Alexander Wilczek

Hey I'm Alex, a digital nomad fighting cybercrime. I've been travelling Australia (and the world) full time for over three years in my Landcruiser and hacking the planet from the most pristine beaches to the most remote parts of the outback. I specialise in dark web, cybercrime and blockchain security. I'm also the proud founder of Rivanorth.
