About

Both Sides of the Prompt

Same models. Different targets. Parham and KC split the talk across the line — offense and defense, using the same AI tools most of the room already uses every day.

Parham on offense. Driving AI agents (Claude Code, Codex, local LLMs — BYO) against Prior Art: a reproducible pentest home lab being open-sourced the night of the talk. Every technique is already public — that's the name. The lab gives AI agents a stage to execute end-to-end, so you can see where they actually succeed, where they stall, and what the attack surface looks like when the attacker is a model.

KC on defense. Detection and response against AI-driven attackers. What signals change when the operator is an agent, and what stays the same.

Think of this as a direct answer to Jeet's March talk ("LLMs Don't Hack, They Guess") — a lab-centric counterpoint that lets you judge for yourself.
