Adversarial Attack and Defense on Language Models

Overview Speaker: Ibrahim Al Azher Date: Friday, September 18, 2026, 2:30 PM Room: PM103 This session covers adversarial attacks on language models and the defenses against them, organized in three parts: attacks, defenses, and tool-based attack and defense. The reading list for each part is below. Relevant Materials Attack Universal and Transferable Adversarial Attacks on Aligned Language Models Improved Techniques for Optimization-Based Jailbreaking on Large Language Models Tree of Attacks: Jailbreaking Black-Box LLMs Automatically PANDORA: Jailbreak GPTs by Retrieval Augmented Generation Poisoning A Gradient Control Method for Backdoor Attacks on Parameter-Efficient Tuning FLASH: Focused Layer Attention Sink Hijacking Defense Safety Alignment Should Be Made More Than Just a Few Tokens Deep AGD: Adversarial Game Defense Against Jailbreak Attacks in Large Language Models Mitigating Fine-tuning based Jailbreak Attack with Backdoor Enhanced Safety Alignment AutoDefense: Multi-Agent LLM Defense against Jailbreak Attacks Defending Large Language Models Against Jailbreak Attacks via Layer-specific Editing Tool-Based Attack and Defense Same Payload, Different Channel: Measuring Trust Asymmetry in Tool-Using Language Models Mind the GAP: Text Safety Does Not Transfer to Tool-Call Safety in LLM Agents Prompt Injection as Role Confusion LLMs Encode Harmfulness and Refusal Separately When Safety Speaks a Language: A Mechanistic Analysis of Safety–Language Identity Entanglement in LLMs Refusal in Language Models Is Mediated by a Single Direction Attention Slipping: A Mechanistic Understanding of Jailbreak Attacks and Defenses in LLMs ASIDE: Architectural Separation of Instructions and Data in Language Models (ICLR 2026)

Systematic Security Analysis of Cellular Network Specifications and Implementations

Overview On April 11, 2025, we were honored to host Dr. Imtiaz Karim, a Postdoctoral Researcher at Purdue University and incoming Assistant Professor at the University of Texas at Dallas, for a distinguished research talk titled “Systematic Security Analysis of Cellular Network Specifications and Implementations.” Dr. Karim presented a compelling overview of the security challenges in modern cellular networks, particularly 4G and 5G, and introduced CellularLint, a cutting-edge tool that uses large language models to identify inconsistencies in cellular specifications. He further discussed his methodologies for analyzing protocol implementations and revealed a range of vulnerabilities that have influenced updates to industry standards. The talk concluded with Dr. Karim’s vision for securing future wireless communication systems, including 6G. We sincerely thank Dr. Karim for sharing his impactful research and insights with our department.
