A Simulation Framework for Electromagnetic Signal Injection Attacks on Image Sensors
Youqian Zhang, MK Michael Cheung, Chunxi Yang +6
Image sensors are fundamental to many intelligent systems, allowing visual perception and AI-driven decision-making. However, their integrity can be compromised by electromagnetic…
Poster: Exploring the Limits of Audio-Based Detection of Turkish Phone Call Scams
Arda Eren, Micheal Cheung, Youqian Zhang +2
Scam phone calls exploit vulnerable communities worldwide, yet research on detection has focused almost exclusively on English and other high-resource languages. In low-resource se…
AI Security Research Should Better Incentivize Defense Research
Youqian Zhang
This work examines an imbalance in artificial intelligence (AI) security research: the field tends to produce more work on attacking AI systems than on defending them. Drawing on r…
Phantom Force: Injecting Adversarial Tactile Perceptions into Embodied Intelligence via EMI
Zirui Kong, Youqian Zhang, Sze Yiu Chau
Embodied intelligent robots rely on tactile sensors to interact with the physical world safely. While the security of visual perception systems has been studied (e.g., adversarial…
