Researcher reputation:  10

Real name:
Leonardo Porpora

About me:
I'm student at the Liceo Redi in Arezzo, I do really like cyber security since I was 15 and I'm working hard every day to make my knowledges better and better. I do research and pentesting, and nowadays these are the things that I like most. When I break into systems I get so excited, I think that beeing an Ethical Hacker is a great way to help people because it's a way to improve the security and prevent cyber criminals to have unathourized access. I'm a member of Nint.en.do hacker group.

How to contact me:
You can contact me by e-mail [email protected] or better through Signal (39) 3453289898

Experience in Application Security
1-3 years

Award / Bug Bounty I prefer:
Being a researcher is good way to help people that can't afford a PT, if you feel like giving me something more for the time I spent trying helping you, you could send me Bitcoins, Swag stuff :)
