48 Hours: Anatomy of a Real Cyberattack

📋 Overview

This narrative-driven session provides a minute-by-minute deconstruction of a realistic cyberattack, modeled on actual events. Participants follow the progression of a breach from the initial phishing email on a Monday morning to the final ransom demand on Wednesday night. By examining the attack simultaneously through the eyes of the victim, the attacker, and the incident responder, the course clarifies how technical decisions and human errors intersect to create a crisis. The presentation avoids blame and instead focuses on the technical annotations of the attacker's moves and the first 48 hours of recovery efforts. The session concludes with a postmortem analysis of the specific controls that could have prevented the breach and a defense framework built directly from the narrative events.
