LogoStyleFool: Vitiating Video Recognition Systems via Logo Style Transfer

1 code implementation15 Dec 2023 Yuxin Cao, Ziyu Zhao, Xi Xiao, Derui Wang, Minhui Xue, Jin Lu

We separate the attack into three stages: style reference selection, reinforcement-learning-based logo style transfer, and perturbation optimization.

The "Beatrix'' Resurrections: Robust Backdoor Detection via Gram Matrices

1 code implementation23 Sep 2022 Wanlun Ma, Derui Wang, Ruoxi Sun, Minhui Xue, Sheng Wen, Yang Xiang

However, recent advanced backdoor attacks show that this assumption is no longer valid in dynamic backdoors where the triggers vary from input to input, thereby defeating the existing defenses.

STRIP: A Defence Against Trojan Attacks on Deep Neural Networks

4 code implementations18 Feb 2019 Yansong Gao, Chang Xu, Derui Wang, Shiping Chen, Damith C. Ranasinghe, Surya Nepal

Since the trojan trigger is a secret guarded and exploited by the attacker, detecting such trojan inputs is a challenge, especially at run-time when models are in active operation.

Android HIV: A Study of Repackaging Malware for Evading Machine-Learning Detection

no code implementations10 Aug 2018 Xiao Chen, Chaoran Li, Derui Wang, Sheng Wen, Jun Zhang, Surya Nepal, Yang Xiang, Kui Ren

In contrast to existing works, the adversarial examples crafted by our method can also deceive recent machine learning based detectors that rely on semantic features such as control-flow-graph.
