GenAI agents are currently navigating a perilous "Perfect Storm" defined by the dangerous intersection of three key vulnerabilities: access to sensitive data, exposure to untrusted content, and the capability to execute external commands. This technical deep dive will unveil the architectural principles and defense strategies utilized to protect Gemini and the Google Workspace ecosystem from this toxic convergence. Moving beyond mere hypothetical discussions, this session provides a detailed breakdown of real-world attacks, specifically, a vulnerability where an attacker could hijack an agent simply through a calendar invitation. Attendees will acquire practical insights into Google’s rigorous defense-in-depth blueprint, covering advanced prompt injection defenses, strategic chaining policies for sandboxing rogue agent actions, and thorough sanitization techniques for hazardous outputs.
