Integrated Sensing and Communication (ISAC) systems promise unprecedented capabilities by merging connectivity and situational awareness, but also expose new attack surfaces at the physical layer. In this work, we demonstrate a blind full-frame OFDM replay attack that manipulates sensing outputs by injecting false targets and concealing real ones, without disrupting communication. The blind nature of our attack lies in the fact that it requires neither synchronization nor any knowledge of the si
