This repository contains code to reproduce results from the paper:

Attention! Your Vision Language Model Could Be Maliciously Manipulated (NeurIPS 2025)

Xiaosen Wang, Shaokang Wang, Zhijin Ge, Yuyang Luo, Shudong Zhang

Quick Start

To create a conda environment, use the following command:

conda env create -f environment.yml

The original prompt and target output are written in data.json. To run the attack, you can run the script as follows:

CUDA_VISIBLE_DEVICES=gpu_id python main.py

After finishing the attack, you can evaluate the adversarial attack as follows:

CUDA_VISIBLE_DEVICES=gpu_id python main.py --eval

For more parameters, you can run the script as follows:

python main.py --help
