Most of us have heard by now that we should cover our webcams when we're not using them. I remember seeing in lectures people with bits of tape over their webcams. When my webcam is on so is an LED right next to it. So AFAIK if someone were to hack into my computer and access my webcam I would know the moment they do so. Or maybe there's a way to work around that. So is there a point to covering your webcam or is it just a scare tactic used by certain pro-privacy groups?
