A security researcher has demonstrated a novel method for exfiltrating data from air-gapped systems using the blinking lights of a keyboard. By manipulating the keyboard's LED indicators, such as Caps Lock or Num Lock, an attacker can encode and transmit data wirelessly, bypassing traditional air-gap security measures. This technique highlights a new class of potential vulnerabilities in highly secured environments. AI
