Researchers have demonstrated a novel attack vector called 'Pwnd Blaster' that can compromise computers through their built-in speakers without physical access. The technique exploits electromagnetic emissions from speakers to inject malicious code, representing a significant advancement in air-gapped system vulnerabilities. This discovery highlights new security challenges in protecting sensitive systems from non-traditional attack surfaces.
Background
Air-gapped computers are physically isolated from unsecured networks to protect sensitive data, but researchers continue to find creative ways to breach these systems using unconventional methods like electromagnetic emissions, sound waves, and other side-channel attacks.
