Hello

Some might wonder who I am, does it really matter? I could be your neighbor, your kids’ friend, or your friends’ friend or boyfriend or girlfriend, or I could be your son or daughter.

That being said, the reason why I’m here is to share my knowledge in the field of breaking security defenses.

It will contain write ups from ctf’s, wargames, etc, and disclosures when I have some.

I guess that’s it for the introduction.
