Papers
- SALAD-Bench: A Hierarchical and Comprehensive Safety Benchmark for Large Language Models (2024 · 119 citations)
Existing LLM safety benchmarks have several weaknesses. They cover narrow slices of harm, and modern models now handle their questions almost perfectly. Many also need slow human grading or costly GPT grading, and few can assess both models and attack/defense techniques. SALAD-Bench addresses these gaps with a… - Layer-Aware Representation Filtering: Purifying Finetuning Data to Preserve LLM Safety Alignment (2025 · 11 citations)
Fine-tuning a safety-aligned LLM can weaken its refusal behaviour even when the training data look harmless. - Visual Contextual Attack: Jailbreaking MLLMs with Image-Driven Context Injection (2025 · 6 citations)
The paper argues that most image-based jailbreaks of multimodal LLMs use the picture as a trigger. They paint harmful text onto it, add adversarial noise, or generate a loosely related image, but the visual content rarely defines a coherent scenario. The authors introduce a vision-centric jailbreak setting, where the… - ToolSafe: Enhancing Tool Invocation Safety of LLM-based agents via Proactive Step-level Guardrail and Feedback (2026 · 3 citations)
LLM agents that call external tools can be steered into harmful actions, either by malicious users or by prompt injections hidden in tool outputs.
