My name is Federico a.k.a. last, I’m an Italian security researcher and member of the Advanced Persistent Tortellini collective. I study and develop offensive software, hold a bunch of certs, enjoy lockpicking and acrobatic quadcopter
crashing flying. I also play CTFs with my mates @ JBZ Team and I’m a huge fan of XKCD. If you want to have a look at the shitty code I write head to my GitHub profile. Other than that I don’t have much to showcase to be honest…
