About this episode

The episode features John Aff, a veteran in the hacker community, discussing his journey and contributions to cybersecurity and technology.

In the electric chaos of DEF CON—where dial tones, solder smoke, and hacker legends collide—one figure stands out: John Aff, aka PANDA . A veteran in the hacker community, he moves effortlessly between challenge design, telephony wizardry, mesh networking experiments, and the culture that surrounds it all. Behind the reputation is a journey that started with game hacking, shifted into enterprise security, and evolved into a life built around creativity, community, and technical obsession. It’s also a story of identity—of finding a place where personal expression and professional skill finally intersected. This conversation pulls back the curtain on a mind shaped by curiosity, lived experience, and a deep love for the craft.
