CTF CryptAbyss

Mon, 01 Jan 0001 00:00:00 +0000

Since last year, my university has orchestrated a yearly Capture-the-Flag, and this time, I am one of the organizers of the event.

In a CTF, we simulate a voluntarily vulnerable network that we may find in a company or at home.
The players will have to search and go as deep as possible to find pieces of texts called flags, that all give points. The team with the most points at the end win.

Marathon Detection

Mon, 01 Jan 0001 00:00:00 +0000

At university, we were given a project: detect players of a marathon at checkpoints with a camera from only their BIB numbers.

Online, almost nothing existed; only one found had small dataset of ~100 images.

We used a normal YOLO to detect people and easyocr to detect text written on them, we created a dataset from YouTube video (~10'000 images after some cleaning)

From this dataset we trained a new specialised YOLO in bib number detection thanks to our university AI server, combined with paddleocr to read poor quality text.

University AI Server

In my final year at university, we received some servers, but one was special: it contained an NVIDIA RTX 6000 ADA, a name that would make any gamer have a heart attack if they learned its power (and its price).

This was a special card made for huge calculations and artificial intelligence: thanks to its 40GB of VRAM, it could handle a huge model, from a simple large language model to video generation.

University Servers

This year, a company upgraded their server and gave the old ones to our university, which ended up being used by our classes to train on networking and on services deployment.

We thought about how we could connect them. One was going to be our main docker server to install service such as an LDAP server, a Nextcloud, a Forgejo, a Matrix server, a Nginx to link everything and some other niche service such as a Satisfactory and Minecraft server.
