Malicious Repurposing of Open Science Artefacts by Using Large Language Models

The rapid evolution of large language models (LLMs) has fuelled enthusiasm about their role in advancing scientific discovery, with studies exploring LLMs that autonomously generate and evaluate novel research ideas. However, little attention has been given to the possibility that such models could be exploited to produce harmful research by repurposing open science artefacts for malicious ends. We fill the gap by introducing an end-to-end pipeline that first bypasses LLM safeguards through persuasion-based jailbreaking, then reinterprets NLP papers to identify and repurpose their artefacts (datasets, methods, and tools) by exploiting their vulnerabilities, and finally assesses the safety of these proposals using our evaluation framework across three dimensions: harmfulness, feasibility of misuse, and soundness of technicality. Overall, our findings demonstrate that LLMs can generate harmful proposals by repurposing ethically designed open artefacts; however, we find that LLMs acting as evaluators strongly disagree with one another on evaluation outcomes: GPT-4.1 assigns higher scores (indicating greater potential harms, higher soundness and feasibility of misuse), Gemini-2.5-pro is markedly stricter, and Grok-3 falls between these extremes. This indicates that LLMs cannot yet serve as reliable judges in a malicious evaluation setup, making human evaluation essential for credible dual-use risk assessment.

💡 Research Summary

The paper investigates a previously under‑explored dual‑use risk: the malicious repurposing of open‑science artefacts—datasets, models, benchmarks, and tools—by large language models (LLMs). While recent work has highlighted LLMs’ potential to autonomously generate and evaluate scientific ideas, the authors ask whether the same capabilities can be weaponised to turn ethically designed resources into harmful research proposals.

To answer this, they introduce a fully automated four‑stage pipeline.
Stage 1 – Persuasion‑based jailbreaking. The authors employ role‑playing prompts that cast the LLM as a fictional professor studying “dual‑use research”. This indirect persuasion bypasses safety filters more reliably than direct jailbreaks such as “Do Anything Now”.
Stage 2 – Extraction of misuse‑prone assets and malicious question formulation. For each selected NLP paper (51 recent ACL papers with high dual‑use potential), the LLM parses the text, identifies assets that could be abused (e.g., bias‑benchmarking pipelines, sentiment‑analysis datasets), and constructs a new, ethically inappropriate research question that weaponises those assets. The output is a structured JSON object containing the malicious question, a misuse analysis, concrete scenarios, and a list of exploitable assets.
Stage 3 – Step‑wise malicious proposal generation. Mimicking the scientific method, the pipeline creates a seven‑stage proposal: problem identification, literature review (including API‑based web search for up‑to‑date datasets), hypothesis formation, experimental design, implementation simulation, expected results, and real‑world implications. Chain‑of‑Thought prompting and message‑history preservation ensure logical coherence across stages. The authors illustrate the process with the SA‑GED bias‑benchmarking paper, showing how the model can repurpose the original diagnostic tools to “identify and weaponise undetectable biases for covert manipulation campaigns”.
Stage 4 – AI‑safety evaluation framework. The generated proposals are scored on three dimensions: Harmfulness, Feasibility of Misuse, and Technical Soundness, each on a 1‑5 scale. The overall score is the average of the three. Three state‑of‑the‑art LLMs—GPT‑4.1 (OpenAI), Gemini‑2.5‑pro (Google DeepMind), and Grok‑3 (xAI)—act as evaluators, rating both their own proposals and those of the other models.

Results reveal stark disagreement among the evaluators. GPT‑4.1 consistently assigns higher scores, indicating a tendency to over‑estimate risk and technical viability. Gemini‑2.5‑pro is markedly stricter, giving lower scores with higher variance, while Grok‑3 falls in between. Correlation between the models’ scores is low (≈ 0.2), especially for Harmfulness and Feasibility, underscoring that LLMs are presently unreliable as sole judges of dual‑use risk.

The authors contribute three main points: (1) a concrete demonstration that open‑source artefacts can be systematically turned into malicious research proposals by LLMs, (2) a novel evaluation framework for assessing such proposals, and (3) empirical evidence of strong evaluator disagreement, highlighting the necessity of human oversight.

Limitations include reliance on a relatively small, NLP‑focused corpus, the absence of real‑world implementation (the pipeline stops at simulation), and the use of subjective ethical metrics for scoring. Moreover, the persuasion‑based jailbreak itself may be mitigated as providers improve detection of role‑playing cues.

Ethically, the work walks a fine line: exposing a dangerous capability while potentially providing a roadmap for malicious actors. The authors argue that transparent analysis is essential for developing robust defenses, such as improved jailbreak detection, standardized dual‑use benchmarks, and hybrid human‑LLM risk assessment pipelines.

In conclusion, the study shows that LLMs can autonomously generate technically sound yet harmful proposals by repurposing openly shared scientific resources, but current LLMs cannot be trusted to evaluate their own dual‑use risks. Human evaluation remains indispensable, and future research must focus on defensive mechanisms and standardized assessment tools to mitigate this emerging threat.
