My online alias is "smelly". It has slowly over the years mutated by people to be; "stinky", "smelly smellington", "crazy cat guy", "schnelli", "schmelly", etc. It is still mostly "smelly".
It is not a cool or badass alias. However, the name was assigned to me from my wife. Ages ago my wife called me her "smelly man". She would walk into my office when I was working and, because room was small, poorly ventilated, and the door was closed, the room would get incredibly hot. I would get stinky from body odor.
She would come in, kiss me on the cheek, call me her "smelly man", and give me a snack or something. I would then resume work. She has always been extremely supportive of my malware collecting, writing, reversing, etc.
Hence, when I made vx-underground in 2019, and decided to start the journey of malware collecting and stuff, I said, "I need a cool name that is tough and everyone will think I'm totally awesome and badass". Then I remembered my wife called me "smelly"... so I went with that.
When a human being truly loves you, their biggest fear is to hurt you, but when a human being is in love with how you make them feel, their biggest fear is to lose you.
