Podcast Notes


  • Zapp
    • Chief Bling Officer (CBO) at AND!XOR
    • During his limited free time he writes vulnerable C code, dabbles in Kicad, and trolls Arduino bot accounts on Twitter
    • Never been seen at the same time and place as Batman…But then again, neither has Stephen
  • Hyr0n
    • A button pusher, easily replaced by a thousand monkeys with a thousand laptops, but manages to crank out firmware and hacker puzzles
    • If you’re reading this statement, he already has root access to your computer

We have had Zapp and Hyr0n on the podcast before. Check out MEP EP#69: Incognito Mode and MEP EP#109 Arduino, The Gateway Drug To #BadgeLife.
