These competitions are designed to educate and inspire high school students through interactive hacking challenges. This ctf had some very interesting challenges and also very difficult ones, in the end we scored 26 points in the global ranking and we placed second in the national one.

6th Place at TUCTF 2019

TUCTF was our first event with a weight on CTFtime.org and after completing all of the challanges within the 3 days that the event lasted we are very proud of our result and of the points it brought to us on the official ranking. This CTF improved us as a team in many ways and it was not easy to complete all the challanges in such short time but now we look forward to the next event, hoping to add some more points to our ranking.

7th Place at Cryptowars 2019

The crypto group (CLUB) of the System Security and Cryptography Lab, at Università degli Studi di Milano, in collaboration with De Componendis Cifris (Associazione italiana di Crittografia) and Clusit (The Italian Association for Computer Security), organized the "Cryptowars 2019". This contest aims to raise awareness of the fact that cryptographic algorithms get old and they should be continuously tested, maintained, improved. The event was a week long (21/10 - 27/10) and it had 30 challenges, at the end of the contest we managed to complete 8. We are proud of the result and most importantly this challenge raised our knowledge and awareness on many aspects of cryptography which is going to be very useful for our next CTFs.
