Abstract
Large language models (LLMs) have demonstrated remarkable performance across a wide range of natural language processing tasks, yet their deployment in high-stakes applications has raised critical concerns regarding reliability, safety, and response trustworthiness. In this paper, we present a red teaming framework that systematically uncovers vulnerabilities in LLM outputs. Our approach employs a novel multi-role architecture comprising a target, attackers, and jury models. The attackers generate increasingly effective adversarial prompts while the jury rigorously evaluates response accuracy and consistency across tasks. In a case study, our red teaming strategy proved particularly effective at exposing unfaithfulness in LLM responses. Exploitative adversarial prompts increased the attack success rate by up to 7.9% in question-answering tasks, revealing vulnerabilities in the LLMs’ reliability. The approach successfully identifies how structural constraints in summarization tasks can significantly influence vulnerability patterns, with format limitations demonstrating measurable improvements in model faithfulness. It demonstrates that architectural design choices typically outweigh parameter scaling in determining model safety. The framework’s key strength lies in its adaptability across different evaluation tasks, from English question-answering to Arabic summarization, enabling comprehensive comparison of model vulnerabilities. While our approach excels at comparing cross-model and cross-linguistic vulnerabilities, it faces challenges in fully automating the generation of effective adversarial prompts across different languages. Moreover, our experiments also reveal limitations in detecting certain subtle forms of unfaithfulness that do not manifest as explicit factual contradictions, particularly when working across different linguistic contexts. Overall, this red teaming architecture provides both actionable insights into current LLM vulnerabilities and a scalable methodology for ongoing safety evaluation as models continue to evolve.
This work proposes an explanation-aware safety framework that augments binary harmfulness detection with structured, human-interpretable explanations capturing severity, strategies, trigger spans, ratio-nales, and derived safety factors, and introduces a human–LLM hybrid annotation and canonicaliza-tion pipeline.

This work presents the most comprehensive evaluation of LLM safety capabilities to date, systematically testing models across datasets that are organized into four distinct categories, and uncovers critical blind spots.
Safety-aligned large language models are trained to refuse harmful requests, yet embedding the same requests in particular scenarios can bypass their safeguards. Existing red-teaming methods empirically identify effective scenarios through observed attack outcomes, but why particular scenarios weaken refusal remains mechanistically unclear. Meanwhile, mechanistic interpretability studies have characterized both refusal directions and jailbreak-associated features, without explaining the relationship between the two representations. In this work, we show that scenario-wrapped prompts activate internal scenario directions whose causal steering consistently reduces refusal scores. Building on this finding, we propose \textsc{Concept2Scenario}, a concept-based attribution framework for vulnerable scenario discovery. It instantiates a broad concept space with a sparse autoencoder, attributes refusal suppression to individual concepts, translates the identified concepts into interpretable natural-language scenarios, and identifies synergistic scenario combinations through interaction attribution. Across three open-source models, two safety benchmarks, and six black-box jailbreak methods, the discovered scenarios serve as reusable priors that improve average attack success rates by up to $18.2$ percentage points. They also transfer to GPT-5, Claude-Haiku-4.5, and Gemini-3-Flash, suggesting that some scenario-level refusal vulnerabilities are shared across model families. Moreover, the identified combinations outperform their individual constituents and enable iterative attacks to succeed in fewer turns.

With the rapid development and widespread deployment of large language models (LLMs), the security and robustness of these models have emerged as critical research topics. Among various threats, jailbreak attacks, which aim to circumvent built‐in safety mechanisms, have garnered considerable attention as a key means of breaching model protections. However, existing jailbreak methods still face several limitations, such as excessive reliance on the model's internal capabilities, high attack costs and insufficiently comprehensive evaluation strategies. To address these challenges, we propose a novel jailbreak framework: YAE. This method enhances the model's dependency on external information by constructing a RAG‐based knowledge base containing harmful Q&A content. It also leverages Guide MoE, a routing‐inspired prompting strategy, to guide the model toward alternative reasoning trajectories through expert‐role prompting and domain‐specific perturbations, thereby inducing more deceptive responses. Furthermore, Adversarial Fine‐Tuning is employed to further optimize the performance of jailbreak attacks. We conduct extensive experiments under various settings, and the results demonstrate that YAE achieves state‐of‐the‐art performance in terms of both attack success rate (ASR) and efficiency, highlighting its strong overall effectiveness.
Experiments show that with only 1K synthesized samples, AdvSafe-aligned LRMs achieve significantly stronger jailbreak robustness than existing baselines, with almost no utility degradation, demonstrating that learning unsafety knowledge enables a superior robustness-utility trade-off and generalizes beyond seen attack patterns.
