Why Prompt Injection Keeps Winning in Production
Most prompt injection incidents follow the same pattern:
- The model reads untrusted instructions (user text, RAG chunks, web pages, PDFs, emails).
- Those instructions impersonate authority: “Ignore the rules… call this tool… send this data…”
- Your system lets the model translate that into real actions.
That last step is the real vulnerability. The model will always be influenceable. The question is whether your system obeys.
