The emerging reconfigurable intelligent surface (RIS) technique introduces novel threats to wireless sensing owing to its channel customization ability. Unlike active radios, the RIS’s interference behaves akin to natural reflections, exhibiting a higher level of stealthiness and difficulty in detection. However, the majority of current RIS-based attacks lack generalizability to real-world scenarios, as they assume complete coverage of the RIS over objects and develop their techniques within electromagnetic-controlled environments such as an anechoic chamber.
