xLED: Covert Data Exfiltration from Air-Gapped Networks via Router LEDs

Mordechai Guri, Boris Zadov, Andrey Daidakulov +1

In this paper we show how attackers can covertly leak data (e.g., encryption keys, passwords and files) from highly secure or air-gapped networks via the row of status LEDs that ex…

LED-it-GO: Leaking (a lot of) Data from Air-Gapped Computers via the (small) Hard Drive LED

Mordechai Guri, Boris Zadov, Eran Atias +1

In this paper we present a method which allows attackers to covertly leak data from isolated, air-gapped computers. Our method utilizes the hard disk drive (HDD) activity LED which…
