SemCovert: Secure and Covert Video Transmission Via Deep Semantic-Level Hiding

Video semantic communication, praised for its transmission efficiency, still faces critical challenges related to privacy leakage. Traditional security techniques like steganography and encryption are challenging to apply since they are not inherently robust against semantic-level transformations...

CovertAuth: Joint Covert Communication and Authentication in MmWave Systems

Beam alignment BA is a crucial process in millimeter-wave mmWave communications, enabling precise directional transmission and efficient link establishment. However, due to characteristics like omnidirectional exposure and the broadcast nature of the BA phase, it is particularly vulnerable to...

Air-Gapped Devices Can Send Covert Morse Signals via Network Card LEDs

A security researcher who has a long line of work demonstrating novel data exfiltration methods from air-gapped systems has come up with yet another technique that involves sending Morse code signals via LEDs on network interface cards NICs. The approach, codenamed ETHERLED, comes from Dr...

GhostTunnel - A Covert Backdoor Transmission Method That Can Be Used In An Isolated Environment

GhostTunnel is a covert backdoor transmission method that can be used in an isolated environment. It can attack the target through the HID device only to release the payload agent, then the HID device can be removed after the payload is released. GhostTunnel use 802.11 Probe Request Frames and...
