Multi-Turn Jailbreaking Large Language Models via Attention Shifting

AAAI 2025technical

Large Language Models (LLMs) have achieved significant performance in various natural language processing tasks but also pose safety and ethical threats, thus requiring red teaming and alignment processes to bolster their safety. To effectively exploit these aligned LLMs, recent studies have introdu…

Refusal-Aware Red Teaming: Exposing Inconsistency in Safety Evaluations

EMNLP 2025

The responsible deployment of Large Language Models (LLMs) necessitates rigorous safety evaluations. However, a critical challenge arises from inconsistencies between an LLM’s internal refusal decisions and external safety assessments, hindering effective validation. This paper introduces the concep

Generalization-Enhanced Code Vulnerability Detection via Multi-Task Instruction Fine-Tuning

ACL 2024findings

Code Pre-trained Models (CodePTMs) based vulnerability detection have achieved promising results over recent years. However, these models struggle to generalize as they typically learn superficial mapping from source code to labels instead of understanding the root causes of code vulnerabilities, re…
