The Operator

The Operator is the offensive security practitioner behind Krypteia Sec. Two decades in red teaming, now focused entirely on the agentic era: testing the LLMs, AI agents, MCP servers, and RAG systems that organizations are shipping faster than they can secure them.

The same operator designs the autonomous hackbots, runs the engagements, and writes every brief published here. The work spans prompt injection and jailbreaking, MCP and tool-layer security, agent kill chains, and the detection engineering that catches them.

Krypteia keeps the old tradition: the ancient krypteia operated unseen, testing defenses from the shadows. No names, no titles, just the work and the results it produces. To date that work includes 117 daily intelligence briefs, published every morning by an autonomous pipeline.
