Abstract | In this paper we present LANTENNA - a new type of an electromagnetic attack allowing adversaries to leak sensitive data from isolated, air-gapped networks. Malicious code in air-gapped computers gathers sensitive data and then encodes it over radio waves emanated from Ethernet cables. A nearby receiving device can intercept the signals wirelessly, decodes the data and sends it to the attacker. We discuss the exiltration techniques, examine the covert channel characteristics, and provide implementation details. Notably, the malicious code can run in an ordinary user mode process, and can successfully operates from within a virtual machine. We evaluate the covert channel in different scenarios and present a set of of countermeasures. Our experiments show that with the LANTENNA attack, data can be exfiltrated from air-gapped computers to a distance of several meters away. |
