The Hidden Attack Surface in Agentic AI Workflows

This is a placeholder post. Replace this content with your actual writing.

The problem

When AI agents can execute multi-step workflows autonomously, every tool integration becomes an attack surface. Most security models assume a human in the loop. Remove the human, and the threat model changes fundamentally.

What I’m seeing

At Hiro, we think about trust boundaries constantly. Building infrastructure for a blockchain means every design decision carries real financial consequences. The same rigor needs to apply to agentic systems.

More to come on this topic as I develop the thesis further.
