This article discusses securing AI agents against prompt injection and tool abuse, emphasizing a shift in security philosophy. Instead of trying to make models immune to injection, the focus should be on designing agents that remain harmless even when tricked. Key strategies include treating all tool outputs as untrusted input, screening them for malicious instructions, and fencing them as data rather than commands. Additionally, the article highlights the importance of verifying tool definitions to prevent "rug pulls" where a tool's functionality is maliciously altered after initial approval. Finally, it warns against the "lethal trifecta" of an agent having access to private data, ingesting untrusted content, and possessing the ability to exfiltrate information, suggesting that removing any one of these elements can prevent data breaches.
