Why it matters
Prompt injection remains an unsolved structural weakness in LLM-based systems, and defenders building AI agents need a clear mental model of attack vectors and mitigation layers.
This article is an explainer on prompt injection attacks against LLMs, covering direct versus indirect injection, the distinction from jailbreaking, and defensive practices such as least privilege, treating external content as untrusted, breaking the 'lethal trifecta,' human approval for high-risk actions, and adversarial testing. It references OWASP's Top 10 for LLM Applications and uses a hypothetical example to illustrate the risk.
