Your AI agent can be compromised without a cracked password or a line of malware. One hidden sentence in a document it reads is enough, because to a language model, data and instructions are the same stream. The whole book runs on one idea: an attacker only has to win one of three. You have to hold all three.
Written for: engineers and red-teamers wiring up agents and MCP servers, and the leaders and CISOs who fund and answer for them.
