Conférence francophone sur le thème de la sécurité de l'information.
Elle se déroulera à Rennes du 5 au 7 juin 2024.

Challenge 2024

Description

The year is 2022. Gunshots shattered the night. A witness caught a glimpse of a vehicle at the scene — a Tesla, they claim? The investigators on the case firmly believe this incident is affiliated with a clandestine criminal group that has eluded them for years... You are given the police reports and a backup of the car's logs. Your technical expertise is needed to move the investigation forward!

Your are mandated to conduct an investigation on this group and ultimately retrieve a validation e-mail ([0-9a-f]{16}@sstic.org).

Once you have found this address, in order to confirm that you solved the challenge, you must:

Intermediate flags (SSTIC\{[0-9a-f]{64}\}) can be found after solving each chapter (step). You may submit them on this page if you're logged in, although this is not a requirement for entering the final leaderboards.

Important advice regarding the prologue: don't overthink it! Just carefully read the elements you are given — these clearly suggest what you should look for in the context of the investigation. As mentioned right above, an intermediate flag can be found after you solved the prologue; you are not necessarily looking for a SSTIC-formatted flag right away. Immerse yourself and try to answer what you're asked!

Prizes

There are two distinct leaderboards: speed and quality. The speed rankings will be updated over time as we receive validation e-mails.

The quality leaderboard will reward the most detailed, elegant and best-written solutions. Therefore, even if you are not among the fastest finishers, you can still aim to win a prize by writing a high quality report. The winner of the quality category will also be offered the opportunity to give a talk about the challenge solution during the SSTIC conference.

The top three of each leaderboard will win the following prizes:

Please note that in order to be eligible in the speed category, you must still provide a write-up for the challenge, even if you do not wish to take part in the quality category.
