How To Keep Web Sites From Listening To Your Microphone [OS X Tips]



Last week, a speech recognition developer found a potential exploit in the Chrome web browser that could possibly let malicious web sites activate your Mac’s microphone and listen in on any sounds your mic might pick up around you. Even if you’re not actively using your computer, the mic could be active and conversations, meetings, and phone calls could potentially be recorded or listened in on.

Luckily, there’s a way to keep this from happening, because–however remote the possibility–it’s always a good idea to keep your private information, including real-world conversations, private.

Of course, if you don’t use the Chrome browser at all, this won’t apply to you.
