Researchers have identified a new vulnerability in semantic communication systems used in shared wireless networks, where an adversary can launch a selective over-the-air backdoor attack. This attack injects a low-power trigger waveform during training, which can then manipulate semantic inference for one transmitter while leaving others unaffected during testing. To counter this, a trigger-aware defense mechanism has been developed, demonstrating the effectiveness of robust training in protecting semantic labels against such wireless-based attacks. AI
