X-Transfer Attacks: Towards Super Transferable Adversarial Attacks on CLIP

Baseline attacker Meta-UAP used in ICML2025 paper "X-Transfer Attacks: Towards Super Transferable Adversarial Attacks on CLIP"

X-TransferBench

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: DenseNet121, VGG16, and ResNet50
Surrogate Dataset: MSCOCO
Threat Model: L_inf_eps=12/255
Perturbation Size: 3 x 224 x 224

Model Usage

from XTransferBench import attacker

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