No, not a joke. As told in Ars Technica, researchers are developing a new type of malware that would spread through the sound devices of the team. This is inaudible to humans that colaría for audio inputs like microphone or speakers signal.
Apparently this malware prototype created by a German research department, can transmit small amounts of data-enough to send a keylogger , for example-as audio signals, which depending on infrastructure, have a range of from 20m .
Therefore, this malware to be effective, the attacker would be very close to his victim, even with the use of repeaters the maximum distance may be greater.
only user of GNU / Linux would supposedly safe from an attack of this kind, because it actually current operating systems are not prepared for these techniques edge. I explained in the extensive report (PDF) published: configuring ALSA in a particular way, the immune system would be
Why not explain in detail the method of protection? Because, dear @ s @ s reader MuyLinux, this is nothing more than a curiosity that you should not worry for a moment … for now. For the future, however, it is worth having the knowledge of where the shots. Or the malware in this case.
