An attacker able to inject untrust...

TEMPEST-LoRa: Cross-Technology Covert Communication

Electromagnetic EM covert channels pose significant threats to computer and communications security in air-gapped networks. Previous works exploit EM radiation from various components e.g., video cables, memory buses, CPUs to secretly send sensitive information. These approaches typically require...

New PIXHELL Attack Exploits LCD Screen Noise to Exfiltrate Data from Air-Gapped Computers

A new side-channel attack dubbed PIXHELL could be abused to target air-gapped computers by breaching the "audio gap" and exfiltrating sensitive information by taking advantage of the noise generated by pixels on an LCD screen. "Malware in the air-gap and audio-gap computers generates crafted pixe...
