New TrojPix Attack Leaks Data From Air-Gapped Systems via Video Cable Emissions
Medium
Summary
Researchers at Shandong University have developed a new technique called TrojPix that allows data to be exfiltrated from air-gapped systems by subtly modulating pixels on a screen and transmitting them as a radio signal. This method bypasses traditional network defenses and requires only malware already present on the target machine. While not a method of initial intrusion, it provides a significant avenue for data exfiltration once an attacker has gained access.
