Malware can turn your computers into perpetual eavesdropping devices by turning your speakers and headphones/earphones into microphones.
Researchers in Israel based university Ben-Gurion University of the Negev have shown the potential of PCs to be attacked by a malware called ‘SPEAKE(a)R’. Headphones and earphones are physically built like microphones, and reprogramming of the audio port can change the functioning from output to input. This kind of susceptible virus can be misused by hackers.
The reason why most social media users tape up their webcam and microphone is so that hackers cannot watch them even if their computer is hacked by a third party. You can read about it in detail here mentioned in our previous article. Taping is a solution to the webcam issue, however, how do you avoid getting hacked via headphones?
A normal daily usage computer contains at least one audio jack,either in front panel or rear panel. Each jack is configured for line-in or line-out,as in audio in or audio out. This malware can re configure your PC from a headphone jack to a microphone jack,turning the computer into a pair of recording machine and a perfect eavesdropping device. This is functional even when the PC isn’t connected to any mic.
The ones used in crime thriller movies are actually harmful in real lives, if misused, can take away our utmost cherished human right, that is, privacy.
