What is HDMI cable?

An HDMI cable stands for High-Definition Multimedia Interface. It’s a single cable that can transmit both audio and video between devices. Unlike older analog interfaces, HDMI transfers uncompressed digital video and audio without any loss of quality. Plus, newer HDMI cables can even carry internet connectivity1. So, think of it as the go-to cable for connecting your Blu-ray players, game consoles, and streaming devices to your TV!

how HDMI cable allow hackers to see your password?

Certainly! While HDMI cables are typically considered secure due to encryption, they unintentionally emit electromagnetic (EM) radiation. Researchers in Uruguay discovered a method called TEMPEST (Transient ElectroMagnetic Pulse Emanation STandard) that allows hackers to capture and decode this radiation. By using readily available radio equipment and AI, they can intercept video signals from HDMI cables and potentially reveal transmitted video content1. Although this technique isn’t perfected yet, it highlights the need for future EM-shielding measures to enhance security. So, while HDMI cables themselves don’t directly expose passwords, their unintended emissions could pose risks if exploited by skilled attackers.
