Jeff Gamet at The MacObserver tells us in a piece titled Researchers Hacked into MacBook Camera, but that Doesn’t Mean They’re Spying on You that two researchers have found a way to disable that little green light, which lets you know that your camera is on. Don’t despair though; this only works on older Macs. Plus, it requires a firmware hack.

Two researchers have found a way to disable the green light on your Mac laptop that lets you know when the built-in camera is active, giving hackers a potential way to spy on you remotely. Just because it’s possible, however, doesn’t mean it’s practical. In other words, there isn’t much chance of your Mac being used to watch what you’re doing without your knowledge.
