Thinking Like an Attacker Is No Longer Optional

Introduction: The Necessity of an Adversarial Mindset

Moderated by Abhijith 'Abx' B R (founder of Adversary Village) alongside Keenan Skelly, this expert panel features Bryson Bort (founder of SCYTHE and GRIMM, co-founder of the ICS Village), Anant Shrivastava (founder of Cyfinoid Research), and Lieutenant Colonel Gordon Baum ("Fizzle", US Air Force 567th Cyberspace Operations Group). The panel addresses why passive, compliance-driven defenses inevitably fail against modern threat actors and makes the case for systematically embedding offensive adversarial thinking across organizational security programs.

Distinguishing the Hacker Mindset from the Adversary Mindset

The panel delineates the crucial differences between a generic hacker mindset and a strategic adversary mindset:

Hacker Mindset: Characterized by intellectual curiosity, technical exploration, and exploiting technical quirks in isolation.

Adversary Mindset: Driven by strategic mission objectives, economics, planning, and persistence. Real-world adversaries are not lone hobbyists operating in a vacuum; they operate with defined mission parameters, budgets, timelines, and logistical constraints. Adversaries prioritize the path of least resistance—whether through physical close-access operations, social engineering, or abusing misconfigured trust relationships—rather than exclusively pursuing complex zero-day exploits.

The Evolution of Offensive Security and Moving Beyond Ego

Bryson Bort highlights how offensive security has matured over the last decade. Historically, penetration testing and red teaming were frequently dominated by adversarial ego, where operators sought to breach Domain Admin, drop a brief technical report, and move on without providing actionable remediation guidance. Modern offensive security must focus on partnership with defenders, measuring success by how effectively the engagement improves detection visibility and defensive resilience.

Breach and Attack Simulation vs. Critical Thinking

The panel evaluates automated Breach and Attack Simulation (BAS) platforms versus human-led adversarial testing. While automated BAS platforms provide consistent regression testing and baseline telemetry, tools cannot replace human critical thinking, contextual analysis, and creative pivoting. Tools exist to support organizational processes, governance, and people—not to replace strategic judgment.

Prioritizing Defense: From Vulnerability Assessment to Red Teaming

Anant Shrivastava and Gordon Baum discuss the practical stages of building an offensive-informed defensive posture:

Foundational Hygiene First: Organizations must establish basic asset inventory and vulnerability management before rushing into complex simulation exercises. Handing an immature team a list of thousands of simulated attack findings creates paralysis.

Graduated Progression: Organizations should progress systematically from vulnerability scanning and penetration testing to purple teaming, and ultimately to full-scope red teaming.

Contrarian Perspective: Adversarial thinkers introduce contrarian viewpoints, challenging organizational assumptions regarding which assets are critical and how trust boundaries interact.

The Role of Open-Source Tools and Practical Purple Teaming

Defenders do not require multimillion-dollar budgets to adopt offensive thinking. Free and open-source tools—such as Atomic Red Team or PowerShell-based execution scripts—allow blue teams to generate reliable adversarial signals and test log ingestion pipelines immediately. Collaborative purple teaming aligns teams across scoping, execution, and validation.

Key Takeaways for Modern Defenders

Security is a Critical Thinking Discipline: No tool or AI platform can replace contextual human analysis and threat understanding.

Adopt Adversary Economics: Understand what threat actors want and how they calculate risk, cost, and opportunity when targeting your environment.

Collaborate Continuously: Bridge the divide between offensive researchers and frontline defenders to turn vulnerability discovery into long-term defensive resilience.
