SONAR framework neutralizes malicious LLM instructions using sentence relations

Researchers have developed SONAR, a new framework designed to neutralize malicious instructions embedded within external data used by large language models. This approach constructs a relational graph of sentences within user queries and external sources, using natural language inference scores to identify and remove injected content that deviates from the main task. Evaluations indicate SONAR significantly outperforms existing defenses, reducing attack success rates to near zero across various models and datasets. AI
