AI Security 2025: Promptware, Indirect Prompt Injection & the First “AI Worms” (with a Python Mitigation Kit)

I broke a Python AI agent with prompt injection, then hardened it until the attack failed. In this article, you’ll get the exact AI security playbook, production-ready middleware, a pytest red-team harness, and a copy-paste policy that blocks indirect prompt injection and early-stage AI worms.

This article provides a comprehensive examination of AI security risks, focusing on prompt injection as a critical threat. It details the various types of prompt injection, particularly highlighting the dangers of indirect prompt injection and self-replicating AI worms. The author shares a practical Python mitigation kit designed to enhance security against these threats, including strategies for sanitizing input, restricting tool usage, and implementing robust content policies. The goal is to educate developers on how to create safe AI agents that effectively mitigate the risks posed by malicious input.
