New Malware Capable of Jumping Airgaps Using USB, Speakers, & Microphones – Impossible to remove.
Security consultant Dragos Ruiu has spent the past three years working to understand malware that is able to jump network airgaps. Based on what has been reported the malware apparently uses USB drives to transmit and then the speakers and microphone on computers to transmit high frequency signals. The malware is able to infect windows, mac or *nix machines and to remove it from a network is next to impossible.
If this is a hoax it is a darn good one running deep into the security community. Jeff Moss (DefCon founder, DHS Cyber Security advisor) has gone on the Twitter record re-tweeting Ruiu’s posts and adding “No joke it’s really serious.”
