In this age of technological progress, spying on people has become easier simple. Therefore, there are more and more supporters of theories conspiracies that stick stickers on the eyes of their webcams and most of the time keep mics muted.
However, Israeli security experts report that in in order to avoid surveillance, this is not enough. Turns out to eavesdrop an ordinary user of a personal computer can also be headphones.
“How so?” You ask. “After all, an earphone represents sound output device, not input. To eavesdrop on someone microphone is required. ”
