Part 4 — Agent Risks, Disinformation, and Systemic Impact

Overview

Capability and risk are not separable. Every property that makes an agent useful — autonomous action, broad tool access, persistent operation, the ability to communicate fluently — also creates a surface for failure, exploitation, and harm.

Part 4 examines the risk landscape of agentic AI from three perspectives: the intrinsic limitations of agents as reasoning systems, the deliberate attacks that adversaries mount against them, and the systemic effects that emerge when agents operate at scale inside information environments. None of these risks is hypothetical. Each has already materialised in early deployments, and each will become more consequential as agent autonomy increases.

The chapters in this part are not cautionary tales meant to discourage deployment. They are an honest account of the failure modes that practitioners need to understand before they can design around them. An organisation that has read these chapters is better positioned to deploy agents safely than one that has not — not because deployment becomes easier, but because the risks become legible.

Chapter 12 examines the intrinsic fallibility of agents — where perception gaps, misclassification, and reasoning errors originate, and how they manifest in production. Chapter 13 maps the attack surfaces that agentic architectures introduce, with particular attention to prompt injection, tool abuse, and cross-agent trust exploitation. Chapter 14 examines the disinformation dimension: what happens when agents capable of generating and distributing content at machine speed are deployed without adequate controls on what they produce and amplify.
