The ability of the light-emitting diodes (LED) on a keyboard to send data at a rate that is far greater than the human eye can perceive has been fully studied. However, an IP camera can only fetch high-resolution images at a low frame rate. It is unable to act as a sink of the optical covert channel directly. In our paper, a novel form of modulation is proposed to modulate the LEDs on a keyboard. The modulated signal can be received by a nearby IP camera. To verify its validity, we implement a prototype of exfiltration malware. Our experiment shows a significant improvement in the imperceptibility of covert communication. Against the background of the Internet of Things (IoT), it is possible to leak data covertly to IP cameras across air-gapped networks via LED keyboard status indicators. |
