Someone Can Spy On You Using Your Own MacBook Webcam

Belive it or not, a hacker could be spying on you through your MacBook Webcam right now. Thats because its possible for hackers or even federal
government to bypass the security feature in isight camera, researches at
Johns Hopkins University say. The camera lights up green when it's on. It's actually a security feature to notify you that the camera is on and someone may be able to see you. Hackers can use a piece of software called a Remote Administration tool to get the security feature. RAT allows people to control a computer from anywhere on the internet to turn on the isight camera without turning on the light.

Hackers can  accomplish this by reprogramming the chip inside the camera, known as a micro-controller, to allow the camera and light to activate. This only effects only earlier models of Apple's products, like the iMac G5, and its early Intel-based iMacs, MacBooks, and MacBook Pros untill aroung 2008. It might be possible that the attack could be used on newer systems, Twitter security Charlie Miller told the Washington Post.
So what can you do to protect yourself?
Stick a piece of tape on your camera, Miller says. seriously.
