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

Starting from 2018, Insomni'hack also host the Splunk Boss of The SOC (BOTS) contest, usually on the Thursday 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 takes place on the Thursday and 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?
