Query: AiR-ViBeR: Exfiltrating Data from Air-Gapped Computers via Covert
  Surface ViBrAtIoNs   Air-gap covert channels are special types of covert communication channels
that enable attackers to exfiltrate data from isolated, network-less computers.
Various types of air-gap covert channels have been demonstrated over the years,
including electromagnetic, magnetic, acoustic, optical, and thermal.
  In this paper, we introduce a new type of vibrational (seismic) covert
channel. We observe that computers vibrate at a frequency correlated to the
rotation speed of their internal fans. These inaudible vibrations affect the
entire structure on which the computer is placed. Our method is based on
malware's capability of controlling the vibrations generated by a computer, by
regulating its internal fan speeds. We show that the malware-generated covert
vibrations can be sensed by nearby smartphones via the integrated, sensitive
\textit{accelerometers}. Notably, the accelerometer sensors in smartphones can
be accessed by any app without requiring the user permissions, which make this
attack highly evasive. We implemented AiR-ViBeR, malware that encodes binary
information, and modulate it over a low frequency vibrational carrier. The data
is then decoded by malicious application on a smartphone placed on the same
surface (e.g., on a desk). We discuss the attack model, provide technical
background, and present the implementation details and evaluation results. Our
results show that using AiR-ViBeR, data can be exfiltrated from air-gapped
computer to a nearby smartphone on the same table, or even an adjacent table,
via vibrations. Finally, we propose a set of countermeasures for this new type
of attack.
