Explained: How HDMI cable can allow hackers to ‘see’ your passwords

Researchers in Uruguay discovered a method using AI to intercept video signals from HDMI cables by capturing electromagnetic radiation emissions. Despite HDMI’s encryption, the ‘Deep-TEMPEST’ method successfully decoded EM radiation, achieving up to 70% accuracy. Though not perfected, this poses potential security risks, highlighting the need for EM-shielding measures in the future.
