■■■■■ Hackers can wirelessly watch your display by HDMI radiation.
Known side-channel attack called TEMPEST (Transient Electromagnetic Pulse Emanation Standard). It involves capturing electromagnetic signals emitted by electronic devices, including HDMI cables, and reconstructing the displayed content.
Key points:
Poorly shielded HDMI cables can emit detectable radiation.
With specialized equipment, attackers can intercept these emissions wirelessly.
Shielded cables and secured environments significantly reduce this risk. https://www.pcworld.com/article/2413156/hackers-can-wirelessly-watch-your-screen-via-hdmi-radiation.html
