From October 8th to October 24th took place the online qualification round for the European Cyber Week CTF Finals, that are held every year in Rennes, France.

I had the opportunity to create a challenge for this event as part of my internship at Thalium. This was the first time I actually publish a challenge and I hope those who gave it a try enjoyed it.

On June 27th 2020, I participated in the finals of the French Cyber Security Challenge, a capture the flag brought by the ANSSI (France’s National Cybersecurity Agency).
