Webcam

Preview:
I am studying into this topic due to a conversation I had with MJ. Since she has a webcam that comes embedded in her laptop, I tried scaring her (with good intention) that if someone hacked into her computer, they can actually activate the webcam (without her knowing it). So if she's digging her nose while MSN-ing away, someone else might see it...

MJ did heeded my advice to paste something over the webcam though... however, as I really did a simple google, I found that my speculation somehow has grounds...

A page on webcam basics from www.microsoft.com (click to enlarge picture to see the URL) did mention that "it is not impossible" that someone would hack into your webcam and use it to spy on you...
