Ringzer0 COUNTERMEASURE

COUNTERMEASURE is a curated gathering of internationally recognized cybersecurity researchers, instructors, and leaders from around the world. Designed for professionals across government, critical infrastructure, industry, and academia, we showcase the research, intelligence, and tradecraft shaping modern cybersecurity. Each Spring we deliver immersive virtual training led by globally respected experts. Each Fall we bring the international cybersecurity community to Ottawa, Canada for world-class hands-on training and a limited-capacity, single-track conference featuring original research, strategic insight, and direct access to internationally recognized speakers and instructors.

All Trainings for FALL//2026

Fall 2026 Inperson Training

Windows Enterprise Incident Response: A MITRE ATT&CK & Unified Kill Chain Approach

Learn DFIR investigative tradecraft for Windows enterprise intrusions using two open frameworks: Unified Kill Chain for the full attack narrative and MITRE ATT&CK for evidence-backed TTPs. Practice backward/forward scoping from triaged host to enterprise threat hunting; methods transfer.

Fall 2026 Inperson Training

Practical Threat Hunting

Learn practical cyber threat intelligence, build a repeatable hunt methodology, hunt with endpoint data, and measure effectiveness. Hands-on labs develop hypotheses across social engineering, network/system compromise, and APT scenarios using CLI, Jupyter, and Velociraptor.

Fall 2026 Inperson Training

Windows Kernel Exploitation

3-day lab-driven course on Windows kernel internals, memory management, and privilege escalation. Explore real-world vulnerabilities, exploitability analysis, data-only attacks, and modern mitigations to understand how Windows security boundaries break and how to defend them.

Fall 2026 Inperson Training

Practical Web Application Penetration Testing: From Fundamentals to Exploitation

Hands-on web app pentesting course for security analysts moving into offensive security. Learn to find and exploit common vulnerabilities in modern web apps and APIs through guided labs, using industry tools, open-source frameworks, and LLM-assisted testing workflows.
