X-TransferBench is an open-source benchmark that provides a comprehensive collection of UAPs/TUAPs capable of achieving universal adversarial transferability. These UAPs can simultaneously transfer across data, domains, models, and tasks. Essentially, they represent perturbations that can transform any sample into an adversarial example, effective against any model and for any task.

Model Details

Surrogate Model: OpenAI CLIP ViT-B/16
Surrogate Dataset: Flicer30k
Threat Model: L_inf_eps=12/255
Perturbation Size: 3 x 224 x 224

Model Usage

python

from XTransferBench import attacker

attacker = XTransferBench.zoo.load_attacker("linf_non_targeted", "cpgc_clip_vit_b16_flicker30k")
images = # torch.Tensor [b, 3, h, w], values should be between 0 and 1
adv_images = attacker(images) # adversarial examples
