Security researcher discovers badBIOS malware that jumps using microphone and speakers
(Phys.org) —Highly respected Canadian security expert Dragos Ruiu has been fighting, he claims, an unknown bit of malware that that appears to run on Windows, Mac OS X, BSD and Linux, for approximately three years. After much research and effort, which he has been documenting using several online venues (mainly Twitter), he says he believes the malware infects computers via memory sticks, and vice versa. He says also that he's found evidence that the malware is able to create mini-networks between infected machines using high frequency sound waves that are passed from a computer's microphone to another's speakers, and vice-versa. Unfortunately, at this time, Ruiu is the only person that appears to know about the malware, which he has dubbed badBIOS.
