- Unsuspecting listen to a song on your computer can be more dangerous than previously thought. These headphones can be hacked and changed into a microphone. Others can then listen in unnoticed. That reports TechCrunch.
Researchers at Ben Gurion University in Israel have discovered the technique. They call it 'speake (a) r' ', a contraction of speaker and ear. It works by adjusting the sound card in a computer. If the output is changed to input in the audio actually the other way, not from the computer to the user, but the other way around. And by the sound settings this is unavoidable. The hacker got to be around to catch the sound, the signal can only come a few meters away.
