I've made series of pentests in my network and one of the things I've tried was record webcam and microphone. Recording microphone seems for final users a stealth thing. But what about the webcam? In my tests, the indicator is turned on and I can't figure out a way to do this without turn on the light.
So far I'm assuming that if someone break into my computer and turn on the webcam, I'll know that. But, since it's possible to avoid the light through firmware change, which technique should I use to detect the webcam use?
It's a built-in Microsoft USB 2.0 Camera, using Driver 6.1.7601.17586 on a Gigabyte W566U Notebook; running Windows 7 Professional 64 bits.
I guess to be prone I need something hardware specific.
