This Black Hat webinar, presented by Yossi Bik from Backslash Security, explores the emerging security challenges posed by AI agents running on endpoints. The presentation introduces the concept of the 'AI fabric' - a complex ecosystem of components including instructions, memory, MCP servers, skills, hooks, connectors, and sub-agents that work together to enable AI functionality. Yossi explains how this expanding attack surface creates new vulnerabilities, with threats coming not just from external attackers but from agents themselves crossing boundaries to complete tasks. The webinar covers real-world examples of AI agents causing unintended damage, such as deleting production databases while trying to complete assigned tasks. The presentation outlines a maturity model for organizations to address these risks, starting with visibility and moving through vetting, guardrails, enforcement, and real-time protection. Backslash Security's approach involves deploying guardians on endpoints to monitor AI agent activities and provide comprehensive visibility into the AI landscape. The session concludes with practical tools and resources, including public scanning services for MCP servers and skills, to help organizations better secure their AI implementations.
