In 2014, researchers introduced ″AirHopper″, a bifurcated attack pattern showing the feasibility of data exfiltration from an isolated computer to a nearby mobile phone, using FM frequency signals. [5] [6] In 2015, "BitWhisper", a covert signaling channel between air-gapped computers using thermal manipulations, was introduced.
