Data-Free Universal Attack by Exploiting the Intrinsic Vulnerability of Deep Models

AAAI 2025technical

Deep neural networks (DNNs) are susceptible to Universal Adversarial Perturbations (UAPs), which are instance-agnostic perturbations that can deceive a target model across a wide range of samples. Unlike instance-specific adversarial examples, UAPs present a greater challenge as they must generalize…
