VerifiedLLM architectures cannot strictly distinguish between 'instructions' and 'data' at the semantic level, which is the root cause of why prompt injection is difficult to fundamentally eliminate.82% similarVerifiedPrompt injection is essentially an instruction hijacking attack that exploits the structural flaw of LLMs being unable to distinguish system instructions from user data at the semantic level, and is conceptually similar to SQL injection.81% similarUnverifiedPrompt injection attacks do not need to exploit software vulnerabilities; they exploit the model's difficulty in distinguishing instructions from data.79% similarUnverifiedThe Scope layer restricts the tools, data sources, and external services an agent can call before LLM inference, effectively defending against prompt injection attacks.75% similarUnverifiedThe tool should return a clear error message upon blocking (such as "all proxy nodes are currently rate-limited by the target host"), letting the LLM treat the failure as an unrecoverable state and thus switch strategies rather than retry.69% similar
