TrojPix: How a video cable becomes a data exfiltration channel from air-gapped systems

Colleagues, I’d like to draw your attention to a cybersecurity update.

Researchers have demonstrated TrojPix — a technique that subtly alters on-screen pixels and causes a video cable to emit a signal that can be read near the computer.

Important: the attack does not break the air gap directly. The machine must already be infected with malware capable of controlling the display.

In tests, exfiltration speed reached 8.1 Mbps, with a range of up to 208 meters. This is no longer about isolated passwords, but about rapidly removing files.

Why it matters: organizations need to protect not only the network, but also the physical environment, cables, and the initial point of compromise.

What do you think — are companies ready for such covert channels?
