Starting from 2019, we will invite Swiss and French technical school teams to participate in the onsite CTF. They will have a specific ranking in order to compete against each others. We will also have prizes for the winners. Please contact ctf [at] for more details.

Our GitHub repository is here, where challenges solution and source code for past editions can be found. There are also links to solutions on CTFTime.

CTF Prizes

As cryptocurrencies can't be trusted, we provide real, old-fashioned silver for the top 3 teams

The first 3 teams of the school ranking will receive prices and swag sponsored by QoQa.

Boss Of The SoC

This year again, we'll be hosting the Splunk Boss of The SOC (BOTS) contest during Insomni'hack, on the Thursday 21st afternoon from 15h30 until 19h00.

BOTS is a blue-team CTF where participants use Splunk — and other tools — to answer a variety of questions about security incidents that have occurred in a realistic but fictitious enterprise environment. It's designed to emulate how real security incidents look like and the type of questions analysts have to answer. You’ll be endorsing the role of an incident responder, facing down an adversary at all stages of an attack.

The event will take place on the 21st of March and will last for 3 to 4 hours. You will play in a team of 1-4 people and compete against other participants. Each team is presented with a list of questions of varying difficulty through an automated BOTS scoring server. Each correct answer will be rewarded with an amount of points proportional to the question's difficulty. All questions require you to use Splunk to search, but not all questions can be answered without the help of other open source intelligence resources. Just like in the real world.

So what's next?

You don’t know Splunk yet? No problem! Check out our "Hunting with Splunk: The Basics", which has been created specifically to prepare teams for what they will face in BOTS.

The event is open to everyone, but you must register to participate : Please note that registration for the BOTS does not grant entry for the conferences, only for the BOTS contest.
