New TrojPix Attack Leaks Data From Air-Gapped Systems via Video Cable Emissions

Researchers at Shandong University have demonstrated a new data exfiltration technique called TrojPix, which leverages video cable emissions to leak data from air-gapped systems by modulating on-screen pixels imperceptibly. The method requires prior malware presence on the system but does not need admin rights or hardware modifications, enabling data transmission at up to 8.1 Mbps over distances up to 208 meters. This technique represents a significant advancement in covert channel speed and range, though it remains experimental and not yet observed in real-world attacks.
