(June 24, 2016) Researchers in Israel have recently created malware call Fansmitter and hijacked computer fans to transmit data.
According to PCWorld.com, “The research from Ben-Gurion University of the Negev shows how data could be stolen from “air-gapped” computers, which are not connected to the Internet” by manipulating the sounds fans create.
Fansmitter can secretly send data over “audio waves generated by computer fans”, and “works by controlling the speed at which the fans run. This can create varying acoustic tones that can be used to transmit the data,” reported PCWorld.
“To receive the data, the hackers would need to compromise a nearby mobile phone. This phone could then decode the noise from the fans, assuming the device is close enough to the sound or within eight meters,” PCWorld explained, “Once the noise is decoded, the phone could then relay all information back to the hackers.”
