill, and time. Get lucky or clever and you might walk away with a few points and a trinket. But if you dig deeper and find the exploit? That’s where the real points are.

Once you’ve broken the game, you’ll also get the chance to submit a fix through our testing harness for even more points. Your exploits and fixes will earn you a spot on the leaderboard—and the top three contestants will win actual prizes.

How to Play Our Contest

You’ll need a ticket to play. These may be handed out during the con or earned by engaging with various other SAINTCON communities.

Redeem your ticket at the booth to take a crack at a game.

You can return and play again if you earn more tickets—each game is standalone and has its own challenge.

Notes

This contest is designed to be fun, welcoming, and hands-on—no gatekeeping here. Whether you’re a first-time player or a seasoned security pro, there’s a game (and probably a janky plush prize) with your name on it.

Come try your luck. Cheat the system. And leave it better than you found it.
