    About Me

    I don’t just defend systems, I outsmart attackers before they even knock. Sharp, surgical, and paranoid enough to automate my phone to kill Wi-Fi the second I leave home. So if you thought you could be my evil twin, you’ll need to target someone else

    Where I come from

    I am Claudio Marongiu, a guy living on the lookout for what others haven’t even spotted yet.

    I started building networks at 9. It took me a week to figure out why my cascaded router wouldn’t always "connect to the internet". Turns out, it was assigning IPs "just sometimes". Why? Because DHCP was on. Why didn’t I just look it up? There was nowhere to look that up on. The internet wasn’t really a thing yet. Yes, I’m that old

    Over time, I built my own digital space, my own servers, my own rules. But that wasn’t enough. I needed to learn how to defend it. So I did it my way. Later on I first graduated in Communication Science to master how to spot social engineering attacks, then in Computing Science to get hands-on with what I truly love.
    This is my world.
    Welcome!
