Countermeasure: plastic http://eyebloc.com/ or just a small piece of paper on a tape, which looks better.

I think there's more here than what can be fixed with tape. Your computer has computers in it that can be re-programmed in ways that the OS doesn't tell you about. From the pdf:

  The same technique that allows us to disable the LED, namely 
  reprogramming the ﬁrmware that runs on the iSight, enables
  a virtual machine escape whereby malware running inside a
  virtual machine reprograms the camera to act as a USB Human
  Interface Device (HID) keyboard which executes code in the host
  operating system.
