RESEARCHER: Software can turn headphones into a MICROPHONE and let hackers listen in from across a room
A new experiment demonstrates how easily hackers can turn your headphones into a microphone to unknowingly eavesdrop in background.
Researcher designed a code called ‘Speake(a)r, which ‘retasks’ a computer’s outputs to inputs – allowing them to record audio even when the headphones were in the output-only jack.
The team used a pair of headphones to capture vibrations in the air and converted them to electromagnetic signals to record audio from 20 feet across a room.
