“Attackers Can Use HVAC Systems to Control Malware on Air-Gapped Networks”

An attack scenario by the name of “HVACKer” in which heating, ventilation, and air conditioning systems are used to connect air-gapped networks with the external environment has been demonstrated by researchers at Ben-Gurion University of the Negev. This connection would allow attackers to remotely transmit commands to malware installed on a computer within the targeted isolated network. This article further discusses the details of this attack scenario in relation to its process, capabilities, and level of impact, along with other demonstrations and incidents of this type of attack.
