"All joking aside, malware that can spread or receive commands through sound seems like something out of a far-fetched sci-fi movie right? Not according to researchers at the University of Alabama at Birmingham (UAB) who have recently released a paper entitled Sensing-Enabled Channels for Hard-to-Detect Command and Control of Mobile Devices. The paper examines how malware on mobile devices can be activated and controlled using non-Internet channels such as sound, light, magnetic fields, and vibration. Traditional means of controlling malware rely on network-based channels, such as a TCP/IP based channel, that are easily detected and blocked by firewalls and antimalware products, whereas the methods put forward by the UAB researchers would be extremely difficult, if not impossible, to detect."
