Welcome to Intrusion Chronicles

Intrusion Chronicles is ISAUnited’s Red Team intelligence publication, built to help defenders think like adversaries without teaching misuse. We study real world intrusions and translate them into clear exposure conditions, attack progression, and defensible engineering actions that security leaders can apply.

Our Red Team intelligence is organized as structured, scenario driven insight. We frame adversary operations using the Threat Operations Functions phases, then connect what we learn to what must be engineered and defended across the Defensible 10 Standards domains. The result is practical intelligence that supports architecture decisions, monitoring priorities, and proof of readiness.

This publication exists for authorized education, simulation, and professional awareness. We do not provide step by step intrusion instructions. We focus on what matters most: what failed, what enabled compromise, what should be designed differently, and what evidence a mature security program must be able to demonstrate.

If you are a security architect, engineer, practitioner, or technical leader, you are in the right place. Welcome to Intrusion Chronicles.
