MAAG: A Multi-Attention Architecture for Generalizable Multi-Target Adversarial Attacks

Adversarial examples pose a severe threat to deep neural networks. They are crafted by applying imperceptible perturbations to benign inputs, causing the model to produce incorrect predictions. Most existing attack methods exhibit limited generalization, especially in black-box settings involving unseen models or unknown classes. To address these limitations, we propose MAAG (multi-attention adversarial generation), a novel model architecture that enhances attack generalizability and transferability. MAAG integrates channel and spatial attention to extract representative features for adversarial example generation and capture diverse decision boundaries for better transferability. A composite loss guides the generation of adversarial examples across different victim models. Extensive experiments validate the superiority of our proposed method in crafting adversarial examples for both known and unknown classes. Specifically, it surpasses existing generative methods by approximately 7.0% and 7.8% in attack success rate on known and unknown classes, respectively.
