Malware jumps 'air gap' between non-networked devices
Researchers create proof-of-concept software to show how standalone computers can communicate via built-in speakers and microphones.

Using the microphones and speakers on a pair of Lenovo T400s, the researchers adapted software originally created to facilitate robust underwater communications. Originally developed by the Research Department for Underwater Acoustics and Marine Geophysics and based on an open-source development toolkit for signal processing, the adaptive communication system modem was able to transmit data of 20bps up to 19.7 meters (64.6 feet) apart. Greater distances could be achieved by forming an acoustical mesh network with the addition of nearby devices to the chain.
