If you control the blinking of the led you have established a very low bandwidth communication channel.

  Ohhh I misunderstood; I thought they were stealing data by simply observing the blinking LED, not that they had infiltrated the computer and were controlling the LED.

    The term "exfiltrate" implies that the data is being "pushed" or otherwise sent outward from the machine, as opposed to being harvested from the outside.

    Thank you, because you wrote this, I too now understand what they meant. My train of thought was apparently on the same track as yours!

    Allmost (or all?) of those attacks are only possible, if the target computer is infected. And the scenario is that the virus wants to send data out, to a nearby decice which is also infected.

      Which is why this is "exfiltration", not "infiltration".
