Most computers, whether desktop or laptop,have a series of connectors (Jacks) audio, on both the front panel and the rear panel or both. Each socket is used both for input (line input) as for departure (line output). It is currently possible to change the function of an audio port using software that allows programming, this software is called “Jack Retasking” or “Jack Remapping”.
Malware has been developed (harmful program) that can reconfigure the headphone jack from a line-out jack as a microphone jack, making the connected headphones work as a pair of recording microphones and turning our computer into a spying device, not needing a connected microphone.
to work around this problem we recommend that you install software that allows you to fully disable the audio hardware (sound card), or use an audio driver that warns us when trying to access the microphones without our permission and develop a strict control by the manufacturer that does not allow the audio connectors of our computers to be easily manipulated. Intrusion detection systems could also be developed that attempt to maliciously switch from speaker to microphone and block them.
