iSight fright might blight your night.
Apple (NASDAQ:AAPL) webcams are vulnerable to silent malware attack. It's long been believed that nobody can turn on your iSight webcam without the light illuminating. However, security researchers have shown that to be false. They say the design flaw isn't only limited to the earlier models that they demonstrated it on.
