📝 Publications & Research

$^\dagger$: Equal contribution, $^*$: Corresponding author

  • EVA: Red-Teaming GUI Agents via Evolving Indirect Prompt Injection
    Preprint, submitted to NeurIPS 2025.
    [arXiv]
    This project proposes a black-box, feedback-driven evolutionary framework for red-teaming GUI agents against indirect prompt injection. By dynamically evolving a word corpus based on the agent’s interactive feedback, EVA significantly improves attack success rates (e.g., from 48% to 80% in popup scenarios) and reveals key vulnerabilities related to attentional focus and semantic overlap, offering actionable insights for defense.
  • PoisonBench: A Fine-Grained Direct Injection Benchmark for Robustness Evaluation in Retrieval-Augmented Generation with Large Language Models
    Preprint, submitted to AAAI 2026.
    We introduce PoisonBench, the first bilingual (Chinese-English) benchmark focused on templated direct injection attacks in RAG systems. It features six fine-grained poisoning templates based on cognitive biases (e.g., authority citation, statistical misdirection). Our experiments on mainstream LLMs show a significant drop in accuracy (up to 27.4 percentage points), demonstrating that models’ internal knowledge is easily overridden by rhetorically strong but factually weak contexts.
  • Smart Sound Guidance - IoT Voice Attack Defense System
    [Project Homepage] | [Code]
    This project addresses the deficiencies of traditional voice attack defense systems. We designed a comprehensive solution featuring an intelligent attack detection model (88.7% accuracy), a crowdsensing monitoring platform, and a threat warning system, effectively enhancing the security of IoT devices against voice-based threats. This work, which I led, won the First Prize in the National Final of the China Collegiate Computing Contest.
  • HaMonitorSentry - High-rise Building Intelligent Monitoring System
    [Project Homepage] | [Code] | [Docs]
    Focusing on dual-angle monitoring, this system integrates algorithms for detecting falling objects and recognizing dangerous high-rise behaviors. We introduced techniques like inter-class distance knowledge distillation and a Mask-Attention module to improve detection accuracy and real-time performance in complex scenes. This work won the First Prize in the National Final of the China Robot and Artificial Intelligence Competition.
  • FuzzLLM - A Novel Universal Fuzzing Framework for Actively Discovering LLM Jailbreak Vulnerabilities
    [Project Homepage] | [Code]
    Inspired by traditional fuzzing, FuzzLLM deconstructs jailbreak prompts and automatically generates a large volume of structured test cases. This highly automated framework can efficiently identify potential security vulnerabilities in LLMs in a black-box setting, enabling proactive defense. The project has resulted in one National Invention Patent and one Software Copyright.
