Fansmitter: Acoustic Data Exfiltration from (Speakerless) Air-Gapped Computers
Because computers may contain or interact with sensitive information, they are often air-gapped and in this way kept isolated and disconnected from the Internet. In recent years the ability of malware to communicate over an air-gap by transmitting sonic and ultrasonic signals from a computer speaker to a nearby receiver has been shown. In order to eliminate such acoustic channels, current best practice recommends the elimination of speakers (internal or external) in secure computers, thereby creating a so-called ‘audio-gap’. In this work, we present Fansmitter, a malware that can acoustically exfiltrate data from air-gapped comput...
