RAG Data Poisoning: Retrieval-Augmented Generation Integr...
Definition
RAG data poisoning is an adversarial attack where manipulated or malicious data is surreptitiously injected into the external knowledge base (e.g., vector store, document repository) utilized by a Retrieval-Augmented Generation (RAG) system. This injection aims to subvert the integrity of the retrieved context, causing the Large Language Model (LLM) to generate biased, inaccurate, or harmful responses by leveraging the compromised information during the generation phase.
Why It Matters
This vulnerability can lead to catastrophic production failures, including the generation of factually incorrect or misleading information, unauthorized data exposure (e.g., PII/PHI), and the execution of malicious instructions embedded within the poisoned context that could trigger unauthorized API calls, data manipulation, or system compromise, severely impacting operational integrity and regulatory compliance.
How Exogram Addresses This
Exogram's 0.07ms deterministic policy rules intercept and analyze the retrieved context and the final constructed prompt *before* it reaches the LLM for generation. By enforcing granular policies on data schema, semantic content, and behavioral patterns within the retrieved documents and the prompt, Exogram can detect and block payloads containing known adversarial patterns, anomalous data structures, or instructions that violate predefined security postures, thereby preventing the poisoned data from influencing the LLM's output and mitigating the attack at the execution boundary.
