BadToken: Token-level Backdoor Attacks to Multi-modal Large Language Models

CVPR 2025poster

Multi-modal large language models (MLLMs) extend large language models (LLMs) to process multi-modal information, enabling them to generate responses to image-text inputs. MLLMs have been incorporated into diverse multi-modal applications, such as autonomous driving and medical diagnosis, via plug-a…

Merge Hijacking: Backdoor Attacks to Model Merging of Large Language Models

ACL 2025long

Model merging for Large Language Models (LLMs) directly fuses the parameters of different models finetuned on various tasks, creating a unified model for multi-domain tasks. However, due to potential vulnerabilities in models available on open-source platforms, model merging is susceptible to backdo…

You Are Catching My Attention: Are Vision Transformers Bad Learners Under Backdoor Attacks?

CVPR 2023poster

Vision Transformers (ViTs), which made a splash in the field of computer vision (CV), have shaken the dominance of convolutional neural networks (CNNs). However, in the process of industrializing ViTs, backdoor attacks have brought severe challenges to security. The success of ViTs benefits from the…
