Research shows how MacBook Webcams can spy on their users without warning
Honestly, I don’t understand why it’s so difficult to create a camera chip not susceptible to any software hack. The camera sensor needs electrical current to work. Simply place the LED inline or in parallel to the camera and you are done. Any time current is sent to the camera sensor, the LED cant help it but light up. My knowledge of electronics is limited, but I know for a fact that this can be achieved without the use of any reprogrammable microchips, with the use of a simple electrical circuit.
