ETHERLED: Air-gapped systems leak data via network card LEDs
From https://www.bleepingcomputer.com/new...ork-card-leds/
Quote:
Israeli researcher Mordechai Guri has discovered a new method to exfiltrate data from air-gapped systems using the LED indicators on network cards. Dubbed 'ETHERLED', the method turns the blinking lights into Morse code signals that can be decoded by an attacker.
Capturing the signals requires a camera with a direct line of sight to LED lights on the air-gapped computer's card. These can be translated into binary data to steal information.
