Explore the security implications of the emerging Agentic Web in this 58-minute conference talk that examines how AI agents are transforming digital creation, interaction, and consumption. Delve into the risks of an internet increasingly mediated by machines rather than humans, and understand how large language models are reshaping online information consumption and everyday tasks including shopping, employment, and relationships. Learn about the emerging threat of bot-versus-bot warfare where malicious agents exploit human agents, and discover new vulnerabilities through the lens of cognitive security. Analyze real-world examples of agent exploitation and examine scenarios depicting near-future risks driven by economic pressures and rapid AI adoption, while gaining insights into how to navigate this evolving digital landscape where human attack surfaces are being redefined by artificial intelligence.
