Apple exposed new vulnerabilities, activate the camera LED lights into a display"

According to foreign media reports, recently, security researcher Johns Hopkins University found new means of attack against Macbook and iMac series models, the activation of iSight cameras without the need to open the camera with the LED light through the custom firmware to input. Washington Post quoted the title "research article in iSeeYou: Disabling the MacBook security Webcam Indicator LED" Matthew Brocker and Stephen Checkoway to the main control chip firmware for camouflage iSight camera, and then control the camera in the case of LED enabled light is not open.

The iSight camera system designed by apple, named "hardware interlock" (hardware interlock) technology allows the camera sensor and built-in LED bundle, and LED link directly to the sensor so both in the open and closed all belong to the same state. But two security researchers to the iSight camera firmware has been re written to bypass the "hardware interlock" in time after USB port communication, shooting to activate the camera can not open in the case of LED lighting.
