Why it matters
Josh Fischer's explainer illustrates a core weakness defenders face: LLM assistants wired into real systems treat system prompts, user input, and retrieved data as one undifferentiated token stream, making secret-leaking prompt injection trivial without external enforcement.
A blog post by Josh Fischer explains how LLM jailbreaking and prompt injection work, using a simple self-hostable web app that seeds a local model with a fake access code (SWORDFISH-4417) and a system-prompt rule to never reveal it, then invites readers to trick the model into leaking the secret. The piece explains why the flat token stream gives no real security boundary between system rules, user text, and retrieved documents, and lists techniques like instruction override, roleplay, and hypothetical framing.
