COVID-bit: Keep a Distance of (at least) 2m From My Air-Gap Computer!
Mordechai Guri
Air-gapped systems are isolated from the Internet due to the sensitive information they handle. This paper presents COVID-bit, a new COVert channel attack that leaks sensitive info…
LANTENNA: Exfiltrating Data from Air-Gapped Networks via Ethernet Cables
Mordechai Guri
Air-gapped networks are wired with Ethernet cables since wireless connections are strictly prohibited. In this paper we present LANTENNA - a new type of electromagnetic attack allo…
AIR-FI: Generating Covert Wi-Fi Signals from Air-Gapped Computers
Mordechai Guri
In this paper, we show that attackers can exfiltrate data from air-gapped computers via Wi-Fi signals. Malware in a compromised air-gapped computer can generate signals in the Wi-F…
POWER-SUPPLaY: Leaking Data from Air-Gapped Systems by Turning the Power-Supplies Into Speakers
Mordechai Guri
It is known that attackers can exfiltrate data from air-gapped computers through their speakers via sonic and ultrasonic waves. To eliminate the threat of such acoustic covert chan…
AiR-ViBeR: Exfiltrating Data from Air-Gapped Computers via Covert Surface ViBrAtIoNs
Mordechai Guri
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…
BRIGHTNESS: Leaking Sensitive Data from Air-Gapped Workstations via Screen Brightness
Mordechai Guri, Dima Bykhovsky, Yuval Elovici
Air-gapped computers are systems that are kept isolated from the Internet since they store or process sensitive information. In this paper, we introduce an optical covert channel i…
