Security researchers warn that the next major breach involving agentic AI systems may not originate from vulnerabilities within the AI models themselves, but rather through compromised API pathways that these systems use to interact with external services. The article suggests that organizations deploying agentic AI should prioritize securing the integration points and API connections that autonomous agents rely upon, as these interfaces may present overlooked attack vectors. This represents a shift in security considerations as enterprises move beyond model-level threats to address infrastructure-level vulnerabilities.
