Security researchers discovered a new way to hack the Mac’s built-in webcam this week, and the method is undetectable by users.
Apple built a green LED light into every Mac with firmware-level protection that turns on anytime the sensor is tripped by unauthorized access. The security feature has become increasingly difficult for hackers to beat, but former NSA staffer Patrick Wardle found a way to piggyback on outgoing feeds and record them.
Apple’s Gatekeeper feature was designed to keep even the most advanced users from accidentally installing malicious software on their computers, but a super-simple exploit lets hackers sneak malware onto your Mac.
The exploit was discovered by Patrick Wardle, director of research at security firm Synack. Wardle found that the exploit is made possible thanks to a key design shortcoming in Gatekeeper that lets an attacker use a binary file already trusted by Apple to execute malicious files.
