Researchers at\u00a0Shandong University\u00a0have shown a fast new way to pull data off computers that are cut off from every network. The technique, called\u00a0TrojPix, tweaks on-screen pixels in ways the eye cannot see, so that the video cable carrying them radiates a faint radio signal a nearby receiver can decode.<\/p>\n

But TrojPix works only once malware is already on the target machine, so it is a way for stolen data to get out, not a way in. In the researchers’ tests, TrojPix hit a peak throughput of 8.1 Mbps and reached as far as 208 meters, the two measured separately rather than together.<\/p>\n

Most air-gap covert channels crawl along at bits or kilobits per second; at 8.1 megabits, roughly a megabyte a second, TrojPix could move a 100 MB file in under two minutes. That turns the threat from leaking a password into moving whole files while the monitor looks switched off.<\/p>\n

Real-world range is another matter: a receiver still has to fight through walls, shielding, and noise.<\/p>\n

The method, which the researchers call imperceptible pixel modulation, needs no administrator rights and no hardware changes, they say; user-level malware that can draw to the screen is enough.<\/p>\n

They describe two ways to hide the traffic. One fakes a powered-off display, keeping the screen dark while it transmits. The other buries the signal in whatever is already on screen, so ordinary-looking content carries the payload.<\/p>\n

The team reports it is working across nine monitor brands and fifteen video cables, so the result is not tied to one setup.<\/p>\n

Turning a video cable into a covert transmitter is not new. It traces back to the decades-old study of compromising emanations, known as TEMPEST, and more recently to work like\u00a0TEMPEST-LoRa\u00a0(CCS 2025), which used the same trick to reach off-the-shelf LoRa radios, a common long-range wireless standard.<\/p>\n

That one topped out at 87.5 meters, or 21.6 kbps. TrojPix’s peak throughput is hundreds…<\/p>\n
