BEAGLE: Forensics of Deep Learning Backdoor Attack for Better Defense

1 code implementation16 Jan 2023 Siyuan Cheng, Guanhong Tao, Yingqi Liu, Shengwei An, Xiangzhe Xu, Shiwei Feng, Guangyu Shen, Kaiyuan Zhang, QiuLing Xu, Shiqing Ma, Xiangyu Zhang

Attack forensics, a critical counter-measure for traditional cyber attacks, is hence of importance for defending model backdoor attacks.

Detecting Backdoors in Pre-trained Encoders

1 code implementation CVPR 2023 Shiwei Feng, Guanhong Tao, Siyuan Cheng, Guangyu Shen, Xiangzhe Xu, Yingqi Liu, Kaiyuan Zhang, Shiqing Ma, Xiangyu Zhang

We show the effectiveness of our method on image encoders pre-trained on ImageNet and OpenAI's CLIP 400 million image-text pairs.

Fusion is Not Enough: Single Modal Attacks on Fusion Models for 3D Object Detection

no code implementations28 Apr 2023 Zhiyuan Cheng, Hongjun Choi, James Liang, Shiwei Feng, Guanhong Tao, Dongfang Liu, Michael Zuzak, Xiangyu Zhang

We argue that the weakest link of fusion models depends on their most vulnerable modality, and propose an attack framework that targets advanced camera-LiDAR fusion-based 3D object detection models through camera-only adversarial attacks.
