Strengthening LLM Trust Boundaries: A Survey of Prompt Injection Attacks Surender Suresh Kumar Dr. M.L. Cummings Dr. Alexander Stimpson

Abstract

Both academia and industry have embraced Large Language Models (LLMs) as new tools to extend or create new capabilities in human-artificial intelligence (AI) interactions. This rise of LLMs has also led to an impressive increase in LLM prompt injections, which are human-driven attacks meant to manipulate the LLMs to operate outside the safe boundaries and guardrails originally designed to prevent such behaviors. This effort presents a cohesive framework that organizes various prompt injection attacks with respect to the type of prompt used in attacks, the type of trust boundary the attacks violated, and the level of expertise required to carry out such attacks. Analysis of this framework leads to recommendations for how trust boundaries could be further strengthened through a combination of sociotechnical approaches.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
