Prompt Injection Attacks: The Top Security Threat Hijacking AI Chatbots

Summary

Prompt injection attacks are a critical security vulnerability in AI systems where hidden instructions within user data (like emails or documents) can hijack AI assistants such as ChatGPT, Claude, and Gemini. The Open Worldwide Application Security Project (OWASP) ranks prompt injection as the number one threat for AI applications. These attacks work by embedding malicious commands that override the AI's original instructions, causing it to perform unauthorized actions like forwarding sensitive data. The article explains how these attacks work, why they are difficult to prevent (with OpenAI acknowledging the problem may never be fully solved), and offers guidance on how to stay safe.
