Users normally find wired connections more secure compared to wireless connections. Some researchers in Uruguay have found a method to intercept video signals from HDMI cables using AI (artificial intelligence).
HDMI cables are a wired standard and typically encrypted, they still release electromagnetic (EM) radiation.
This unintentional leakage can be hacked and decoded by hackers to unveil the transmitted video content. This method is called TEMPEST (Transient Electromagnetic Pulse Emanation Standard).

What is TEMPEST?
TEMPEST is a security standard that informs the risk of electronic eavesdropping through unintentional electromagnetic emissions from electronic devices.
These emissions, which can be intercepted and decoded, potentially unveil sensitive details like displayed video content, keystrokes, or other data.
What users can do?
To reduce these risks, users should apply EM-shielding measures. This might add physical shielding for cables and equipment or even modify workplaces to minimise EM leakage. Presently, remote works are preferred, which indicates to ensure the security of home cables.
