Friend or Foe? AI at Play in Cybersecurity

AI is a double-edged sword in cybersecurity. This talk explores its dual role.
Why AI excels: Vast open-source training data and profit-driven, coding-optimized models make AI a fast, multi-domain expert at writing and finding vulnerabilities in code.
Gatekeeping: Projects like Claude Mythos and Project Glasswing raise hard questions about who should access these powerful tools.
The asymmetry: AI is fundamentally reshaping the defense/offense balance—and demands responsible deployment.


Artificial intelligence (AI) has rapidly become a major force in the technology landscape, raising the critical question for security professionals: Is AI a friend or a foe in cybersecurity?

This talk will explore AI's dual role, starting with its proven excellence in coding, fueled by extensive open-source training data and models tailored for efficient, profitable business use cases. We will then examine AI's powerful capability to find code vulnerabilities at high speed, acting as an expert across multiple technical fields simultaneously.

The presentation will shift to the crucial topic of "gatekeeping" these advanced cybersecurity tools, discussing projects like Claude Mythos and Project Glasswing, and addressing the complex question of who should have access.

Finally, we will analyze the evolving asymmetry in cybersecurity—the balance between defense and offense—and how AI is fundamentally changing the game. Ultimately, AI is a double-edged sword that demands careful handling and responsible deployment.
