It has been assumed that the physical separation ('air-gap') of computers provides a reliable level of security, such that should two adjacent computers become compromised, the covert exchange of data between them would be impossible. [] Key Method Our method is unique in two respects: it supports bidirectional communication, and it requires no additional dedicated peripheral hardware. We provide experimental results based on the implementation of the Bit-Whisper prototype, and examine the channel's…

BitJabber: The World’s Fastest Electromagnetic Covert Channel

A new physical covert channel named BitJabber is introduced that is extremely fast and strong enough to even penetrate concrete walls and can enable data exfiltration from an air-gapped computer enclosed in a room with thick concrete walls up to 15 cm.

Air-Gap Covert Channels

It is empirically demonstrated that using physically unmodified, commodity systems, covert-acoustic channels can be used to communicate at data rates of hundreds of bits per second, without being detected by humans in the environment, and data rates when nobody is around to hear the communication.

The results show that attackers can use the SATA cable to transfer a brief amount of sensitive information from highly secured, air-gap computers wirelessly to a nearby receiver.

GSMem: Data Exfiltration from Air-Gapped Computers over GSM Frequencies

GSMem, a malware that can exfiltrate data through an air-gap over cellular frequencies, is presented and its efficacy and feasibility are demonstrated, achieving an effective transmission distance of 1 - 5.5 meters with a standard mobile phone.

The experiment shows that sensitive data can be covertly leaked via the status LEDs of switches and routers at a bit rates of 10 bit/sec to more than 1Kbit/sec per LED.

SpiralSpy: Exploring a Stealthy and Practical Covert Channel to Attack Air-gapped Computing Devices via mmWave Sensing

S SpiralSpy is presented, a new covert channel to attack air-gapped computing devices through millimeter-wave (mmWave) sensing technologies and can be adopted on multiple-fan systems and enable a scalable capacity for multi-channel and high-speed information transfer.

On the capacity of thermal covert channels in multicores

A new methodology is devised and exploited that leverages both theoretical results from information theory and experimental data to study these thermal covert channels on modern multicores and shows a communication scheme that achieves rates of more than 45 bps on the same-core channel and more than 5 bPS on the 1-hop channel with less than 1% error probability.

MagView: A Distributed Magnetic Covert Channel via Video Encoding and Decoding

This paper proposes MagView, a distributed magnetic cover channel, where sensitive information is embedded in other data such as video and can be transmitted over the air-gapped internal network, and demonstrates that CPU utilization for video decoding can be effectively controlled by changing the video frame type and reducing the quantization parameter without video quality degradation.

This work suggests the same technique could be exploited as a classical covert channel and can even provide geolocation, because existing abstract models of anonymity-network nodes do not take into account the inevitable imperfections of the hardware they run on.
