Dell: TrojPix Attack Uses Imperceptible Pixels to Steal Data From Air-Gapped Networks

TrojPix: New EM Covert-Channel Attack Exfiltrates Data from Air-Gapped Networks at Unprecedented Speeds Researchers at USENIX Security have unveiled TrojPix , a novel electromagnetic (EM) covert-channel attack that exploits invisible pixel modulation to steal data from air-gapped systems networks physically isolated from external connections. The technique turns standard digital video cables
