An attack that manipulates the vector embeddings stored in a knowledge base to control what information an AI system retrieves and presents to users. By inserting carefully crafted documents that produce specific embedding patterns, attackers can ensure their malicious content ranks highest in similarity searches. This is an indirect way to influence LLM outputs without modifying the model itself.

Why Embedding Poisoning Matters for Your Cybersecurity Career

As RAG-based AI systems become standard in enterprises, the integrity of embedding databases becomes a security concern. Security engineers building AI applications must validate source documents, monitor for anomalous embedding patterns, and implement integrity checks on the retrieval pipeline. This attack vector is specific to the AI era and requires new defensive skills.
