• Digital microphones in laptops, phones, and smart speakers unintentionally broadcast electromagnetic signals that can be intercepted up to 2 meters away, even through walls.
• The attack is surprisingly accessible: Researchers achieved over 94% accuracy in speech recognition using simple equipment like copper tape antennas, making this vulnerability exploitable by anyone with basic technical knowledge.
• Your “off” microphone might still be listening: Testing revealed that microphones often activate automatically when playing audio or video content, and some remain active even when apps appear muted. more
