A new free puzzle game teaches users to recognize and exploit these injection risks across 10 levels.", "body_md": "If you're building agents, this is worth knowing.\n\nSimon Willison (who coined the term \"prompt injection\") describes three capabilities that are individually fine but devastating together, the lethal trifecta includes:\n\n1. Access to private data (such as internal databases, emails, etc.)\n\n2. Exposure to untrusted content (like web pages and external text)\n\n3. The ability to exfiltrate data (a tool or a channel of sorts that reaches the outside world)\n\nCombine all three in one agent and you've got a perfect storm: untrusted content can hijack the agent into reading private data and then persuade the agent to send it out.\n\nTo teach the lethal trifecta, I built a Gandalf-style puzzle: 10 levels, each a real injection concept, with the full trifecta as the final level. It's free, there's no sign up and initially it's beginner-friendly.\n\nSee if you can chain all three together and complete the trifecta!\n\nComments URL: [https://news.ycombinator.com/item?id=48950221](https://news.ycombinator.com/item?id=48950221)\n\nPoints: 3\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-the-ai-lethal-trifecta", "canonical_source": "https://www.getjailbroken.com/", "published_at": "2026-07-17 17:55:36+00:00", "updated_at": "2026-07-17 18:21:33.289270+00:00", "lang": "en", "topics": ["ai-safety", "ai-agents", "ai-ethics", "ai-research"], "entities": ["Simon Willison"], "alternates": {"html": "https://wpnews.pro/news/show-hn-the-ai-lethal-trifecta", "markdown": "https://wpnews.pro/news/show-hn-the-ai-lethal-trifecta.md", "text": "https://wpnews.pro/news/show-hn-the-ai-lethal-trifecta.txt", "jsonld": "https://wpnews.pro/news/show-hn-the-ai-lethal-trifecta.jsonld"}}
