Why it matters
RAG poisoning turns a transient prompt attack into a long-lived integrity problem in the knowledge layer, meaning defenders must enforce source trust, content provenance, and refresh discipline rather than treating each prompt in isolation.
An explainer from NHI Management Group discusses why RAG poisoning poses a more persistent risk than a single prompt injection: malicious content ingested into a retriever, chunk store, or indexed corpus can persist and shape outputs across many users, queries, and downstream agent actions until removed or reindexed. It contrasts one-off context abuse with durable integrity failures in the knowledge layer, referencing MITRE ATLAS for adversarial-AI patterns.
