AI Agent-to-Agent Communication: The Next Major Attack Surface
We are witnessing the end of the "Human-in-the-Loop" era and the beginning of the "Agent-to-Agent" economy. Until recently, most AI interactions were hub-and-spoke models where a human user prompted a central model, reviewed the output, and then took action. That model provided a natural safety brake. If the AI hallucinated or suggested a malicious action, a human was there to catch it. That safety brake is disappearing.
